SoundCraft 1601S manual Input Selector Switches, Clip Indicators, PRE-TRIM Pads

CHANNELS 1 & 2 (Channel 1 of 1601S Shown)

This section of the mixer features all the main controls for input channels 1 & 2, most of which come under the control of the digital signal processor (DSP). The EQ section in both channels are created within the DSP which enables the mixer to deliver an amazing -85dB of cut whilst, for professional considerations, limiting the boost to just +6dB. The level faders are also digitally controlled which assures extra-long life for these hard-working components.

INPUT SELECTOR SWITCHES

These 2-way selector switches select the connected playback device for each channel. They allow you to select between the CD/ LINE inputs and the PHONO inputs.

CLIP INDICATORS

The [CLIP] indicators are used to detect overload conditions in the gain section before the A/D convertors. When the signal level becomes too high for the A/D convertor the indicator will illuminate and the audio sound will become distorted.

If this occurs, back-off the [TRIM] control until the [CLIP] indicator is not illuminated.

PRE-TRIM PADS

These attenuator controls are situated under the top panel fascia (channel 1 on the left side / channel 2 on the right side). They can be used to attenuate the input signal level prior to the main [TRIM] control to avoid overload conditions. These controls are factory set to maximum gain for professional use.
