Master Routing Section 

 

50.

 

FX SEND   

Overall level control of signals routed to the FX Send buss, either  

for internal DSP or FX Send output (37). When using the internal 

DSP, it is important to observe the LED level meter on the DSP 

section (56) and if the signal is clipping (red LED lighting) to 

reduce the FX SEND level accordingly. 

 

51.

 

AUX SEND 

Overall level control of signals routed to the AUX Send output (37) 

 

52.

 

2-TK/PC   

Output level control for the 2 track RCA inputs (35) or stereo  

input from the PC interface (34) 

 

53.

 

2-TK/PC MODE

  When not pressed in, the main output is routed digitally to  

REC/PLAY  

the PC interface for recording to PC or Mac computer.  
Pressing this button reverses this by routing the output of  
the PC or Mac back to the PC interface for playback. 

 

54.

 

2-TK/PC ROUTE  Normally, playback from the PC interface is routed via ST1 channel. 

ST1 - L/R  

Press this button in to route playback directly to main outputs via 2TK/PC control (52) 

 

55.

 

PHONES LEVEL  Level control for headphones output. 

 

 

DSP Effects Engine 

 

The CL1200 has an internal 24-bit DSP processor for audio effects, as detailed on the DSP Table (next page) 

 

56.

 

6-segment LED input level meter. Indicates overall input level to DSP. 

 

57.

 

LED numerical display. Indicates selected program (see table below) 

 

58.

 

TAP   Press once to switch the rotary control (59) to PARAMETER 2. 

Tap rhythmically more than twice to set a tempo for time effects 

 

59.  PROGRAM/PARAMETER  Turn this rotary encoder to select a program. 

 

The numerical display will flash the selected program number.  

 

Press the encoder to confirm the selection and the display will stop 

flashing and the selected program will be active. 

 

 

Press the encoder again and a dot will appear in the display indicating 

PARAMETER 1. Turning the encoder will change PARAMETER 1 for the selected program as detailed in the 

DSP Table on the next page. 

 

 

Pressing the TAP button (58) will switch to PARAMETER 2 and then turning the encoder will change 
PARAMETER 2 for the selected program. These parameter changes are stored for when the program is 

selected in future. 

 

60.

 

EFF TO MAIN L/R Press this button to send the output of the DSP to the main L + R via the FX fader (64) 

 

61.

 

EFF TO MON 

Press this button to send the output of the DSP to MON1 & MON2 via the FX fader (64)
