Architecture & Engineering Specifications
The audio mixing console shall be an analogue design suitable for use in live performance and studio recording, and equipped with 12 MIDAS microphone preamplifiers.
The mixing console shall have 12 mono channels, and each shall provide the following: 1 balanced XLR microphone input, 1 balanced ¼ " TRS line level input, and a ¼ " TRS Insert. A gain control shall provide adjustment of the input signal from 10 to 60 dB (mic) and -10 to +40 dB (line). An EQ treble control shall provide a range of 15 dB of boost and cut of shelving EQ at 12 kHz. An EQ mid control shall provide a range of 15 dB of boost and cut, and a mid-sweep control shall provide peak EQ adjustment from 150 Hz to 3.5 kHz. An EQ bass control shall provide a range of 15 dB of boost and cut of shelving EQ at 80 Hz. Aux 1 and Aux 2 controls shall provide adjustment of the Auxiliary 1 and 2 outputs from 0 to +10 dB. A pan control shall position the mono channel in the mix.
A PFL (pre fader listen) switch shall allow the channel signal to be soloed and routed to the master meters, monitors, and headphones. A mute switch shall be provided to mute the channel, and a peak LED shall indicate channel signal overloading. A 60 mm mono channel fader shall allow adjustment of the channel level in the mix.
The mixing console shall have 2 stereo channels, and each shall provide the following: 2 balanced ¼ " TRS line level inputs. A stereo gain control shall provide adjustment of the input signal from -20 to +20 dB. An EQ treble control shall provide a range of 15 dB of boost and cut of shelving EQ at 12 kHz. An EQ bass control shall provide a range of 15 dB of boost and cut of shelving EQ at 80 Hz. Aux 1 and Aux 2 controls shall offer adjustment of the Auxiliary 1 and 2 outputs from 0 to +10 dB. A balance control shall position the stereo channels in the mix. A PFL (pre fader listen) switch shall allow the channel signal to be soloed and routed to the master meters, monitors, and headphones. A mute switch shall be provided to mute the channel, and a peak LED shall indicate channel signal overloading. A 60 mm stereo channel fader shall allow adjustment of the channel levels in the mix.
The mixing console shall be provided with 2 balanced ¼ " TRS Auxiliary outputs. Each mono and stereo channel shall have an Aux 1 and Aux 2 level control. Each Aux output shall be provided with a pre-fader/post-fader switch.
The mixing console shall be provided with 2 balanced ¼ " TRS monitor outputs. Level adjustment shall be provided with a local level control. The output shall be a copy of the main mix, or the pre-fader output from any soloed channels (channel PFL switch engaged), or the 2 track input. The mixing console shall be provided with 2 unbalanced RCA line level inputs, and 2 switches shall allow the input signals to be routed to the main mix, or to the monitor outputs. There shall be 2 unbalanced RCA line level outputs to allow the main mix to be recorded.
The mixing console shall be provided with 1 stereo ¼ " TRS output for headphone monitoring of the main mix, or soloed channels (channel PFL switch engaged). Level adjustment shall be provided by a Phones level control.
The mixing console shall be provided with 2 balanced XLR outputs to send out the final left/right mix to external amplifiers and equipment. Adjustment of the final mix output shall be provided by 2x 60 mm master faders. 2 ¼ " TRS main out insert jacks shall be provided.
Global 48 Volt phantom power shall be provided to each microphone input via a phantom power switch. A +48V LED shall indicate when phantom power is activated.
2 LED ladders shall indicate the levels of the main mix, or soloed channels (channel PFL switch engaged). An LED will indicate when the mixer is powered on, and a PFL LED will indicate when the meters are monitoring soloed channels.
The mixing console shall be provided with an internal switch mode power supply, capable of operation at AC voltages ranging from 100 to 240 VAC, at 50/60 Hz. The mains connection shall be a standard IEC receptacle.
The mixing console dimensions shall be 95 mm high x 438 mm wide x 370 mm deep (3.7 x 17.2 x 14.6"). The nominal weight shall be 5 kg (2.3 lbs).
The mixing console shall be the MIDAS DM16. No other mixing console shall be acceptable unless submitted data from an independent test laboratory verifies that the above combined performance / size specifications are equalled or exceeded.
