The MUON command inserts silence between two phrases to be played. This command can be inputted when the NCR

signal of the corresponding channel is "H" level.

Repeated playing back (the SLOOP command) of the MUON command is not possible.

The silence duration (tmu) is specified by the M7-M0 bits and can be set from 20ms to 1,024ms in 252 steps at 4ms intervals.

The equation for setting the silence duration (tmu) is as follows.

However, set the silence setting (M7-M0) to 04h or more (tmu≥20ms).

tmu=(2

7×(M7)+26×(M6)+25×(M5)+24×(M4)+23×(M3)+22×(M2)+21×(M1)+20×(M0)+1)×4ms

The channel settings are as follows:

Channeled

Description

CH0

Setting this bit to 1 inserts silence into channel 0.

CH1

Setting this bit to 1 inserts silence into channel 1.

CH2

Setting this bit to 1 inserts silence into channel 2.

CH3

Setting this bit to 1 inserts silence into channel 3.

Be sure to specify one of the channels for the channel setting (CH0-CH3).

Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is

ignored.

For the timing of the MUON command, refer to the "Playback start timing by MUON command" in the timing chart.

For the timing of continuous playback, refer to the "Continuous playback timing by MUON command" in the timing chart.
