in a built-in installation such as a bookcase or cabinet that may impede the flow of air
through the ventilation openings.

radiators, heat registers, stoves, or other subwoofers or components that produce heat.
10. Power Sources – The subwoofer should be connected to a power supply only of the type
described in the operating instructions or as marked on the subwoofer itself.
11. Power Cord Protection – Power supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon them or against them, paying
particular attention to cords at plugs, convenience receptacles, and the point at which
they exit from the subwoofer.

when:
a. The power supply cord or plug has been damaged.
b. Objects have fallen or liquid spilled into the subwoofer.
c. The subwoofer has been exposed to rain.
d. The subwoofer does not appear to operate normally or exhibits a marked
change in performance.
e. The subwoofer has been dropped or damaged.
17. Servicing – The user should not try to service the subwoofer beyond what is described in
the operating instructions.
18. Overloading – Do not overload wall outlets, extension cords, or integral convenience
receptacles as this can result in a risk of fire or electrical shock.
19. Replacement Parts – When replacement parts are required, be sure the service techn cian has used replacement parts specified by the manufacturer or have the same charac teristics as the original part. Unauthorized substitutions may result in fire, electric shock,
or other hazards.

1 - Power LED - Indicates the power state, no color - off, red - standby mode, blue - on.
2 - Master Volume - Controls the overall volume of the sats and subs together.
3 - Sub Volume - Used to set the relative level of the subwoofer volume to the sat volumes.
At MAX there is about +12dB more gain available over the sat levels, but this will vary
based on the efficiency of the sats and subs used.
4 - Sub Crossover - set the crossover point for the subwoofer between 40Hz and 150Hz. 80Hz
is marked as a reference.
5 - Sat Crossover - sets the crossover point for the sats. Turned all the way to the left, there is
a switch position which defeats the crossover and runs the sats full range. Once the control is rotated towards the 40Hz position, the crossover will be switched in and provides a
range of 40Hz to 150Hz. 80Hz is marked as a reference.
6 - 45Hz Boost switch - allows the addition of +4dB of bass boost for the subwoofer.
7 - Phase switch - switches the polarity of the subwoofer to allow better matching to the
sats in certain situations - the setting depends on the specific installation and James
recommends you start in the 0 degree setting.
8 - Rack ears - for rack mounting the amplifier - these can be removed if needed for shelf
mounting.
9 - Right sat speaker connection. Connect the red terminal to the positive on the right sat
speaker.
10 - Left sat speaker connection. Connect the red terminal to the positive on the left sat
speaker.
11 - Sub woofer speaker connection. Connect the red terminal to the positive on the subwoof-
er.
12 - 3 position Power switch - “OFF “turns the amplifier completely off, “AUTO” position for
signal sense on/off, and “ON” leaves the amp permanently on.
13 - Left/Right RCA inputs. A 1/8 miniphone to RCA cable is included for cellphone and tablet
sources.
14 - 120V/240V selector - make sure this is correctly set for your AC line voltage.
15 - IEC Power connection.
