Cleaning The Appliance; Functions (Front) - JB Systems enh2.3 Mk2 Operation Manual

ENGLISH
• When installed in a booth or flight case, please make sure to have good ventilation to improve heat
evacuation of the unit.
• To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when
bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full
performance.

CLEANING THE APPLIANCE:

Clean by wiping with a polished cloth slightly dipped with water. Avoid getting water inside the unit. Do not
use volatile liquids such as benzene or thinner which will damage the unit.

FUNCTIONS (FRONT)

1. Channel ON/OFF switch: This button switches the processor over between operation (green led is lit)
and bypass (red led is lit).. You can use this switch to compare the sound with and without processing.
This makes it easier to tune the sound using trial and error.
2. LOW MIX control: Controls the amount of low band signal, produced by the bass processor, used for
sound enhancement (from zero to maximum). The setting depends on the application and can be
adapted to your own taste. When adjusting, use the channel ON/OFF switch (1) to compare between
original and processed sound.
Important: Note that the bass processor should be used with care to avoid possible speaker damage.
Most small speakers or near-field monitors are not capable of handling the low frequencies produced by
this unit.
3. SOFT/TIGHT switch: used to select the type of bass processing.
•
SOFT = warm and full bass
•
TIGHT = dry and punchy bass (orange LED is lit)
4. TUNE control: Sets the cutoff frequency of the high-pass filter. In a range from 1kHz to 8kHz you can
select the frequencies that are routed to the high band processor.
5. PROCESSING control: this knob controls the function of the device. When turned clockwise, the Exciter
function is activated and the signal's transparency ad sharpness will be increased. When the music
already contains enough clarity and high frequencies (for example in classical music) it's better to use
the enhancer setting (turned counterclockwise)
6. HIGH MIX control: Controls the amount of signal, produced by the high band processor, used for sound
enhancement (from zero to maximum). The setting depends on the application. It can be used to give a
high-quality system the little "finishing touch" it needs or you can add some extra clarity to a relatively
poor sound system. In any case it is up to you to adapt the sound to your own taste. Always start
adjusting with the HIGH MIX control turned in counterclockwise position and use the channel ON/OFF
switch (1) often to compare between original and processed sound.
Important: Note that the high band processor should be used with care to avoid possible tweeter
damage. Improper and excessive use of high band processor can cause overload to the tweeters of your
speakers. Always start tuning the high band processor with the HIGH MIX control completely turned to
the left.
7. Surround ON/OFF switch: to switch the surround processor ON (green LED is lit) or OFF
8. Surround Level: Use this knob to make the perceived stereo image wider. The more you turn the knob
clockwise, the wider and more spacious the stereo image becomes.
9. SUB: Controls the level of the separate subwoofer output (15)
10. POWER switch: used to switch the unit ON/OFF
