2.4 SPEAKER IMPEDANCES & WIRE INFO

The heat dissipation capacity of this amplifier has been designed to cope with low impedance loads. However, EMPHASER laboratories recommend staying at or above the suggested impedance ratings listed below:

EA1500FLX → 2 ohms mono

2 x EA1500FLX in Master/Slave configuration: 4 ohms mono

Note: EMPHASER laboratory recommends a minimum main power cable cross-section (5m total length) of minimum 25mm^2 and 35 mm^2 , when the amp is intended to be operated at full output power for prolonged periods of time. To reduce the diameter down to 25 mm^2 , please use an according power distribution block.

These recommendations guarantee trouble-free operation of your amplifier, giving you full power output.

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 a 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 on all sides including the top of the amplifier heatsink. Make sure the unit is not exposed to direct sunlight, humidity, 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 2,5 mm or 3 mm drill bit. Make sure that the housing of the amp does not come into electrical contact with the vehicle.

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's detachable power terminal. 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 – therefore choose an appropriate fuse value.

Attach the ground cable to the amplifier's detachable power terminal. 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!

Before connecting the detachable plug to the amplifier, tighten both power input terminals of the plug, 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 REMOTE & LOUDSPEAKER WIRES

Once the remote and speaker cables have been routed, turn loose the screws of the detachable speaker terminal and – after inserting the stripped remote and 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 detachable plug. At least connect the detachable terminal to the amplifier.

Close the electrical circuit by inserting the main fuse. Now switch on your head unit. The blue OPERATING LED of the remote control panel 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!

5. CrossoVer adJustMents

5.1 LOWPASS CROSSOVER FREQUENCY ADJUSTMENT

Note: Before you attempt to adjust the lowpass crossover frequency, you must set the subsonic highpass filter to its lowest position (10 Hz).

The LOWPASS cut-off frequency setting depends on some variables. As a rule of thumb, settings in a range between 60 to 90 Hz will render best sonic results. If you use this amp for SPL scores, it is advisable to set the lowpass crossover frequency above 80Hz.

Note: In general, setting the lowpass crossover frequency too low, will result in a weak and muddy sounding bass, while setting this crossover frequency too high will result in a 'booming' bass sound and reduced low end extension.

5.2 SUBSONIC HIGHPASS CROSSOVER FREQUENCY ADJUSTMENT

Adjust the SUBSONIC potentiometer according to your needs. This setting depends on the dimension and the power handling of the installed subwoofer system. The higher the subsonic crossover frequency is set, the higher the mechanical power handling of the connected subwoofer system will be. The trade-off is reduced low end extension! The subsonic highpass can not be bypassed! But you can set the SUBSONIC control to its lowest position at 10 Hz, which will not longer impose an audible effect to the music played.

5.3 INPUT LEVEL ADJUSTMENT

To reach a maximum in dynamic response from each individual head-unit/amplifier/speaker combination, it is important to set the respective input level controls („GAIN“) of this amplifier correctly.

Before you start, you MUST set all tone controls (Bass, Mid, Treble, Loudness etc.) and the fader on the head unit to their neutral or center positions.

Now turn the input gain controls of the installed amplifier anti-clockwise to its minimum position. Set the volume control of your head-unit to approximately 34 of full volume, while playing a dynamic piece of music. Slowly increase the input gain control by turning the GAIN control clockwise until you can just about hear distorted sounds coming out of your subwoofer system. Reduce the main volume level on your head-unit to a medium listening level.
