SR SERIES REAR PANEL
SR900 REAR PANEL
SR1500 - SR2000 REAR PANEL
1. MAINS POWER FUSE; only replace with the same type and rating specified on the rear panel.
2. MAINS POWER INLET SOCKET; connect the mains cord here before connecting to the power source.
(Either IEC or NEUTRIK POWERCON)
3 & 4. CH1 & CH2 SPEAKON OUTPUTS; use these output sockets to connect the speaker cabinets.
Stereo mode: 1+ connects to the positive port, 1- connects to the negative port.
5 & 6. CHANNEL 1 & 2 BINDING POST OUTPUTS; binding post speaker outputs are provided for each
channel and the speaker cables can be terminated with banana plugs or stripped wires. The red binding posts are
the signal outputs from each channel and the black posts are the chassis ground. Connect the red posts to the
positive inputs of the associated speakers. For Bridge mode operation, only the red binding posts are used and the
associated speaker load is connected between the two red posts.
Which ever connections are used, the parallel speaker load should be limited to a minimum of
4 Ohms per channel or 8 Ohms in bridge mode for any application.
7. REAR AIR EXHAUST; the air flow for cooling on this amplifier flows from front to back, allow sufficient
clearance when rack mounting the unit.
8. SERIAL NUMBER LABEL; contains the serial number of the amplifier.
9. INPUT SENSITIVITY SWITCH; this switch changes the input sensitivity of the amplifier when using low
or high nominal input signals. Most professional mixing consoles operate at a nominal level of +4dBu; therefore use
the 26dB position to provide plenty of fader movement. For a disco mixer operating at a nominal level of 0dBu or
less use the higher gain position.
10. 30Hz HI-PASS; toggles the hi-pass filter ON/OFF. In the ON position this filter will cut extremely low sub-
sonic frequencies, protecting the speakers from over-excursion
