WARNING — To reduce

the risk of fire or electric

shock, do not expose

this appliance to rain or

moisture.

19. Exposure to extremely high noise levels may cause
permanent hearing loss. Individuals vary considerably in
susceptibility to noise-induced hearing loss, but nearly
everyone will lose some hearing if exposed to sufficiently
intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has
specified the permissible noise level exposures shown in the
following chart.

Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example

8 90 Packed garage concert

6 92

4 95 VW Bus Peace Train

3 97

2 100 Cranked psychedelic tunes

1.5 102

According to OSHA, any exposure in excess of these
permissible limits could result in some hearing loss. To
ensure against potentially dangerous exposure to high
sound pressure levels, it is recommended that all persons
exposed to equipment capable of producing high sound
pressure levels use hearing protectors while the equipment
is in operation. Ear plugs or protectors in the ear canals or
over the ears must be worn when operating the equipment
in order to prevent permanent hearing loss if exposure is in
excess of the limits set forth here.

Getting Started

The following steps will help you set up your amplifier, and get the
levels just right.

SETTINGS:

1. Be sure the amplifier’s POWER switch is off.

2. Turn down both Level controls.

3. On the rear panel, set the SUBSONIC FILTER

switch OFF and the CLIP LIMIT switch ON.

4. Determine which AMP MODE is best for your

application:

STEREO mode is the typical setup for amplifying

stereo signals. INPUT 1 is routed to CHANNEL
1 output, and INPUT 2 is routed to CHANNEL 2
output.

MONO mode is used for sending a mono signal

to both outputs, with separately adjustable level
controls. INPUT 1 is used in MONO mode (leave
INPUT 2 disconnected).

BRIDGE mode uses both outputs to double
the power to one speaker (or set of speakers).
INPUT 1 is used in BRIDGE mode (leave INPUT 2
disconnected and the B Level control turned down).

NOTE:

you should connect to the amplifier in BRIDGE
mode. See “Do the Math” in Appendix B for
information on calculating speaker impedances.

5. Set the AMP MODE switch according to your

application.

4 ohms is the minimum speaker impedance

CONNECTIONS:

1. Using balanced cables, make connections from

your mixer (or other signal source) MAIN OUT to
your amplifier’s INPUTs.

2. In STEREO mode, connect the cables from your

signal source to the amplifier’s INPUT jacks,
either XLR or 1/4” TRS.

• The XLR and TRS inputs for each channel are

wired in parallel.

• The balanced XLR inputs are wired as follows:
Pin 1 = shield (ground)

Pin 2 = hot (+)
Pin 3 = cold (–)

• The 1/4” TRS inputs are wired as follows:
Tip = hot (+)

Ring = cold (–)
Sleeve = shield (ground)

3. In MONO mode and BRIDGE mode, connect

one cable from the input source to INPUT 1, and
connect nothing to INPUT 2.

4. In STEREO and MONO modes, connect speaker
cables to the SPEAKER OUTPUTS, either the
binding posts or the Speakon® connectors.

• The binding post connectors are wired as
follows:
red = hot (+ speaker terminal)
black = cold (– speaker terminal)

• The Speakon connectors are wired as follows:
1+ = hot (+ speaker terminal)
1– = cold (– speaker terminal).

5. In BRIDGE mode, if using the binding post
outputs:

• CHANNEL 1 SPEAKER OUTPUT red post = hot
(+ speaker terminal)

• CHANNEL 2 SPEAKER OUTPUT red post =
cold (– speaker terminal)
Do not use the black terminals.

If using a Speakon connector, connect the

Speakon to the center BRIDGED connector.

• The BRIDGED Speakon connector is wired as
follows:
1+ = hot (+ speaker terminal)
2+ = cold (– speaker terminal).

6. Plug all the sound system components into
suitable AC outlets, properly grounded and
capable of delivering adequate current.

7. Make sure your signal source is powered up and
delivering signal to the amp.

8. Turn the power amplifier’s switch on. Verify that
the POWER LED lights.

9. Slowly turn up both Level controls on the
amplifier. You should hear music and see the
SIG LEDs flashing. If the OL (Overload) LEDs
are flashing, turn down either the Level controls
on the amp or the source signal’s output level
controls (i.e., master faders), until the OL LEDs
either blink occasionally or not at all.

