Re: Mackie CR4 amplifier no sound
Mute pin function, see PDF. It is not just LO or HI, it has Standby mode, Mute mode, and Play mode.
MUTE STAND-BY FUNCTION
The pin 5 (MUTE/STAND-BY) controls the amplifier
status by two different thresholds, referred to
+VS.
- When Vpin5 higher than = +VS - 2.5V the
amplifier is in Stand-by mode and the final
stage generators are off.
- when Vpin5 is between +VS - 2.5V and +VS
- 6V the final stage current generators are
switched on and the amplifier is in mute
mode
- when Vpin5 is lower than +VS - 6V the amplifier
is play mode.
