Troubleshooting

If the MRS-4 does not seem to function normally, check the following points first.

The recorded sound is distorted

• Check whether the input sensitivity

setting ([INPUT LEVEL] controls 1/2)

was appropriate.

Mixdown effect does not operate

Make sure that the [SEND/RETURN] key is flashing or lit in green. If the key is not lit, press the key to make it light in green.

Troubleshooting

Playback problems

No sound, or very low volume

Check the connections to your monitor system, and the volume of your monitor system.

Make sure that the status keys 1 – 4 are lit in green. If a key is not lit, press the key to make it light in green.

Make sure that the track faders 1 – 4 and the MASTER fader are raised.

Make sure that a SmartMedia card is inserted in the card slot.

Operating the fader does not affect the volume

On channels for which stereo link is turned on, the fader of the even-numbered channel will have no effect. Either turn stereo link off (p. 39), or operate the fader of the odd-numbered channel.

Recorder stops midway during play

When performing playback with a status key lit in red, a temporary file is created internally by the MRS-4. If the remaining capacity of the SmartMedia card then becomes low, playback is stopped midway through the song. In such a case, press the status key so that it goes out or is lit in green.

Noise occurs during mixdown

Make sure that the [ON/OFF] keys 1/2 are out.

Check whether the mixdown effect is set to an extreme setting.

Problems with recording

Input signal is not heard, or very low volume

Make sure that the [ON/OFF] keys 1/2 are lit.

Make sure that the [INPUT LEVEL] controls 1/2 are turned up.

Can't record on a track

Make sure that the status key of the track selected for recording is lit in red.

Recording is not possible if the song is protected. Either turn protect off (p. 49), or use another song.

Make sure that a SmartMedia card is inserted in the card slot.

The signal from the [AUX IN] jacks cannot be recorded on a track. Connect the sound source for recording to the [INPUT 1]/[INPUT 2] jacks.

Cannot perform bounce

Make sure that the [BOUNCE] key is on.

Make sure that the status key of the track selected as bounce destination is lit in red.

Make sure that the track faders 1 – 4 and the MASTER fader are raised.

• Lower the track faders or MASTER fader

so that the 0 (dB) dot of the level meter

does not light.

• If the EQ gain of the track mixer is set

extremely high, the sound may be audibly

distorted even if the fader is lowered. Set

the EQ to an appropriate value.

Problems with effects

Insert effect does not operate

Make sure that the [SEND/RETURN] key and [MIXDOWN] key are flashing or lit in red.

Check that the limiter and compressor settings are not too low for the input level.

Send/return effect does not operate

Make sure that the [SEND/RETURN] key is flashing or lit in green. If the key is not lit, press the key to make it light in green.

Make sure that the SEND parameter for each mixer track is on and that the SLVL parameter is set to a suitable value.

Problems with MIDI

Cannot synchronize with external MIDI device

Make sure that the [MIDI OUT] connector on the MRS-4 is properly connected to the MIDI IN connector on the external MIDI device with a MIDI cable.

Make sure that the external MIDI device is set up to receive a timing clock signal for synchronized operation.

Make sure that the external MIDI device is set to the playback condition.

Make sure that the metronome tempo and time signature settings match the song on the external MIDI device.

Other problems

Cannot use tuner function

The tuner cannot be used during song playback. Stop the song before using the tuner.

Make sure that the [ON/OFF] key of the respective input is on, and the [INPUT LEVEL] control 1/2 is raised.

One of the following messages appears on the display
PLYSTOP

This operation cannot be carried out during recorder operation. Stop the recorder first.
