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 t
o 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 on the Surround Processor 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.
