The two-channel model SX-27000 and SX-29000 has control options for the Input sensitivity and the signal input
mode of the XLR input sockets CHA and CHB.
Sensitivity Switches:
Select between four different input sensitivity level with the two dip
switches 1 and 2. (0,775V/1,0V/1,5V/2V)
Figure 7.1 shows how to select the right setting.
The right setting and a correct system gain structure is very important to reach maximum signal headroom, less
noise and avoid clipping at any position of your sound structure. Please refer to 9.7 Setting System Gain Structure.
Input Mode:
Select between Stereo or Mode Bridge Mode as shown in figure 7.1.
If the dip switch 3 are set to Mono Bridge Mode the signal of the input socket CHA will be internal linked to the
Input signal for CHB.
Clip:
Select if the internal Clip protection limiter should be on or off as sown in figure 7.1.
If the dip switch 4 is set to Clip the internal clip protection limiter is on.
7.) CONTROLS AND INDICATORS
Figure 7.1
Switch the two amplifier channels A/B to Mono Bridge Mode. The input
signal of CHA will be linked internal to CHB.
If use the output sockets A and A+B with 1+/1- connection the two rela-
ted output channels will have the same signal of input CHA. If use output
socket A+B with 1+/2- connection the amplifier will work in mono bridge
mode. Output socket A can not be used if you want to drive the two amp
channels in bridge mode!
Select the input sensitivity (Volatage Gain)
Switch on/off the internal clip protection limiter.
