SERVICE
The B2000 mono block bass head offers classic natural bass tone with one of
the highest powered amps in the industry. The
B2000 delivers 700w at 8Ω, 1300w
at 4Ω and 2050w at 2Ω. All this power is housed in a 2U lightweight 14lb chassis.
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 for you to carve out your signature sound. Harmonic content increases as you turn up the Drive control producing a growl at maximum settings. A 12AX7 preamp tube yeilds warm tube harmonics, which is switchable in/out of the preamp cir- cuit. Solid design, bullet-proof construction and a list of indispensable features assures
B2000 will be the heart of your rig for years to come.

GETTING STARTED QUICKLY
If you are like most players, you probably want to plug in your new amp and get started play-
ing right away. Before you start, be sure your amp is plugged into the correct AC voltage. 1. With POWER off, connect a speaker cabinet to one of the rear SPEAKER OUTPUTs. 2. Set the VOLUME and DRIVE to “0” and set the ACTIVE INPUT switch for your type of bass. 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 the output level of the bass guitar fully up. Gradually increase the amp VOLUME control to the desired level. If no sound is heard, turn down the VOLUME con- trol and check the MUTE and PROTECT LEDs. 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 LO MID control. 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 the B2000 is a powerful amp, 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.
DESIGNED FOR THE RIGORS OF TOURING
The B2000 is constructed using a heavy-duty aluminum chassis. All internal cabling is securely
tied and harnessed. Every circuit card is MIL SPEC, double-sided, through-hole plated, fire retardant FR-4 glass epoxy.
