5.1 Channel Configuration DIP Switch
switches configure each channel's 80Hz 2nd Order Hipass
Filter, Clip Limiter, Amplifier Gain, and Output Mode. In
the example to the right, the DIP switch is set as follows: 6:
80Hz High Pass Filter is Off; 5: Clip Limiter is On; 4&3:
Gain is 1.4V; 2&1: Output Mode is Low Z.
Note: The Gain setting of 1.4V means that a 1.4V input
will drive the amp to full output in any output mode. The other three Gain settings will
apply their respective amplifier gain regardless of output mode, so the actual input
voltage required to fully drive the amp will vary based on the selected output mode.
5.2 Euroblock Input Jack
balanced signal, wire the input signal to the (+) pin, the shield to (G), and wire the (-) input
pin to ground. Euroblock pins are wired in parallel to the 1/4" TRS and XLR combo jack.
5.3 Remote DC Level Control
for remote DC Level Control. The example to the right illustrates a typical DC level control application.
There is no limit to wire length, but do not use any other ground source. If multiple remote DC level
controls are used for different channels, the same ground and V+ sources can be shared.
5.4 Combo Input Jack
wired in parallel to the euroblock input. Do not float the TRS ring or XLR pin 3, connect it to (-)
signal or to ground (if unbalanced).
5.5 Bridge Mode Switch
cent channel pair into bridge mode, combining two amplifier outputs
for more power to a single speaker load. Bridge mode uses only the
odd numbered input channel and level control, disabling the even
numbered input. Speaker outputs for bridge mode must be wired
according to the chart shown to the right. The bridge mode switch
button can be removed for added security by pulling it straight off.

jacks provide safe, secure, and reliable loudspeaker connections,
while preventing outside contact with potential hazardous voltage. See the speaker wiring diagrams to the right (also on the back
panel) for nX amplifier SpeakON