10.

For quieter listening, it is preferable to adjust

the amp’s Level controls rather than the source
signal’s output level (unless you have the source’s
control all the way up!).

Things To Remember:

• Never plug amplifier outputs
into anything except speakers
(unless you have an outboard box
specifically designed to handle
speaker-level signals).

4

• Before making connections to an amp or

reconfiguring an amp’s routing, turn the amp’s
level controls down, turn the power off, make the
changes, turn the power back on, and then turn
the level controls back up.

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.

4

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!

2. 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.

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.

7

6. BREAKER

This is a resettable circuit breaker that monitors
the amount of current being drawn by the amplifier.
Under normal operating conditions, this should never
pop. An unusual condition may cause the breaker to
pop, such as a mains voltage surge occurring at the
same time as a peak amplifier output.

Turn the POWER switch off, and push the
BREAKER button in to reset the circuit breaker. Turn
the POWER switch back on and the amplifier should
resume normal operation. If the circuit breaker pops
again, something probably isn’t right.

• Make sure that the total impedance of the

speakers connected to the outputs is 2 ohms or
greater (per channel) in stereo mode, or 4 ohms
or greater in bridged mode.

• If the breaker pops right away, even with the

Level controls turned down and the speakers
disconnected, there may be something wrong
inside the amplifier. Refer to “Appendix A:
Service Info.”

7. SPEAKER OUTPUTS

You have two options for connecting your
speakers: binding posts and Speakon connectors.

Normally, you would use either the binding posts
or the Speakon connectors. Since the connectors
are wired in parallel (e.g., CHANNEL 1 binding
post and Speakon are in parallel, and CHANNEL 2
binding post and Speakon are in parallel), you can
connect a speaker to each connector, as long as the
total impedance per channel is two ohms or more.

• Two 8 ohm speakers in parallel equals 4 ohms.

• Two 4 ohm speakers in parallel equals 2 ohms.

See “Output Wiring” on page 11 for information
on output connection wiring.

8. INPUTS

The Juice amplifiers give you two options for
connecting the input signal — XLR input connectors
and 1/4” TRS (Tip-Ring-Sleeve) connectors. These
inputs are in parallel, and are identical, electrically
speaking. You can connect either a balanced or an
unbalanced signal here.

Since these two inputs are in parallel, you
shouldn’t connect more than one source to the
INPUT 1 or INPUT 2 jacks. However, you can use
the unused input jack as a “Thru” connector, to
daisy-chain the signal to another amplifier. See
“Input Wiring” on page 10 for information on input
connection wiring.

9. SUBSONIC FILTER

Turn this switch on to engage a low-frequency
cutoff (high-pass) filter at 30 Hz. The Juice
amplifiers can amplify signals below 20 Hz, but

most speakers can’t reproduce frequencies that
low. By engaging the SUBSONIC FILTER, you allow
the amplifier to power only the frequencies that
you can hear. In addition, this filter can remove low­frequency stage noise (footsteps) and accidental
microphone pops that could damage a loudspeaker.

10. CLIP LIMIT

The CLIP LIMIT switch is there to protect your
loudspeakers from the effects of clipping. It is
designed to be virtually transparent, meaning you
probably won’t even notice any audible difference
when the switch is turned on.

We recommend that you leave this switch on at all
times. However, if you are working at quiet levels, or
you have already placed a compressor/limiter in the
signal path, you can leave the CLIP LIMIT switch off.

11. AMP MODE

This switch determines the input signal routing
within the amplifier. For most applications, you
will use the STEREO setting. However, some
applications might be better suited for using either
the MONO or the BRIDGE setting.

STEREO: This mode accepts separate left and right
inputs (A and B), and routes them to the CHANNEL
1 and CHANNEL 2 outputs. Each channel’s Level
control adjusts the gain for its own channel.

MONO: This mode accepts a single input (INPUT

1), and routes it to both the CHANNEL 1 and
CHANNEL 2 outputs. Each channel’s Level control
adjusts the gain for its own channel.

