device.

sound-shaping features.

1.1 The Design Concept

Over the past few years, ﬂexibility has become important. Bass

For connection to the mains use the enclosed power cord with cold

connector which complies with the relevant safety regulations.

players must now offer a broad range of sounds and play in differ-

ent venues: home studios, professional studios, and live concerts.

Additionally, the world of electric bass playing has changed. New

effects devices and basses, with ﬁve or six strings, are launched

all the time. There is also the desire to create one’s own, “unique”

sound—which can only be achieved with innovative ampliﬁers.

Please make sure that all devices are properly grounded.

For your own safety, never remove or disable the ground

conductors from the devices or on the power cords. The

unit must always be connected to the mains outlet with

a protective grounding connection.

In response to these dual needs (ﬂexibility and individuality), the

BVT4500H/5500H offers you:

Please ensure that only qualiﬁed personnel install and

operate the BVT4500H/BVT5500H. During installation

and operation the user must have sufﬁcient electrical

contact to earth. Electrostatic charges might affect the

operation of the unit.

= TONE and GRAPHIC EQ features—for shaping and reﬁning

sound.

= VTC (Virtual Tube Circuitry)—adding the warmth of vintage

tube circuitry to sound.

= Jacks for connecting the BVT4500H/5500H to effects pro-

cessors, mixers/recording units, other preamps, and other

power amps.

WARNING!

Extreme output volumes may damage your hearing and/

or your loudspeakers. Turn down all volume and level

controls before you switch on the unit. Always set the

volume to an appropriate level.

= 2 types of speaker jacks: ¼" TS and compatible with Neutrik

Speakon connectors.

2. Front panel

Fig. 2.1: BVT4500H front panel

Fig. 2.2: BVT5500H front panel

This section describes how to use the front panel of the BVT4500H

and the BVT5500H, illustrated on the previous page and above.

{8} GAIN control: Use this control to boost or cut the level of the

input signal.

{1} POWER switch: Use the POWER switch to turn on your

BVT4500H/5500H. The POWER switch should always be

in the “Off” position when you are about to connect your unit

to the wall socket or disconnect it.

{9} PEAK LED: At various points in the signal path, the BVT

monitors the level of the audio signal. When the level is too

high, the PEAK LED warns that clipping can occur.

If the LED:

Switch-on thumps can damage your hearing and your

speakers. Before you connect the BVT to the mains,

ensure that it is turned off.

= occasionally illuminates, the BVT clips only some peaks in the

audio signal. Occasional clipping does not reduce the sound

quality and shows that the signal is strong enough.

= never illuminates, the BVT does not clip any signal peaks in

the audio signal. The audio signal is probably too weak to

make use of the full dynamic range. Increase the GAIN {8}

setting until the PEAK LED lights up only occasionally, at the

strongest signal peaks.

{2} VTC LED: When the BVT is off, this LED is not illuminated.

When it is on, this LED is illuminated and indicates that the

amp is activated for use. VTC is BEHRINGER’s analog tech-

nology that emulates the warmth of vintage tube circuitry.

INPUT features

= constantly illuminates, the BVT clips a large part of the audio

signal and you will hear a distortion. Lower the GAIN setting

and check for extreme fader or control settings.

To input an audio signal to the BVT, use features {3} - {7}, as

follows:

{3} 0 dB jack: To connect an electric bass to the BVT, use this ¼"

mono jack (unbalanced). Basses with active pickups create

high-level signals.

TONE features

“Tone” refers to the presence and quality of these frequency bands

of an audio signal:

If your bass includes an active pickup and you work with:

= bass: from 30 to 200 Hz

= the BVT4500H, use the PAD button {4} to reduce the input

= mid-range: from 200 to 2 000 Hz

= treble: from 2 000 Hz to 20 kHz

audio signal.

= the BVT5500H, use the -15 dB jack {5}instead of the 0 dB

jack.

