Installation; Installation Considerations - Rockford Fosgate Power Elite T20001bd Installation And Operation Manual

7. Remote Bass – The Para-Punch Remote Bass connection is made with a RJ-45 cable and can be installed
in a variety of ways for easy control access. One control is used to boost low frequency information to
overcome road noise and put the bass in your face.This Bass control is a narrow band adjustment
variable from 0dB to +18dB with a Gyrator based Punch EQ that eliminates frequency shift with boost.
The other control is used for adjusting center frequency variable from 35Hz to 70Hz.
8. Infrasonic Filter – A 28Hz High Pass filter designed to prevent frequencies below the audio range
from being applied to the subwoofer from the amplifier. Consequently improving subwoofer
performance and power handling, particularly in vented enclosures.
9. Gain Control – The input gain control is preset to match the output of most source units. It can be
adjusted to match output levels from a variety of source units.
10. Variable Crossover – Is a built-in 24dB/octave Butterworth filter with a crossover point variable
from 32Hz to 250Hz.The crossover is set to Low-Pass (LP).
11. Mode Switch – Used to set the amplifier between single, for single amplifier use, and Master or Slave
for when connecting multiple bd amplifiers together.The first amplifier in the series being set as
Master and the subsequent amplifiers being set as Slave.This allows one gain, crossover, infrasonic
filter and bass boost setting for all slaved amplifiers.
12. Phase Switch – Used when bridging two bd amplifiers together using a bd Sync cable to phase one
amplifier 180° from the other when driving a common load.
13. bd Sync Connection – These amplifiers have a 6 pin mini DIN connector.When operating two
amplifiers together in a bridged mode, a bd Sync cable must be used.This will allow the two
independent frequency carrier generators in each unit to be synchronized.
14. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level input.
They are nickel-plated to resist the signal degradation caused by corrosion.
15. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisy-chaining an additional
amplifier without running an extra set of RCA cables from the front of the vehicle to the rear amplifier
location.
16. Remote Terminal – This heavy duty, platinum-plated wire connector will accept wire sizes from
12 AWG to 24 AWG.This terminal is used to remotely turn-on and turn-off the amplifier when
+12V DC is applied.
17. Power Terminals – The power and ground connectors on the amplifier are platinum-plated and will
accommodate up to 1/0 AWG wire maximizing the input current capability of the amplifier.
