CARVIN B1000 User Manual

The B1000 Bass Amplifier Head offers classic, natural bass tone and unprecedented
tonal shaping with minimal controls and extended headroom. The B1000 delivers 325w
at 8 ohms, 600w at 4ohms and 900w at 2ohms, yet weighs only 6-1/2 pounds.
The Class A input stages produce the harmonic basis for the preamp right from the
input jack. It begins with a boutique flat response, then we add 6 tone controls specifi-
cally designed for bass guitar, allowing you to carve out your signature sound. Harmonic
content increases as you turn up the DRIVE control, producing rich growl at maximum
settings. A bypassable 12AX7 preamp tube yields warm tube harmonics. The Class D
output and lightweight switch-mode power supply use far less energy from the wall while
producing more power with less heat.
Light weight, solid design, bullet-proof construction and a list of indispensable features
assure the B1000 will be the heart of your rig for years to come.

GETTING STARTED
1. With POWER off, connect a speaker cabinet to one of the rear SPEAKER OUTPUTs.
2. Set the DRIVE and VOLUME to "0" and set the ACTIVE INPUT switch for your type of
bass. If Equipped with a battery, select ACTIVE.
3. Set all tone controls to their center "5" position. This is the "FLAT" setting for the amp.
4. Now turn the amp ON. Turn up the volume on your bass guitar. Gradually increase
the VOLUME control to the desired level. If no sound is heard, turn down the VOLUME
and check the MUTE switch, speaker connections and PROTECT LED.
5. Increasing the DRIVE control will add harmonic richness to your sound. Turning up
the DRIVE also increases volume. Re-adjust the VOLUME after adjusting the DRIVE.
6. Adjust the tone controls to your liking. Keep in mind that turning up a tone control
isn't always the answer. Sometimes turning down one of the MID controls will get you
the sound you want.
Depending on your speakers you may get more volume and clearer bass from your
cabinet by lowering the SUB BASS control and increasing the BASS or LOW MID control.
7. Need more volume? There is a limit to the amount of volume a speaker can produce,
and driving a speaker beyond its limit can damage it. Even though these are powerful
amplifiers, adding more speakers is the only way for substantially more output. Every
time you double your speakers you increase your acoustic output by a factor of four.
This guide will get you started. Have fun exploring the features and sounds of the B1000.
Take the time with your new amp to realize its full potential.