The BVT offers controls to effectively tailor the sounds to your

needs by cutting or boosting speciﬁc bands. To adjust the tone,

use features (10) - (13), as follows:

{4} PAD button (BVT4500H only): If the PEAK LED {9} con-

stantly illuminates and the GAIN control {8} is set to 0 (zero),

the input level of the audio signal is too high. In this case,

press this button to activate the pad. The pad reduces the

input sensitivity by 15 dB.

(10) VOICING control (BVT5500H only): To select the tone you

want, turn this knob to one of the following presets.

The BVT5500H equalizes the audio signal for you.

= 1: Prominent bass and treble tones (scooped mids).

= 2: Smooth and warm treble tones (passive tone).

= 3: Flat, natural bass tones (no equalization).

= 4: Bright treble tones.

{5} -15 dB jack (BVT5500H only): To connect an active bass to

the BVT5500H, use this ¼" mono jack (unbalanced). Using

this jack will give you a lower input sensitivity as compared

with the 0 dB jack.

{6} MUTE button (BVT5500H only): Use this button if you want

to tune a bass without hearing the tone. This feature mutes

the main signal path, but not the TUNER output.

= 5: Flat, natural bass tones that are not muddy (bass rolloff).

(11) - (13)BASS, MID, and TREBLE controls: For each tone

(bass, mid-range, and treble) that you can emphasize or

de-emphasize, the BVT includes a single TONE control.

{7} OVERDRIVE button (BVT5500H only): Use this button to

add a distorted texture to the audio signal. This feature

“overdrives” the BVT5500H preamp.

ULTRABASS BVT4500H/BVT5500H

To emphasize a tone, you can turn the relevant tone control

toward 10 (maximum boost). Alternatively, you might con-

sider lowering adjacent bands. To de-emphasize a tone,

you can turn the relevant tone control toward 0 (maximum

cut).

(16) LEVEL fader (BVT5500H only): To compensate possible

level changes of the equalized signal, slide this control

between +12 and -12. At “0” level, the BVT5500H neither

boosts nor cuts the equalized signal.

(17) EFFECTS MIX control (BVT5500H only): If you created an

effects loop, use this control to adjust the dry-wet mix.

When you choose to cut rather than boost an audio

signal, you protect audio equipment from high signal

levels (clipping) and preserve valuable headroom.

As you turn this control toward:

= 0 (zero), you hear more of the dry signal (without effects). At

zero, you hear only the dry signal.

GRAPHIC EQ features

= 10, you hear more of the wet signal (effects). At 10, you hear

With the TONE controls ((10) - (13)) discussed above, you em-

phasize and de-emphasize three fairly wide frequency bands.

However, with the GRAPHIC EQ features, you can emphasize

and de-emphasize 9 more narrow frequency bands. This lets you

reﬁne the sound that you created with the TONE controls. The

GRAPHIC EQ features include (14)-(16):

only the wet signal.

For details about creating an effects loop, see 3. REAR PANEL

((29) - (30)).

MASTER features

(18) MASTER control: To adjust the speaker volume and the

level of the PREAMP OUTPUT, turn this control toward 0 (no

volume/level) or, alternatively 10 (maximum volume/level).

(14) EQ ON button: To turn graphic EQ and level features, push

this button.

(15) EQ faders: If you activated the frequency-band faders (14),

you can use each one to emphasize and de-emphasize

a speciﬁc frequency band. The center frequency of each

frequency band is displayed directly above the relevant

fader.

(19) LIMITER button: The limiter reduces only the signal peaks

that can overdrive the POWER AMP and distort the audio

signal. The limiter prevents the BVT4500H/5500H from

clipping these signal peaks. To activate or alternatively

deactivate the limiter, push this button.

To emphasize (boost) a frequency band, slide the relevant

fader up. Alternatively, slide the faders for the surrounding

frequency bands down.

Because high signal peaks can damage loudspeakers, it

is recommended to activate the limiter and not to play at

full volume for a long time without ear protection.

