LIMIT (orange LED)

It indicates the Overload Limiter circuit is on.

Caution:

When this led is on (although sporadically), it means the applied load is a hard one. The activation of Overload Limiter circuit (output power limiter) will anyway allow the amplifier to function without distortions. In case Overload Limiter gets on too frequently (at every power peak), you will need to check if there are any failures or a too hard load (that’s to say impedance is about 50% lower than the minimum recommended one). The amplifier can go on functioning in these conditions but power will inevitably decrease.

CONFIGURATIONS

CONFIGURATIONS TABLE

LRx 4.300 can be configured as follows:

Config. 1 = Front (Hi 12 dB) + Sub: (Lo 12/24 dB); IN A (1 IN) – Pre Out (Hi 12 dB)