BRIDGE:

1), and uses both amplifier outputs to double the
power to one speaker (or set of speakers). Use the
CHANNEL 1 Level control to adjust the gain (turn
the CHANNEL 2 Level control all the way down).
See “Output Wiring” on page 11 for information on
how to connect a speaker in Bridge mode.

This mode accepts a single input (INPUT

GENERAL PRECAUTIONS AND CONSIDERATIONS

Rack Mounting

The Juice amplifiers are designed to be mounted
in a standard rack. They require two rack spaces
(2U = 3.5”). They also require 15.75” depth inside
the rack, including the rear support brackets. When
designing your rack, put the heavier items at the
bottom and the lighter items toward the top.

Secure the front panel of the amplifier to the
front of the rack using four screws with soft washers
to prevent scratching the panel. In addition,
because of the weight of the amplifier, you must
secure the rear support brackets of the amplifier to
the back of the rack. You could use a support rail or

9

shelf across the back of the rack, or angle brackets

attached between the rear support rails and the
rear rails of the rack. This is recommended for all
components mounted in a rack that is going to be
moved frequently (or thrown in the back of a pickup
truck and transported down a bumpy gravel road to
that outdoor festival!).

Thermal Considerations

The Juice amplifiers are fan-cooled with two
separate fans. One fan brings cool air in from the
back and the other fan blows the warm air out
the front of the chassis. Make sure that cool air is
available at the back of the amplifier, and that there
is room in the front for the warm air to exit from the
amplifier and dissipate. If rack-mounted, make sure
the air being drawn from the rack is cool. Some rack­mounted equipment expel warm air into the rack.

When the amplifier is first turned on, the fans run
at low speed. As the power output increases and
the amp warms up, the fans gradually increase in
speed to provide additional cooling.

Input Wiring

Use a high-quality 3-conductor shielded cable
to connect the signal between the signal source
(mixing console, equalizer, etc.) and the balanced
inputs to the amplifier. If you are using unbalanced
inputs, use a high-quality 2-conductor shielded
cable. Your TAPCO Dealer can recommend a
suitable cable for your application.

When connecting a balanced signal, the
connectors are wired thusly, according to the AES
(Audio Engineering Society) standards:

XLR TRS
Hot (+) Pin 2 Tip
Cold (–) Pin 3 Ring
Shield (Gnd)

Pin 1 Shield

AC Power Considerations

Be sure the amplifier is plugged into an AC outlet
that is able to supply the specified voltage. Be sure
the AC outlet can supply enough current to allow
full power operation of all the amplifiers plugged
into it. The outlet should be a three-prong socket
that matches the power cord.

WARNING: Bypassing the
plug’s safety ground pin can be
dangerous. Don’t do it!

The AC current demand of an amplifier varies
depending on several factors, including the load
impedance, the crest factor, and the duty cycle of
the program material. Under typical conditions
reproducing rock music where musical peaks are
just below clipping, the Juice amplifiers require the
following average currents.

J•800 = 5 A
J•1400 = 7 A

J•2500 =10 A

It is recommended that a stiff supply of AC
power be used because the amplifier places high
current demands on the AC line. The more power
that is available on the line, the louder the amplifier
will play and the more peak output power will be
available for cleaner, punchier bass.

If you have more than one amplifier sharing an
AC outlet, you should avoid turning them all on at
the same time. Rather, sequence them on, one at a
time, to prevent popping the circuit breaker (due
to in-rush current).

Balanced XLR Connector

Balanced 1/4" TRS Plug

Unbalanced TS (Tip-Sleeve) lines can be
accommodated via the TRS jack. Make sure the cord
terminates with a TS plug (like a guitar plug), or if it
is a TRS plug (like a headphone plug), make sure the
ring is tied to the shield, preferably at the source.

Using the 1/4" TRS INPUT 1s a “Thru” Connector

LOOK

CLOSER

Because the XLR connector and the 1/4" TRS
connector are in parallel, you can use the 1/4" TRS
jack as a “Thru” connector to pass the input signal on
to another amplifier’s input (see Figure below).

Note: If you use an unbalanced
1/4" TS cable to daisy-chain
the TRS input jack to another
amplifier, you will unbalance the
XLR input on the Juice amplifier.
This negates the benefits
associated with balanced lines
and inputs.

Using the 1/4" TRS INPUT 1s a “Thru” Connector

Output Wiring

Use heavy gauge, stranded wire for connecting
speakers to the Speakon outputs jacks. As the
distance between the amplifier and the speakers
increases, the thickness of the wire should also
increase. Speaker wire has resistance, and when
electricity passes through a resistor, power is lost. The
thicker the wire, the less resistance it offers, and the
more power actually gets to the speaker.

The thickness of the wire is rated in gauges. Use the
chart at the right to determine the correct gauge of
wire to use according to the distance between the
speakers and the amplifier, and the impedance of
the load the amplifier is driving. This ensures that the
power lost across the speaker wire is less than 0.5 dB.

In MONO and BRIDGE modes,
INPUT 1 and INPUT 2 are
connected together in parallel.
This allows you to use INPUT 2 as a
“Thru” connector to daisy-chain the
input signal to another amplifier.

Binding Posts

When using the binding post
outputs in stereo or mono modes,
you can terminate your speaker
cables with single or double banana
plugs, spade lugs, or leave them
unterminated (bare wires): unscrew
the amp’s binding posts enough to
reveal the holes on their sides, then
insert your stripped wires (stripped
about 3/8" back) into the holes and
retighten the posts (finger tight is
fine). Be careful that no runaway
strands touch the chassis or other
terminal.

The red posts are labeled “+,”
which means positive. The black
posts are labeled “–” for negative.
You probably know the importance

of getting these correct — if one
speaker is hooked up “in phase” and
the other speaker is “out of phase,”
you’ll be “out of work.” (By the way,
although everyone says “phase” in
this situation, the correct word is
“polarity.”)

Speakons

When using the Speakon outputs in stereo or
mono modes, wire the Speakon connectors as
shown below:

Bridged Mode
Binding Posts

When using the binding posts in bridge mode,
connect the positive side of the speaker cable to
the CHANNEL 1 red (+) binding post, and connect
the negative side of the speaker cable to the
CHANNEL 2 red (+) binding post. No, that’s not a
typo. You only use the red binding posts in Bridged

mode. Do not use the black posts.

Bridged Binding Post Connection

Since bridged mode is a type of mono mode,
turning a stereo amplifier into a single channel
amplifier, use only the CHANNEL 1 input. Turn the
CHANNEL 2 level control all the way down.

Speakons

When using bridge mode, wire the Speakon
connector as follows:

Dual-Channel Connection

The BRIDGED connector has the added feature
of providing both speaker outputs on a single
connector. This allows you to use a single cable
to carry both channels from the amplifier to the
speakers.

Many speakers with Speakon connectors provide
an Input connector and a “Thru” connector for
connecting a second speaker in parallel. You can
use the Thru connector to connect the CHANNEL 2
amplifier output to the CHANNEL 2 speaker.

In stereo mode, CHANNEL 1 output is available
at Pins 1+ and 1–, and CHANNEL 2 is available at
Pins 2+ and 2– on the BRIDGED connector. Wire all
four pins in the Speakon connector, as shown below,
at both ends of the cable. For the cable connecting
the “Thru” connector to the second speaker, you
need to use a “crossover” cable that connects pins
2+ and 2– on the “Thru” connector to pins 1+ and
1– on the second speaker input end.

Appendix A: Service Information

Warranty Service

Details concerning Warranty Service are spelled
out in the Warranty section on page 19.

If you think your amplifier has a problem, please
do everything you can to confirm it before calling
for service. Doing so might save you from the
deprivation of your amplifier and the associated
suffering.

These may sound obvious to you, but here are
some things you can check. Read on.

Troubleshooting

No Power

• Our favorite question: Is it plugged in? Make sure

the AC outlet is live (check with a tester or lamp).

• Our next favorite question: Is the POWER switch

on? If not, try turning it on.

• Is the red LED next to the POWER switch

illuminated? If not, make sure the AC outlet is
live. If so, refer to “No Sound” below.

• Has the BREAKER switch popped? Try pushing

in the BREAKER switch. If it pops out again right
away, refer to “Repair” on the next page.