To de-emphasize (cut) a frequency band, slide the relevant

fader down.Alternatively, slide the faders for the surrounding

frequency bands up.

(20) LIMIT LED: When the limiter is activated, this LED is

illuminated.

Cutting rather than boosting a frequency band protects

audio equipment from high signal levels (clipping) and

preserves valuable headroom.

3. Rear panel

Fig. 3.1: BVT4500H/BVT5500H rear panel

This chapter describes how to use the rear panel of the BVT4500H

and the BVT5500H, which includes the same features. Figure 3.1

illustrates these features.

Do not block the ventilation openings that cover the

fan.

PARALLEL SPEAKER OUTPUT

To effectively use the jacks on the rear panel, you need

to know about the BVT signal path. For details, refer to

the secion “THE SIGNAL PATH”.

Via the following jacks, you can simultaneously connect up to 3

speakers directly to the BVT:

(25) Two ¼" TS (mono, unbalanced) jacks.

(21) Serial number: To register your unit, you will need this unique

(26) A single Neutrik Speakon compatible jack, for high-power

loudspeakers. The pin designation of the speaker is

pins 1+ and 1-. For details, refer to the chapter “AUDIO

CONNECTORS”.

identiﬁer.

(22) Fuse compartment: For details about the appropriate fuse

type, refer to the “SPECIFICATIONS”. See also chapter

1.1.2. Replace this fuse only with the type speciﬁed for your

country.

If you use a single speaker or a high-power speaker, connect

this speaker to the Neutrik Speakon compatible jack. To prevent

electrical shock and ensure the correct polarity, this jack locks an

audio plug in place.

(23) Power connector: To power the BVT4500H/5500H, plug the

power cord in thisAC connector. The power cord comes with

the BVT.

Before you connect speakers to the BVT4500H/5500H,

turn it off.

Attention: The POWER switch does not fully discon-

nect the unit from the mains. Unplug the power cord

completely when the unit is not used for prolonged

periods of time.

(24) Fan: This fan prevents the BVT4500H/5500H from

overheating.

ULTRABASS BVT4500H/BVT5500H

Your speaker cabinets should have a sufﬁcient power

rating (BVT4500H: > 450 W, BVT5500H: > 550 W) and

preferably a total impedance of 4 Ω or higher. Too high

a load impedance will decrease the output power rat-

ing of the power stage. For details, refer to the chapter

“ABOUT SPEAKER IMPEDANCE”.

4. About speaker impedance

The total impedance of the speakers that you connect to the

BVT affects the power output of the BVT. The minimum speaker

impedance is 4 Ω. When the total load is 4 Ω, the BVT supplies

the optimal power.

(27) POWER AMP INPUT: To connect an external preampliﬁer

How to calculate the speaker impedance

to the BVT, use this ¼" TS jack.

When using more than one speaker and each connecting to an-

other BVT speaker jack, the speakers are connected in parallel.

To calculate the resulting total impedance of the speakers, use

the following formula—

(28) PREAMP OUTPUT: To connect an external power ampliﬁer

to the BVT, use this ¼" TS jack.

EFFECTS LOOP jacks

To connect the BVT4500H/5500H to an effects processor you can

use one or, alternatively both of these jacks ((29)- (30)). Keep in

mind that the BVT4500H and the BVT5500H do not process effects

in the same way. For details, see “THE SIGNAL PATH”.

—where Z₁, Z₂etc. are each the impedance of a single speaker

and Z_totalis the resulting impedance of all speakers.

(29) RETURN jack: To send an audio signal from an effects

processor to the BVT, use this ¼" TS jack.

For two speakers (Z₁and Z₂), the formula reads as:

(30) SEND jack: To send an audio signal from the BVT to an

effects processor, use this ¼" TS jack.

