REAR PANEL FEATURES
1. AUDIO INPUTS
a. Connect to Unbalanced Female RCA Inputs.
b. Connect to the Right Female RCA input from a LFE output connection on a receiver or pre-amp processor.
NOTE: If not using an LFE connection, both inputs have been calibrated to the same sensitivity level and
should be connected. When connecting to a stereo pre-amp connection, use a Y-Adapter when connecting
2. SETUP MODES
a. BOUNDARY EQ – Select the appropriate setting based on these guidelines below.
b. PHASE – Factory-set at 0°, adjustable to 180°. The phase of the subwoofer can be adjusted to fine tune
the signal coincidence of the subwoofer and the lower frequencies of your speakers. Adjust the phase, listening
for an increase in mid bass in the crossover region.
c. CROSS-OVER – Crossover frequency setting of the Low Pass Filter. Factory-set at 80Hz.
Each EA-AMP-SUB-1D-500 has the capability to be adjusted from 40 to 160Hz.
d. Boundary EQ – Removes exaggerated boomy sounds created by corner loading, large wall surfaces,
or installations inside custom cabinetry. For a natural, tighter performance in less than ideal installation
circumstances where boundaries are influencing the sound desired, select the ON position to compensate.
For all other installations, or for when the exaggerated boomy sound is desired, leave the boundary switch
in the OFF position.
3. POWER MODES
a. ON – Always On
b. AUTO – On, triggered via signal sense; when signal is off, amp will stay on for approximately
15 to 20
minutes.
c. TRIGGERED – On, triggered by 12 VDC, 100mA minimum. NOTE – Use the 1/8˝ mono mini-jack to connect
a 12 volt trigger wire from other devices. Connector polarity is tip positive.
