JENSEN Power Amplifier Owner’s Manual

JENSEN Power Amplifier Owner’s Manual

Preparation

Please read entire manual before installation. Due to the technical nature of amplifiers, it is highly recommended that your 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 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 as 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 (no more than 36″ or 1 meter). 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 signals deliver the best performance. If unavailable, use the high level inputs – when interfacing with factory head unit for instance.

Power / Protect Indicators

• Colored LED indicators illuminate from the plastic power terminal.
• The blue LED illuminates during normal operation (POWER) and the red
  LED indicator is visible when the amplifier detects a fault (PROTECT).

CAUTION

• Do not use both low and high level inputs at the same time. Connect only one or the other.
• Keep low level inputs away from any power wires to avoid engine noise.
•  Never run any wires underneath or outside the vehicle.

Amplifier Connections

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

• 2 Speakers (stereo)
  
  Typical Stereo Wiring (2 ohms minimum)

• Speakers (bridged)
  
  Typical Bridged Wiring (4 ohms minimum)
  (Typical 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.

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

Controller App Download/Installation

Scan the above QR Code to download the Jensen Octane DSP Amplifier Controller app from the Apple App Store or Google Play Store onto your smartphone or tablet.

Use the app to control features including: X-Over, EQ, RGB Light Customization, Volume and other amp settings directly from your smartphone or tablet via Bluetooth.

Note:
XDA amp series do not support audio streaming and hands free calls via Bluetooth

Bluetooth Pairing with App and AMP

• Step 1 : Touch the BT icon
• Step 2 : Touch the Scan icon to search the Bluetooth amp.
• Step 3 : Bluetooth amp list to show what amp is paired. (If only one amp is installed, one amp model number is displayed.)
• Step 4 : Select the amp model number you want to install from the device list
• Step 5 : Touch the drop down Icon to show the version number of App and amp and to see if the Bluetooth paring is completed successfully
• Step 6 : Touch Disconnect to disconnect the amp from the App.

JENSEN DSP AMP App Operation

Input level Control (Master Level at HOME Mode)

|

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.

---|---

X-OVER Mode (XDA92RB and XDA94RB

| 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.

X-OVER Mode (XDA91RB)

| XDA91RB (Mono) amp works only with LPF.
X-OVER 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!
EQ Presets|

Select between the following EQ presets : Classic, Pop, Rock, Jazz, Custom (allows user to enter custom EQ settings).

Custom EQ

| Custom EQ from EQ Presets is selected to make the customized audio settings and each gain per frequency can be adjusted at EQ Mode of the App.
RGB Color|

It allows the amp illumination to be turned off or on at RGB mode of the App. One color or multiple colors can be controlled.
