STEP 1. (1) INPUT
INPUT menu setup is critical for achieving a proper signal match with your source while minimizing distortion.
INPUT SELECT (mode 1-1) determines how many signal connections to the amplifier are made. If you are running
one channel (one mono RCA connection), set the amplifier's input mode to "1ch", and plug the RCA into the
left/white signal input. If you are running a stereo bass signal to the amplifier (both left and right channel RCA's),
set the amplifier's input mode to "2ch", and plug both RCA connectors into the appropriate jack. INPUT LEVEL
(mode 1-2) allows the A/D converter's input signal range to be optimized for the best possible signal clarity and
output level. Setting this overly sensitive (severely clipping the input) can result in very high distortion with musical
peaks, so use the clipping indicator as an additional guide in setting this level. If additional gain is still required,
return to this adjustment again later after continuing through the remaining setup steps.
SETTING THE INPUT
• Push "MODE" to access "1" (INPUT).
• Push "ENT" enter "1". Push "ENT" to enter "1-1" (SELECT).
• Toggle
to select "1ch" or "2ch". Push "ENT".
• Push "ENT" to enter "1-2" (INPUT LEVEL).
• Toggle
to the input level that will properly match the
source unit output to the amplifier input. Severely clipping the
input will result in high distortion, so use the clipping indicator
as a guide to set this level.
• Press "MODE" to advance to step 2 below.
STEP 2. (2) LPF (Low Pass filter)
Eliminating unwanted higher frequencies is essential for optimizing
subwoofer performance and integration with the rest of the system.
Selecting the appropriate cut off frequency of the low pass filter will
depend upon the application, so a wide frequency range (30Hz-
200Hz) is provided to choose from. Please note however, that if the
selected frequency is very close to or overlaps with the subsonic filter,
it will result in little or no output. Also, if an external crossover is
used, the internal filter can be turned off.
ADJUSTING THE CROSSOVER
• You should be in mode "2" (LPF) now from the
previous step.
• Push "ENT" to enter "2".
• Push "ENT" to enter "2-1" (ON/OFF).
• Toggle
to "ON". Push "ENT".
• Push "ENT" to enter "2-2" (FREQUENCY).
• Toggle
to desired frequency.
• Push "MODE" to advance to step 3 below.
