Starting with serial number 35000, the layout was revised to bring the CHANNEL ATTENUATORS onto the front panel and the Mic Power Selectors and Mic/Line attenuators were changed from rotary to slide switches. 12V Phantom powering was dropped.

HISTORY The SQN-3 was conceived as a 4-channel mono mixer for Kudelski's Nagra SNN tape recorder by the design team which produced the original SQN-1 Control Unit for the SN in 1973. The SQN-3 intended for SN use was designated Type C (for Control Unit) and first appeared in June 1980. At the same time a mixer without SN controls - the Type M - was released for users of 1/4 inch Nagras and other recorders, since no portable mixer with the facilities and performance of the SQN-3 had previously been available. These models had a serial number commencing 1000 (SERIES 1000) and the SQN-3C continued unchanged until it was discontinued in September 1988.
In September 1981 the SQN-3 Type M was considerably modified to meet the growing needs of broadcast video users. This model (known as the SERIES 2000) with Serial Numbers commencing 2000 or 20000 remained in continuous production for exactly ten years with only small modifications in the light of continuing development.
The SERIES 3000 with Serial Numbers from 31000 was introduced in September 1991 and differed from the Series 2000 only in that the side connector panel was re-modelled to provide for a Cannon XLR-3 male output, with an unbalanced output available from a 3.5mm jack socket and the same 4-way Hirose powering / charging socket as our other mixers. At the same time the output mic / line level switch was moved to the baseplate and provision was made for Channel 3 to be switched to accept line inputs in situations where two had to be accommodated.
The SERIES 3000 (version II) with Serial Numbers from 34000 was introduced in January 2001. The internal electronics of this version were totally revised with the addition of extra functions while the mechanical construction remained the same and only the front panel appeared different. The limiter circuit was changed to be similar to that used in the current stereo SQN mixers. The meters were illuminated by light emitting diodes, giving a brighter light than the original glow tubes.
The added functions are:
- A slating mic with automatic gain control, activated by an extra position on the TONE switch.
- Pre-Fade Listening to Channel 3, activated by an extra position on the
Phones MXR / AUX switch. - A new limiter circuit, modelled on that fitted to the SQN IVe.
- From Serial No. 34200, all three Mic Channels could be switched to Line.
The SERIES 4000 (version III) with Serial Numbers from 35000 was introduced in June 2002. The modifications are:
- The channel attenuators have been moved to the front panel, making them more readily accessible.
- The rotary MIC POWERING selectors on the base have been replaced by slide switches. The 12V Phantom setting has been dropped.
- The MIC / LINE attenuator function, which was previously incorporated with the MIC POWERING has ben separated out onto a second slide switch per channel.
