5.1.1: MONO INPUT CONTROLS
PHANTOM POWER 48V
Apply a DC voltage of 48V to all microphone inputs
This button is found on the right of the console near the headphones level control, not on the channel strip.
With phantom power on, you should use only balanced sources in the console's XLR microphone inputs. Balanced
dynamic microphones (for example) will be unaected. Condenser microphones normally require phantom
power, and it is sometimes used to power active circuitry in other devices, such as DI boxes.
LIMITER
Activate the input limiter
The Signature's dbx® Limiters uses fixed time constants and threshold with high-ratio compression to tame signal
peaks and prevent audio clipping. You can purposefully 'drive' the limiter by turning up the Gain until the limiter
LED lights. The Limiter button LED lights when gain reduction is applied.
GAIN REDUCTION LED
Lights when the Limiter is applying gain reduction
When the Limiter applies gain reduction, the LED will light. The LED’s light will become more intense as more gain
reduction is applied.
HI-Z
Switch the line (Jack) input to 'Hi-Z' (high impedance) mode
Activating Hi-Z presents a much higher load impedance to the source in order to work more eectively with
high-impedance sources such as guitar, bass, and other instrument pick-ups that are connected directly to the
console. Using the ‘standard Z’ mode on high impedance sources will have a detrimental eect on the high
frequency response.
GAIN
Adjust the input gain
The Gain range is -5dB to +58dB. It is advisable to listen and/or to check the channel Peak LED while increasing
gain to avoid distortion due to clipping. Before plugging in a new source, turn the Gain down to avoid sudden
loud noises.
