Mixing Consoles - Input Channels
S2-CML Mic/Line Channel
The mic/line input channel is a mono input with a button switch to select either Mic or Mono Line.
For the Mic input, phantom power at +48V can be configured. The Mic input has a jumper selectable high pass filter to remove low frequency rumbles. If the Mic input is used for the presenter’s mic it can also become the talkback mic. The talkback function will be retained when the channel input is switched to Line.
Equalisation is fitted as standard on this channel and is enabled by the EQ button, providing 10dB cut and boost at HF (6.5kHz) and LF (100Hz). A balanced line level insert send and return is available for the Mic input for the insertion of an effects, or voice, processor into the mic channel. The send and return is disabled in Line mode.
There are logic remote input controls for Mic Cough muting and Reverse Talkback. There are output controls for Mic Cue lights and separate line remote start/stop controls by fader or ON button. Both latching and momentary contacts are catered for.
The remote outputs on the 9 way D-type plug are fed from NPN opto-isolators.
The Mic input provides a jumper selectable output to facilitate either Control Room speaker or Studio speaker muting and the channel can also be used to control either one of two separate timer displays.
In addition the Line input can be configured with all the features of the Mic input when used as a Mic input with an external microphone amplifier, e.g. for monitor muting purposes.Gold plated Neutrik XLR connectors are used for the audio inputs and outputs.
