Frequently Asked Questions - XPE4700 DUAL

How do I reset the Dual XPE4700 receiver to factory defaults?

To reset, turn off the receiver, then press and hold the Power button until the display shows 'RESET'. Use the volume knob to confirm.

How do I connect speakers to the XPE4700?

Connect each speaker to the corresponding color-coded binding posts on the rear panel. Ensure proper polarity (+/-) and that the impedance is 8 ohms minimum.

Why is there no sound from the subwoofer?

Check that the subwoofer is connected to the Subwoofer Pre-out jack. In the receiver's audio menu, enable the subwoofer output and set crossover frequency (typically 80Hz).

How do I pair a Bluetooth device?

Press the Bluetooth button on the remote or front panel until 'PAIRING' appears on the display. On your phone, select 'Dual XPE4700' from the Bluetooth list.

The remote control is not functioning. What should I do?

Replace the batteries with new AA ones. Ensure the remote sensor on the receiver is not blocked. If still not working, try resetting the remote by removing batteries and pressing all buttons for 5 seconds.

How can I improve FM radio reception?

Extend the included FM antenna fully and place it in a high position. Move the antenna away from metal objects. You may also connect an outdoor FM antenna if needed.

Can I play music from a USB flash drive?

Yes, plug a USB drive (FAT32 format) into the USB port on the front panel. Navigate using the remote to select tracks. Supported formats: MP3, WMA, FLAC.

How do I set up the audio output for a TV?

Connect the TV's HDMI ARC port to the receiver's HDMI OUT (ARC) port. On the TV, enable ARC in the audio settings. Ensure the receiver's input is set to 'TV'.

What does the 'Protect' indicator mean?

The 'Protect' mode activates if there is a short circuit or overheating. Turn off the receiver, disconnect all speakers, and let it cool for 10 minutes. Check speaker connections before restarting.

How do I clean the receiver?

Unplug the unit. Use a soft, dry cloth to gently wipe the exterior. Do not use any liquids, sprays, or abrasive cleaners. For ventilation slots, use a vacuum cleaner with a brush attachment.

LOUD & CLEAR

Preparation

Please read entire manual before installation. Due to the technical nature of amplifiers, it is highly recommended that your DUAL amplifier is installed by a professional installer or an authorized dealer.

Before You Start

• Disconnect negative battery terminal. (consult a qualified technician for instructions)
• Avoid installing the amplifier where it would be subject to high temperatures, such as from direct sunlight, or where it would be subject to dust, dirt or excessive vibration.
• Use extreme caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring.
• All amplifier installations require power, signal and speaker wires (not included).
• An amplifier installation kit (sold separately) is highly recommended to facilitate the installation. Consult your dealer for recommendations.

Mounting Location

• Choose a mounting location for the amplifier. Suggested locations include under a seat or in the trunk.
• The amplifier can be mounted horizontal (recommended) or vertical. For optimum performance, make sure to provide at least 1" of space to around all sides. Do not mount the amplifier under carpets or where airflow is restricted.
• Do not install the amplifier where it may be exposed to moisture.
• The optimum mounting location varies between vehicles. Remember to test all amplifier functions before completing the final mounting procedure.

TYPICAL MOUNTING METHOD

Connection Descriptions

NOTE

Be sure to follow specific instructions included with your amplifier installation kit (not included with this amplifier). The information below should be used a general guideline only.

Power Wire (+12V)

• Disconnect negative battery terminal before proceeding. Consult a qualified technician for instructions if you are unsure.
• Plan wire routing before cutting any wires to length. Begin by routing the power +12V wire from the battery to the amplifier location. Use a grommet when running wires through the firewall or metal openings. Avoid running the power wire near existing vehicle wiring to prevent induced noise from entering the audio system.
• Use extreme caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring.
• The +12V wire MUST be fused within 18" of the battery for protection of the vehicle's electrical system.

Ground Wire (GND)

- The amplifier ground wire should be as short as possible. Choose a clean unpainted section of metal or the vehicle chassis when attaching the ground connection. Be sure to clean the area of any dirt or grease.

Remote Turn-on Wire (REM)

- The remote turn-on wire connects to the head unit's amplifier turn-on lead or power antenna output.

Speaker Wires

• Choose adequate gauge speaker wire depending on your exact amplifier/speaker combination. Be sure to observe polarity when connecting.
• Do not ground any speaker wires or connect any speaker wires together.

Input Signal

• The amplifier's input signal connects to the head unit's low level (RCA) or high level (speaker wire) outputs.
• Low level input signal deliver the best performance. If unavailable, use the high level inputs - when interfacing with factory head unit for instance.

CAUTION

• Do not use both low and high level inputs at the same time - connect only one or the other.
• Never run any wires underneath or outside the vehicle.

Main Power Connections

Connect +12V, GND and REM wires accordingly. A suitable fuse MUST be installed on the +12V lead within 18" of the battery for protection of the vehicle's electrical system.

Fuse Rating

When replacing fuses, make sure new fuse is the correct type and amperage. Using an incorrect fuse could damage the amplifier.

Amplifier Connections

Speaker Connections

Connect speaker wires observing polarity. The minimum impedance load for the XPE2700 and XPE4700 is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The XPE2700 and XPE4700 can be wired for stereo, bridged or stereo/bridged simultaneous operation.

2 Speakers (stereo)

Subwoofer (mono)

XPE2700 speaker connections shown

Input Signal Connections

Low Level Input (RCA)

Low level (RCA) input signal is preferred for best performance. Typical trunk-mount amplifier installations require a 17-20 foot RCA cable. Most trucks and under-seat applications require a 6-9 foot RCA cable. Using twisted pair construction RCA cables will minimize noise.

High Level Input (Speaker Wire)

High level inputs should only be used when RCA outputs are not available from the head unit. Connect the head unit speaker outputs to the high level input connector as shown below. The black wire (signal reference ground) may or may not require a connection to chassis ground - depending on your particular installation.

CAUTION

Do not use both low and high level inputs at the same time - connect only one or the other.

Configuration/Setup

Input level Control	The input level control (gain) is used to obtain the best possible match between the head unit audio output and the amplifier input. Begin by turning the input level control fully counterclockwise. Next, turn up the head unit volume control around 3/4 of the way up. Adjust the input level control clockwise until audible distortion is heard, then slightly counterclockwise to provide the best match. Repeat for all input level controls.
Input Mode Switch (XPE4700)	Select 2 CH mode if the head unit only has 1 pair of RCA outputs. Plug the RCA's from the head unit into channels 1/2 or 3/4. All 4 amplifier inputs will receive a signal. NOTE: There is no fader function when using 2 CH mode. Select 4 CH mode if the head unit has 2 pairs of RCA outputs. Plug the RCA's from the head unit into channels 1/2 and 3/4.
Crossover Mode	The crossover is used to filter out frequencies above or below a certain point. Choose LPF when using the amplifier with subwoofers, HPF when using with midrange/tweeter combinations and FULL when using with coaxial-type speakers. NOTE Choose FULL when using the amplifier in stereo/bridged simultaneous mode. In this mode, passive crossovers are required. Failure to use the correct passive components may damage the amplifier and/or speakers. Consult a qualified professional for recommendations.
Crossover Frequency Control	This control allows precise adjustment of the crossover frequency.
Bass Boost	This control provides additional boost @ 45Hz when used with subwoofers. Adjust this control with caution - as improper use can damage speakers!
LED Indicator	The LED indicator illuminates blue during normal operation (POWER) and red when the amplifier detects a fault (PROTECT).
