CARVIN BX700 User Manual

The BX Series Bass Amplifier Heads offer classic natural bass tone with unprecedented
tonal control and extended headroom. The BX700 delivers 300w at 8 ohms, 550w at 4ohms
and 700w at 2ohms, yet weighs under 6 pounds.
Four discrete 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 extensive tone control
allowing you to carve out your signature sound. Harmonic content increases as you turn up
the DRIVE control producing rich harmonics at maximum settings. The BX700 also features a
12AX7 preamp tube (bypassable) to add further warmth to your sound. 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 BX700 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 MASTER volume to "0" and set the ACTIVE INPUT switch for your type
of bass. If Equipped with a battery, select ACTIVE.
3. Set the four tone controls to their center "0" position and the CONTOUR to FLAT. This is
the "FLAT" setting for the amp. For now, turn off the graphic EQ.
4. Now, turn the amp ON. Turn up the volume on your bass guitar. Gradually increase the
MASTER control to the desired level. If no sound is heard, turn down the MASTER 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 MASTER 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.
7. Need more volume? There is a limit to the amount of volume a speaker can produce and
driving a speaker beyond it's 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 BX700.
Take the time with your new amp to realize its full potential.
