T1: 0.04 to 3s
• If muting input 2 turns on outside the T1 range after muting input 1 turns on, the SL-V will not mute and
remains in normal operation. (The SL-V does not go into a lockout condition or interlock condition.)
• If only muting input 1 or muting input 2 turn OFF and back ON, the SL-V will not return to the muted
condition. To return to the muted condition, both muting inputs 1 and 2 must first turn OFF and the mut-
ing conditions must be met again.
• If the SL-V power is turned ON while either muting input 1 or 2 is on, the SL-V will not go to a muted
condition. In this case, both muting inputs must be turned OFF and the muting conditions must be met
again.
