Controls and functions
VRx1.500
ON - Green led
It indicates the amplifier is on.
SAFETY - Red led
It indicates protection intervention: excessively high
temperature or output anomalies (direct current,
short circuit or dangerously low load impedance).
Protection intervention stops the amplifier
functioning. Switch the amplifier off; when anomaly is
eliminated, switch the amplifier on again.
PEAK - Orange led
It is on when VRx amplifier is about to reach distortion
threshold. It is useful to adjust inputs sensitivity.
K1 - Bal/Unbal inputs switch.
K2 - LNS circuit ON/OFF switch for line noise
suppression.
K3 - It selects sensitivity range.
LM - Amplifier input sensitivity adjustment.
Note: In case of installations with more amplifiers
connected in cascade, we recommend to put K2 onto
ON in the first device (i.e. the one which receives the
signal from the head unit), leaving it onto OFF in the
others.
If disturbance persists, you can activate LNS anti-noise
circuit also in the other amplifiers.
