User manual YAMAHA M-4

[. . . ] The research, engineering, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division. WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). [. . . ] · Input selection (including ZONE2), 6CH input · REC OUT switching · ZONE2 input, volume · Front/Center/Rear/Sub-woofer level adjustment · Muting · Speaker A/B · Power on/off operation · Master volume It is possible to set to the following volume values using the remote control unit Volume value (dB) Remote control code (key) 0 7A---E0 (TUNER CHP/INDEX) -21 7A---E1 (TUNER 9) -40 7A---E2 (TUNER 10) MUTE 7A---E3 (TUNER 11) only during DIAG being set. * Functions related to the tuner and the set menu are not available. * It is possible to confirm Menu No. 11 "IF STATUS" while keeping the signal process (operation status) of each DIAG menu by using the INPUT MODE key of the main unit. q Initial settings used to start DIAG function Following initial settings are used when starting the DIAG function. When the DIAG function is canceled, the settings before starting DIAG will be restored. · Input, ZONE2 input: DVD (6CH INPUT OFF) · Master volume: -40dB · ZONE2 volume: -6dB · Front/Center/Rear/Sub-woofer level: 0dB · Audio mute: OFF · Speaker A/B: ON · Speakers Settings MAIN: LARGE CENTER: LARGE REAR: LARGE REAR CENTER: LARGE BASS OUT: BOTH FRONT EFFECT: YES MAIN LEVEL: Normal (0dB) · DIAG menu: DSP THROUGH (ANALOG BYPASS) 13 M-4 M-4RDS M-4/M-4RDS Details of DIAG menu 1.

[. . . ] (2fsc or 4fsc) Switching terminal between the mode to input a clock externally and the mode for crystal oscillation. [L] = Crystal oscillation, [H] = External clock input Terminal to output the blank signal (character and bordering OR signal) (MOD0 : complex synchronous signal output at [H]). When resetting (RST terminal = [L]), a crystal oscillation clock is output (but not when resetting by the command). LC oscillation terminal Terminal to connect the coil of the oscillator for character output dot clock generation and a capacitor. [. . . ]
