Designed and built by former career studio bassists, the A Designs Audio REDDI has been hailed by engineers and bassists alike as the best-sounding DI around. Inspired by the glorious sound of the Ampeg B-15 tube bass amp, its 6N1-P tube-driven amplifier feeds signal directly into a hefty custom output transformer, which is key to providing a harmonically rich tone. Its wide-bandwidth design from 20Hz to 60kHz reduces in-band phase shift, which results in greater detail and realism in the audible spectrum. Another big plus of its wide-bandwidth design is the prevention of LF phase shifts by maintaining a linear response extending below the audible bass range, which is the secret to achieving a big, full sound.Complimenting its distinctive bright red steel chassis, the A-Designs Audio REDDI has a front-panel Neutrik XLR/1/4″ combo input jack, balanced XLR output, and a 1/4″ thru-put, for those who desire the reassurance of sending signal to a bass amp (before they wind up discarding the miked track and go with the REDDI track alone). There is also a 0-16dB-gain control on the front panel as well. Take note, the REDDI is not a high-gain device. Gain has been carefully designed and controlled in order to avoid the slightest compromise to sound quality. Finishing up the front panel is an extremely bright blue LED power indicator. The exceptional brightness of the LED was intentionally provided for easy visual confirmation that the REDDI is powered on, and also to temporarily blind annoying A&R reps lingering in the control room. On the back panel are toggle switches for power and ground lift, along with the REDDI’s IEC power connector.Not just for bass, the REDDI’s all-tube circuitry can enhance the character of any instrument run through it; with an airy top end to go with the full, rich mids and bass it also imparts. That’s why Grammy-winning producer Ted Perlman (Chicago, Bob Dylan, Burt Bacharach, Elton John) runs all his guitars through the REDDI. And as long as we’re on the subject, the ever-increasing list of world-class bassists and engineers who rely on the REDDI includes notable bass players, such as Reggie Hamilton, Justin Meldal-Johnsen, Viktor Krauss, Jamiroquai’s Paul Turner, Steve Bailey, Don Boyette, Carlitos del Puerto, and Millard Powers of Counting Crows; along with producer-engineers such as Tony Sheppard, Dylan Dresdow, Ross Hogarth, Billy Bush, Ronan Chris Murphy, and Russ Long.
Features:
First stage gain is set from +6 to +63 dB by a 12 position Grayhill switch. Another 20dB of gain is available after the output level potentiometer. Polarity reversal and high pass switches on the two channels are complimented by operating and overload LED metering.
The tone of the 212L mic preamp finds its roots in the classic API 2488 series all discrete recording consoles, best known for the famed "LA" sound. This same mic preamp design is packaged into a compact module with features like a continuously adjustable Gain control and a unique 5 segment LED VU meter on each panel.
An audio chain is only as strong as its weakest link. Often, emphasis is placed on obtaining the highest quality microphones, while neglecting the integrity of the mic preamp. The API 212L microphone pre-amplifier is an integral part of the famous Legacy Series Console and is now available for the L200 Rack System. This modular unit incorporates the same circuit as the legendary API 512b, thus preserving its sonic qualities. This mic-pre articulates high frequencies with great detail, while delivering the big sounding, warm bottom end that API is famous for. Whether it's a live performance or the private setting of a studio session, the 212L will capture every nuance of the moment.
The 212L mic-pre all discrete circuitry features the API 2520 op-amp, the RE 115 K input and the AP-2623 output transformer. A -20 dB pad is provided, allowing the level feeding the mic transformer to be reduced by 20 dB, while keeping the proper load on both the mic and transformer. 48V Phantom power can be locally switched on or off via the front panel switch. An LED VU meter provides a true VU indication of the mic pre output level. The low noise floor, together with a clip point over +28 dBm, makes this preamp suitable for the most extreme applications requiring the highest quality audio.
The 212L Microphone Preamplifier makes use of the 2520 op-amp and therefore exhibits the reliability, long life and uniformity which are characteristic of API products.

What makes the API 512C unique is its long evolution from the original 1967 era 512, the first modular mic pre, to the current full featured 512C, while preserving the original sound character that made it so much a part of the early days of recording. Offering high headroom and a wide variety of inputs and input access ponts, it is ideal for unusual and demanding applications.
Imagine a situation where only a few preamps are needed, yet the smallest available console has a proportonally "small" mic preamp, making it useless for the demanding application, or conversely, imagine where you need a large number of preamps, and a console of sufficient inputs and quality would be too large to transport or rack mount. The 512C hits the spot with its quality and famous tone. Expand, combine or downsize at any time without trade-ins or product obsolescence. In addition, the 512C's sound and performance exceeds most "console mic pres" in every respect.
The beauty of the entire API 500 Series is its long term flexibility and lasting value when needs change over time. With a range of mounting frame options, the 512C will be a valuable asset to your performance critical applications.
The 512C Mic/Line Preamp makes use of the 2510 and 2520 op-amps and therefore exhibits the reliability, long life, and uniformity which are characteristic of API products. Features
The A2D analog section consists of the circuitry contained in two API 312 mic preamps, or one half of the popular 3124 quad mic preamp rack product. A level control pot with an expanded 20-segment metering system shows precise mic gain levels. Control switches include polarity, 48v phantom power, input pad, 2:1 transformer routing, and Mic/Line select. Each analog input contains a balanced low-level XLR connector and a high-level line input on a 1/4 inch jack.
The Digital section of the A2D includes two level pots to adjust the feed to the A/D converters, each with a corresponding 20-segment calibrated meter. A multi-position switch selects the desired sample frequency. The External Sync LED will light when an external clock signal is used.
Rear panel Analog connectors include an XLR input and output for each channel, as well as a balanced 1/4" TRS insert to the A/D converter. This allows the A2D to have external analog processing devices inserted in the audio chain (EQ, compression, etc.)
Digital interface connectors provided are SPDIF single ended RCA connector and AES digital out on XLR. A coaxial BNC accepts external "Super Clock" which will illuminate the front panel EXT SYNC LED when locked.
In addition, there are a pair of 9-pin D-sub connectors which allow the linking of multiple A2D units, all operating off the first sample-rate clock in the chain.
The design uses an 8 transistor discrete Class A front end with extended band-width and a noise floor close to the theoretical Johnson limit. Carefully chosen close tolerance components are used to achieve high CMRR at all gain settings and distortion is minimised to less than 0.001% at 20dB gain and +10dBu output. This outstanding technical performance delivers a mic amp with incredible transparency and detail without colouration or other unwanted artefacts.
Each Mic amp also features switchable input impedance, allowing the user to explore the subtle variations in microphone character that are determined by output termination.
All channels include an XLR input, ?soft start? 48V phantom power, switchable input impedance, 25-250Hz hi-pass filter as well as line input selection. Channels 1 and 2 also feature a -20dB attenuator and a high-impedance Instrument/DI input on a front panel mounted jack. LEDs provide indication of signal present and overload.
Two digital output option cards are available - one with ADAT optical interface, the other with AES/EBU and ADAT.
The BAE (formerly Brent Averill Enterprises) 312A mic preamps, made using the new Avedis 1122™ opamps, are punchy, have great bass and have a clear, extended top end. The sound is in your face and they don't compress transients. The low end is tight with good attack. They are excellent for drums and percussion. These pres are very cost effective. Many people buy racks of 6 or 11 to cover the entire drum kit. Features:
