FRONT PANEL FEATURES
1. Level
These two knobs control the levels of Channels
1 and 2. The knobs are detented to make it easy to
set both controls to the same level. Usually, these
controls are set all the way up.
The amplifiers are designed so that a +3.4 dBu
(1.15V rms) input signal drives the amplifier to full
power into 4 ohms:
J•800 = 300 watts per channel into 4 ohms
J•1400 = 450 watts per channel into 4 ohms
J•2500 = 750 watts per channel into 4 ohms
This equates to a gain of about 30 dB (30 dB, 32 dB,
and 34 dB respectively). The graphics around the
knob indicate full gain of (about) 30 dB when the
knob is all the way up (fully clockwise).
After you have set the levels for the mixer (or
other signal source), adjust the Level controls on the
amplifier as the final adjustment to set the overall
volume for the system.
. SIG
This is short for “signal present.” These green
LEDs indicate when a signal is present after the
Level controls, at the output stage of the power
amplifier. If the Level controls are turned all the way
down (fully counterclockwise), these indicators will
not light.
3. OL
This is short for “overload.” These red LEDs
indicate when the output of the amplifier has
reached the maximum, and is right on the hairy
edge of clipping. Clipping is bad for speakers and
should be avoided.
It is okay if the OL LED blinks occasionally. It
means that the transient peaks of the music are just
hitting the full output of the amplifier.
However, if the OL (overload)
LED is blinking frequently or
continuously, turn down the source
signal (i.e., the mixer’s master
faders) or the amplifier’s Level
controls.
4. POWER
This handy switch turns the power amplifier on
and off. When the amplifier is on, the POWER LED
lights to let you know Juice is ready and rarin’ to go!
REAR PANEL FEATURES
5. Power Cord Socket
Here is where you connect the detachable power
cord that came in the box with your amplifier. Plug
the other end of the power cord into an AC outlet
properly configured with the voltage required for
your particular model.
