INTRODUCTION

PLA305 5-Channel Power Amplifier

Designed to mount directly into the cutout provided on one of our 110 series
subwoofers,the PLA305 is a powerful and versatile center of your multi-channel
sound reinforcement system. The 5 amplifiers (100 watts for the sub, 50 watts
each for the 4 full-range outputs) use ProBASH technology for great sound and
superb efficiency. ProBASH circuits track the audio waveform and provide a
dynamic DC voltage,on demand, to the class AB amplification stages. An auto-power
feature switches power on or off in response to the audio signal.

{

PLC4.1 Controller

Mounted directly to PLA305 amplifier the PLC4.1 Controller is the control center,
for audio signal pre-amplification, balancing, distribution and filtering. For a full
description of its flexibility and use see the PRODUCT section of this manual.,
Master remote volume control is possible with our remote control options (see the
REMOTE section of this manual). Individual channel remote volume control is
enabled with the installation of our VCA card (see your Tannoy dealer).

PLM-4 Mixer with Ducking

The PLM-4 has all the inputs needed for most commercial applications. It is
designed to provide a properly mixed and pre-amplified balanced audio feed to
the PLC4.1 Controller via a long-wire run. Power supply is by a 12V DC wall-wart.
For a complete description of its controls and functions, see the PRODUCT section
of this manual.

REMOTE VOLUME CONTROL

NOTE: Overall master volume control is a standard function of the PLC4.1. Remote control of
individual channels requires the factory installed VCA card.

1) Wall-mount Potentiometer (25K ohm). Each multi-channel amplifier is shipped

with one standard wall mount potentiometer.

Simple 3-wire connection to the PLC4.1.

POWERLINX PRODUCTS

PLA305 5-Channel Power Amplifier

The PLA305 amplifier resides in the 110 series subwoofer cabinet. All internal woofer connections are made for

you at the factory. Four external 50 watt full-range speaker connector sets are accessible on the front panel of the PLA305.

1) PREAMP INPUT

Accepts the supplied 30 cable from the PLC4.1. Audio signals from and power to the PLC4.1 are routed via this
cable. Note that the PLC4.1 module may be temporarily located remotely, with the 12 cable option,

to facilitate system set-up

2) SPEAKER OUTPUTS

Four separate 50 watt speaker-level outputs are provided. Each output should be limited to a minimum of 3 ohms
speaker load. Wire connections are made via spring-loaded push-and-release connectors (maximum wire size; 14
gauge). Your choice of plenum-rated speaker wire should be made with consideration for length of run and damping
characteristics. Be sure to observe consistent phasing of your full-range speakers and avoid shorting of
speaker wires.

3) POWER CORD

110VAC 60 Hz 5A. A standard 2-prong plug is provided. There is no power switch on the PLA305. Automatic power
on/off is made in the presence or absence of an audio signal.
