LR-100 Stationary Receiver / Power Amplifier

Preparing the LR-100 For Use

• If you are using the LR-100's power amplifier, make sure
the unit is given sufficient room around the ventilation
holes.
• If you are rack mounting the LR-100, use the optional LA-
326 rack mounting kit. This kit allows for single and dual
rack mounting, and comes with a security cover.
• For mounting on vertical or horizontal surfaces, use the
optional L bracket mounting kit, part number LA-327.
Powering the Unit
1
Please note: if the unit will not power up, please see
Addendum D: Resetting After an Overload Condition.
AC Power Operation
The unit comes with a UL listed inline power supply de-
signed for 115VAC, 60Hz operation. Do not use any other
AC power supply. Use of any non-Listen supplied power
supply will void the warranty. (Battery use is permitted;
see below.) Plug the power supply into the back of the
unit at the connector labeled POWER. Now connect the
power supply to power.
Battery Operation
To operate the unit on a battery or +12VDC power sup-
ply, connect to the rear detachable terminal block as fol-
lows:
i. Pin 3: +12VDC
ii. Pin 4: Ground
Please note that when operating on the +12VDC bat-
tery supply, the POWER switch is bypassed and the unit
is always on.
You can optionally charge batteries by also supplying
power to unit with the batteries connected. In this case,
the batteries are trickle charged at a rate of 18 - 36 mA.
You should only use rechargeable type batteries.
CAUTION: Attempting to charge non-rechargeable bat-
teries may result in explosion and/or fire.

This switch selects what audio is routed to the
OUTPUT audio connectors. The switch has three
positions:
