How to use the XR-7
Some things you can do with the XR-7
Radio cassette players and stereo cassette decks record and play back stereo sound on both
sides of 3 tape: side A and side B. As shown in the diagram, a cassette tape is divided into
four tracks. Two are used for side A and two for side B.
However, the XR-7 uses all four tracks at once (i.e., as a single side) and is able to record
each track independently, allowing you to record instruments or vocal parts separately.
This chapter provides examples of the possibilities of the XR-7, and explains some basic
concepts you should understand.
Recording a four-piece band
The XR-7 has four tracks, and a different sound source can be recorded independently on
each track.
Here's how you might record a four-piece band (drums, bass, guitar, and keyboard). Record
the drums on one track. Then, while you play back the drum part you recorded, record the
bass part on a second track. (This process is called "overdubbing.") As shown below, use the
same procedure to record the guitar and then the keyboard on the remaining tracks to
complete a four track recording.
3

CHAPTER
1
How to use the XR-7
Direct recording
The XR-7 allows you to overdub four tracks one by one, and also to record four different
sound sources on four tracks simultaneously. This is called "direct recording."
Recording a multitrack performance by yourself
if you a re able to play more than one instrument, a multitrack recorder can be a very valuable
music-making tool. For example, six channels carrying six different sounds can be routed
to two tracks. If you are able to use MIDI instruments, you can use the tape sync function to
create large orchestral arrangements. This manual will explain first how to record one sound
source on a single track, and gradually move on to more complex possibilities.
Once you understand the basic principles, multitrack recording is quite simple and easy.
Using professional recording techniques
You may record a favoritesongbyyour favorite professional musician, then record your own
performance on a different track, accompanying the song. By using the pitch control to slow
■ down the tape speed, you can more easily transcribe and learn how to play rapid phrases.
You can also practice your part to your satisfaction using the instrument rehearsal mode {*)
with a normal tape speed. If you make a few mistakes, these can be easily corrected using
the punch in/out function with the rehearsal function. Try out these professional techniques.
(*) Refer to the Rehearsal button section on page 11 to learn how to switch the tape speed
to nonnal speed. However, "Rehearsal" and "Pitch control" do not function when normal
speed is selected.
Some important terms used in this manual
This section explains some of the important terms used in this manual, which you need to
understand in order to take advantage of the XR-7.
Sound source
Instruments or microphones connected to the XR-7 are collectively called "sound sources."
Signal
The XR-7 is able to record not only sound from sound sources, but also FSK signals used by
the tape sync function. Thus, sounds and signals are collectively explained as "inputsignals"
or "output signals."
Overdubbing
The process of playing back a previously-recorded signal on one track while recording a
different signal on another track is called "overdubbing."
On cassette radio players or stereo cassette decks, it is not possible to listen to the sound
recorded on the left track while recording a new sound on the right track. However, the
XR-7's overdubbing capabilities allow you to successively record new sounds on empty
tracks.
Monitoring
As explained above, "overdubbing" includes the act of listening to a previously-recorded
sound. This "listening to a previously-recorded sound" is often referred to as "monitoring."
The word "monitor" means to check or verify, and in this manual's explanation of the
recording process, listening to a previously-recorded track or checking the input signal to
be newly recorded is referred to as "monitoring."
4

The difference between Tracks and Channels
Tracks and Channels are often confused. In ihis manual, they mean different things.
Channels refer primarily to the input/output system of the mixer section. For example, this
manual tells you (hat "the bass connected to channel 1" should be "output from the Left
channel." Tracks, on the other hand, refer mainly to the recorder section (the tape). For
example, this manual may tell you to "mixdown tracks 1, 2, 3, and 4." In other words, the
XR-7 contains a four-channel mixer section and a four-track recorder section.
Input monitor and Tape monitor
"Monitoring the output from the recorder section" is often interpreted as "listening to the tape
playback." However, to be precise, it has two meanings as follows:
Tape monitor
Listening to the tape playback.
Input monitor:
Listening to each track signal that is dtreclly output from the recorder section while recording
or while in recording standby mode.
Recorder
All tracks are

