21.Bouncing

Sometimes you want to play back from one or more tracks, route the signals to a new track or pair of tracks, and re-record. This process is commonly referred to as bouncing. Examples would be when reducing 4 lead vocal take tracks down to 1, reducing 4 separate tom-tom tracks down to a stereo pair via noise gates, putting a wild effect or EQ onto a dry signal, “comping” backing vocal tracks, etc.

On an analog tape recorder, bouncing to an adjacent track is to be avoided.

A feedback loop can be set up, since for all overdubs or bounces you will be using the same (sync) head for both playback and record. Organize your track layout so that any bounces you might have to do are always over at least one track.

There are no restrictions when using digital multitracks.

Tab. 22.1: Input/output configuration

The EXPANDER PORT inputs have a nominal level of -2 dBu (subgroup/mix) and +2 dBu (aux).

◊All variable gain circuits offer +15 dB (except aux returns, which offer +20 dB).

◊All balanced jack sockets are automatically unbalanced when using an unbalanced jack patch lead!

◊Links should not be threaded into holes on the PCB. They should be soldered to the tinned areas around the holes, and bowed slightly upwards in between.

23.1 Aux sends > post EQ

All channel aux sends are post mute and pre fader. If you want to convert these to post EQ, carry out the following modification to each channel. You will find a corresponding printing on the PCB (see fig. 23.1).

1)Disconnect power supply.

2)Cut the “post mute” track.

3)Add in a “post EQ” link.

4)Repeat for all channels you want to be modified.

Fig. 23.5: Modifications aux send > post EQ

23.2 MIX-B source > post fader

That’s it. You’ve decided to use the MIX-B as a stereo aux send to FX rather than a separate stereo feed. You can move the tap from the A-channel from pre to post the channel fader as follows. Again, look for the printing on the PCB shown below.

1)Disconnect power supply.

2)Cut the “pre” track.

3)Add in a “post” link.

4)Repeat for all channels you want to be modified.

Fig. 23.5: Modifications MIX-B source > post fader

23.3 LED meters > pre fader

In channel mode the meterbridge monitors the DIRECT OUT signal (post EQ, post mute and post fader). You would prefer to see what’s going on pre mute and pre fader? Once you found the corresponding printing on the PCB, all you have do is:

1)Disconnect power supply.

2)Cut the “line out” track.

3)Add in a “pre fade” link.

4)Repeat for all channels you want to be modified.
