• The SQN-4S mixer includes all of the essential advances of its ancestor: all-electronic input amplifiers, large output transformers for low distortion bass, virtually unbreakable analogue level meters, pre-fade listening, slating microphone, logic processing of many switching functions leading to a minimal length audio path and optional feed for four output channels
• Further advances of the SQN-4S include the new limiter, separate switching of the pre-fade listening, a low distortion tone oscillator and more convenient handling of high output powered microphones.

 

Features and Specification – SQN-4S Series IV
Mixer Inputs Four transformerless balanced inputs using XLR-3 type female connectors. Channels one and two also share an XLR-5 type connector. Each channel is switchable for:

  1. Powering:
    • a)12V T (Din AB)
    • b)12V Phantom
    • c) 48V Phantom
    • d) Dynamic (150 to 600 Ohms)
  2. Attenuation:
    • 0dB, -12dB or -24dB
  3. Bass Cut:
    • Flat, -4dB or -10dB at 100Hz
  4. Line Attenuation:
    • Adds 50dB attenuation before the mic preamp.
Sensitivity -78dBu for nominal line level (PPM4, 0VU) with the channel gain at maximum and the master gain at 0dB
Max Level, Mic Inputs -20dBu (+4dBu with 24dB attenuation)
Noise Figure -130dBu (A weighted) from a 200 Ohm source.
Frequency Response 20Hz to 20kHz +0, -1dB, referred to 1kHz.
Crosstalk Isolation, channel to unrelated channel: 75dB at 1kHz, 60dB at 15kHz.
Channel Configuration
[GANG]
[MAT]
The mixer is intended to work in several modes. The mode controls affect channel pairs CH1 & 2 and CH3 & 4. Within the pairs, channels 1 & 3 are called “first channels” and 2 & 4 “second channels”.

  1. Twin MONO [O] in which the channels are unganged and each input channel can be routed or panpotted to either or both of the output channels.
  2. Stereo [S] ganging in which the first channel fader controls the gain of both channels and the first channel panpot acts as a stereo balance control
  3. Mid-Side [MS] ganging in which the first channel fader controls the gain of both channels and the second channel fader acts as an image width control.
  4. Mid-Side Matrix [MAT] matrixing in which each channel pair has a mid-side matrix which will convert an MS input into AB stereo or vice-versa.
  5. Panning Mode [PAN]. The CH3, CH4 pair has a selectable panning mode in which the output is treated as MS encoded stereo and the channel signal is panned to move across the equivalent AB stereo image.
