REAR PANEL DESCRIPTION
1. LEFT HIGH PASS BALANCED OUTPUT- This XLR male connector provides a
balanced high pass output from the left channel input. The high pass frequency
is set at 100 Hz with a 24 dB per octave roll off.
2. RIGHT HIGH PASS BALANCED OUTPUT- This XLR male connector provides
a balanced high pass output from the right channel input. The high pass
frequency is set at 100 Hz with a 24 dB per octave roll off.
3. LEFT FULL RANGE BALANCED OUTPUT- This XLR male connector provides
a
balanced full range output from the left channel input. This connector may be
used to daisy-chain the full range signal to additional powered sub cabinets
such as another SA118 or SA115.
4. RIGHT FULL RANGE BALANCED OUTPUT-- This XLR male connector
provides a balanced full range output from the right channel input. This
connector may be used to daisy-chain the full range signal to additional
powered sub cabinets such as another SA 118 or SA115.
5. INPUT PHASE SWITCH- This switch is used to change the polarity of the input
signal going to the power amp of the subwoofer. This will be dependent on the
placement of the Tripower relative to the subwoofer or if another type of
powered cabinet is to be used. The (0) setting (switch out) will make the
subwoofer phase coherent with any of the Tripower series. This switch will not
change the phase of any of the balanced outputs.
6. INPUT SENSITIVITY- This control determines the overall input level of the
signal to the power amp section of the subwoofer cabinet. Adjusting this level
will not affect the level of the signal passing through to the full range or the high
pass outputs.
7. LEFT BALANCED INPUT- This female XLR connector provides an input for the
left channel signal source. This will also feed the left channel signal to the left
high pass and left full range balanced outputs.
8. RIGHT BALANCED INPUT- This female XLR connector provides an input for
the right channel signal source. This will also feed the right channel signal to
the left high pass and right full range balanced outputs.
9. EXTENTION SPEAKER OUTPUT- This Speakon connector provides an output
for a passive extension speaker such as the SP118 or SP115. This will also
increase the power output of the subwoofer amplifier from 600 watts to 900
watts. If another cabinet is to be used other than a SP118 or SP115 as an
extension cabinet, make sure the load of the extension speaker is not less than
4 ohms.
10. POWER SWITCH- This switch provides power to the subwoofer amp section.
Make sure that the input sensitivity control is set to minimum upon power up
11. POWER INLET MODULE- This module provides a connection for the power
cord and also houses the mains fuse.
