Bridging channels. 

Two channels can generate a capacity of around 100W to a loudspeaker of 
8 ohm. The switch (2) must be adjusted to the ‘bridge’ setting to do this. 
The loudspeaker is then connected to the 2 red clamps on the loudspeaker 
connection. The odd-numbered line input of the channels in question is then 
used for the signal input. For example, if channels 1 and 2 are used in the 
‘bridge’ setting, signal input 1 is used. Only the jumpers for the odd-
numbered inputs are used. 

 

Overview of connections: 

 
 

1:

 

Loudspeaker connection. 

2: Bridge 

switch. 

3: Volume 

setting. 

4: 

Routing setting (jumpers). 

5: 

Common line inputs. 

6: 

Individual line input. 

7: 

Line outputs (looped through to other amplifier). 

8: AC 

connection. 

See Fig. 1 

 

5. Examples of installations: 

A single source for all zones: 

single source can be heard in all 6 zones. Each zone has its own volume 
control. All jumpers are positioned on L /R. The common input is used as 
input (L/R).

Up to 6 stereo channel zones can be additionally amplified. In the example 
above, 4 extra zones have been amplified. The jumpers for the channels 
used are positioned on ‘IN’. 

See Fig. 3
