Recommended Tape Usage
Use only high-quality cassette tapes with your X-Gen system. Some
inexpensive tapes can cause poor-quality recordings and premature
head wear. For X-Gen Stereo, Ferrite or XL models, you can use either
normal bias 120 ms (Type I) or high-bias (70 ms CrO2/Type II) types of
tape. For Standard model X-Gen duplicators, only normal bias (Type I)
tapes can be used. You can use C-30, C-60 or C-90 cassettes, but
C-120 cassettes are likely to break and thus are not recommended.
NOTE
Metal (Type IV) tapes are not recommended.
Warranty Exclusion
Telex does not warrant or quarantee the performance of the X-Gen tape
duplication products in configuration with any hardware that is not the
standard. If you have any questions on this matter, please feel free to
contact Telex Communications, Inc.

Copying With X-Gen
Before you perform any copying task with your X-Gen, follow the steps
described below in
Set Up the X-Gen for Copying .
Setting Up the X-Gen for Copying
Use this procedure to prepare the X-Gen system for copying in Manual
mode, Automatic mode, or for any specialized copying tasks.
1. Switch the X-Gen modules on.
2. If you purchased an XL or Ferrite Stereo Model and will be copying
with chromium dioxide (CrO2) tape, refer to table on page 6.
3. Insert the cassette you wish to copy from into the Master well as
shown in Figure 1.
CAUTION
Never run your master (original) cassette in any of the
X-Gen’s
Cop y wells or the recorded information will be lost.
4. Insert the cassettes you wish to copy onto in the
Copy wells of the
Control module and Copy modules.
8
Figure 1. Cassette Insertion

CAUTION
If you are using high-bias (CrO2) tape for recording on an XL or
Ferrite model of X-Gen, bulk erase each cassette that you place into
a
Copy well. If you are recording on normal bias cassettes, X-Gen
automatically erases previously recorded material.
5. If you want the copy from one side of the master cassette only, press
and hold the
Side Select switch to set it to A. To change back to
automatically copying both sides of the master cassette, toggle
(press and hold) the
Side Select switch back to AB.
6. Set the recording levels for each channel, by performing the
following steps.
a. Set the
Auto/Manual switch to Manual .
b. Press
Copy .
c. Monitor the recording levels for each channel.
d. For each channel that needs adjustment, rotate its knob as
needed. Adjust each channel to stay as close as possible to the
0 dB indicator. Occasional peaks of +3 are acceptable, but
peaks of +6 produce poor copies. After the adjustment for each
channel is correct, press the knob down, to prevent your setting
from being accidentally disturbed.
e. Repeat step 6d for each channel.
7. Press
Stop and then Rewind to rewind all cassettes to their
beginnings. To begin copying, go to one of the following procedures:
Manual Copying , Automatic Copying , or Special Copying
Applications
.
9

Manual Copying
Use this procedure to copy cassettes in Manual mode. Manual mode
requires you to rewind cassettes, using the
Rewind button.
1. Set up the X-Gen for copying, as described in the procedure
Setting
Up the X-Gen for Copying
on page 8.
2. Set the
Auto/Manual switch to Manual .
3. Set the
Side Select switch as desired. To change to the AB position
(both sides of the master will be copied at the same time) or to the A
position (copy one side only), press and hold the
Side Select switch.
4. Press the
Copy button to begin copying.
5. Monitor the copying process. Copying will stop when a copy
cassette reaches its end. Use the
Stop and Rewind buttons as
needed, to stop copying or to rewind the cassettes to their
beginnings.
6. After a Copy cycle, check the
Short Tape indicators for each Copy
well. A Short Tape indicator lighted red means that the copy tape
stopped copying before the master tape reached the end, so the
copy tape in that well might be incomplete or defective.
Automatic Copying
Use this procedure to copy in Automatic mode. In Automatic mode, the
X-Gen rewinds all cassettes to their beginnings both before copying and
after copying.
1. Set up the X-Gen for copying, as described in the procedure
Setting
Up the X-Gen for Copying
on page 8.
2. Set the
Auto/Manual switch to Auto .
3. On each X-Gen module, press and hold the
Side Select switch to set
the module to the
AB position. (Both sides of the original will be
copied at the same time.)
10

