What is an Enhancer or Exciter
An Audio Enhancer is a multi-band processor which focuses selected high frequencies and applies specific filtering
to isolate and boost them without introducing other unwanted high frequencies, th
us giving more “sparkle” and
“liveliness” to the signal. An Audio Exciter is a processor which actively replaces missing high frequencies by
actively generating overtones based on the existing frequencies to introduce more dramatic and yet more synthetic,
high frequency content.
The Bass Processor on each channel is a device which improves phase-alignment and focus of low frequencies,
giving similar attention to the bass as the Enhancer/Exciter does for the higher frequencies.
The SURROUND PROCESSOR varies phase-alignment between CH A and CH B to give the listener the
impression that the sound is coming from increasingly different directions. This has the effect of a virtual widening of
the stereo field when CH A and CH B are used to process the left and right channels of a mix.
Connection
The
unit can be used in 2 configurations…
1. As 2 independent mono graphic enhancer/exciters
– e.g. for 2 separate microphones on channel inserts
2. As a stereo left & right processor
– e.g. as a main L+R enhancer/exciter on master inserts or between the
mixer and amplifier or recording equipment
Before connecting to an amplifier or other equipment, turn down all volume controls to avoid loud noises which may
cause damage to other equipment. Always switch amplifier power on last in line with volume levels down. Use good
quality 6.3mm jack or XLR signal leads to connect the enhancer/exciter to allied equipment. Connect mains power
via the IEC (ensuring lead is in good condition and the voltage selector is same as the supply voltage) and switch
the POWER on.
Operation
Begin with LOW MIX, HIGH MIX and SURROUND controls set fully down (anti-clockwise)
Set the TUNE control to the desired range of frequencies to be affected
– 1kHz is Mid frequencies and 8kHz is High
Begin with the PROCESS control in the centre position (equal amounts of each process)
Gradually increase HIGH MIX and check the difference in high frequency content until the desired effect is reached
Varying the TUNE control at this stage will sweep the effect through the various frequencies.
If the process sounds too dramatic or unnatural, turn the PROCESS control toward ENHANCER.
If the process is too mild or ineffective, turn the PROCESS control toward EXCITER
To process bass, switch the BASS PROCESSOR
“IN/OUT” button to IN and the respective “IN” LED will light.
Select the MODE
– SOFT suits classical and subtle music content, TIGHT suits high energy dance music
Pressing IN/OUT gives a comparison of the signal with and without the BASS PROCESSOR.
To expand the perceived stereo field, press IN/OUT until the indicator is lit and gradually increase the rotary control
Use the IN/OUT switch to compare the effected and unaffected signal until the desired amount of process is set.
