This indicates the 

Send Input

 level, or the level of audio sent to callers 

when 

On Air

. This indicator should be green during typical audio. It will 

light amber when the system is approaching its limit and red when the 
system is clipping.

This indicates the incoming level of the call(s) on Hybrid 1. This indicator 
should be green during typical audio. It will light amber when the system is 
approaching its limit and red when the system is clipping.

This indicates the incoming level of the call(s) on Hybrid 2. This indicator 
should be green during typical audio. It will light amber when the system is 
approaching its limit and red when the system is clipping.

Use this control to adjust the audio level sent to the caller. The 

Input Indi-

cator 

(1) should be used to make this adjustment.

Use this control to adjust the audio sent to the callers when they are 

On 

Hold. 

This adjustment should be made with program audio being sent into 

the 

Hold Audio 

input. To make the adjustment, place a call into the system 

(using an external telephone) and put the call 

On Hold

. Adjust this level 

for a good sounding signal on the telephone.

Use this control to match the 

Aux Out

 level to that of your console or re-

corder. 

Use this control to match the 

Hybrid 1 Out

 level to match that of your 

console or recorder. Note this adjusts level of the output stage only (i.e. 
this does not boost the caller level into the hybrid).

Use this control to match the 

Hybrid 2 Out 

level to match that of your 

console or recorder. Note this adjusts level of the output stage only (i.e. 
this does not boost the caller level into the hybrid).
