Direct Box - Musical Instrument Adaptor

The <span style="font-weight: bold;">Countryman Type 10 DI</span> box is
 the ideal counterpart to the classic Type 85, combining the exceptional
 ruggedness and versatility of the Type 85 with an advanced design that 
sets a new standard for pure performance.<br>
<br>
Most direct box designs must make difficult tradeoffs with your sound: 
ultra-low distortion can only be attained by increasing input noise; 
true ground isolation means high phase deviation or signal attenuation. 
The Type 10 takes a radically new approach, with an analog circuit that 
tunes itself to deliver your sound with the lowest distortion, lowest 
noise, and highest accuracy of any direct box. The result is a clean, 
precise sound that is completely faithful to the original.<br>
<br>
<span style="font-weight: bold;">Outstanding Performance</span><br>
The Type 10 achieves the highest SNR, lowest phase deviation, and lowest
 distortion of any DI. Some boxes achieve low distortion over a narrow 
range of frequencies and levels, but end up coloring the low frequencies
 and distorting loud signals. The Type 10 maintains exceptionally low 
THD and IMD across the entire audio band, and for a wide range of input 
voltages, rendering your sound with extremely high fidelity.<br>
<br>
<span style="font-weight: bold;">Frequency Response:</span><br>
<ul><li>10Hz - 50kHz (+/- 1dB)</li></ul>
<br>
<span style="font-weight: bold;">Deviation from Linear Phase:</span><br>
<ul><li>+2 deg (30 Hz)</li><li>0 deg (100 Hz - 20 kHz)</li><li>Noise (short input, 22 Hz - 20 kHz):</li><li>1.8 micro-Volts rms</li></ul>
<br style="font-weight: bold;">
<span style="font-weight: bold;">THD (1Vpp, typical load):</span><br>
<ul><li>< 0.001% at 1 kHz</li><li>< 0.005% (30 Hz - 20 kHz)</li></ul>
<br style="font-weight: bold;">
<span style="font-weight: bold;">IMD (1Vpp, typical load):</span><br>
<ul><li>< 0.005% (10 kHz/60 Hz, 4:1)</li></ul>
<br>
<span style="font-weight: bold;">Max Input (1% THD):</span><br>
<ul><li>6 Vpp (0 dB pad)</li><li>33 Vpp (-15 dB pad)</li><li>190 Vpp (-30 dB pad)</li></ul>
<br>
<span style="font-weight: bold;">Indestructible</span><br>
Like the Type 85, the Type 10 is armored inside and out, with a molded 
core wrapped in an extra thick architectural alumininum housing. The 
switches and connectors are fully recessed. The electronics are just as 
tough—both the Type 10 and the Type 85 shrug off static spikes and will 
survive with the input connected directly to 110V or 220V line voltage.<br>
<br>
<span style="font-weight: bold;">Versatile</span><br>
We understand that conditions on the road are not always ideal—noisy 
electrical systems, mix boards positioned across a stadium with low 
input impedance and low or no phantom power for your box. The Type 10 
has rock solid isolation and is designed to drive any board across 
hundreds of feet of cable whether or not you have phantom power. That 
means that whatever environment you’re in, your sound will be 
consistently great.<br>
<br>
<span style="font-weight: bold;">Pure and Simple</span><br>
The legendary Type 85 achieves greatness partly through its simplicity: 
no unnecessary roll-off switches or EQ options. With the new Type 10, we
 kept it simple while adding some new features that we think can really 
help you on the road. Handle sizzling hot outputs from active keyboards 
using the -15 dB pad with virtually immeasurable distortion. Use the 
edge of a coin to access the battery. Check the battery voltage and 
monitor the quality of the phantom power with the flip of a switch.

