INSTALLATION EXPERIENCE

Installation of your PowerBass equalizer requires detailed knowledge of electronics wiring and proper installation skills. We strongly recommend installation by an authorized PowerBass dealer. This Owners Manual only provides general installation and operation instructions. If you have any reservations about your installation skills, please contact your local PowerBass dealer for assistance.

INSTALLATION PRECAUTIONS

NOTE: Proceed only if you are a qualified installer, otherwise; see your authorized Powerbass Dealer to professionally install this amplifier. Always wear protective eyewear when using tools.

Turn off all stereo and other electrical devices before you begin.
Disconnect the negative (-) lead from your vehicles battery.
Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the install.
Check the mounting depth to make sure there is sufficient room around the EQ.
When connecting ground points, make sure all paint is carefully scrapped away from the auto body and contact is made with bare metal.
Use a utility knife to trim away fabric from hole locations before drilling or cutting.
When running power cables through sheet metal, be sure to use grommets to properly insulate the metal edges from the wire insulation.
If possible, use tubing through grommets.

MOUNTING THE EQUALIZER

There are two basic mounting options for your PowerBass equalizer. One is to mount the unit under the dash with the supplied brackets as shown above:

The other option is to cut a hole through a suitable panel in the dash for a built-in look. If you choose the in-dash mounting method, be careful to cut the right size hole for the best appearance. Also take care not to let your EQ and/or its cables interfere with other in-dash components.
Some dash kit manufacturers make a special kit for some vehicle models that will allow the installation of the EQ with a DIN size head unit. Check with your local PowerBass dealer for additional information.

PowerBass Xtreme Multi-Zone Equalizer XEQ-4BT Description

The PowerBass is engineered to deliver superior sound quality and versatility. Its seven-band graphic equalizer allows users to tweak the bass, midrange, and treble frequencies to their liking, ensuring an optimal listening experience. The device is well-suited for both amateur and professional audio setups due to its user-friendly interface and robust build. The multi-zone capability makes it particularly useful in environments where different areas require different sound settings, such as in large homes or commercial spaces.

WIRING CONFIGURATIONS

USING MAIN INPUT

As you may have already guessed, there are numerous ways to configure your PowerBass EQ into your audio system. Spending a little time planning out your system will yield the most satisfying results. The following diagrams are just a few of the possibilities:

NOTE: If you are using a source unit that does not have RCA or 3.5mm output (low level) jacks, a optional Line Level (High/Low) Converter must be connected between the speaker output (high level) leads and the XEQ-4BT. Direct connection of high level (speaker) outputs to the XEQ-4BT will damage the source unit.

USING AUX INPUT

Set SOURCE INPUT control knob to AUX.

USING ONLY BLUETOOTH

Set SOURCE INPUT control knob to BT (BLUETOOTH).

TURNING ON THE POWER
The XEQ-4BT has internal ON/OFF circuitry which responds to turning ON or OFF the ignition or head unit (radio) of your car audio system. This requires that your head unit have a remote turn on lead available on the rear panel (which most aftermarket radios have). When not using an aftermarket head unit connect to the vehicles accessory or ignition wire that provides a switched output.

With this convenient remote turn-on/off feature, you never have to worry about turning off the power to the equalizer when you shut off the audio system.

EQUALIZATION ADJUSTMENT
There are no strict rules to adhere to when setting the main equalizer controls. Common sense says to use your PowerBass EQ to make your system sound its best. However, don’t try to push your system too hard by overdriving the amplifiers and speakers resulting in damage to some of the components.

BLUETOOTH PAIRING AND OPERATION

Turn the source selector knob to BT (Bluetooth).
Go into the Bluetooth settings of your device and search for XEQ-4BT and select to pair. Once paired now you can stream audio to the XEQ-4BT.
You can use either the Bluetooth device or the XEQ-4BT to change tracks and control the master volume of your system.
There is no visual or audio conformation from the XEQ-4BT to indicate your device is paired you must con-firm this from your Bluetooth device.
There is no need to un-pair your device to listen to a different input source. Use the front panel source selec-tor knob to change MAIN or AUX input.

EQUALIZER BAND RANGES

Each knob is essentially a tone control dedicated to a specific part of the audio spectrum from 20Hz to 20kHz. They can help your speakers match the environment of your vehicles interior. There are 4 knobs for ZONE 1 and 4 knobs for ZONE 2 that allow you to adjust the EQ setting for each zone separately. Start with all nine knobs in the 12 o’clock position, listen to a variety of musical passages. By rotating each of the knobs it will become apparent which knob affects which part of the audio spectrum.

Each center frequency receives 18dB of boost and cut--rotating counter clock wise gives you the minimum boost while clockwise rotation provides the maximum boost. When it comes to music, everyone has their own particular taste. The following equalization guidelines should help you achieve the superior sound you want.

BASS (75Hz): Use this control sparingly since it can produce low bass punch but may force the speakers to reproduce sounds beyond their capability.
MID BASS (260Hz): Controls frequencies above sub bass and below the midrange.
LOWER MIDRANGE (2kHz): This range is responsible to musical instruments, vocals and midrange percussion.
TREBLE (14kHz): Considered the upper high range frequencies

Setup Guide

Setting up the PowerBass Xtreme Multi-Zone Equalizer XEQ-4BT is relatively straightforward. Here’s a step-by-step guide:

Connect the equalizer to your main audio source using the line-level inputs.
Connect the outputs to your amplifiers or speakers, ensuring each zone is properly wired.
Power on the device and adjust the settings for each zone using the independent controls.
For Bluetooth connectivity, pair your device with the equalizer by entering pairing mode and selecting the XEQ-4BT from your device's Bluetooth list.
Use the seven-band graphic equalizer to fine-tune the audio frequencies for each zone.
