Operation and Performance
24
Several amplifiers will, under normal conditions, be able to be powered up simultaneously. If you do experience
problems powering up multiple amplifiers simultaneously, use the NomadLink network and the NLB 60E to
establish a power sequence with a pre- set delay between each amplifier’s start-up.
Front-panel monitoring and adjustments
5.6.8 Level indicators
Each channel pair of the C...X amplifier has an indicator window with five LEDs per channel plus a bridge
indicator.

LED indicators
▸ Orange CPL (Current Peak Limiter) flashing indicates signal exceeds the limits of the output devices and
limiting is in effect.
▸ Red VPL/CLIP indicates that the signal has exceeded maximum output voltage (Maximum voltage is
determined by rear-panel VPL settings).
▸ Signal / Hi-Imp (Green/Red) indicates an output signal above -44 dB. If it turns Red, this indicates that
a high impedance (“open” connection) has been detected at the output. This can be a fault such as a
disconnected cable or malfunctioning driver. However, it could indicate acceptable high impedance, such
as a sub-bass enclosure with high impedance at a certain frequency.
For more detailed signal level indications use the DeviceControl software application.
