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.
• This amplier is equipped with a Universal Power Supply that handles voltages from 100 V to 240 V (+/- 10%)
@ 50-60 Hz
• 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 channels. Following the input stage, the dedicated level control on each channel allows signal
attenuation from 0 dB to -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 channel output voltage and therefore also the
maximum channel output power. Four different voltage stages are available using the DIP-switches on the rear
panel.
The sophisticated output section monitors faults and generates appropriate warnings, which are displayed on
the amplier and transmitted through the NomadLink network. These alerts allow the operator to adjust system
