How to Operate the MX151

Volume Control

Adjust the VOLUME Control to select the desired

listening level. The Volume Control adjusts all eight

channels simultaneously, and level is indicated from 0

to 99% on the bottom line of the Front Panel Informa-

tion Display. The Remote Control may also be used to

adjust the listening level by using the VOL+/- Push-

button.

During the time VOLUME Control is rotated or the

Remote Control VOL+/- Push-button is depressed, an

On-Screen Display Overlay will appear showing the

Volume Level % and a horizontal display bar. Refer

to figure 55. When the MUTE Push-button is pressed,

the Front Panel Information Display will indicate

the word “Muted” in place of the volume % and the

On-Screen Display will replace the word “Volume:”

with “(Muted). Refer to figure 56. Pressing the MUTE

Push-button a second time, the listening volume level

will be restored and the displays will again indicate

the Volume %.
