CONTROLS AND FUNCTIONS

TUNING BASSLINK T

BassLink T provides several controls and indica- tors that simplify sonic integration with virtually any vehicle’s unique acoustic properties.They are located on the top control panel, as shown in Figure 13.

GAIN Control: Use this control to adjust the relative volume (loudness) of BassLink T with respect to the other speakers in the vehicle.

CROSSOVER: Use this control to adjust the amount of high-frequency information present in BassLink T’s output. A lower value means more of the high frequencies are filtered out.

BASS BOOST: Use this control to correct any perceived peak or dip in the bass response (typically around 40Hz in most vehicles). Set the control to any value between –6dB and +3dB, according to your preference.

PHASE Control: Use this switch to reverse the phase of BassLink T’s output with respect to its input. Choose the position (0° or 180°) that sounds the best.

Figure 13. BassLink T control panel.

NOTE: Depending on BassLink T’s orientation and location in a vehicle, reversing the phase may (or may not) increase or decrease the amount

of perceived upper bass being reproduced.

AUTO TURN-ON:For speaker-level connections, use this switch to activate (or deactivate) BassLink T’s automatic turn-on circuit.

REMOTE LEVEL CONTROL: Use this RJ11 jack

to connect the Remote Level Control (see page 6).

PEAK LED: This indicator glows red when the subwoofer is at maximum output. Be sure to monitor this indicator during BassLink T setup (see Tuning BassLink T). When properly tuned, the PEAK LED should light momentarily during high-level bass transients. Avoid adjustments that cause the PEAK LED to remain lit for extended periods.

POWER LED:This indicator will glow blue when BassLink T is operational.

1.

Unplug the RJ11 cable that connects the

 

Remote Level Control to BassLink T.

2.

Make sure the head unit is off and its volume

 

control is set to minimum.

3.

On BassLink T’s top panel, initially set all

 

controls to their midpoint positions, as shown

 

in Figure 13. On BassLink T’s top panel,

 

initially set PHASE to 0°.

4.

Turn on the head unit and play a favorite

 

music track that has substantial bass. Set the

 

head unit’s volume control to 75 percent of

 

the total output (approximately 3 o’clock on

 

rotary controls).

5.

Adjust the GAIN control clockwise until the

 

PEAK LED (on BassLink T’s top panel) begins

 

to flash with each bass note but doesn’t stay

 

lit continuously.

6.

Listen to your system, making a mental

 

note of the amount of upper bass being

 

reproduced.

7.

Switch the PHASE control to 180° and listen

 

again for upper bass content.There may be

 

more upper bass, less upper bass, or no

8.Adjust the CROSSOVER control clockwise or counterclockwise until you hear only low- frequency information. For example, you should NOT hear any vocals coming from BassLinkT when seated in the normal listening position.

9.Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste.

10.Recheck the PEAK LED to make sure it’s flashing in time with the bass but is not lit continuously. If it is lit continuously, adjust the GAIN control counterclockwise until the PEAK LED only flashes.

11.Reconnect the RJ11 cable between the Remote Level Control and BassLink T. You may then use the Remote Level Control to adjust the level of the bass to suit your taste and/or different program material.

NOTE: In most cases, the above steps will provide satisfactory tuning. However, the actual process may require several readjustments of each control, since the settings will interact with each other.

If necessary, consult your authorized Infinity car audio dealer for help in tuning your system.
