Overview
|
The HD-RA35UA is a four
input audio mixer amplifier for systems demanding the broadest
range of features and the highest energy efficiency. Two output
power amplifier zones, 35 watts (Zone 1) and 4 watts (Zone 2), are
driven from high-efficiency Class D amplifier stages
The mixer and amplifier sections all normally shut down (standby
sleep mode) when audio is absent and automatically turn on when
needed. A paging source is normally connected to Input 1
The Zone 1 amplifier output level for inputs 2, 3 and 4 is VCA
controlled using various optional RDL remote controls. This allows
the user controls to be conveniently wall mounted without running
audio to and from the remote control location
The Zone 1 output provides a constant voltage output (25 V, 70 V
or 100 V). The Zone 2 amplifier output drives an 8 ohm speaker and
or 600 ohm telephone equipment
The HD-RA35UA is engineered, tested and manufactured in the U.S.A.
to strict energy conservation standards. The unit consumes less
than 1W of mains power in standby mode, and meets power amplifier
efficiency specifications with analog-filtered Class-D digital
output stages for both power amplifier output zones and for the
600 ohm output
The HD-RA35UA features two mixers. The Zone 1 mixer is split
between the front-panel (Paging Input 1 and tone controls) and a
remote control (Inputs 2, 3 and 4) providing user level controls
for the 35 watt amplifier output
The tone controls adjust the equalization at the Zone 1 amplifier
output and can be switch selected on the rear panel to also adjust
the equalization at the line-level output
The Zone 2 mixer on the rear panel provides level trimmers
normally set by the installer to provide music-on-hold and or for
background music in a small zone equipped with an 8 ohm speaker.
The Zone 2 section includes a 4 watt amplifier, a 600 ohm
transformer-balanced MOH output, and an active balanced line-level
output that may be used to feed another audio power amplifier
