(2) Boundary EQ
When ON, the amplifier gives a flat response for a natural and
tighter performance. It also removes exaggerated boomy sounds
created by less-than-ideal installation circumstances (i.e. corner
loading, large wall surfaces, installations inside custom cabinetry,
etc.). When OFF, 3dB is added to the response curve. Leave the
Boundary EQ in the OFF position for all other installation or
when the exaggerated boomy sound is designed.
(1) RCA Inputs/Outputs
These terminals have been calibrated to have the same sensi-
tivity level and should both be connected. However, if the signal
comes from the receiver’s/pre-amp’s LFEoutput, connect only
to the R RCA input.
(8) Speaker Outputs
These 5-way binding post speaker terminals accept bare
speaker wire, pin connectors, spade connectors, banana
plugs, and dual banana plugs. The two terminals are inter-
nally connected in parallel all to the same source. They can
be used one at a time or both at the same time as shown in
the next section of this manual. When connecting to both
terminals, a minimum of 4-Ohm load is required for each
terminal.
(3) Crossover
This knob allows the user to set the low pass filter frequency.
Factory set at 80Hz, the low 40 to 60Hz.
(4) 0 - 180° Phase Adjustment
This switch allows the user to synchronize the connected sub-
woofer(s) to obtain better and more precise bass response.
(9) 115V/230V AC Selector
The XJ-700R can operate in a 115V or 230V environment.
Simply slide the selector to the required power setting and
replace the fuse to the proper rating prior to connecting the
amplifier to a power source.
(6) Signal Sensing Modes
This is a 3-way switch. When ON, the amplifier will remain on
regardless of signal presence. When set to AUTO, the amplifier
will only turn on when audio signal is detected. Additionally the
amplifier will go to sleep/stand-by if it does not detect any signal
after about 20 minutes. When set to +12V, use a 1/8” mono mini-
jack to connect a 12V trigger wire from other devices (tip is posi-
tive). The amplifier will turn on/off when triggered (100mA mini-
mum) by the connected device.
(5) DSP ON/OFF
Enable or disable iWoofer™ DSP. When disabled the frequency
adjustment knob (3) will be active.
(10) Main Power Switch
When switched OFF, the amplifier will remain off as there
is no AC power being fed into it. We highly recommend
keeping this switch OFF when the amplifier is not being
used for an extended period of time.
(11) AC Power With Built-in Fuse
This AC line connector is fused to protect the amplifier from
unwanted power surges. Be sure to use the proper fuse
rating when replacing the fuse:
115V~60Hz:ø5x20mm,T8AL/250V
230V~50Hz:ø5x20mm,T4AL/250V
To access the fuse compartment, simply unplug the ampli-
fier from any power source, place a flat-head screw driver in
the small notch and pry it open as
illustrated.
(7) IR Input
Use this 1/8” mono mini-jack to connect to most IR emitter
output connections. The signal will be transferred and inter-
nally flashed to the IR receiver located behind the front
panel.This will eliminate the need to add “stick-on” emitters
in most systems, making it ideal for systems behind closed
cabinet doors or in an equipment rack located in other areas
of the home. Note that this IR connection may not be
compatible with all variations of IR system type. In some
cases, an emitter will be needed to place over the front
panel IR window.
Specifications are subject to change without notice.