4. Press the Copy button. First, all tapes will automatically rewind, then
copying will begin. After copying finishes, all tapes will rewind to
their beginnings, the
Stop indicator will light, and a one-second tone
will sound. To stop copying at any time, press
Stop.
5. After a Copy cycle, check the Short Tape indicators for each Copy
well. A Short Tape indicator lighted red means that the copy tape
stopped before the master tape reached the end, so the copy tape in
the corresponding well might be incomplete or defective.
Special Copying Applications
Single-Side Copying
Use this procedure to copy onto one side of a cassette (or cassettes)
only.
1. Set up the X-Gen for copying, as described in the procedure
Setting
Up the X-Gen for Copying
on page 8.
2. To set X-Gen to automatically rewind the cassettes before and after
copying, set the Auto/Manual switch to
Auto . If you are going to
copy from a different master onto the second sides of the copy
tapes, select
Manual .
3. Set (press and hold) the
Side Select switch to the A position.
4. If you selected Auto mode, press the
Copy button to begin the
copying cycle. If you selected Manual mode, press the
Rewind
button; then after all tapes are rewound to their beginnings, press the
Copy button.
5. After a Copy cycle finishes, check the
Short Tape indicators for each
Copy well. A Short Tape indicator lighted red means that the copy
tape stopped before the master tape reached the end, so the copy
tape in that well might be incomplete or defective.
11

Copying Multiple Short Originals Onto Longer Copies
Use this procedure to copy short segments from various master
cassettes onto a single, longer cassette.
1. Set up the X-Gen for copying, as described in the procedure
Setting
Up the X-Gen for Copying
on page 8.
2. Set the
Auto/Manual switch to Manual .
3. Set (press and hold) the
Side Select switch to A .
4. Verify that the master cassette is inserted with the side to be copied
facing up. Verify that the copy cassettes are inserted with the side to
be copied onto facing up.
5. Press the
Rewind button.
6. After all tapes are rewound, press
Copy . Immediately at the end of
the original segment that you are recording, press the
Stop button to
prevent long blank spaces between programs on the copy cassettes.
7. Insert the next master cassette with the side to be copied facing up.
8. The tape in the master must be in the proper position. If it is
necessary to rewind the master to the proper position, first remove
all copy cassettes from all
Copy wells. Then rewind the master to
the proper position and replace the copy cassettes into the
Copy
wells.
9. Press
Copy again and then press Stop immediately at the end of the
original segment on the master.
10. Repeat steps 6 through 9, to copy from other master cassettes.

Maintaining X-Gen
Maintenance Cautions and Warnings
·Do not use soap and water, cleaning solvents, or furniture wax
on the modules. To keep modules free of dirt and dust, cover the
modules when not in use. Clean the modules periodically by
wiping with a dry, lint-free cloth.
·For cleaning parts that come into contact with cassette tape, use
only isopropyl alcohol (at least 90% pure) or a high-quality liquid
head cleaner. Using other fluids can cause damage.
·Never touch the tape heads with any hard or sharp objects, stiff
brushes, or anything made of metal.
·Do not exert pressure on heads or realignment may be needed.
Cleaning the Tape Head, Capstan, and Pressure
Roller
To ensure the best copy quality, clean all cassette tape contact points
regularly, as described and shown below. The frequency of cleaning
required depends on frequency of use, type of tape being used, and
environmental conditions (for example, a dusty room).
It is especially important to keep the tape heads clean, because improper
tape contact with the tape heads causes dropouts, fading, and a
noticeable loss in high-frequency response on the copies.
1. Remove all cassettes from the
Control and Copy modules.
2. While pressing and holding the Control module’s
Stop button, press
the
Copy button. The heads and rollers will engage (but the spindles
won’t move) to allow cleaning.
13

3. Use a cotton swab or a soft, lint-free cloth lightly dampened (not
saturated) with isopropyl alcohol to clean the tape heads, pressure
roller, and capstan in each well. When cleaning the pressure roller
and capstan, place the cotton swab in contact with the surface
farthest away from the tape head as shown in Figure 2.
4. After you finish, press the
Stop button to exit from the cleaning
mode.
