Avoid impact or heavy vibration to any of the components.

No user serviceable parts inside - refer servicing to qualified service personnel.

Safety

Ensure that the correct mains lead is used with adequate current rating and that the mains voltage is as stated on the unit

Avoid ingress of water or particles into any part of the housing

Do not cover or obstruct cooling vents

Placement

Keep the console out of direct sunlight and away from heat sources.

Do not place heavy objects on top of the control surface

If rack-mounting, use the correct rack-ears and ensure adequate support for the weight of the product.

Allow adequate space for air-flow and keep the console away from damp or dusty environments.

Console layout

The CLP1200 has comprehensive input and output sections which can be split further into various stages of processing and routing. All preamps have studio grade, low noise architecture for the cleanest possible path throughout the signal chain. The input stages are repeated across each channel of the console, which simplifies operation and enables quick and easy location of various controls. The following pages of this manual are divided up into these stages to explain the details and function of each control.

Mic/Line Input Section

Channel inputs and inserts are provided as XLR and/or 6.3mm jack sockets.

The connections for these inputs are assigned as follows.

1.	MIC input	Connect a balanced microphone to this XLRF input. An unbalanced
		microphone can be connected provided that +48V phantom power
		is not used. Wired as follows.
	Balanced		Pin 1 = Ground		Pin 2 = Signal +	Pin 3	= Signal –
	Unbalanced		Pin 1 = Ground		Pin 2 = Signal +	Pin 3	= Ground
2.	LINE input	Connect balanced or unbalanced line level signals to this 6.3mm
		TRS jack input. Wired as follows.
	Balanced		Tip =	Signal +	Ring = Signal –	Sleeve = Ground
	Unbalanced		Tip =	Signal +	-	Sleeve = Ground

3.Channel INSERT The channel signal can be diverted for external processing and

returned back to the channel by connecting a TRS jack to 2 x mono jack lead to this connector.

The channel inserts are post Low Cut but are pre-EQ. Wired as follows.

TRS jack	Tip =	Send	Ring = Return	Sleeve = Ground
Left mono jack	Tip =	Send	-	Sleeve = Ground
Right mono jack	Tip =	Return	-	Sleeve = Ground

4.	+48V Phantom	Press in this switch to apply +48Vdc voltage to the XLR input condenser
		microphones and D.I. boxes which require phantom power
5.	LOW CUT	Press in this switch to apply a 75Hz 18dB/oct low frequency roll-off filter which
		can help to reduce popping, rumble and handling noise from vocal microphones.
6.	GAIN control	This control trims the input signal to the optimum level for the channel strip circuitry.
		Too low a signal level can result in a weak signal-to-noise ratio and too high can result
		in overload and distortion in the signal output.

The adjacent SIG and CLIP LEDs will give an indication of the signal level.

Ideally, the Gain rotary control should be adjusted so that the green SIG LED is lit and the loudest passages of the input signal (e.g. bass drum beats) will just momentarily trigger the CLIP LED. Anything longer than a momentary flicker of the CLIP LED means that the Gain should be reduced. Using the PFL button further down the channel strip gives a more detailed view of the channel level on the main VU LEDs.

Mic/Line EQ Section

7.	HIGH	This control can boost or cut the high frequencies (centre 12kHz)
		by ±15dB (12 o’clock position is zero)
8.	FREQ	This control sweeps the frequency band affected by the MID
		control with centre frequency from 100Hz through to 8kHz
9.	MID	This control can boost or cut the mid frequencies set using the
		FREQ control by ±15dB (12 o’clock position is zero)
10.	LOW	This control can boost or cut the low frequencies (centre 80Hz)
		by ±15dB (12 o’clock position is zero)

Stereo Line Input Section

11.	LINE L/MONO		Connect a balanced or unbalanced line level signal to this 6.3mm
			TRS jack input. Wired as follows.
		Balanced		Tip =	Signal +	Ring = Signal –	Sleeve = Ground
		Unbalanced		Tip =	Signal +	-	Sleeve = Ground
12.	LINE R		For stereo line inputs, use this connector for Right input and the
			above connector for Left input. All following channel controls will
			affect both signals but Left & Right signals will remain separate.
13.	ST1/PC		Switches the channel input between ST1 and the PC interface
			Press this switch in to override the ST1 inputs and the channel
			will be fed from a PC or Mac connected to the USB B connector.
13.	ST2/MPR		Switches the channel input between ST2 and the MPR player.
			Press this switch in to override the ST2 inputs and the channel
			will be fed from playback of USB or SD media via the MPR.
14.	GAIN control		This control trims the mono or stereo input to the optimum level for the channel strip.
			Too low a signal level can result in a weak signal-to-noise ratio and too high can result

in overload and distortion in the signal output.

The SIG and CLIP LEDs above the rotary control give an indication of the signal level. Ideally, the Gain rotary control should be adjusted so that the green SIG LED is lit and the loudest passages of the input signal (e.g. bass drum beats) will just momentarily trigger the CLIP LED. Anything longer than a momentary flicker of the CLIP LED means that the Gain should be reduced.

Using the PFL button further down the channel strip gives a more detailed view of the channel level on the main VU LEDs.
