There are several differences between the two but of primary concern are power cord and
fuse values. Models with power cords containing the standard North American three prong
plug are for use with 120VAC where models with the European CEE-7 plugs are for 230V.
The following chart shows what fuse values to use for each model:

FUSE SELECTION

There are two versions of the F150 amplifier. A 120 Volt AC version for those countries
supplying 120 and a 230 Volt version for others.

RECEIVING INSPECTION

CONGRA TULATIONS!

You made a wise decision in buying a Carvin F150 amplifier. Not only did you get a refer-

ence quality amplifier but also one with the clarity and power professionals require.

QUICK SET UP

Like most new owners, you’re probably in a hurry to plug in your F150 and audition it.

Here are some brief instructions to get you going quickly.

CONNECTING AC POWER

Use only a grounded (3 prong) power outlet to avoid shock hazard.

INPUT CONNECTIONS

Balanced XLR and 1/4” phone input connec­tors are located on the rear panel and labeled
“INPUT1 & INPUT2”. The 1/4” phone jacks
can be used with either balanced (ring-, tip+,
sleeve gnd) or unbalanced (tip, sleeve) plugs.

BRIDGE INPUT

CONNECTING SPEAKERS:
STEREO MODE

Along with standard 1/4” phone jacks there
are binding posts located within a box on the
rear panel labeled “SPEAKERS”.

BRIDGE MONO MODE

This power amplifier can be converted
from stereo to mono, providing twice the
power capacity of a single channel, by
switching into BRIDGE MONO mode and
connecting the speakers to the two RED
binding posts.

When the rear panel switch labeled BRIDGE is set to its ‘out’ position, the amplifier is con-

figured for normal STEREO operation.

When the rear panel switch labeled BRIDGE is set to its ‘in’ position, the amplifier is setup
for BRIDGE MONO operation. This causes channel 2’s outputs to be “out of phase” from
channel 1’s. In this configuration a single set of speakers is connected with one lead going to
channel 1’s RED binding post and the other lead going to channel 2’s RED binding post.
(See the “Typical Bridge Mono Triamp” illustration on page 6.)

When ‘bridging’ an amp, the impedance capacity is always reduced in half. For example;
since the F150’s outputs are rated for a minimum of 4Ω per channel, the lowest impedance
allowed in bridge mode is 8Ω. (Note: Operating the amplifier with loads below the rated
minimum will cause premature distortion.)

EQ EXPAND SWITCH

This switch, when set to its ‘in’ position will boost the highs and lows by +4dB at 80Hz and
12kHz. This works well as a loudness contour when operating at low volume levels or adds
flavor when using it in a bass or guitar rack. When set to the ‘out’ position it provides a flat
output response. Try it both ways and set as desired.

POWER-UP SEQUENCE

Follow these simple steps when applying power to the system.

1. Verify all system connections while power is still off.

2. Lower all power amplifier level controls to minimum.

3. Apply power to the mixers, processors etc. first.

4. Apply power to the power amplifiers last.

5. Setup mixer, processors etc. to nominal operating levels.

6. Set power amplifier level controls to desired volume.

Note: Reverse this procedure for power-down.

Try connecting one speak­er system at a time.

Turn down the output level
of equipment feeding the
amplifier. If the sound
level is too low then raise
the controls on the front of
the power amp.

Make sure both the front
and rear of the amplifier
has adequate space for
ventilation.

Verify that the total speak­er load is not less than 4Ω
(i.e., three 8Ω speakers
per channel is less than
4Ω total.)

Check for shorted speaker
cables.

Move “BRIDGE MONO”
switch to the Stereo posi­tion.

CorrectionProblem Possible Cause

TECHNICAL ASSISTANCE

If the above chart has not been able to guide you to the problem then answer the follow-

ing five questions:

1. AC cord attached to a source ‘alive’ with appropriate Voltage and current capacity?

2. Is the fuse OK and power switched on?

CorrectionProblem Possible Cause

IN CASE OF TROUBLE

Every F150 amplifier undergoes severe environmental “burn-in” as well as thorough com-

puter controlled and human testing. It is unlikely a malfunction will occur. However, when

something doesn’t seem to work properly, please refer to the following chart:

The following diagram illustrates the typical stereo setup. Although it shows XLR’s for
inputs and 1/4” phone plugs for outputs, a variety of alternative connectors are available
(see the following sections on “INPUT CONNECTIONS” and “OUTPUT CONNECTIONS”).

INPUT CONNECTIONS

The preferred method of connecting input signals is with balanced XLR’s (two conductors
plus a shield wire, such as Carvin’s XLR8). Balanced input signals provide the highest gain
and best noise rejection. 1/4” phone jacks are also capable of providing balanced input by
using a stereo plug (ring-, tip+ & sleeve gnd). However, not all sources provide balanced
outputs. In these cases an unbalanced 1/4” input is recommended (single conductor plus a
shield wire, such as Carvin’s SH2 or SH15).

OUTPUT CONNECTIONS

There are two 1/4” phone jacks available for speaker connections (one for each channel).
Additionally, there are two pairs of binding posts that not only allow for high current con­nections to speakers but are also used when “bridging” the outputs (see section titled
“Bridging the Amp”).

Make sure to use heavy gauge wire for all speaker connections (no lighter than 16 gauge
up to 50’, like Carvin’s PH50). Caution: never use shielded cable (i.e., guitar cable) to
connect speakers. It poses an abnormal load on any audio power amplifier and its imped­ance will not provide an adequate current path for the speakers.

TYPICAL LOUDSPEAKER IMPEDANCE CONFIGURATIONS

Individual speakers or speaker cabinet wiring examples.

This is called biamping (when separating the highs and lows) or triamping (when separating
the highs, mids and lows.) The F150 power amplifier is well suited for this application. The
following sections illustrate a few possible configurations. By following the concepts present­ed here, you should be able to tailor a system to fit your needs.

STEREO BIAMP SYSTEM

The illustration at the top of page 6 demonstrates the use of a Carvin XC3000 active

crossover, an F300 amplifier for lows and an F150 for highs in a biamp system.

By moving the speaker’s Biamp switch (if so equipped) to the Biamp position, the user is
able to feed power directly into the horn through the Hi’s input and into the woofer/mid
through the Lows input.

STEREO TRIAMP SYSTEM

The illustration on the following page demonstrates the use of a Carvin XC3000 active

crossover, F600 amplifier for lows, F300 for mids and F150 for the highs.

By moving the speaker Biamp switch to the Biamp position, the user is able to feed power
directly into the horn through the High input and into the woofer/mid through the Low input.
This time the speaker’s woofer/mid combination is actually only reproducing the mid frequen­cies. The lows are then fed to the sub-woofer whose crossover selector switch is in the
Bypass position.

BRIDGING THE AMP

Carvin’s F150 amplifiers can be operated in bridged mode if you need a high power mono
(single channel) amplifier.

Speaker connections must be made on the two RED binding posts. The channel 1 RED
binding post is the positive output while channel 2’s RED post is negative.

BIAMPING AND TRIAMPING

It is desirable in many circumstances to bypass the speaker’s passive crossover network
and power the individual drivers through an active crossover.

REPLACEMENT P ART GUIDE

The rear panel switch labeled “BRIDGE MONO” must be set to the ‘in’ position. The out-

put level is controlled by channel 1’s level control (the channel 2 level control is disabled).

When ‘bridging’ an amp, the impedance capacity is always reduced in half. For example;
since the F150’s outputs are rated for a minimum of 4Ω per channel, the lowest impedance
allowed in bridge mode is 8Ω. (Note: Operating the amplifier with loads below the rated
minimum will cause premature distortion.)
