Features and Specification - SQN-3 Type M
Three identical channels using industry standard XLR-3 type female connectors. Each channel is individually switchable for:
a) 12V T [DIN A-B]
b) dynamic or self-powered microphones
c) 48V phantom
Input attenuation: 0dB, -10dB, or -20dB
Bass Cut: Flat, -6dB or -12dB at 50Hz
Line Attenuation: Adds -50dB before the mic preamp
Mic. Input Sensitivity -70dBu for 0dB (peak level) on the meter with the channel gain at maximum and the Master Gain at 0dB.
Max Level -20dBu (0dBu with 20dB attenuation).
The unit is normally shipped wired to IEC standards, i.e. pin 2 in phase and positive T powering.
Noise Figure -129dBu (A weighted) with 200 Ohm source resistance.
Frequency Response 30Hz to 20kHz +0,-1dB
Line Input L or 3 Dedicated balanced input by way of fourth XLR-3 female connector with side panel fader control
The mic channels 1, 2 & 3 mic, retaining their effective input attenuator
and Bass Cut controls.
Aux. Monitor Input
Balanced input carried on same 5-way D.I.N. connector as line output.
Aux. Input Level Minimum level -19dB; maximum level +11dB.
Microphone Faders Recessed front panel rotary controls. Knobs contoured for ease of adjustment allowing fader position to be judged by touch or viewed from a distance.
Master Fader Front panel rotary control governing all 4 inputs and allowing the level of mix to be adjusted from zero to +3dB (detent at 0dB).
Level Meter Fast response peak reading meter with a log calibrated linear scale; full wave rectification. Nordic Norm and VU versions are available to special order. The meter scale is permanently illuminated by light emitting diodes for low light applications.
Limiter Switchable; operates on the metered output to give approx. 20:1 compression ratio over an 18dB range. Attack time 0.5ms. Release time 100ms.
Line Up Tone 1.1kHz tone operated by a front panel TONE The output level is internally adjustable and is usually set 8dB below peak level.
Line Output 1 Balanced, floating source with a clipping level of + 18dBu, or +20.5dBu into 10k Ohms. The output level is preset so that 0dB (peak level) on the meter corresponds to +8dBu. Distortion at +15dBu is less than 0.1% over the range of 30Hz to 20kHz. The output connector is a standard XLR-3 male type and the output impedance is 160 Ohms.
Line Output 2 Derived from Line Output 1, a second balanced line output is available from a 5-way D.I.N. locking connector which may be switched to Mic. level (-50dBu) by a toggle switch set into the mixer baseplate. Monitoring return on this socket facilitates single cable connection to recorder.
3.5mm Jack Unbalanced output at -40 dBu allows connection of ancillary equipment such as transcription recorder.
Output Monitoring The phones output level is adjustable from zero to 1.5V by a control on the side panel. The connector is a 6.3mm stereo jack, normally wired with tip and ring joined, accepting Gauge A or B connectors.
Monitoring Switches Monitoring is selected by the MXR / AUX switch on the front panel. Choices are:
SQN-3 ground so that external supplies of either polarity may be used. Alternatively, a power supply which does not share a ground with the SQN-3 may be used e.g. a camera battery.
The meter is fitted with a suppressed-zero scale, brought into operation by a front panel push button, which indicates the battery voltage directly.
210mm x 120mm x 44mm.
