Hi, selling this SQN-3, tested with batteries and it turns on please see photo. Batteries will not be included for p&p reasons. Comes with cables and case (plastic cover missing from case). Will be posted recorded.
Features and Specification – SQN-3 Type M Series 4000
Microphone
Inputs
Three identical channels using industry standard XLR-3 type female connectors. Each channel is individually switchable for:
Powering:
a) 12V T [DIN A-B]
b) dynamic or self-powered microphones
(150-600 Ohms)
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).
Mic. Polarity
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 1
Dedicated balanced input by way of fourth XLR-3 female connector with side panel fader control.
Line Inputs
2, 3, & 4
The mic channels 1, 2 & 3 may also be switched from mic. to line input mode, 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 VUversions 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 / MIC switch. 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:
Mixer Output
Aux. Monitor Input
Pre Fader signal from CH3 input amplifier
Pre-Fade Listening
Pre-Fade listening is available on CH3. The output of the CH3 Mic. amplifier may be monitored in the headphones even when the fader is closed. This is selected by a third, biased position on the MXR / AUX switch.
Slate Mic
The mixer now incorporates a slate or announcement mic with automatic gain control. The mic is placed behind the front panel between the TONE / MIC switch and the CH2 Fader. It is selected by pressing the TONE / MIC switch to the right. The mic output replaces the main audio. The switch is biased to return to the off position when released. If the monitoring is switched to external, it automatically returns to internal while the slate mic is active.
Batteries
Six AA (UM-3) size cells housed in a quick change compartment. The acceptable range of battery voltages is 5V dc to 18V dc allowing the use of Nickel-Cadmium rechargeable cells, Alkaline-Manganese cells or even Lithium cells. Access is provided to the battery terminals for recharging. A fresh set of Alkaline-Manganese cells will power the unit for more than 12 hours when using dynamic microphones.
External Power
A supply in the range 5V dc to 18V dc may be used. The maximum consumption will be 1.5W and quiescent consumption, without microphones, 700mW. The power input terminals float with respect to the 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.
Battery Test
The meter is fitted with a suppressed-zero scale, brought into operation by a front panel push button, which indicates the battery voltage directly.
Case Size
210mm x 120mm x 44mm.
Construction
The outer case of the mixer is made of aluminium. The end blocks holding the connectors are milled from solid aluminium bar.
All control knobs are special to SQN and are turned and milled from solid aluminium bar. The internal battery compartment is milled and bored from a solid block of polyacetal engineering polymer and the moving parts are aluminium and stainless steel.
All labels and legends on the mixer are permanent. On the end blocks they are engraved; on the front panel they are printed into the hard-anodised surface; on the baseplate they are reverse printed on a polycarbonate label.
The mechanical construction is a development of a system which has proven in the past to be resistant to mechanical damage.
Weight
1.37kg. (1.51kg with batteries).
Temperature Range
The working temperature range is -40C to +70C.
The SQN-3M mixer offers the professional recordist:
Unsurpassed sound quality
Industry standard acceptability
