TP-Link RX-7-248 Features

GROUP/FOLDBACK and GROUP/ECHO MODULES

1. AUX INPUT (Group/Foldback Module) and ECHO IN (Group/Echo Module) are

both balanced (transformer-isolated), with Low, Mid and High-EQ provided for

both types of inputs.

2. ACCESSORY SEND/RECEIVE jacks are located on th e rear of the modules for

inserting signal processing devices.

3. Group On/Off pushbutton allows rapid punch-ins and punch-outs for temporary

killing of an output without disturbing the mixed level.

4. Foldback (FB) MASTER and ECHO SEND controls adjust each output's level

individually.

5. Peak indicators turn on the warn the operator when the signal level reaches l0dB

above nominal.

INPUT MODULE

1. Phantom Power ON/OFF switch.

2. TRIM gain control offers extremely convenient operation when used in

conjunction with INPUT LEVEL switch.

3. MID-EQ is peaking equalization, and its center frequency can be set by a

continuously variable f requency control knob.

4. Two foldback control knobs for the 2 foldback busses. One is Pre-fader and the

other is associated with the PRE-POST selector switch for additional effects.

5. Two echo control knobs for the 2 echo busses. One is Post-fader and the other is

associated with the PRE-POST selector switch.

6. Channel ON/OFF pushbutton provides quick connection or disconnection of the

incoming signal to the mixing busses. The associated green LED illuminates when

the channel is connected to the mixing busses.

7. DIRECT OUT delivers a signal taken directly from the input module, bypassing

the pan pot and group assignment switches. This output is provided for direct

routing to a tape recorder track.

8. ACCESSORY SEND/RECEIVE jacks permit inserting a signal processing device

into the signal path, or can be used to re-route the signal in special applications.

9. PEAK indicator LED turns on when the input signal reaches l0dB above nominal,

to warn the operator to adjust the input sensitivity.