The <span style="font-weight: bold;">D.W. Fearn LP-1 Line Pad</span> is a two-channel accessory for use with the VT-1 or VT-2 Vacuum Tube Microphone Preamplifiers. It is simply a high-quality bridging-type pad that accepts line-level inputs (+4 dBm nominal) and produces a mic level output. The actual pad loss is 45 dB. When used in conjunction with the VT-1 or VT-2 Input Pad (-20 dB), it allows the mic preamp to accomodate line-level signals from consumer-level (-10 dBV) to high professional levels (+10 dBm or more).
<p>
The LP-1 is packaged in a heavy-duty die-cast aluminum box, painted with the same high-quality red paint and gold silk-screened labels as the other D.W. Fearn products. The Input and Output connectors are gold-contact XLR. 
</p><p>
 The LP-1 is typically used when the subtle signal-modifying characteristics of the VT-1 or VT-2 are needed on a line-level source, such as a previously-recorded track, or at the end of a processing chain. Several LP-1/VT-2 owners use the combination on the overall mix. At least one CD mastering facility uses the LP-1/VT-2 in the mastering chain. 
</p><p>
 The LP-1/VT-2 combination can also often be used to effectively salvage tracks that are otherwise too distorted or "edgy" for master use.</p>

The VT-3 is a dual-channel, all-triode vacuum tube DI (“direct box”) for recording electric or electronic instruments. The inputs are designed to provide the proper load impedance for all instruments that have a 1/4-inch phone jack output. Tube circuitry provides the very high impedance necessary to capture all the details of these instruments.
The outputs of the VT-3 are mic level (150 ohm source impedance at a nominal -30dBV). The VT-3 is designed to operate into a high-quality microphone preamplifier like our VT-1 and VT-2 Vacuum Tube Microphone Preamplifiers.
<p>
Operation is very simple: plug the instrument into the 1/4” front panel jack and take the output either from the front panel XLR connector, or a parallel XLR connector on the back panel. A second 1/4” jack provides an output to feed a guitar amplifier when necessary. A ground-lift switch helps eliminate ground loop buzz, and a switchable high-pass filter gently rolls off frequencies below 100Hz when required.
</p><p>
The two channels are entirely independent and can be used with two different instruments at the same time.</p>

The <span style="font-weight: bold;">Little Labs Redeye 3D Phantom</span>
 is the new improved major revision of the popular Little Labs Redeye 
direct box / re-amp box. More people are re-amping now than ever before,
 and we at Little Labs know re-amping! We made this new major Redeye 
revision because we wanted to make sure we continued to make the best 
sounding, most flexible, easiest to use, and reasonably priced re-amping
 and direct box product available.<br>

<br>

<span style="font-weight: bold;">Features</span><br>

<ul><li>Simultaneous vintage transformer direct box and re-amping tool</li><li>Compare direct and re-amped signal with one button</li><li>Phantom powered super hi fi buffered or passive direct box inputs</li><li>What you heard is what you will hear easy re-amping operation</li><li>Easily interfaces pro gear with guitar gear and vice versa</li><li>Expandable for daisy chaining redeyes to feed multiple amps or pedals</li><li>Rack mountable 4 redeyes fit in a 1U space</li></ul>

For easy accurate re-amping the Redeye 3D lets you listen thru your 
whole recording chain, from Redeye 3D direct box, to mic pre to DAW (or 
tape machine), to Redeye 3D Re-amp, to your guitar amp. In DI (direct 
box) mode the instrument / re-amp out on the front of the Redeye 3D 
works as a thru signal so you can simultaneously feed your guitar amp 
while supplying a signal from the rear xlr to your mic pre and DAW or 
tape machine. In re-amp mode the instrument / re-amp out on the front of
 the Redeye 3D signal comes from the line level output of the DAW or 
tape machine (converted to HI z guitar level signal) to feed your guitar
 amp. This simple way of listening thru the chain (re-amp mode) and 
being able to bypass the mic pre and DAW or tape machine in the chain 
(DI mode) makes level adjustments a snap. This also assures you a 
re-amped guitar sound that will be exactly what was heard when laying 
down the track.<br>

<br>

The heart of the original Redeye was a Little Labs custom wound 
transformer. This transformer was chosen for its sonic characteristics 
and is made with the same core material and winding technique as the 
legendary UTC transformers found in many classic pro audio devices. The 
Redeye 3D features two of these excellent transformers for simultaneous 
direct box and re-amping use. We have also added to the Redeye direct 
box a very high quality, hi fi, phantom powered, high impedance (10MΩ) 
instrument buffer. When you are using the Redeye with sensitive passive 
or piezo pick ups, this high quality buffer assures no tone change from 
loading will occur. For those who use active pick ups or prefer the 
sound of a passive direct box, you still have the option of plugging 
into the Redeye 3D direct box passively as in the original Redeye. The 
Redeye 3D sounds amazing and even if you never used it for re-amping it 
is an incredible value just as a direct box.<br>