Z₁⋅ Z₂

Z₁+ Z₂

Z_total

LINE OUTPUT features

To send an audio signal from the BVT to a mixer or a recording

unit, use the LINE OUTPUT features ((31) - (34)), as follows:

Via the formula, you get a 4 Ω load with:

= one 4 Ω speaker

(31) LEVEL control: To adjust the level of any LINE OUTPUT,

turn this knob toward min (no level) or, alternatively max.

= two 8 Ω speakers

The value of the max setting depends on what you selected via

the PRE/POST button (33). If you selected:

= one 8 Ω speaker and two 16 Ω speakers

As the speaker impedance decreases, the output power

of the BVT increases. High output power can damage

your speakers. As the speaker impedance increases,

the output power of the BVT decreases.

= PRE: max is ~ 0 dB.

= POST: max is ~ 10 dB.

(32) GND LIFT button: To manage the ground connection be-

tween the BVT and a mixer/recording unit, use this button.

When this button is:

= pushed out, you maintain a ground connection that prevents

electrostatic charges from interfering with an audio signal.

= pushed in, you break the ground connection. Do this only when

ground-loop hum interferes with an audio signal.

(33) PRE/POST button: To select the type of signal you want to

send to a mixer/recording unit, use this button.

When this button is:

= pushed out (PRE EQ and effects), the BVT does not apply any

preamp features (TONE/EQ/EFFECTS) to the audio signal.

= pushed in (POST EQ and effects), the BVT applies all preamp

features to the audio signal.

For details, see “THE SIGNAL PATH”.

(34) BALANCED OUTPUT: To connect the BVT to the mic input

on a mixer or, alternatively to a recording unit, use this XLR

jack (balanced).

Before you connect the BVT4500H/5500H to mic input

on a mixer, turn off the phantom power on the relevant

channel of the mixer.

(35) TUNER OUT jack: To connect the BVT4500H/5500H to an

electronic tuner, use this ¼" TS jack.

To tune while muting the PARALLEL SPEAKER OUTPUTs, do

one of the following. If you work with:

= the BVT4500H, turn the MASTER control to 0 (minimum

setting).

Alternatively, you can use the tuner’s mute feature: Connect

EFFECTS SEND (30) to the tuner input and EFFECTS RE-

TURN (29) to the tuner output. When you:

= activate the mute feature on the tuner, the tuner does not

send the audio signal to the RETURN jack.

= deactivate the mute feature on the tuner, the tuner sends

the audio signal to the RETURN jack. The audio signal

follows the signal path to the PARALLEL SPEAKER

OUTPUTs.

= the BVT5500H, activate the mute feature {6}.

5. Setup example

6. The signal path

The following illustration provides an example of how to set up

the BVT5500H.

This section provides what you need to know to effectively use

the BVT control elements and connection jacks. For an overview

of the possible paths your signal may take, refer to the illustration

in the section “SYSTEM BLOCK DIAGRAM”.

In general, the signal path of the BVT can be split into two

phases:

1) Pre-Ampliﬁcation, which starts at the INPUT jack ({3},{5})

and ends immediately at the PREAMP OUTPUT jack (28).

2) Power ampliﬁcation, which starts at the POWER AMP IN

jack (27)and ends at the PARALLEL SPEAKER OUTPUT

jacks ((25),(26)).

Note that only the PARALLEL SPEAKER OUTPUTs carry a

fully ampliﬁed signal while the other output jacks carry line-level

signals.

The rest of this section covers all BVT jacks and ways to connect

your equipment to them.

You can select the type of preampliﬁed signal (PRE or POST

TONE/EQ/EFFECTS) that the BVT5500H sends. For details, see

“THE SIGNAL PATH”.

Notice that the LINE OUTPUT jack (with POST) derives the signal

before the MASTER control. This means the output level of this

jack is independent of the actual ampliﬁer volume.

Keep in mind that you can activate and deactivate the EQ sec-

tion. In addition, the BVT4500H and BVT5500H do not process

external effects in the same way. For details, see the section
