ADDRESSABLE DUAL MUTING SYSTEM

DUAL MUTING SYSTEM - The Amplifier is equipped with a DUAL noiseless, fast acting Logic MUTING Switching System. When any of the INPUTS are activated and a Signal is present on a given INPUT and either VOX 1 or VOX 2 or BOTH are Switched-ON (using internal Jumpers) then the MUTE 1 or MUTE 2 BUSS or BOTH are ACTIVE. If any of the INPUTS have the MUTE 1 or MUTE 2 Switched-ON (by Internal Jumpers) then the INPUT (or INPUTS) will be MUTED according to the Jumpers Setting. Once the SIGNAL-ON on the ACTIVE INPUT is terminated the normal functions are automatically restored on all muted inputs.

ACCESS TO MUTE JUMPERS

REFER TO JUMPERS AND SWITCHES INTERNAL ACCESS.

CAUTION: PRIOR TO PERFORMING THE ABOVE OPERATION BE SURE TO FOLLOW THE SAFETY NOTES REFERRING TO THE REMOVAL OF THE AMPLIFIER COVER.

MUTING TIMING - The MUTING is preset for -60 db Attenuation. When MUTE 1 or 2 are activated the MUTE BUSS is instanta- neously Switched-ON. When the Muting is deactivated the pro- gram source is gradually restored.

MUTE 1 (M1) = TIMING PRESET 2-3 SECONDS MUTE 2 (M2) = TIMING ADJUSTABLE 3-30 SECONDS

MUTE 2 DELAY = USE REAR PANEL CONTROL Reference 31

DIRECT MUTING

DIRECT MUTING - Direct Muting may be accomplished by short- ing the MUTE 1 and MUTE 2 Terminals to the G Terminal through an external switch. Each time the Muting Switch is closed the cor- responding MUTE BUSS is activated.
