Front Panel
Pan control [PAN]
The pan pot control assigns the
fader output signal of each input
channel to the Stereo Left and
Right mixing busses. At the de-
tented center position, the pan
pot routes the signal equally to
the L and R mixing busses. Pan-
ning from one side to the other
gradually assigns the input signal
to either the stereo L or R mixing
busses exclusively.
Effects Control [EFF]
This
control
determines
the
amount of post-fader/post-EQ sig-
nal assigned to the effect buss
from a given input channel, and
thus the level of effects for that
channel.
Low Equalizer Control [LOW]
The low EQ control alters the low
frequency response of the input
channel, providing ±15dB at
20Hz of continuously variable ac-
tive shelving equalization. The
"0" detented position provides
flat audio response.
High Equalizer Control [HIGH]
The high EQ control alters the
high frequency response of the
input channel, providing ±15dB
at 20kHz of continuously variable
active shelving equalization: The
"0" detented position provides
flat audio response.
Input Channel Level [LEVEL]
The level control provides con-
tinuously variable adjustment of
the channel output to the Stereo
Left and Right mixing busses,
thus determining the level of that
channel in the main sound sys-
tem mix. The nominal level of the
input level control is at the "0"dB
position.

Cross-fade Control for Reverb/ Effect
[REV/EFF X-FADE]
When this control is in the center
position, the REV RET and EFF
RET signals are equally assigned
to the stereo mixing buss. Rotat-
ing the control counter-clockwise
decreases the EFF RET signal
level, keeping the original level of
the REV RET signal. Rotating the
control clockwise decreases the
REV RET signal level, keeping the
original level of the EFF RET
signal.
Headphone Jack [PHONES]
The headphone jack will accept
any stereo headphone with 8
ohms impedance, or higher. This
jack provides the same signal as
the Stereo output L and R.

Level Control for Reverb/Effect
[REV/EFF LEVEL]
This control governs the amount
of reverb signal (built-in or out-
board) through the reverb return
jack (REV RET), and effect signal
returned through the effect return
jack (EFF RET) to the system
mixing buss. The signals of REV
RET and EFF RET are controlled
simultaneously.
Stereo Level Control
[STEREO LEVEL]
These concentric controls deter-
mine the overall level of the
Stereo L & R output (STEREO
OUT L and R).
System Level Control
[SYSTEM LEVEL]
This control determines the over-
all level of the KD-2 system.
Power/Protect LED Indicator
[POWER/PROTECT]
The LED indicator lights red and
remains lit for 3 seconds after the
power switch has been turned on,
and then turns to green when the
KD-2 is powered up. The LED
lights red when the protection
circuit is activated.
Power Amp Compression
Indicator [COMP]
The Comp LED lights when the
internal compressor is activated.
The compressor is provided to
protect the speaker system by
compressing the input signal
level of the power amplifier when
clipping occurs in the output
stage. Frequent flashing of the
LED is not reason for alarm.
However, a constant or steady
light indicates that the KD-2 is
being overdriven and that the
internal power amplifier is poss-
ibly "under powered" for that ap-
plication. The output level of the
KD-2 should be decreased until
the LED only flashes intermittent-
ly.