The <span style="font-weight: bold;">Little Labs STD</span> allows you to use long microphone cables or microphone tie lines to extend your guitar or any instrument cable without the loss of tone and increase of noise associated with long instrument cable runs. It also has two outputs for splitting between two amps or between an amp and a direct injection box, with a selectable ground lift on one output to eliminate ground loop problems.<br><br>The STD is the perfect solution for: the live player who is tired of the tone sucking wireless rigs but still needs to be able to walk more than ten feet from his amp; the studio player who needs his amplifier in isolation, but himself in close proximity to his band mates; the recording engineer using control room rack mounted direct injection boxes with a player located in the studio or isolation booth.<br><br>The single transistor unity gain buffer circuit utilized in the STD is mounted inside the special copper tipped phone plug itself. This elegantly simple buffer circuit was designed to load the instrument pickup properly for a natural frequency response regardless of cable length and also will eliminate susceptibility of the cable to extraneous noise sources. The rugged cast aluminum base unit which sits next to the amp or direct injection box contains the mating circuitry which utilizes high quality audio graded parts, including Elna Cerafine and Dale Vishay. The STD base unit is powered by two nine volt batteries that with regular use will last over one year. <br><br>Little Labs once again has addressed a common studio and live sound problem with a simple effective and reasonably priced solution.

As the Martech MSS-10 Microphone Preamplifier became popular with
discerning users, requests increased for a direct box that would give
them that same “high fidelity with soul” they love about their MSS-10s.<br>
<br>
Staying true to the design of the MSS-10, the <span style="font-weight: bold;">MartinSound MSS-01</span>
starts by using the same custom transformer to provide a sonically
superior passive path that accommodates both balanced and unbalanced
sources, and then adds a German microphone quality active input to
lighten the load when required for vintage guitars.<br>
<br>
Join the hit makers who have already discovered magic in the Martech
Modular Studio Series. Experience the artistic satisfaction from using
an MSS-01 and turn your dreams into legend.<br>
<br>
<span style="font-weight: bold;">Another Direct Box?</span><br>
At Martinsound we build and offer exclusively to our studio clients, a
passive direct box based on the design of our renowned Martech MSS-10
Microphone Preamplifier. Musicians, engineers, and producers who try it
agree that our direct box sounds bigger, clearer and more open than the
high-end boxes they bring to the sessions. With no surprise, demand
grew for a commercial version.<br>
<br>
A transformer is used in a passive direct box to match the high
impedance output of an instrument to the low impedance input of a mic
preamp. By lowering the impedance of the signal, it is less susceptible
to interference and can drive longer distances without reacting to
cable capacitance, thus preventing high frequency loss. The transformer
also reflects a proportionally higher input impedance from the mic
preamp, lessening the load on the instrument.<br>
<br>
The Martech MT-1005 input transformer has a 10:1 ratio, dividing the
output impedance of the instrument by 100 while multiplying the mic
preamp input impedance by 100. Mic preamps have an input impedance
ranging from 1.5k  to 10k ohms, which, when reflected across the
transformer, will range from 150k to 1M ohms. Some vintage guitar
pickups can sound dull and lifeless when driving less than 500k ohms,
rendering the MT-1005 unsuitable for these instruments if the mic
preamp input is below 5k ohms. Adding a FET to the front end would fix
the input impedance at a high value, but at what cost to the
transparent sound of the transformer?<br>
<br>
The best of both worlds was our design decision: the ultimate passive
direct box, and the finest sounding high impedance active direct box.
Adding an active path meant addressing issues such as power supply,
headroom, and sonic degradation, and our decisions are what sets the
Martech MSS-01 apart from the pack.<br>
<br>
Phantom power was an obvious choice for this design. We added large
power reserve capacitors for maximum headroom, and optimized supply
rails providing 40 volts peak to peak for clean operation. The circuit
is similar to that found in high-end condenser microphones, rather than
a standard FET direct box, with a little Martech design magic to
minimize the characteristic ‘tzzzz’ of the FET. Martech went over the
top once again to minimize components in the signal path, basing the
design on how it sounds, not just test equipment measurements.<br>
<br>
The MSS-01 is a unique choice in a vast universe of direct boxes. It
provides a phenomenally transparent interface that allows instruments
to bloom and sound the way they’re supposed to: natural.<br>
<br style="font-weight: bold;">
<span style="font-weight: bold;">Why Use the MSS-01?</span><br>
The unique instrument interface provides a sonically superior passive
path that accommodates both balanced and unbalanced sources, and a
German microphone quality active input to lighten the load on vintage
guitars.<br>
<br style="font-weight: bold;">
<span style="font-weight: bold;">How Does It Sound?</span><br>
Actually the question should be, “How does your instrument sound?” For
that is what the MSS-01 will reveal. The soul intent of the MSS-01 is
to let you hear every nuance from your instrument, without adding any
coloration.<br>
<br style="font-weight: bold;">
<span style="font-weight: bold;">Why Not Always Use the Active Input?</span><br>
This is a subjective issue that only you can decide. Many purists want
a minimal signal path, so they go straight for the Passive Input. It is
recommended that you listen to the instrument on both inputs instead of
assuming which will sound better. The unique circuit for the Active
Input requires a 15 minute ‘warm up’ period, much like tube equipment.
It is important that you apply phantom power and wait for the circuit
to settle before comparing the two inputs. Listen to the Passive Input
during warm up for a reference and then switch to the Active Input.
Listen for excessive dullness or fly away in the top end, keeping in
mind that brighter is not always better. Also listen for depth and
imaging before determining the best loading for the instrument.<br>
<br>
<span style="font-weight: bold;">Why a Balanced Input On a Direct Box?</span><br>
When a typical guitar cable is used the tip/sleeve plug will
automatically unfloat the input of the transformer, making it like most
other DIs, but the MSS-01 can handle the rare occasion when an
instrument has a balanced output. And clever engineers will figure out
all sorts of uses for the 10:1 transformer.<br>
<br style="font-weight: bold;">
<span style="font-weight: bold;">What is Natural Sound?</span><br>
If something sounds “better” than its source, the coloration is called
euphonic, whereas if it sounds worse, we have many esoteric or vulgar
words to describe it. But when it sounds the same, the only word to
describe it is natural. Natural is not sterile or neutral. Sterile
means unable to produce or lacking vitality. If anything, natural sound
is the antithesis of sterility. And natural isn’t just accuracy, for it
moves one into the realm of realism.<br>
<br>
Natural Sound is breathtaking, an aural seduction. Unconstrained
dynamics that never get pinched at high levels. A highly focused image
with low level ambience and room information that doesn’t mysteriously
disappear. Brilliant tonal quality with lots of air. It’s top end that
isn’t smeared, midrange with warmth, and extra octaves of an extended
bottom that is fat and solid. And when punch is required, stand back.
Natural sound is all this and more because nothing is removed.

