Helios

The Rolling Stones had a silver one in their mobile truck, The Beatles had two green ones at Apple Studios and 10cc had a red one at their Strawberry Studios. These are, of course, the legendary Helios mixing desks, an often overlooked and forgotten console having recorded many hit records of the 60s and 70s and designed by the late Dick Swettenham. After Helios Electronics Ltd. closed down in 1979, Tony Arnold of Courthouse Facilities, who had been servicing the consoles, bought the company and started reissuing what's considered the best-sounding of the four different Helios module iterations: the Type 69 microphone preamp/EQ. Repeatedly tested against their surviving vintage modules, these incredibly faithful recreations pass every test thrown their way. The Type 69 mic pre is available through Vintage King alongside an exclusive series of Helios products, including the 1U dual-channel rack and Type 69 500-Series module.

The Helios 1r Stereo Type 69 Mic Pre/Eq is built in an aluminum case and has a glossy black front panel with white silk-screened labeling. The unit is well constructed and neatly wired using all discrete components (no chips). It runs on a 32-volt rail supplied from an internal OEM switching power supply. The mic preamp uses a Sowter Type 8666X input transformer based on the highly desirable Lustraphone (Olympic Sound Studios) transformer model. Input impedance is 1,200 ohms. A separate switchable secondary winding provides for -20 dB of mic attenuation. 
Front panel controls for each channel start on the left side with the mic/line gain switching and a small output-level clip LED. A toggle switch selects between mic, -20dB mic attenuation and the 10k-ohm line input. A seven-position Elma rotary switch doubles as both line input and mic input gain control. There are -5dB and 0dB line gain positions. The five mic gain positions start at 20 dB and go to 70 dB in 10dB steps. Other toggle switches include phase (polarity) flip, EQ cut, mic phantom powering on/off and the ATT switch, where you can engage a small front panel trim pot for a small range of input level adjustment.
The 3-band passive equalizer section uses a combination of RC and LC tone circuits, starting with an RC-based, 10kHz, 6dB-per-octave shelving filter with +/- 10dB range. The LC-based midrange equalizer has a surprising number of frequency choices on a single knob. They are: 0.7, 1, 1.4, 2, 2.8, 3.5, 4.5, 6 and 16 kHz. There is a Peak and Trough toggle switch. (Trough is Brit-speak for cut.) Up to 15 dB of boost/cut is available on the unmarked +/- control. The starting Q for the midrange is a wide three octaves at 700 Hz; then, by 6 kHz, it narrows to two octaves. Q is proportionate: The more boost/cut, the higher the Q.
The LC-based bass section allows up to 15dB boost/cut, and when the control is fully counterclockwise, the bass EQ section is switched out of the signal path. This is good for keeping things ultra-clean. Another rotary Elma switch selects 30, 80, 120, 240 and 400 Hz for the bass peaking section. The same switch rotates to a 6dB-per-octave shelving filter mode that's fixed at 70 Hz with 3, 6, 9, 12 or 15 dB of roll-off. If you like to boost bass and roll-off at the same time, then use the peaking section and select another 12dB-per-octave roll-off filter at 40 or 80 Hz.
The output section is unbalanced and uses an emitter follower circuit and a Philips/BEC electrolytic coupling capacitor, much like what's in the original Helios design. Swettenham found that the engineers at Olympic Studios preferred the sound of this circuit compared to the best output transformers.

The Helios Type 69 Mic Pre/EQ Module Born Again! Re-manufactured classic 3 band eq-pre. Discrete. Switchable lo/mid. Fixed top. Hi-pass. Unlike anything you have ever used (especially if you are stuck in API-Neve land) you will find the Type 69 a unique departure. These hand built units have a Sowter input transformer based on the highly desirable Lustraphone(Olympic) transformer models. The mids are so funky and sweet---- guitars and snare drum's from heaven; woody and sweet! 700 to 2k to die for! Lo's are Pultec-ish. Hi's are sweet and musical. Extremely open Mic-Pre!In mic shootout's, these are as open as the king daddy Telefunken V76m. Transform your life.   The Legendary Helios Electronics Ltd has resurrected with much anticipation and patience, the Olympic Type69 Series EQ as used by the Beatles, Rolling Stones, Bob Marley, Led Zepplin and so on. Helios became known as the musician's choice of recording consoles. Brought in line with modern expectations, these units are built to military specifications with supervision of gear fanatic and music producer Tony Arnold. Endorsed by the late Dick Swettenham, of the original Helios Electronics Ltd, to maintain and service all of the original consoles, Tony later purchased the original company, including all of its circuits and parts. The Olympic Series is a classic 3-band EQ-Pre module, available in a dual mono 1U rack mount or a mono vertical module. The modern circuit is similar to the original, aside from one vast improvement, the build quality and reliability. The openness and clarity has been upheld with the addition of EQ frequency selections. Tony Arnold explains, "We asked many of the original users of the Helios Desks what they felt was missing, and could we make any improvements. Most wanted the 30 Hz added to the Lo-EQ. In order to meet todays CD standards, some wanted a tight high frequency around 16 k, which has been added without changing the original Helios sound whatsoever."
