This chapter explains how to perform ping-pong recording
using Additional tracks L and R.
In this example session, we ping-pong record tracks 1–4 to
the Additional tracks.

At this time, check the recording level of the Additional
tracks via the level meters L and R. Adjust the input
channel faders so that the [OL] section of the level meters
L and R will not light up continuously.

8. Adjust the channel equalizers, if necessary.

9. Turn the AUX knob of the channel signal to which you wish

to apply effects toward AUX 1. Use the AUX RTN 1 knob to
adjust the return signal level.

At this time, make sure that the [OL] section of level meters
4 and R do not light up continuously.

10. Raise the MASTER knob in the monitor section gradually

to listen to the mix sound to be ping-pong recorded.

When you finish adjusting the level, effects, and balance,
stop the recorder section and locate the top of the
Program.

Performing ping-pong recording

11. Holding down the RECORD button and press the PLAY

button to start recording.

Quitting ping-pong recording

12. Stop the recorder section, and initialize the FD-4.

Checking the result of ping-pong recording

Because any sound that has been ping ponged onto the
additional track cannot be checked directly, the additional
track and a real track must be temporarily exchanged.

Ping pong recording

(Original sound and

effected sound)

<Notes>

This function is available only when you are using a disk

formatted in Normal mode or Mastering mode 1.

You cannot use a disk formatted in Mastering mode 2, which

allows for normal ping-pong recording.

You cannot play back data recorded on Additional tracks. To play

back the data, move it to Real tracks 1–2 or 3–4.

• Initialize the FD-4 before you start the operation.

• If multiple Programs exist, select the desired Program first.

Connecting effect units

1. Connect effect units to Aux sends/returns.

Setting the switch and knob

1. Set the channel 1–4 INPUT SEL switches to TRK.

Tracks 1–4 playback signals are routed to the
corresponding input channel faders.

2. Turn the channel 1–4 PAN knobs all the way [L] or [R]

depending on the sound sources so that they will be
recorded to Additional tracks L and R.

3. Set the monitor SELECTOR to L/R.

You can monitor the stereo bus L/R output signals.

4. Press the RECORD TRACK select keys L and R.

5. Raise the master fader L/R to 7–8.

Adjusting the recording level/rehearsal

6. Start playing the Program from the beginning.

Since Additional tracks cannot be set to input
monitoring mode, you do not have to press the RECORD
button at this time.

7. Use the channel 1–4 input faders to adjust the track output

levels.

1. Use the Track Exchange function to swap data between the

Additional and Real tracks.

• See “Track Exchange” on page 60 for more information on moving

data between tracks.

2. Set the monitor SELECTOR to MON.

3. Play the Program from the beginning.

4. Turn the MON knob of the channel (to which you moved the

data) toward [TRK] and turn the MASTER knob in the
monitor section gradually to audition the sound.

After exchanging the additional track with the real track and check-

ing it. UNDO/REDO can be executed in the same way as with

the previous “ping pong recording” if you are not satisfied after

checking it.

If UNDO is executed after checking the sound, it can be re-

turned to the state prior to executing ping pong.

If REDO is executed after execution of UNDO, it can be re-

turned to the state prior to the second execution of UNDO (The

state upon moving to the real track).
