BX700 BASS AMPLIFIER

76-45507C 010917

  

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.
