    User Interface Input Gain Controls: Use these controls to match the pre-amp output level from your car audio source unit. DRIVE20 MAX Input level: 8 VRMS (18 dBV) Subwoofer Gain/Frequency: These two controls adjust the level of the signal sent to the separate SUBWOOFER OUTPUT terminal, and also adjust the Low-Pass filter point.
  • Page 8 User Interface Output Gain Controls: Each frequency band has a pair of Output Gain controls. Use these controls to match the optimum pre-amp input level of your amplifier. DRIVE20 MAX Output level (DSP@ 0 dB): 3 VRMS (9.6 dBV) Generally speaking you should set DRIVE20's output level controls at about 8/10 and your amplifier's gain control at its lowest possible sensitivity setting, taking care not to run the sound into distortion.
  • Page 9 This manual only covers setup and adjustment using the panel buttons. Setup Introduction Of all the ALTO Mobile sound processors, DRIVE20 (and sister model DRIVE30) is potentially the one most likely to cause damage to your speakers if it is not setup correctly. You must take great care when setting the crossover points for the mid and high bands.

  • Page 11 Parameter Menus & Setup Preset Load 65 presets are available, one factory preset and 64 user-definable presets. Preset 0 is the default factory preset used as a start point when configuring the system. Attempting to load an empty user preset will produce a warning message on the display.

For each of the 4 Output Channels you can choose to send just the Left Input signal, the Right Input signal, a combination of both Left and Right Input signals (usually for feeding subwoofers) or no input (OFF).
  • Page 15 Parameter Menus & Setup Gain (cut/boost), Frequency (the centre frequency of the filter), and Band Width (the extent to which frequencies around the centre frequency will also be adjusted). Delay: This allows a delay to be set on each channel. May be useful in certain circumstances. Also, setting a delay on one side while leaving the other with no delay can produce a very interesting effect of added width and spatial depth.

  • Page 21: Installation Instructions

    Installation Instructions Mounting the Unit DRIVE20 has two fixing 'ears' at each side, allowing it to be firmly screwed to a suitable surface. It may be mounted vertically or horizontally. Take care not to mount the unit where it may become wet or subject to damage from items placed in the trunk area.
  • Page 22 Installation Instructions At the far right of the side panel is a POWER INPUT terminal block with three screw terminals. The terminal marked 12V should be connected to a permanent 12 Volt supply from the vehicle battery. The terminal marked GND (Ground) should be connected to a cable which is terminated to the vehicle chassis.

  • Page 23: Rs232 Computer Interface

    RS232 Computer Interface A standard RS232 computer serial interface socket allows connection of DRIVE20 to a computer capable of running Windows compatible software. A dedicated software package is available to setup DRIVE20 more easily using a computer. DRIVE20 should be connected to a suitable computer using a ' null modem ' type serial interface cable (not supplied).
