Toa RXA-212, Руководство по эксплуатации

Страница: 3 / 20

The RXA-212 is a self-powered console with 12 input channels, 2 program outputs, 2
foldback outputs, 1 echo output, and 2 built-in power amplifiers of 120 watts each into
8 ohms. The RXA-216 is a self-powered console with 16 input channels, 2 program
outputs, 2 foldback outputs, 1 echo output, and 4 built-in power amplifiers of 120
watts each into 8 ohms. Each input channel has a balanced, low impedance,
transformer-isolated, XLR connector, and a high impedance, unbalanced, 1/4" jack.
An input level switch and trim control on each input channel are provided to permit
optimum gain settings. A four-band equalizer is included on each input channel. A
peak indicator LED on each input detects excessive inputs and helps avoid clipping. A
pan control on each input channel assigns the fader output signal of the channel to
program L and R. A cue switch on each input channel, stereo input, aux-echo input,
program output, foldback output and echo send allows monitoring the respective, pre-
fader (pre-volume) signals through the phones output. All faders are log-linear type
with 60mm travel. Two additional stereo inputs are used to connect stereo playback
decks, disk players and other auxiliary equipment. Two independent foldback
outputs are included, (pre-fader, pre-EQ) signals. An analog, electronic echo is built
in, but can be bypassed (via Echo Send/Return) for external delay, reverb or special
effects. Dual Graphic Equalizers (1/1 octave, 9 bands) are switchable to program
outputs, foldback outputs, or "off". A fluorescent bargraph peak meter (2-color,
vertical type) monitors the outputs of program L and R, and foldback 1 and 2. Each
power amplifier is switchable to either program or foldback outputs or can be
connected to external input sources. The RXA-212 and 216 are designed for use in
professional sound reinforcement systems, and provide the versatility necessary to
meet a wide range of requirements. The high performance and modular construction
assures reliability, easy maintenance, and serviceability.
