TERMINALS AND CONNECTIONS
1. Fuse
EDB10A / EDB12A: ensure a 20 amp fuse is fitted, never fit a fuse with a rating higher than 20
amps.
EDB12TA: ensure a 25 amp fuse is fitted, never fit a fuse with a rating higher than 25 amps.
2. Power Input Terminals
See Power Connections on Page 4 for more details
3. Power/protection LED’s
When the amplifier is wired and installed correctly the green LED on the amplifier heatsink will
illuminate to indicate the amplifier is operating correctly.
If the amplifier is incorrectly wired or an abnormal situation occurs such as speaker cables shorting
the red protection LED will illuminate.
4. Crossover frequency control
This will allow you to set the frequency at which the amplifiers low pass filter will take affect. This is
variable from 50 – 250 Hz. 50 Hz will produce only low frequencies (deep bass), 250 Hz will produce
low and higher, more punchy bass response.
5. Bass boost
This will allow you to boost the bass at a frequency of 45 Hz and is variable from 0 – 12dB
Please note – by bo12dB you are asking the amplifier to work 8 times harder.
6. Gain control
Used to match the input signal of the headunit to the amplifier. See the setup section for more
details. Please note – the gain control is not a volume control it is a level match.
7. Low level input / RCA Cables
For connection to any source with a low level output. Connect this to the RCA outputs on your head
unit.
Please take extra care when running RCA cables from the source to the amplifier. Ensure that they
are placed away from all items that can generate any interference, wiring harnesses etc.
It is recommended that the RCA cables should be run on opposite sides of the car to the previously
installed power cables if possible, to avoid the cable picking up interference.
8. High level input
For connection to a source unit without low level outputs. Connect this to the front or rear speaker
wires of the headunit ensuring that the polarity (positive and negative) is correct.
