A6600B
INITIAL SETUP
1. After opening and unpacking the A6600B equal-
izer, inspect the unit for any noticeable damage.
Though Phonic attempts to take every precau-
tion possible in preventing damage occurring to its
products in transit, it is sometimes unavoidable. If
the product is noticeably damaged, users are ad-
vised to contact the dealer at which they purchased
the product.
2. If you wish to mount the A6600B into a 19” rack, en-
sure it is not positioned above power amplifiers and
that the unit has plenty of ventilation, as to avoid
over-heating.
3. Plug any required devices into the A6600B’s inputs
and outputs. For example, a mixer’s output signal
could be sent to the inputs, and an amplifier and
speakers connected to the outputs.
. Plug the provided power cord into the power con-
nector and into an appropriate AC power source.
Be sure to check local voltage levels before con-
necting the unit. Do not under any circumstances
defeat the ground-pin of the cord, as it is provided
for your own protection.

CONNECTIONS AND CONTROLS
Front Panel
1.Output Level Meter
This 6-segment LED level meter will give you an accurate
indication of when the output level of the A6600B
equalizer reaches certain levels. If the red “Clip” LED
illuminates, users are advised to reduce the level of that
particular channel, either through use of the input level
control or by lowering the frequency slide controls.
2. FB.D Switch
The FB.D Feedback Detection System is activated
when this button is pushed. When feedback is detected,
an LED will illuminate on the affected frequency’s slide
control. Users can lower the level of that frequency to
eliminate the feedback.
3. Audio In/Out Switch
Pushing this button will enable and disable the equalizer
function for the respecting input channel. When the
equalizer is disabled, the input signal will be sent
directly to the output channel without being altered.
4. Range Switch
This switch is used to change the boost/cut range of
the frequency slide controls between ±12 dB and ±6 dB
(switch depressed).
5. Input Control
This control is used to adjust the input level for the
corresponding channel. It gives you a boost/cut range
between -1 and +1 dB.
6. Low Cut Switch/Control
The A6600B features a low-cut control that will allow
users to select the cut-off frequency of the low-cut filter
between 10 and 00 Hz. Please note that this affects
the signal sent through the subwoofer output, as well.
7. High Cut Control
The high-cut control allows users to select the cut-off
frequency of the high-cut filter between 2.5 kHz and
30 kHz. All frequencies above your selected frequency
will be cut, helping you to better define which frequen
-
cies you wish to be processed by a power amp (if one
is connected to your outputs). Setting the frequency to
30 kHz will allow the signal to pass through unaltered
by the high-cut filter.
