SAFETY WARNINGS AND GUIDELINES

For best results, please thoroughly read this manual prior to use, paying particular
attention to the warnings in this Safety section:

• Do not expose this device to water or moisture of any kind. Do not place objects
containing liquid on or near this device.

• Do not expose this device to fire or other heat sources. Do not install it on or near
heat sources, such as ventilators, radiators, or near a fireplace. Do not place
objects with open flame, such as lit candles, on or near this device.

• This amplifier should only be used in a well-ventilated area. Do not block any of
ventilation holes on the case. Ensure that there is sufficient airflow over the case
to allow for proper cooling.

• This device contains no user -serviceable parts. Do not open or attempt to modify
this device.

• Do not attempt to defeat the purpose of the ground lug on the power connect by
using a "cheater" plug or by any other means.

• Take care to ensure that the power cord does not get crimped, kinked, pinched,
stepped on, or otherwise damaged. Take care that the cord cannot be a trip/fall
hazard.

• When unplugging connections, always grasp the connector head. Never pull on
the cord or wires.

• Never connect speakers rated for less than 4-ohms to the amplifier in stereo
mode. Never connect a speaker rated for less than 8-ohms to the amplifier in
bridged mono mode.

• Do not bypass the purpose of the fuse by shorting the contacts or by any other
means. If the fuse blows or breaks, replace it with the type specified for your
mains voltage in the Specifications section of this manual.

• Do not connect speakers rated for less than 4 ohms when operating the amplifier
in stereo mode. Do not connect a speaker rated for less than 8 ohms when
operating the amplifier in mono mode. An insufficient load can damage the
amplifier

CONTROLS AND CONNECTIONS

Front Panel

Power Switch: In normal operation, use this push button to power the amplifier on and

off. When the switch is pushed in, power is on. Note that the amplifier can also
be powered on from standby using a 12VDC external trigger or automatically
when an audio signal is detected on one of the inputs, depending on the setting
of the Power Control switch on the rear panel.

Speakers (A and B): Use these push buttons to select which of the two speaker zones

is active. When the button is pushed in, the speaker zone is enabled. When the
button is out, the speaker zone is off. In normal operation, you may use either or
both zones at the same time.

Power Indicator: When there is no power applied to the amplifier, this indicator is off.

When the amplifier is powered on and active, the indicator glows blue. When the
amplifier is powered on, but is in standby more, the indicator glows red.

Balance: Use this knob to fine tune or temporarily adjust the balance between the left

and right channels. This knob should only be used to temporarily adjust balance.
The primary balance should be set using the Master Volume controls on the rear
panel.

Volume: Use this knob to adjust decrease the maximum volume level set using the

Master Volume controls on the rear panel.

Rear Panel

Primary Line: This stereo RCA input is intended for an input that will be normally off or

inactive. Whenever a signal measuring 5mV or more is detected on the inputs,
the amplifier will automatically switch to this input.

Speaker Level Input: If one of your inputs is a speaker level output from another

amplifier, such as in a whole home entertainment system, you can use these
push button speaker grip connectors to connect the speaker wires from the
source. These connectors can accept 20-24 AWG speaker wire.

Primary Line/Secondary Line: This switch determines whether the Speaker Level

input will be considered the Primary Line or Secondary Line input. If both Line
Level and Speaker Level inputs are on the same Line (Primary or Secondary),
the Line Level input will override the Speaker Level input.