CHAPTER
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."
6

About cassette tapes for the XR-7
Suitable types of cassette tape
The XR-7 is designed to use high-position cassette tapes (Chrome, type II), and will give the
best performance when used with tapes such as Maxell XLII or TDK SA cassettes. We
recommend thatyou use either these tapes or other tapes of equivalent quality. Since C-120
cassettes use thinner tape, they are not suitable for multitrack: recording, where repeated
recording and playback takes place. Avoid using anything longer than a C-90 with the XR-7.
Using the erase-protect tabs
Cassette tapes have "tabs" that can be broken off to prevent valuable recordings from being
accidentally erased. Since the XR-7 uses all four tracks as a single side, break off the tabs for
both side A and side B to prevent a completed recording from accidental erasure.
If you later decide to record over the tape, you apply a piece of tape (duct tape or electrician's
tape, etc.) over the broken-off tab holes so that the cassette can be re-recorded.

You can connect up to six sound sources to the XR-7. Take special note that you can adjust
the level using the TRIM knobs for the sound sources connected to the [INPUT] jacks 5 and
6, which allows you to connect either mic level or line level instruments.
Using the [TRIM] knobs:
You can adjust the level of the signal input to the
[INPUT] jacks 5 and 6 according to the output
level of the connected sound sources. We
recommend you connect the microphone to the
[INPUT] jack 5 ore andadjustthe level using the
TRIM knobs as lollows;
When a low-level source such as a micro¬
phone is connected:
Rotate the knob clockwise (toward “-60").
When a line-level source such as a synthe¬
sizer is connected:
Rotate the knob counter-clockwise (toward
Using the [INPUT SEL] switches
Set the [INPUTSEL] switches as follows according to the signal routed to the [INPUT] faders.
The signal adjusted by the [INPUT] fader goes from the [INPUT] fader through [EQ] and
[PAN], to the stereo bus. (However, in direct recording, the signal is routed directly to the
recording section from the [EQ] section, and it is not sent to the stereo bus.)

■ INPUT”: The signal input from the [INPUT] jacks is controlled. This
setting is usually used to record the sound source connected
to the corresponding [INPUT] jack.
“TAPE”: The tape playback signal is controlled. This setting is usually
used to adjust each track signal and record to a master
recorder.

[REC SELECT] switch [PAN] knob settings
[REC SELECT] switch settings
“ 1 , 2 , 3 , 4 ”
Use this setting when you are recording the [INPUT] jack 1-4 signal
directly to tracks 1-4.
“L, R"
Use this setting when you are recording the signal to tracks 1-4 via the
stereo bus. Stereo bus L signal is recorded to track 1 or 3. and stereo
bus R signal is recorded to track 2 or 4. Use the [PAN) knobs to route
the signal to each track.
[PAN] knob settings
Rotate the knob far left Rotate the knob far right
to send the signal to to send the signal to the
the stereo bus L stereo bus R.
Basically, the [PAN] knobs are used to route
the input signal to stereo bus L (track 1 and
3) and stereo bus R (track 2 and 4).
Rotate the knobs far left or far right to send
the input signal to stereo bus L or R,
respectively.
Adjust the stereo image
as you wish.
During mixdown, use the [PAN] knobs to
determine the stereo image of the tape
playback signal routed to channels 1-4. In
direct recording, use these knobs only to
adjust the stereo image of the monitoring
signal.
Relationship between the [PAN] knobs and [REC SELECT] switches
Usually, the channel signal via stereo bus is routed by the [PAN] knob and [REC SELECT]
switch settings to the tape.

