4. Internal Balance Jumpers – The default setting here is the ideal configu-
ration. However, just like Pale Ales, there’s a lot of variation from car to car
and install to install. On the rare occasion you have noise that the Ground
Isolation option didn’t resolve, you can remove the top two screws on each
side panel and remove the lid and change these jumpers from Balanced to
Unbalanced or some combo thereof.
5. Trigger mode – Having options for getting turned on is always a nice
thing. Accordingly, the Trigger Mode switch provides you with three ways
to set up your turn on mode for The Epicenter Micro:
Remote in – When set to this turn on mode, The Epicenter Micro will only
turn on when 12 volts DC is applied to the Rmt (remote) jack
GTO – the Great Turn On™ setting will turn The Epicenter Micro on when
the factory system is on. This circuit senses when the factory amp stage is
active. Super convenient!
Audio – Setting the Trigger Mode to Audio will turn on The Epicenter
Micro when actual audio signal is sensed at the input stage – either at the
speaker level or line level inputs.
6. Ground Isolation – On the rare occasion that you can hear the brakes or
blinkers or the windshield wipers through your stereo, then you should
start here first for some easy troubleshooting. Switching this option around
should get rid of noise issues in typical set ups. The default position at the
ISO position is for the best but your mileage may vary.
7. PFM – As we’ve noted before, best be careful with this one. Leaving it to ON
and proper gain staging will ensure your subs will live a long life. Bypassing
the PFM may shorten the life of your fine sub depending on it’s frequency
handling capabilities. The PFM filters the lowest frequencies below 20Hz
which you can’t hear anyway, but if these ultra-low frequencies are present
and run through the electron garden of bass enhancement that is The
Epicenter Micro, you can do some serious damage to a sub. So, careful.
8. Output Voltage – This setting maximizes the bass performance of the
signal while making sure it doesn’t exceed some nominal voltage output.
The Epicenter Micro will make prodigious bass from the thinnest of signals
so you’ll want to make sure the downstream signal processor or amp can
handle the voltages that this puppy can offer. Check the specs & do some
reading - if that downstream device isn’t an AudioControl processor or
amp, it may not have the best performance with that immense sub signal
voltage that The Epicenter Micro will produce.
9. Power Terminal Block – You’ll hook up your power, ground, and trigger in
and outs here:
Ground – You’re a pro, have great style, you know what you’re doing
with wiring up grounds and know that a good grounding scheme means
unwanted noises. Running your ground wire directly to the negative
on the battery is best but attaching to the chassis where there is good
ground path is perfectly sufficient as well.
+12V – Connect your +12V to a constant to the positive battery terminal.
RMT IN – This is for a 12V trigger source or a switched 12V from a head unit.
RMT OUT – Run this to your amp’s 12V trigger or remote input.
10. ParaBASS® – The ParaBASS controls allow you to shape The Epicenter bass
restoration effect to your specific application and vehicle acoustics. The
Sweep control allows you to select a center frequency (the frequency most
affected) between 27 and 63 Hz. The Wide control allows you to control
the shape of the filter centered around the Sweep frequency.
11. Bass Maximizer LED – This little yellow LED dances when The Epicenter
Micro is doing its job - maximizing bass. How much or how little the LED
dances depends on input level from the source. Adjustments to the Bass
Maximizer effect from the ACR-4 (outer knob) will have no affect on this LED.
12. Output – Connect these RCAs to your amp and turn it up!
