Short description of operating controls
1. FULL RANGE
On (button
Œ
front, depressed):
At the FR/HI-output the high-pass filtered FULLRANGE (FR)-signal is presented. This signal is
particularly extended towards the lower frequencies.
Off (button
Œ
front, not depressed):
At the FR/HI-output the high-pass filtered HIGH (HI)-signal, preventing extreme loudspeaker
hub, is presented. This position can be applied to monitor and speech only applications or for
active sub bass extension situations.
2. MONO BASS
On (button
•
front, depressed):
Both BASS-outputs provide the same bass-signal in the form of a MONO-sum.
(Only when ACTIVE BASS
•
ON.)
3. BASS GAIN
Dial
Ž
with 41 indent positions and double function:
1) FULL RANGE ON
Œ
, ACTIVE BASS OFF
•
:
Stepless boosting of the extended low frequency range at the FR/HI-outputs.
Due to increased
loudspeaker hub, extreme boosting reduces the power capacity of the low-frequency driver
.
2) ACTIVE BASS ON
•
:
Volume control of the BASS-outputs of between -
∞
...+9dB. At the
REF
position both the
BASS- and FR/HI-outputs deliver equal electrical output. The complete control range allows
the matching of differing efficiencies between connected sub-bass and full-range systems
4. ACTIVE BASS
On (button
•
front, depressed):
Activates the BASS-outputs and routes the function of the BASS GAIN control to
here.
Off (button
•
front, not depressed):
The BASS-outputs are muted and the BASS GAIN control allows the stepless adjustment of
the low frequency segment at the FR/HI-outputs.
5. LOW MID EQ
Dial
•
with 41 indent positions, Flat...Max (0...+6dB):
Allows the individual boosting of the low/mid frequencies especially effective when operating
isolated single systems.
Extreme loudspeaker hub can cause damage to woofer loudspeakers
especially in combination with the extended low frequencies of the FULL RANGE mode.
6. LOW MID EQ
On (button
‘
front, depressed):
Activates dial
•
.
7. MID EQ
Dial
’
with 41 indent positions, Min...Flat (-9...0dB):
Allows the stepless cutting of the mid-range band for adjustment to individual hearing prefer-
ences and for the adaptation to given room acoustics.
8. MID EQ
On (button
“
front, depressed):
Activates dial

9. POWER
LED
shows the power status of the device.
