WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level. It is very important to verify
that your receiver Sub-Out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the
individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may appear to have a weak
output, it may sound noisy or distorted, and the Auto On/Off feature may not operate properly.
Note: The volume can also be adjusted via the volume buttons on the front panel of the amplifier. These buttons have the same effect as
pressing the up and down volume buttons on your remote.
• PRESETS — There are four presets, consisting of Movies, R&B – Rock, Jazz – Classical, and Games. As a preset is chosen, the
preset is shown on the numeric LED as P1 for preset 1, P2 for preset 2, etc. The presets provide the following characteristics for
bass reproduction:
Movies: Maximum output and impact for explosions and other action adventure movie content.
R&B – Rock: Provides the driving bass found in today’s rock music.
Jazz – Classical: The tightest, cleanest, lowest distortion bass. The flattest frequency response of the four presets.
Games: Maximum loudness available for the impact of video games.
Each preset has its own characteristics with respect to subsonic filter, volume differential and a single contour equalizer in order to
optimize the listening mode for the preset.
