The Rear Panel:
22 - POWER JACK:
Plug the small end of the AC
adapter into this jack. Plug the other end of adapter into
a suitable source of the proper AC voltage, as indicated
on the adapter. Use only the supplied 10VAC, 1400mA
adapter.
23 - POWER SWITCH:
Use this switch to turn the
crossover on and off.
24, 28 - HIGH OUT / MID OUT:
These 1/4” mono
jacks are used as follows:
Stereo mode:
#24 sends the Channel 2 high frequency
signal to the channel 2 high frequency amplifier and
#28 sends the Channel 1 high frequency signal to the
channel 1 high frequency amplifier.
Mono mode:
#24 sends the high frequency signal to the
high frequency amplifier and #28 sends the mid fre-
quency signal to the mid frequency amplifier. (See the
section entitled “For Tri-Amping” on page 11).
25, 29 - LOW OUT:
These 1/4” mono jacks are used as
follows:
Stereo mode:
#25 sends the Channel 2 low frequency
signal to the channel 2 low frequency amplifier and
#29 sends the Channel 1 low frequency signal to the
channel 1 low frequency amplifier.
Mono mode:
#25 is not used. #29 sends the low fre-
quency signal to the low frequency amplifier. (See the
section entitled “For Tri-Amping” on page 11).
26, 30 - 1/4” BALANCED INPUT:
These 1/4” TRS jacks
are used as follows:
Stereo mode:
#26 feeds the channel 2 input signal into
the crossover’s Channel 2 and #30 feeds the channel 1
input signal into the crossover’s Channel 1.
Mono mode:
#26 is not used. #30 feeds the input signal
into the crossover.
(Use the 1/4” jacks for shorter cable runs, or when XLR
connectors are unavailable.)
27, 31 - XLR BALANCED INPUT:
These 3-pin XLR jacks
are used as follows:
Stereo mode:
#27 feeds the channel 2 input signal into
the crossover’s Channel 2 and #31 feeds the channel 1
input signal into the crossover’s Channel 1.
Mono mode:
#27 is not used. #31 feeds the input signal
into the crossover.
(Use the XLR jacks for long cable runs, or when 1/4”
connectors are unavailable.)
