User manual DLS RA30

[. . . ] There is one such list of material on the following page. Disconnect Battery Before starting the installation, always disconnect the negative terminal of the battery. Amplifier location Important Allow air circulation around the amplifier. The DLS Reference series of amplifiers have a compact design that allows great flexibility in mounting. When you select a location, do remember that the amplifier generates a lot of heat. Choose a location where air can circulate freely around the amplifier. [. . . ] You can feed all four channels using high level input, or feed two channels from RCA and two channels using high level input from rear speaker cables. CH 3&4 high level inputs feeds the sub channel. CH4 CH3 Hi level input socket on amp. Green: Left + Black: Left Black: Right Grey: Right + Hi level input plug. High / Low level input switch To ensure best possible performance from the amplifiers a switch is installed to select between Hi and Low input. When using High Level input: Push in the button to position "High Level" When using Low level input: Push out the button to position "Low Level" High Level Input for ch 1 & 2 on RA25 and RA30 Connect left and right speaker wires coming from the car stereo to the high level input as shown. You must connect both plus and minus as the inputs are balanced, connecting plus only gives lower level and bad sound quality. High level input socket for CH 1 & 2 Green: Left + Black: Left Black: Right Grey: Right + Hi level input plug. Hi level auto start switch To ensure best possible performance from the amplifiers when used with high level input a switch is installed to select between Automatic amplifier start and remote wire start. When using High Level input with automatic start: Push the button to position IN When using High level input with remote wire start: Push out the button to position OUT NOTE!Some head units use BTL output IC:s that have a constant 12 Volt + on the speaker terminal, also when shut off (the Power LED indicator lights constantly even when the head unit is off). In this case you have to use a separate remote wire connected to the REMOTE-terminal instead. 5 CH2 CH1 Hi level input socket on amp. Automatic turn on when using high level input. With the "Input selector switch" set to High level and the "High level Auto Start" switch set to IN, the amplifier turns on automatically on high input. You don´t need to connect a separate remote wire from your head unit. If you want to use high level input but use a remote start wire, just set the "High level Auto Start" switch to OUT. RA25 & RA30 Input Level control The input level control, 7V ­ 0, 2 V, matches the output of your radio to the input of the amplifier. After installation is complete, make sure the input of the amplifier is turned down all the way ( counter-clockwise at 7V ). GAIN Crossovers The DLS Reference amplifiers include high pass filter (HP) and low pass filters (LP). The high pass filters can be switched off if you want to run the amplifier in full range mode. It can be connected either as a stereo amplifier for fullrange speakers, or as a mono amplifier for a single driver connected in bridge mode. Two fullrange speakers connected in stereo mode One speaker connected in mono bridge mode + - + + - Filter settings NOTE!You can also run a front system in bridge mode using two RA25 amplifiers, one for each channel. If you want to use the RA25 for bridge mode connection of a subwoofer, you must use an external passive lowpass crossover. With the HP-filter in OUT position the amplifier allows the speakers to play fullrange. If you for some reason want to limit the low bass reproduction switch IN the HP-filter. The typical setting is then around 60 ­ 80 Hz. 7 RA30 Speaker wiring RA30 RA30 is a 3-channel stereo amplifier. It is normally used to connect one pair of front/rear fullrange speakers, and one or more subwoofers connected to the mono sub channel. Two fullrange speakers and one subwoofer to RA30 Filter settings channel 3 & 4 + The LP-filter will allow low frequencies only and blocks higher frequencies. [. . . ] Crimp tightly 10 Professional Tip: Speaker and power wires Do not run speaker and power wires next to each other. Run speaker and power wires on opposite sides of the car.
