How to use the XR-7
★ Useful Tip 1 — About the [PAN] knobs and the stereo bus
The XR-7 contains a six channel mixer. This means that you can mix six sound sources to
stereo.
It is not possible to see from the outside how the signals flow. So, we have included a diagram
below that explains the signal routing of the XR-7. The thick pipe in the diagram is called
the stereo bus, and the signals from each [PAN] knob are collected here. After the [MASTER]
fader makes the final level adjustment, the signals are output from the [STEREO OUT L] an'd
[R] jacks.
The [PAN] knobs have the function of routing signals to the stereo bus. The output of the
stereo busis also sent to the recorder section. As shown in the diagram, the output of the L
side is sent to tracks 1 and3,andtheoutputoftheRsideissenttotracks2 and4. For example,
if you wish to record the signals from all channels 1-6 oh track 1, you should set the [REC
SELECT] switch to "L", and set the [PAN] knobs for all channels to the far "L" position.
★ Useful Tip 2 — About the [AUX] system
The [AUX] (auxiliary) system is an auxiliary or supplementary input system. On the XR-7,
however, it is used mainly for effect processing.
The [AUX] signals are provided in addition to the stereo bus explained in the preceding note.
Since all channels 1-6 of the XR-7 can send to the [AUX] system, it is easy to perform effect
processing. It is also possible to apply effect to foldback [FB] signals using the [AUX SEL]
switch. So, you can apply effects to the tape signal during mixdown using tape sync(Post
Foldback Send function),
★ Useful Tip 3 — About foldback [FB]
[FB] is used mainly to monitor the playback signal from the tape during overdubbing. The
reason for using [FB] for monitoring is that the signal from [FB] is sent neither to the stereo
bus nor to the recorder section. The [FB] signal is sent directly out the [FB] jack, and can be
monitored but not recorded. This means that you can monitor the signal from a tape track
without "using up" an input or allowing the monitored signal to get into the track you are
newly recording. By setting the [MON SEL] switch to "ST+FB" or "FB", you can monitor
the [FB] signal through headphones oryour monitor speaker. For details on using [FB], refer
to STEP 3 and 4 "Overdubbing."
