Congratulations!
And thank you for choosing this EMPHASER EA13000SPL class-D mono amplifier! To maximize the performance of this amplifier and your car audio system install, we recommend that you acquaint yourself thoroughly with all capabilities and features of this EMPHASER amp model. Please read this manual carefully, before attempting the installation and retain this manual and your purchasing / installation receipts for future reference.
IMPORTANT NOTICE:
In case you are installing your EMPHASER amplifier by yourself, you should have your installation checked and approved by an authorized professional EMPHASER dealer/installer, in order to qualify for full warranty protection and also, to reach maximum power-output and audio performance possible with your individual car audio system.
1. DESIGN FEATURES
CAR AUDIO AMPLIFIER: This EMPHASER class-D amplifier allows the cross-over controlled amplification of subwoofer systems.
DASH-MOUNT REMOTE LOWPASS LEVEL CONTROL: A compact „lowpass-level“ remote control unit can be mounted close to the drivers seat. This control device allows the convenient level adjustment of the bass volume.
DIGITAL AMPLIFICATION: This EMPHASER amplifier features an extremely efficient class-D circuitry layout, to guarantee excellent sonic performance and very high power output.
4 / 2 / 1 OHM LOAD STABILITY: This EMPHASER amplifier works totally stable into impe- dance loads down to 1.0 ohms. The high damping factor guarantees full control over the connected subwoofer system.
INTEGRATED ELECTRONIC CROSSOVER: The internal crossover section features fully variable subsonic and lowpass filters with crossover slope rates of 24/24 dB/octave.
VARIABLE PHASE-SHIFT: This amplifier features a variable phase-shift control option, that allows to adjust the output signal from 0 to 180°.
MASTER – SLAVE CONFIGURATION: Two EA13000SPL can be connected together, to obtain an ultra high output power twin-amp configuration.
UNCOMPROMISING DESIGN AND CONSTRUCTION: Only best electrical and electronic components have been used for the assembly of this amplifier line. Such as double-sided glass-fiber epoxy circuit boards equipped with high current TR output devices.
ADVANCED PROTECTION CIRCUITRY: The protection circuitry safe-guards the amplifier from short-circuits at the speaker outputs, DC offset voltage at the outputs and overheating of power electronics.
STATUS AND PROTECTION LED’S: A green and a red LED located at input the side panel enable you to monitor the operating status of your EMPHASER amp.
ADJUSTABLE INPUT SENSITIVITY: Each RCA line-input pair accepts input voltages from 300mV to 7V, providing a good match with the line-output levels of almost any head-unit on the market.

2.3 SPEAKER IMPEDANCE & POWER WIRE INFO
The heat dissipation capacity of this amplifier has been designed to cope with very low impedance loads. However, EMPHASER laboratories recommend to stay at or above the suggested impedance ratings listed below:
EA13000SPL 2 x EA13000SPL in Master/Slave configuration
Note: EMPHASER laboratories recommend a minimum main power cable cross-section (5m total length) of 50 mm², when the amp is intended to be operated at full output power for prolonged periods of time. These recommendations guarantee trouble-free operation of your amplifier, giving you full power output.
1 ohms mono
2 ohms mono
3. AMPLIFIER MOUNTING
Attention! For your own safety, disconnect the positive battery terminal (+12V) or remove the main fuse in the positive power cable near the car battery, before you start any wiring work!
Before you proceed to install this EMPHASER amplifier, it is recommended to map out the complete audio system and the respective wiring required. Consider all additional electrical requirements and accessories, such as power cables, interconnect cables etc., to complete this install. Please note that
- because of possible interference problems with the existing car electrics and electronics - especially the routing of the signal cables and the chassis ground connection will have a profound impact on the trouble-free (noise free!) operation of the amplifier.
The mounting location should be carefully selected and in the interest of passive driver and passenger safety, the amplifier must be securely mounted. Make sure that there is no wiring harness, fuel tank etc. behind or below the mounting surface, that may be damaged by the drilling of the holes for the amplifier mounting screws. After installation, there should be a clearance of at least 5cm to all sides including the top of the amplifier heatsink. Make sure the unit is not exposed to direct sunlight, humid ity, water, oil or spill of other fluids that may enter the amplifier.
-
Once the location where the amplifier will be mounted is defined, use the unit as a template for the marking of the mounting holes with pencil or felt-tip marker. The mounting holes should be pilot-drilled, using a 2,5mm or 3mm drill bit. For the actual mounting, always use the supplied rubber washers before attaching the amp to the panel with the supplied mounting screws.
Important! There must not be a direct contact of the amplifier heatsink, bottom panel or other metal parts to the vehicle chassis ground! Electrical ground-loops can result in audible hum!
4. WIRE ROUTING
4.1 MAIN POWER WIRES
Run the positive main power cable („+12 V“) directly from the positive terminal of the car battery to the amplifier. For protection of your car audio system against electrical fire hazards, resulting from a short-circuit of the main power cable to chassis ground a main fuse holder must be inserted within the first 30 cm of the positive main power cable. The applicable fuse value must be matched to the limitations of your main power cable AND the current draw of the amplifier – there fore choose an appropriate fuse value. Attach the ground cable to the amplifier. In most cases it will be best to keep the ground cable („-12V“) as short as possible, i.e. to find a chassis contact very close to the amplifier. The ground power wire must have the same cross-section as the positive power cable. The contact point where the ground wire is attached to, must be solid and clean, i.e. free from rust or paint! Tighten both power input terminals of the amplifier, and double check for perfect fit of both main cable leads!
4.2 RCA & REMOTE WIRES
Carefully run the audio signal interconnects, the amp remote wire and – if applicable - the cable of the low pass level remote control from the head-unit or dashboard to the amplifier. As mentioned before, the audio signal cables should always be routed completely separate from the power cables. Connect the remote (turn on/turn off) lead to the respective input terminal of the amplifier and to the remote output of your head-unit. Now you can connect the RCA interconnects to the respective outputs of your head-unit and to the inputs of the amplifier. The remote low pass level remote control unit can be mounted in any convenient position where it can be reached while you drive in your car.

4.3 LOUDSPEAKER WIRES
Once the speaker cables have been routed, turn loose the screws of the speaker terminal binding posts and – after inserting the stripped speaker cables – re-tighten the screws. When baring wires for connection, remove approximately 6-8mm of the insulation and after axially twisting the wires, insert the bare ends into the corresponding speaker terminal output on the amplifier.
Close the electrical circuit by inserting the main fuse. Now switch on your head unit. The green OPERATING LED of the amplifier should light up. If the LED lights up red, your installation is wrong! Immediately turn off your head-unit and carefully re-check all installation steps!
