5. Operation and performance
5.1. Introduction
The following sections provide comprehensive information on amplier connection, setup, operation, and
performance. The detailed information included here is essential to realizing the full functionality of the C Series
ampliers.
5.2. Operation precautions
• Make sure that the Power switch and the Remote switch on the amplier front-panel are set to “off” before
making any input, output or network connections, and also before manipulating the DIP-switches on the
rear-panel.
• Make sure that the AC mains voltage is correct and matches the voltage printed on the rear-panel of the
amplier (115 V or 230 V).
• Make sure that no signal is present at the input to the amplier when powering up. This could produce an
unintentionally loud initial volume from the speakers.
5.3. Signal flow and headroom
5.3.1. Signal flow blocks
All C Series ampliers have the same signal ow and feature set. The only difference is the amplier’s maximum
output current per channel.
The input stage of all C Series ampliers has a high sensitivity to provide ample system headroom. This in effect
means that the input stage is almost impossible to clip.
Overall amplier input gain is adjusted using the input stage DIP-switches. Please note that the gain setting is
global, affecting all four channels. Following the input stage, the dedicated level control on each channel allows
signal attenuation from 0 dB to minus innity.
The CPL (Current Peak Limiter) section dynamically limits the input signal based on three parameters: sensed
current level, feedback from the output stage, and sensed voltage clip from the VPL (and output amplier voltage
clip if “Soft Clip” activated). This ensures that power output is maintained within the design limits of the amplier.
The adjustable VPL (Voltage Peak Limiter) sets the maximum output voltage and therefore also the maximum
output power. Eight (8) different voltage stages are available using the DIP-switches on the rear-panel. See table in
Appendix section with VPL ratings at typical loads.
The sophisticated output section monitors faults and generates appropriate warnings, which are displayed on
the amplier front-panel and transmitted through the NomadLink network. These alerts allow the operator to
