TM LTO UCS PRO User's Manual Version 1.
TM Introduction LTO Dear Customer, Thank you for choosing the ALTO Mobile UCS PRO digital sound processor and speaker management system. We hope you will enjoy using this product as much as we enjoy ed developing it. The ALTO Mobile range is the result of considerable research and development in our R&D centers in Europe and the Far East. It is a very close cousin of ALTO's professional digital signal processors.
TM Care & Safety Instructions LTO All the safety and operating instructions should be read before this product is installed and operated. We IMPORTANT recommend that installation be carried out by an authorized mobile electronics installation company. Please TM contact your local ALTO Mobile distributor for a list of authorized installers in your area. DO NOT DISASSEMBLE: No user serviceable parts inside; refer servicing to qualified personnel only.

TM Opening Screen (PC Editor) LTO 1 2 3 4 5 6 7 1 8 A Windows compatible PC Editor is available for free download from our web site. To get a copy, go to http://www.altomobile.com/html/support_forum.html and click on the link "Data Resources / Downloads" and then "Software Downloads". R USEFUL TIP When you launch the editor on your PC, you will see the opening screen above (later software versions may differ).
TM Parameter Menus & System Set-up LTO There are no controls on the UCS PRO itself. The various parameters are adjusted by attaching the unit to a suitable Personal Computer (PC) running our dedicated Windows compatible PC Editor software (available as a free download from our website at www.altomobile.com). R Hook-up to the computer is achieved with the UCS PRO's 9-pin RS232 serial interface port, which is located on the same side as the audio input/output terminals.
TM Parameter Menus & System Set-up LTO RS232 > Port: Shows the current RS232 port (COM) used by the PC Editor and allows other choices to be selected, if available on your computer. RS232 > BAUD RATE: Provides options to select the communication speed. IMPORTANT Reliable data transmission can usually be expected as long as the cable length is not more than 5 meters. ADVANCED TIP The RS232 serial port default speed is 9600 bits per second.
Parameter Menus & System Set-up TM LTO If your UCS PRO has not been set-up yet, or if you want to replace the existing set-up, you can create a new named profile (NEW UNIT) within the PC Editor. Here's how: Select NEW from the FILE menu, then UCS PRO and click OK. Select NEW UNIT. In the window that appears, type a new name for the unit you are creating (this is optional). The Input/Output GANGING (* more information follows) options should generally be left at their default settings (unchecked).
TM LTO Parameter Menus & System Set-up Edit Mode (Password Protection) UCS PRO incorporates a password system and your installer may have set a password to ensure that vital settings are not altered. In this case you will NOT be able to alter all of the parameters via the PC Editor. In the PC Editor, select FILE > OPTIONS and then the LOCK tab. This will present you with a menu: Full Edit: This is the DEFAULT mode. No password is set at the factory.
Parameter Menus & System Set-up TM LTO 2 NOISE GATE: You can set the UCS PRO to cut the signal if it falls below a certain level. Most often used to cut the background noise between music tracks. 3 PARAMETRIC EQUALIZATION (EQ): Each of the channels (both inputs and outputs) has a fully variable 5-band parametric equalizer. 4 MASTER DELAY: Allows a delay to be applied to the signal fed from one or both of the Input Channels.
TM LTO Parameter Menus & System Set-up PRINT: Not a tabbed 'page' like those above, but an important function worth highlighting here. From the FILE menu, selecting PRINT provides a print-out of all the parameters of the UCS PRO, together with the GLOBAL graph. View it before printing by selecting PRINT PREVIEW. The UCS PRO Features Explained 1 GAIN CONTROL SECTION: The UCS PRO has no analog input or output gain controls - level adjustment is handled entirely in the digital domain.
Parameter Menus & System Set-up TM LTO relate to the speed with which the Gate closes and opens. The default settings will usually be fine and provide gating that works transparently, but you can use these settings to optimize the results if you hear any side-effects. Each gate can be switched in or out of the audio circuit by clicking on the OFF/ON button. The button will turn red when the Noise Gate is selected.
TM LTO Parameter Menus & System Set-up Notch - The Notch filter effectively removes a slice of the signal and is useful for targeting very localised problems. It can, for example, be used as an aid to tracing spurious noises caused by vibrating panels being excited at a certain frequency. Gain adjustment is disabled in this mode. 4 5 MASTER & CHANNEL DELAY: A wide ranging amount of delay, from as little as 21 microseconds (that's 0.
Parameter Menus & System Set-up TM LTO ADVANCED Temperature Compensation: This allows the current in-car temperature to be keyed in. The system uses this value to compensate for any variation in the speed of sound when calculating time delay. TIP This is a feature carried over from the pro audio version of the software and is more applicable to PA applications, in which it allows the delays to be set during the sound-check and quickly adjusted at the time of the concert if necessary.
TM LTO Parameter Menus & System Set-up Which filter type, slope and crossover frequency you should choose will depend on the speakers you are IMPORTANT using. Since it is important to set-up filter points carefully to maximise speaker power handling and avoid damage, this is usually best left to a professional car audio installer. Phase Adjustment: When using the Low-Pass filter, it is possible to adjust the phase of the signal in the low band in 5 degree steps.
Parameter Menus & System Set-up TM LTO The numerical values are dB values representing the amount of level increase at the input that will result in a 1dB increase at the output of that channel. So for example, selecting a value of 6.0 will mean that for every 6dB increase at the input, the output will rise by approximately 1dB. LIMITER is a very hard compression setting. It prevents the channel output from increasing by more than 1dB no matter how much the level rises at its input.
TM LTO Parameter Menus & System Set-up Working with Presets At the lower edge of the PC Editor window is a series of commands for recalling and storing PRESETS. To load a PRESET: Click on RECALL and then on one of the numbered red (FACTORY) or green (USER) PRESET buttons. The selected PRESET will be loaded and its name displayed in the text box. To save a PRESET: Click on STORE and then on one of the grey or green buttons (USER PRESETS). The grey color means it is an empty PRESET.
Installation Instructions TM LTO Mounting the UCS PRO The UCS PRO has two fixing 'ears' at each side, allowing it to be firmly screwed to a suitable surface. Take care not to mount the unit where it may become wet or subject to damage from items placed in the trunk area. The unit may be mounted vertically or horizontally, but avoid mounting it upside-down (i.e. suspended under a shelf) as this may affect heat dissipation.
TM LTO Installation Instructions from all electrical items in the vehicle, including: a). The CD player or other audio source unit, which may require a code number to reactivate it. Do you know the code? b). The security system, which may trigger an alarm from its back-up battery. Do you know how to override the alarm system? c). Memory modules, which may suffer memory loss if disconnected for too long. If you have any doubts, you should seek professional assistance.
Installation Instructions TM LTO REM The terminal marked REM (remote) accepts a +12V switched input from the source unit (CD player). When the source unit is switched on, a pulse is sent down this line. The UCS PRO senses this pulse and switches itself on. Your source unit should be equipped with a suitable Remote Switch cable - check the instruction book supplied with your Tape or CD player. Before reconnecting power to the circuit, double check all connections are correct and secure.
TM LTO Further Information Due to the nature of our digital sound processors, there are operational tips too numerous to include in an instruction manual such as this. For additional information, please visit our website at www.altomobile.com, which includes technical support and customer discussion forums, together with a downloads section for software updates, technical papers etc.