• The AC fuse inside the amplifier is blown. This is

not a user-serviceable part. Refer to “Repair” on
the next page to find out how to proceed.

No Sound

• Are the channel Level controls turned up? Slowly

turn them up and see if you hear anything.

• Is the signal source turned up? Make sure the

signal level from the mixing console (or whatever
device immediately precedes the amplifier) is
high enough to produce sound in the amplifier.
The SIG LEDs should be blinking to indicate that
signal is present.

• If the speakers are wired for BRIDGE mode,

make sure the AMP MODE switch is set to
BRIDGE.

• If the amplifier has gotten extremely hot, the

thermal protection circuit may have activated.
Allow the amplifier to cool down and normal
operation should resume.

• Are there fuses in the speakers, or in-line fuses

in the speaker wire? Check ‘em to see if they’re
blown.

• Make sure the speakers are working properly.

One side is way louder than the other

• Are both Level controls set to the same position?

• Check your source signal to make sure the left
and right signals are balanced.

• Are the speaker impedances matched? Different
speaker loads can cause different volume levels
on each side.

• Try switching sides: Turn off the amp, swap the
speaker cables at the amp, turn the amp back
on. If the same side is still louder, the problem
is with your speaker cabling. If the other side is
louder now, the problem is with the mixer, the
amp, or the line-level cabling.

The stereo music sounds kind of
sideways, and the bass frequencies
diminish when standing center, but get
louder as you approach one side

•

Check the polarity of the speaker cable
connections. You may have your positive and
negative reversed at one end of one speaker cable.

As soon as the music gets loud, the amp
shuts down

•

Check the OL LEDs and make sure that they are
not lighting continuously. If they are, turn down the
signal source or the Level controls on the amp.

• Can the amp breathe? The amplifier draws
its ventilation air in from the back. It needs
plenty of fresh air to stay cool. Do not block the

ventilation holes.

I hear thunder, even when the amplifier
is turned off

• It’s going to rain. Get inside quickly. Bring the
amplifier with you.

Poor sound

• Is it loud and distorted? Turn down the signal
coming from the mixer or signal source.

• Is the input connector plugged completely
into the jack? Check the speaker connections
and verify that all connections are tight and
that there are no stray strands of wire shorting
across the speaker terminals.

• If possible, listen to the signal source with
headphones plugged into the console. If it
sounds bad there, the problem is not in the
amplifier.

14

Noise/Hum

• Check the signal cable between the mixer and
the amplifier. Make sure all connections are
good and sound.

• Make sure the signal cable is not routed near
AC cables, power transformers, or other EMI­inducing devices.

• Is there a light dimmer or other SCR-based
device
Use an AC
different AC circuit.

• If possible, listen to the signal source with
headphones plugged into the console. If it
sounds noisy there, the problem is not in the
amplifier.

Do The Math: Ohms, Loads, and Such

An ohm is a unit of resistance — the more ohms,
the more resistance (or, more accurately in this case,
impedance). The more the resistance, the less the
power.

If you’re dealing with just one speaker (or cabinet)
per output, the load in ohms is usually printed on it
somewhere. That’s your load, usually 8 ohms or 4
ohms.

If you’re driving an assortment of speakers,
things can get complicated. There are two basic
ways of linking multiple loads (or speakers in this
case): series and parallel.

Since series connections are not normally used
in PA applications, we’ll concentrate on the parallel
connection. Parallel means that the positive amp
output connects to the positive terminals of all the
speakers, and the negative amp output connects
to the negative terminals of all the speakers. If one

speaker fails in a parallel configuration, the others
will still work.

Calculating parallel loads is easy, as long as
each speaker has the same value — just divide the
value by the number of speakers. For instance, four
8-ohm speakers, connected in parallel, will equal 2
ohms (8/4 = 2). If the loads are not all the same, the
formula gets a little more complicated, but nothing
that you can’t do with a simple calculator.

Using this formula, an 8-ohm speaker and a 4­ohm speaker, connected in parallel, will equal 2.7
ohms. Remember that the Juice amplifiers require
2 ohms or greater per channel in Stereo or Mono
mode, and 4 ohms or greater in Bridge mode.