The <B>Pendulum MDP-1 </B>is a modern two channel vacuum tube Mic/DI preamp designed to be the ultimate way to get your mic or source directly to tape or hard disk. Unlike vintage or hybrid designs, the MDP-1 uses a pure tube, class A high voltage circuit topology with a transformerless output stage to deliver an open, intimate sound with a level of detail that meets the requirements of the most demanding recording applications. Our short signal path design excels in audio performance, delivering extremely wide bandwidth, low noise, and high headroom.
<BR><BR>
A key component of the sound of a tube mic preamp is the input transformer. It's here that we let your select how you would like the preamp to sound. The MDP-1 can be ordered with your choice of two low turns-ratio transformers depending on your requirements: a Jensen 13K7A for a full, open sound with plenty of sparkle in the high end and a deep low end - perfect for recording all sources, especially instrumental music; or a custom-wound transformer for a more 'focused' sound, with extra presence and clarity in the midrange - ideal for a vocal sound that easily distinguishes itself in a mix.
<BR><BR>
The MDP-1 also has all the things you'd expect in a full-featured mic preamp; phantom power, phase reverse, -20dB input pad, a lo cut filter with 10 frequencies and large, illuminated VU meters.
<BR><BR>
The DI signal path is completely transformerless, with a selection of three input load impedances: 10M for piezoelectric acoustic instrument pickups, 1M for magnetic pickups, and 100k with a 20dB pad for line level sources such as keyboards or other -10dBV equipment.
