Features and Setup
Attenuation Control Security Plate
The Attenuation control security plate
Attach the plate, after making final adjustments to the Attenuation controls, by sliding the tabs into the two installation slots. Secure in place with the
attachment screw.
Setting the Mode Switches
The CMX 2000V has mode switches for STEREO, PARALLEL INPUTS, or BRIDGE MONO modes. Each channel has independent clip limiting and low
frequency filtering.
Clip Limiter
What it is
When the audio signal drives the amp's output circuit beyond its power capability, it clips, flattening the peaks of the waveform. The clip limiter de-
tects this and reduces the gain to minimize the amount of overdrive. To preserve as much of the program dynamics as possible, limiting reduces the
average program level until peaks barely clip.
The limiter only responds to actual clipping, and automatically compensates for load and voltage variations. Each channel has its own clip limiter, and
you can switch it on or off independently, as shown in
When to use it (or not)
When driving full-range speakers, clip limiting reduces high-frequency distortion caused by bass overloads. It also protects higher frequency drivers
from excess overdrive and harsh clipping harmonics.
When driving subwoofers, some users let the amplifier clip without limiting because it gives extra "punch" to kick drums and similar sounds.
CWUSNORG: Nn bi‑amplifier systems, excessive limiting will affect the frequency balance.
