CA-2A T-Type Leveling Amplifier contains the following controls:
•
Clipping LED (ProChannel only). Shows if the input signal to the CA-2A T-Type Leveling
Amplifier module is clipping. If there is any distortion in the ProChannel signal chain, the
clipping LEDs let you identify where the clipping occurs.
•
Enable/disable. Enables/disables the CA-2A T-Type Leveling Amplifier.
•
Limit/Compress. Changes the dynamic processing ratio between compressor and limiter.
The compression ratio fluctuates depending on the frequency of the incoming signal.
• Limit. In Limit mode, the compression ratio ranges between 4:1 for low frequencies and
20:1 for high frequencies. Limiting can be used in many ways, including:
•
Creating a louder or fuller sound by limiting the dynamic range and increasing the
perceived overall level of the mix.
•
Increasing the volume and density of individual instruments in the mix.
•
Preventing digital overs and other types of overload protection. Think of it as an audio
safety net that puts a cap on the overall level. A limiter is the most transparent way to
boost average level without clipping.
•
Creatively sculpting a sound's dynamics.
• Compress. In Compress mode, the compression ratio ranges between 3.5:1 for low
frequencies and 6:1 for high frequencies. This method is suitable for leveling and
reducing the general dynamic range of individual instrument tracks such as vocals and
drums. It produces a more gentle compression.
•
VU meter. The VU meter can be switched to show gain reduction or output level, depending
on the position of the VU meter mode knob.
•
VU meter mode. Switches the VU meter to show gain reduction or output level.There are
four available modes:
• GR. Displays the instantaneous gain reduction in dB. During periods of no gain
reduction, the pointer will return to 0 VU on the meter scale.
• +10. Displays the post-processing output level, referenced to +10 dBm (analog
emulation).
