Mute Control
The PA 2-50 has a Mute function that can be accessed via IR or serial RS-232 remote control.
When accessed from the IR remote, pressing the Mute button toggles the Mute function. When
accessed via the RS-232 serial control, the Mute may be toggled or explicitly turned On of Off.
Resetting a fault
If the PA 2-50 experiences a short of other fault, the PA 2-50 will return to Standby mode and the
Standby LED will ash red. To reset the protection, turn the PA 2-50 Off and then On again using the
REAR PANEL POWER SWITCH after the fault has been removed. If the fault indication remains,
please refer to the Troubleshooting section for more options.
Volume Lockout
The Sherbourn PA 2-50 has a special user Volume control lockout feature. This feature is engaged
by pressing the front panel Input 1 button and holding it for approximately 3 seconds. THIS
LOCKOUT MODE WILL REMAIN IN EFFECT EVEN IF THE PA 2-50 IS SET INTO STANDBY
MODE OR POWERED OFF AND ON AGAIN. The lockout mode is disengaged by again pressing
the front panel Input 1 button and holding it for approximately 3 seconds.
When the lockout mode is engaged, the front panel Volume controls and the IR Volume control
are disabled; the RS-232 Volume control functions will still operate normally. (This is not a Mute
function; the Volume remains set as it was when the lockout was initiated.) When the Input 1 button
is pressed to engage the lockout mode, the Input selection will also switch to Input 1. Since the
Input selection controls are not locked out, Input 2 or Auto may be re-selected afterwards.
