HELPFUL HINTS
1) NO SOUND:
The MUTE function has been inadvertently engaged. Speakers have been improperly connected.
Effect Loop has been improperly connected.
2)NO HIGH FREQUENCIES: (BR510N, BR515N and external cabinets) The HIGH FREQUENCY ATTENUATION control is set low or OFF.
The HF driver may have been damaged from too much power or distortion.
3)AMP SEEMS VERY SENSITIVE ON INPUT SIGNALS:
The drive control is turned all the way up.
The active switch may need to be turned on.
4) DIR XLR HUM:
Try switching the rear GND LIFT switch IN or OUT. Check for noise from external effects or bad cabling.
5) POOR BASS FROM MULTIPLE ENCLOSURES:
Make sure the internal speaker wiring of each cabinet is correct for phase ( +/- ).
6) FOR MAXIMUM OUTPUT:
To get more output, use multiple speakers or enclosures. Every time you double your speakers, your acoustic output goes up by a factor of four. Load the amplifier down to its lowest minimum impedance for maximum RMS power.
* If you are using less than 4 ohms, be sure to set the 2 OHM SWITCH on the back of the BX500. If you go below the minimum load, your amp will shut off and go into the “protect” mode. To reset, turn your amp off and connect the recommended load or set the 2 OHM SWITCH.
SPEAKON® cables are recommended for your BX500 because of their high current capacity. While standard 1/4” speaker cables will work, 12 GA SPEAKON® cables will allow higher currents to pass through the cable to extract every watt from your amp.
The BX500 is a powerful amplifier. As with any amplifier, make sure your speakers are suitable for the available wattage. Driving speakers with too much wattage will cause them to distort and eventually fail. If distorted sound is coming from the speakers, reduce the volume until the distortion stops.

CARVIN ENGINEERING DATA BX500 / BR510N / BR515N / BASS AMPLIFIERS OPERATING MANUAL
BX500
The BX Series Bass Amplifier Heads offer classic natural bass tone with unprecedented tonal control and extended headroom. The BX500 delivers 300w at 8 ohms and 500w at 4ohms or
2ohms, yet weighs in at only 5 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 BX500 also features 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 less heat. Light weight, solid design, bullet-proof construction and a list of indispensable features assure the BX500 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.
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, 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.
Hopefully, this will help you get started. Have fun exploring the features and sounds of the BX500. Take the time with your new amp to realize it’s full potential.
