Carvin CX420 manual Tape Decks and External Effects

TAPE DECKS AND EXTERNAL EFFECTS

The basic hook up is simple, using four (or two stereo) RCA cables plug the tape send on the mixer into the tape deck’s inputs, and the mixer’s tape return’s into the tape deck’s outputs. This will of course be a mono

AUX EFFECTS PROCESSOR

mix because the CX630 and CX420 are mono mixers, but for playing back pre recorded stereo tapes this hookup allows both left and right sides to be heard. For play back turn up the TAPE/ EFF RTN level con- trol to the desired play back volume. For setting the recording level the MAIN level control is used. Also, when recording turn down the TAPE/ EFF RTN level as feedback may occur through the tape deck.

With an effects processor, plug the EFFECTS SEND 1/4” phone output on the mixer into the input jack on the effects processor, and plug the EFFECTS RETURN 1/4” phone input on the mixer into the output jack on the effects processor. Use the EFF SEND level control to adjust the volume sent to the external effects unit, and use the TAPE/ EFF RTN level control to adjust the return volume heard in the main mix.

4. TAPE/EFFECTS RETURN LEVEL CONTROL

The TAPE/ EFF RTN is an effects or tape return volume control. It can receive input from both the tape return RCA jacks and the 1/4” effects return jack. This volume controls the return level being fed back into the main mix. The return can also be used as just another input to the main mix for a keyboard or other gear.

5. REVERB RETURN LEVEL CONTROL

The REVERB return level control is the volume control for the internal reverb tank. This volume controls the amount of reverb heard in the main and monitor mixes.

6. MONITOR LINE OUT JACK

The MONITOR LINE OUT jack is where the MONITOR master level control’s signal can be accessed. This is a line level output and can be used to drive an external power amplifier or it can be plugged into the AMP PATCH jack to drive the graphic EQ and the internal power amplifier.

7. MAIN LINE OUT JACK

The MAIN LINE OUT jack is the post EQ output jack for the main mix. This out- put is the same signal that is being feed to the internal power amplifier.

Note: If the AMP PATCH jack is being used for patching the monitor out to the internal amplifier, then that new signal will also be present on the MAIN LINE OUT jack. The original main mix may still be accessed at the RCA TAPE SEND jacks in this case.

8. AMP PATCH JACK

The AMP PATCH jack is pre-graphic EQ and normalized to the main mix. When something is plugged into this jack, the main mix is disconnected from the graphic EQ and internal power amplifier and the new signal, that was plugged into the jack, is now going through the graphic EQ and to the internal power amplifier. Also this new signal appears at the MAIN LINE OUT jack. A typical use for this jack is where power for monitor speakers is needed and a larger external power amplifier is to be used for the main speakers. Here the monitor line out jack can be plugged, or “patched” into the AMP PATCH jack for a pow- ered monitor mix.

9. TAPE SEND AND TAPE RETURN RCA JACKS

The TAPE SEND RCA jacks deliver the main mix output pre the graphic EQ uninterrupted by the status of the AMP PATCH jack. The two jacks are linked internally together so either or both can be used. Also, the TAPE SEND jacks are a way to access the main mix, if the amp patch jack is being used.

The TAPE RETURN RCA jacks are RCA inputs to the TAPE/ EFF RTN level control. The tape return jacks can also be used for returning another effects processor or instrument such as a keyboard to the main mix.

These RCA jacks are Ideal for using a cassette deck to record a mix with the tape send jacks and then playing it back through the tape returns without using up any channels or having to use adapters to hook up the cassette deck.
