Troubleshooting

MT8XII—Owner’s Manual

Troubleshooting

If you’re having difficulty operating MT8XII or it doesn’t seem to work as expected, look up the
symptoms in the following table and follow the advice provided.

Symptom

Advice

MT8XII cannot be turned on!

Make sure the power cord is connected to a suitable AC wall outlet and
plugged into the AC IN connector at the rear of the MT8XII.

Make sure that the MT8XII POWER switch is set to the ON position.

If you still cannot turn on your MT8XII, contact your Yamaha dealer.

Cannot listen to a connected
music source!

Make sure that the input selector switch is set to MIC/LINE. Raise the
input channel fader. Assign the input channel to a track using the
GROUP ASSIGN switches. Press the corresponding MONITOR SELECT
GROUP switch. Turn up the MONITOR LEVEL control.

Cannot record!

Make sure the tape’s write protect tabs are intact.

Be sure to press a [REC SELECT] button to select a track for recording?

Make sure that you have actually assigned the signal that you want to
record to the track. Use the CUE monitor controls to see if the signal is
actually being sent to the track.

The level meters do not
indicate signal levels!

Normally, the level meters indicate tape signal levels. To see the level of
a group signal you must press the corresponding [REC SELECT] button.

Recordings are noisy!

Use the dbx noise reduction.

Make sure that the recording level is set correctly. Too low a signal level
will cause the tape hiss to be more noticeable.

Recordings are distorted!

Make sure that the recording level is set correctly. Too high a signal
level will cause distortion.

Recordings sound dull!

Clean the record–play head and other parts of the tape transport.
Demagnetize the record–play head.

Abnormal tape hiss!

Wow and flutter

Fluctuating output level!

Recordings play back at the
wrong pitch!

You may have adjusted the pitch prior to recording a track. Reset the
pitch as required.

Cannot send a channel
signal to the AUX SEND!

As well as turn up the AUX control you must also raise the channel
fader. This is because the AUX SEND signal is sourced post-fader (i.e.,
after the fader).

MIDI sequencer does not
synchronize to the MT8XII!

Have you recorded a SYNC signal on Track 8?

Make sure that the FSK/MIDI or SMPTE/MIDI converter is set to con-
vert the recorded SYNC signal into a MIDI Clock signal.

Make sure your MIDI sequencer is set to synchronize to an external
source. Refer to the MIDI sequencer’s user manual.
