on my Emphaser EAD the relays do not pick up. when i bridge them,amp plays normal sound. Q50,51, are ok what else could. Does anyone know what kind of transistors have in outputs and power supply? I am thinking to buy one with blown outputs and fets. Search among more than user manuals and view them online

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 amplifier.
Emphaser EA 1800D
This control device allows the convenient level adjustment of the bass volume. The high damping factor guarantees ez1800d control over the connected subwoofer system. 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. 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.
Each RCA line-input pair accepts input voltages from mV to 7V, providing a good match with the line-output levels of almost any head-unit on the market. These recommendations guarantee trouble-free operation of your amplifier, giving you full power output. Consider all additional electrical requirements and accessories, such as power cables, interconnect cables etc.
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! 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.
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, humidity, water, oil or spill of other fluids that may enter ea1080d 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.
There must not be a direct contact of the amplifier heatsink, bottom panel or other metal parts sa1800d the vehicle chassis ground!
EMPHASER EAD Specifications
Electrical ground-loops can result in audible hum! 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 emphwser fuse value. Attach the ground cable 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 emphsaer to, must be solid and clean, i.
Tighten both power input terminals of the amplifier, and double check for perfect fit of both main cable leads! As mentioned before, the audio signal cables should always be routed completely separate from the power cables. 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. When baring wires for connection, remove approximately mm 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. If the LED lights up red, your ea800d is wrong!
Immediately turn off your head-unit and carefully re-check all installation steps! Before you attempt to adjust the lowpass crossover frequency, you must set the subsonic highpass filter to its lowest position 10 Hz.
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. 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 ea8100d can not be bypassed! The low pass level remote control — if installed in your system configuration – should be set at a low position, so there is enough headroom to turn enphaser the bass volume later on. Slowly increase the input gain control of the channel pair, that drives the subwoofer sby 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.

The phase-shift control enables you to match the acoustical phase relations of subwoofer and the speaker system playing in the front doors. The target is, that both speaker systems, normally separated by aprox. A good match of the acoustical phase between subwoofer and the system in the front doors will give you the impression of bass sounds coming from a place in front of you.
Or the other way round, the subwoofer playing in the trunk of your car can not be localized that easily.
The second advantage is, that the upper bass region — i. This phase adjustment can only be determined by ear, so you will need somebody to help you to obtain best phase match. To judge the effect of the phase-shift adjustment, you must sit on the drivers seat, and somebody must adjust the phase shift control knob until the sound reproduction in the bass region is best.
Furthermore, it might be necessary to invert the connection polarity of your subwoofer — and re-adjust the phase, if you can not find a proper match with the normal in-phase subwoofer connection. The amp that runs in Slave mode has its control functions deactivated — ALL settings must be done on the Master amp.
