Precautions

1. Each model of the RX-208, RX-212 and RX-216 has two

versions, 120V AC operation only and 220/240V AC operation

with a voltage selector. The voltage selector on the rear panel

of the 220/240V version should be check for proper setting

prior t o operation as improper setting causes trouble. The

voltage selector is set fo r 240V operation at the fact ory.

VOLTAGE SELECTOR

AC220V AC240V

2. Power Switch

The power switch should be on after all connections have been completed.

3. X LR (Cannon) Connectors

The connectors are wired in the following manner: Pin 1 is ground (shield); pin 2 is

cold (low, minus); pin 3 is hot (high, plus).

4. Description of components and functions on the RX-208, RX-212 and RX-216.

In our Operating and Instruction Manual explanation of components and functions

is made according to our usage f or them.

Main Page General Description output has a balanced, low impedance, transformer-isolated, XLR connector, and an input detects excessive inputs and helps avoid clipping. A p an control on each input output and echo send allows monitoring the respective, pre-fader (pre-volume) Features unbalanced 1/4" jack on each input channel and line input. 5. Four-band equalizer on each input channel. or foldback outputs. other auxiliary equipment. Front Panel, Input Section The input trim varies the gain of the pre-amplifier stage of each input channel, providing a The high control in each input channel alters th e frequency response of t he channel input, having flat audio response at the detented "0" position. This control assigns the fader output signal of the channel to the Program L, R mixing busses. Front Panel, Output Section - 4 - Meter Panel RX-208, RX-212 Caution - 5 - The graphic equalizer is normally used for either the PGM or FB mix. For normal operation, only one button should be pressed. If the equalizer is not being used, the "OFF" button should be depressed. Rear Panel (RX-208) RX-208 6 plugs are inserted into these jacks, the input interrupts the return signal from the built-in echo Rear Panel (RX-212, RX-216) The RX-212 and RX-216 are the same as the RX-208 in functions, except that the RX-212 has - 7 - 12 input channels and the RX-216 has 16 input channels.

Page How to use ''channel patching" accessory jack The accessory jack (Tip, Ring, Sleeve) is provided on each input channel to allow insertion of Inserting a plug into the jack interrupts normal signal flow and places the external device into the circuitry just prior to the input equalizer section.
