SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE

BOLTAR / COLOSSUS PRO / JUPITER

General:

At this point you are ready to get more specific on the settings for your amplifier.

X-OVER:

-When in HP operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set your FILTER FREQUENCY at cuts off all frequencies from reproduction below

this point. EXAMPLE: If you adjust the FILTER FREQUENCY to 100Hz, the amplifier will not play frequencies below 100Hz but will play frequencies from 100Hz to the highest frequency the amplifier

is capable of reproducing.

-When in FULL, all frequencies are sent to your speakers for reproduction.

-When in LP-BP operation, this setting acts as a high frequency cut off for your system reproduction. The point that you set your FILTER FREQUENCY at cuts off all frequencies from reproduction

above this point. EXAMPLE: If you adjust the FILTER FREQUENCY to 400Hz, the amplifier will not play frequencies above 400Hz but will play frequencies from 400Hz down to the lowest frequency.

PARAMETRIC EQ:

Used for fine tunning the boost enhancements in your system. Select the FREQUENCY you want to be the focus of your enhancement. Then select the range above and below this center frequency

you want to enhance using the Narrow to Wide adjustment. Your final adjustment is determining the amount of Cut or Boost you plan at the given frequency and range selected.

PHASE:

The PHASE adjustment allows for tweaking of time alignment which is an advanced Sound Quality feature. Leaving these levels at 0 will allow for standard stereo imaging.

Level Control Setup:

Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the head unit

volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input sensitivities properly to the

head unit output signal level.

It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual.

If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts.

If you are not sure what the Radio output sensitivity is, follow these general guide lines:

Turn the level control up slowly, till you hear distortion, then back off a few degrees on the control. If at any point your amplifier goes into protection, you will need to turn the Level to

the left a bit and then try again. If you reach a point where the output does not increase, stop turning the Level control to the right as the amplifier/speaker combo has reached its maxx

output in this application.

HERCULES / ATLAS / COLOSSUS

General:

At this point you are ready to get more specific on the settings for your amplifier.

Phase:

Time alignment, typically recommended at 0 degrees unless using multiple amps and subs in both the front and rear of the vehicle. The Phase can be adjusted to give the perception of bass reaching

the listener at the same time regardless of location.

Subsonic:

This setting acts as a low frequency cut off for your system bass reproduction. The point that you set it at cuts off any frequencies from reproduction below this point. EXAMPLE: If you adjust the

Subsonic to 25Hz, the amplifier will not play frequencies below 25Hz but will play frequencies from 25Hz to the chosen Low Pass frequency.

PARAMETRIC BASS EQ:

Frequency:

This setting is used for selecting the frequency you want to focus your enhancement on. Suggested enhancement is from 35-45Hz, but you should be careful not to set enhancement below the F3 or

-3dB point of your sub/enclosure combo.

Bandwidth:

This setting controls the amount of frequencies included in the Bass Boost. The bandwidth varies from narrow to wide in a pyramid style boost with the selected Bass Frequency value being the

center.

Boost:

This setting adjusts the amount of boost on the selected Bass Frequency and Bandwidth. This setting is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it

can be over used and cause damage to your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o'clock

position unless listening at a low volume or a low recording quality as this can result in high distortion and possibly clipping.

Low Pass:

The Low Pass control acts as a ceiling and doesn't allow frequencies above the desired setting to be reproduced. EXAMPLE: If you adjust the Low Pass to 80Hz, the amplifier will not play

frequencies above 80Hz but will play frequencies from 80Hz to the chosen Subsonic frequency.
