ENGLISH
 SE100 can be used to correct the loss of sound quality, caused by all kinds of effect
equipment. In this case put the SE100 as last unit in the chain of effect equipment.
 SE100 can be used to compensate the loss of sound definition during tape
duplication: the copy can be even better than the original! Put the SE100 between
the output of the playback deck and the input of the recording deck.
For additional information on connections please refer to the next paragraph.

CONNECTIONS
1. INPUT connector: this female XLR-connector accepts both unbalanced and
balanced line signals from the unit that needs audio enhancement.

For balanced use, please follow these conventions:
Pin1 = Ground ~ Pin2 = Hot (+) ~ Pin3 = Cold (-)
Readymade cables are available from JB Systems (ex. 7-0063 ~ 5m XLR m/f)

For unbalanced use, connect Pin3 (-) to Pin1 (ground/shield)
Readymade cables are available from JB Systems (2-0445 ~ cinch/XLR m)
2. OUTPUT connector: this male XLR-connector can be connected to both
unbalanced and balanced line inputs.

For balanced use, please follow these conventions:
Pin1 = Ground ~ Pin2 = Hot (+) ~ Pin3 = Cold (-)
Readymade cables are available from JB Systems (ex. 7-0063 ~ 5m XLR m/f)

For unbalanced use, connect Pin3 (-) to Pin1 (ground/shield)
Readymade cables are available from JB Systems (2-0440 ~ cinch/XLR f)
3. SUBWOOFER OUTPUT connector: this male XLR-connector can be connected
to both unbalanced and balanced inputs of subwoofer amplifiers. The cutoff
frequency and level of this output are adjustable.

For balanced use, please follow these conventions:
Pin1 = Ground ~ Pin2 = Hot (+) ~ Pin3 = Cold (-)
Readymade cables are available from JB Systems (ex. 7-0063 ~ 5m XLR m/f)

For unbalanced use, connect Pin3 (-) to Pin1 (ground/shield)
Readymade cables are available from JB Systems (2-0440 ~ cinch/XLR f)
4. Mains input: connect the sound enhancer to the 220V AC mains, using the
supplied power-cord.

CONTROLS AND USE
5. ACTIV switch: This button switches the processor over between operation and
bypass. When the button is pressed the blue led turns on to indicate that the
processor works. 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.
6. SHIFT switch: Sets the cutoff lower frequency of the bass processor. Depending
on the situation you can select 50Hz or 100Hz cutoff frequency for the bass
processor. This function also helps reducing system load.
7. 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 ACTIV switch to compare between original and processed
sound.
Important: Note that the bass processor should be used with care to avoid
possible speaker damage. Most smaller and economical speakers are not
capable of handling the low frequencies produced by this unit.
8. 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.
9. PROCESSOR control: controls the efficiency of the high band processor. The
signals' transparency and sharpness increases while turning the control knob in
clockwise direction. When adjusting, use the ACTIV switch to compare between
original and processed sound.
10. 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 ACTIV switch 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.
11. PHASE INVERT switch: To add more bass punch, a subwoofer can be
connected to the subwoofer output. Sometimes the conductors of the subwoofer
are inversed which results in poor sound quality with a lack of low frequencies:
the opposite of what you expected! This can be corrected by inversing the (+) and
(-) poles of the cabling to your subwoofer or ... by pushing the PHASE INVERT
