1. Power LED
Lights when power is turned on.
2. Output level control
Adjusts output level.
3. Tweeter level control
Adjusts tweeter level within a +/- 3dB range.
4. Low-frequency EQ control
Adjusts low frequency characteristics (around 55Hz
range) within a +/- 2dB range.
5. Unbalanced input terminal (Phone jack)
Accepts -10dBV unbalanced input.
6. Balanced input terminal (XLR-3-31 type)
Accepts +4dBu balanced input (hot pin is #2).
<CAUTION>:
The balanced (XLR) and the unbalanced
(phone) input connectors cannot be used simultaneously.
When the unbalanced connector is plugged, the unbalanced
input takes priority and the balanced input is disabled.

This LO FREQ switch permits
c o r r e c t i o n o f t h e l o w f r e -
quency (around 55Hz range)
response by +/- 2dB.
This control is factory-set the
"0" position. By setting the
switch at the "+2dB" position,
the 55Hz response will be en-
hanced. Setting to the "-2dB",
the response will be attenu-
ated by 2dB.
