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.
