TM Safety Instructions LT LTO O All safety and operating instructions - including those supplied with the UCS PRO - should be read before the UCSPRO-RM2 is installed and operated. We recommend that installation be carried out by an authorized TM mobile electronics installation company. Please contact your local ALTO Mobile distributor for a list of authorized installers in your country. To reduce the risk of electric shock and potentially damaging the equipment, do not disassemble the product. N

TM LT LTO O Introduction TM Thank you for choosing the ALTO Mobile UCSPRO-RM2 Programmer for the Alto Mobile UCS PRO digital signal processor. The UCSPRO-RM2 provides an alternative to using a Personal Computer (PC) for setting the various functions of the UCS PRO. It is primarily designed to be bolted to the UCS PRO but can be detached and, using an optional extension data cable, used remote from the main unit (such as handheld at the driver's seat) during system set-up. While unable to offer t

TM Introduction LT LTO O Block Diagram: UCS PRO There are no controls on the UCS PRO itself. Setting the parameters of the UCS PRO is achieved in one of two ways - either by using the UCSPRO-RM2 Programmer, or by connecting a suitable computer to the 9-pin RS232 serial interface and running Alto's dedicated PC Editor software. Set-up using a PC is covered in the UCS PRO user manual and the program's Help file 3

TM LT LTO O CONNECTING THE RM2 TO THE UCS PRO Ensure power to the UCS PRO and the rest of the audio system is switched OFF. At each side of the panel of the UCS PRO that carries the 25-pin connector, remove the bolts securing the cover of the UCS PRO*. You will need a suitable Allen key to remove these bolts. (*The top cover of the UCS PRO may also be completely removed, rotated 180 degrees and refitted so that the inscription faces forward. We recommend your dealer does this for you). A D-SUB 2

TM Using the RM2 remotely from the UCS PRO LT LTO O If you wish to use the UCSPRO-RM2 remotely from the main UCS PRO, you will need to obtain a Serial DB25 (25-pin) male-female Extension cable (not supplied). For example, Belkin 3m extension cable, code F3D112b10, or other computer grade extension data cable. Ask your Alto dealer or local computer retailer. Avoid using a cable length of more than 5 meters - with long cables, inferior types of cable, and in areas of high emitted interference, rel

TM LT LTO O EDITING PARAMETERS USING THE RM2 The UCSPRO-RM2 uses a backlit LCD display, a set of buttons and a very user-friendly, continuously adjustable rotary control to allow full editing control of the UCS PRO. When you switch on power to the UCS PRO, the RM2 will show an initial welcome screen (showing the internal software version number). This will last for about 5 seconds while the UCS PRO initialises. During this period it restores the set-up that was active when it was last switched o

TM Parameter & Functions Set-up Guide LT LTO O Press ESC to quit the Input Gain Setting mode. It is important to optimize the Input and Output Gain settings of the UCS PRO to ideally match the output from your car audio head unit and the input stage of your power amplifier(s). The optimum settings will ensure the lowest possible noise and no distortion. While set-up by ear is possible, the best results will require use of a voltmeter and oscilloscope, and this is therefore generally best left to

Bandwidth: This dictates how the frequencies next to the center frequency will be affected during gain boost or cut (Peaking & Notch modes). With a narrow bandwidth (minimum 0.05 octave), frequencies other than the center frequency and its immediate neighbours will be largely unaltered. With a broad bandwidth (maximum 3 octaves), gain changes will be s

The effect of this control is summed with that of the 0/180 degrees Output Polarity (Output Pol.) function described a little further on. In this way it is possible to adjust the phase of each individual output through a full 360 degrees. When you have completed adjustments for Output 1, press NEXT.

TM Parameter & Functions Set-up Guide LT LTO O Compressor/Limiter (Edit Menu): The Compressor/Limiter (Output CompLim) function allows the signal of each individual output to be kept within a set level range. This gives several benefits. By limiting peak output levels it helps protect the components of a sound system and at the same time provides a more consistent listening level. It also allows a higher average listening level, so that softer parts of the music can be more clearly heard without

Turning the rotary control counter-clockwise selects various compression ratios, from 20.0 to 1.1. A compression ratio of 20.0 (also written as 20:1) means that for every 20dB increase (above the set Level Threshold) at the input of that channel, the output from that channel will increase by just 1dB. This is very heavy compression - almost Limitin
