AQ-AD300.2
TEST & TUNE
1. Select the desired mode for the crossover mode switch; ‘LP’ for
low-pass mode or ‘HP’ for full-range mode (default).
Setting the gain
With the system functioning properly, follow these steps to set the gain control:
1. Turn the gain control(s) all the way down (counter-clockwise).
2. Turn the key to the accessory position, and then turn the source unit on.
3. Set all tone (bass, treble) and equalization controls (balance, fade) on the source
unit to “flat” or “0”, and turn off “loud” or “loudness”. If a separate equalizer is used, dis-
able or set all of it’s controls to “flat” or “0”.
4. While playing a standard non-MP3 CD
1
, set the source unit’s volume control to
75% of maximum level.
5. Slowly increase to gain control until you hear a slight distortion
of the audio playback. This should result in the typical range.
Setting the gain too high in an attempt to get “more volume” can not only cause premature
distortion, but can also damage your speakers. If your system configuration results in your
gain control being set outside the typical range as indicated above, call Aquatic AV to resolve
the problem.
3. While playing a standard non-MP3 CD
1
, set the crossover filter
adjust to the desired frequency (default is 150Hz or above).
Note1: this is the preferred audio testing source method, as MP3, XM, FM, and am all have some level of com-
pression or degradation involved, which can lead to varying results. If the preferred method is not available, use
the most common playback method you will use.
2. Set all tone (bass, treble) and equalization controls (balance,
fade) on the source unit to “flat” or “0”, and turn off “loud” or “loud-
ness”. If a separate equalizer is used, disable or set all of it’s con-
trols to “flat” or “0”.
