VECTOR AMPLIFIER
1. LIMIT LED
The Limit LED will light when the D-CAT amplifier output signal exceeds the
maximum output point. The internal limiter in the D-CAT amplifier will limit
the output signal at the point of clipping and will not allow the amplifier to
go into distortion. If the Limit light flashes on transients, it indicates that
the limiter is being activated on the peaks of transients. This light will also
light and remain on if the amplifier reaches the point of thermal protection.
Once the amplifier cools, the Limit light will go out and the amplifier will
become active.
2. POWER LED
This red LED indicates that the amplifier is on and active.
3. SUB LEVEL
The SUB LEVEL adjusts the output level of the VECTOR internal subwoofer.
