Line Driver (included) for professional quality performance and noise cancellation. The 6-pin DIN plug carries (+) and (-) signal information for left and right channels, audio ground, and *I5 Vdc to operate the Soundstream BLT4TM Balanced Line Transmitter. Flexible Input Sensitivity - Variable input sensitivity controls for use with a balanced line transmitter, such as the Soundstream BLT4.

3-way for midbass / satellite operation on the front channels. Select 4-way operation for midbass / midrange / tweeter operation on the front channels. 31. A/RBASSTM Connector and Switch - Optional AIRBASS subwoofer level control connector and input switch. 32. GND - Main ground connection. Bolt to a clean chassis ground in the vehicle.
Mini-DIN Cable - The balanced line audio cable features a small convenient 6-pin mini-D I This cable carries (+) and (-) signal information for Left and Right channels, audio ground Vdc to operate the Soundstream BLT4. Flexible Input Sensitivity - The BLT4 is designed for optimum performance with a 5 volt balanced signal level.
INSTALLATION STEP 1 SELECTING THE CROSSOVER MODES The DaVinci amplifier incorporates a sophisticated, fully adjustable electronic crossover for each of its three pairs of channels and subwoofer channel. The DaVinci amplifier can drive a complete system without need of an outboard electronic crossover. INPUT OVERLOAD- LOW PASS The subwoofer channel is designed to operate in low pass or full range.
When operated this way, the low pass subwoofer channel will operate in a non-fading mode-it derives its signal from the Channel 1,2,3&4 inputs. included with the DaVinci amplifier is the Soundstream Limited Edition BLT4, which drives two pairs of balanced audio lines. This is perfect for front / rear fading capabilities, or as a subwoofer level controller.
Depending on your application, you may use one to four DIN audio balanced signal cables to drive DaVinci amplifier. Use the cables supplied with the BLT4 Balanced Line Transmitter, or see your local Soundstream dealer. SPEAKER CABLE The DaVinci will accept up to 8 gauge (4 gauge on sub channel) speaker cable. Use a high quality, flexible, multi-strand cable for best performance and longevity.
INSTALLATION STEP 4 INSTALLATION AND MOUNTING AMPLIFIER LOCATION The DaVinci amplifier employs highly efficient circuitry, an internal heat sink and fan cooling system to maintain lower operating temperatures. Make sure that no debris will be able to fall through the top plate of the DaVinci.
INSTALLATION STEP 5 CROSSOVER ADJUSTMENTS The crossover in the DaVinci is very flexible, allowing for high pass, bandpass and low pass filters to be set independently of each other. In most car audio installations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass frequencies.
BLT4 to the level of your head unit. (NOTE: To set the BLT4 level, Soundstream recommends using the Autosound 2000 Compact Disc #IO2 Track 27,l kHz 0 dB “all bits high” tone. If this CD is not available, a similar tone from a test CD can be used, or an extremely dynamic CD with a high crest factor.
“subsonic” bass energy. Soundstream’s LSE.Q contains the same type of circuit with the added benefit of infinite adjustability. Our “Q” and “Hz” control can provide virtually any combination of boost and cut to suit your designs.
AIRBASS (optional) Soundstream AlRBASS feature can be added to the DaVinci amplifier. This feature allows wireless RF remote control level adjustment of the DaVinci’s subwoofer channel. I - @ NOTE; The AlRBASS accessory option operates fhe subwoofer channel only. AIRBASS does not control the /eve/ of channels 7 - 6.