Prepara^on
How to monitor the signal
To monitor the signal, connect your headphones to
the [PHONES] jack; or connect an amp with a
builMn speaker or a power amp/speaker combina¬
tion to the [MON OUT] jack. To adjust the monitor¬
ing level, raise the [MASTER] fader and rotate the
[MONj.knob.
[MON SEL] switch settings
Select one ofthe following settings according to the
type of monitor signal:
“STEREO”
Use this setting most of the time. You
can monitor only the stereo bus L7R
signal.
“ST+FB”
This setting allows you to monitorthe
mix of the stereo bus signal and the
[FB] signal. For example, during
overdubbing, you can monitor the
tape playback signal and recording
signal simultaneously.
“FB"
You can monitor only the [FB] signal.
Adjusting the input signal
You need to obtain an appropriate recording level before you start recording.
it is important to set the recording track to input monitor in order to adjust the input signal
as follows:
Select a recording track.
♦
Press the [REC] button to set the recording track to input monitor.
4
Raise the [MASTER] fader to about 7 or 8,
♦
Raise the [INPUT] fader gradually while playing the instalment, and check the level meter.
(For INPUTS 5 and 6, raise the [INPUT] faders to 7 or 8 and adjust the [TRIM] knob.)
Equalizer settings (Tonal adjustment)
The XR-7 has two types of equalizer: shelving and parametric. They have the following
functions:
Shelving equalizer
This allows you to equalize only channel 1—4 signal, controlling the low frequency range
of 100Hz ±12dB, and high range of 10kHz ±12dB.
Parametric equalizer (Assignable Parametric EQ function)
This equalizer is used to equalize the channel 5 and 6 signal, or the stereo bus L and R. Use
the [EQ SEL] switch to determine which signal is controlled.
The parametric equalizer allows for a fine equalizing of the middle frequency range of
200Hz - 5kHz, in addition to the low and high frequency ranges. Connect the sound source
for a subtle tonal adjustment to the [INPUT] jacks 5 and 6.
Since in multitrack recording the sounds can be layered and re-recorded many times, the
high frequencies may eventually begin soundingduli. Forthis reason it is a good idea to boost
the high frequencies a bit when recording.

Using AUX send/return for effect processing
Connecting an effect unit
You will need to use the AUX send/return
function to route the signal to an effect
processor such as a reverb unit.
The XR-7 has two pairs of AUX sends
(mono output) and AUX returns (stereo
input), allowing you to connect two effect
processors.
Refer to the diagram when connecting
effect units to the XR-7.
If you are using an effect unit that has a
mono output, connect it tolhe "L/MONO"
jack of the [AUX RTN 1] and [AUX RTN
2 ] jacks. (Connecting the unit to the 17
MONO jack automatically causes the identical signal to be sent to the R bus.)
Note on mullitrack recording using the stereo bus (refer to STEP 2):-
When you are using two effect processors that both have only mono outputs for multilrack recording
using the stereo bus, remember the following when making connections:
To send a mono signal from each effect unit to the stereo bus L and R, connect a dummy plug 1o
the [AUX RTN] jack R of the stereo bus L Olherwise, the signal input at the L/MONO jack will also
be routed to the stereo bus R.
[AUX SEL] switch settings
This switch is used to select signals for effect processing.
"CH"
Use this setting to apply effects to the [INPUT] fader signal.
“FB"
Use this setting to apply effects to the [FB] signal (Post Foldback Send function).
For example, select this option when you wish to apply effects to the tape signal
during a tape sync mixdown. (Refer to STEP 8 for detailed procedure.)
[AUX] send, [AUX SEND] master, and [AUX RTN] knob settings
The signal is sent to the connected effect processor and back to the XR-7 via each knob as
shown in the diagram below. Remember that applying an effect to a signal requires
adjustment of three types of knobs.
Effect unit 1
To Stereo Bas L
To Stereo Bas R
[FB] knob settings
The signal sent to [FB] is not routed to the recorder section, but output to the [FB] jack.
These knobs are mainly used to control the tape monitor signal during overdubbing, or to
send the monitoring signal to the players.
Adjusting the knobs as shown in the diagram below will send either signal to [FB],
Rotating the knobcounter-clockwise (toward the “INPUT side) will send the [INPUT]
jack signal to [FB].
Rotating the knob clockwise (toward the “TRK” side) will send the tape playback
signal to [FB].
