Resumen del manual


2 - A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow. System does not turn on 1 - Check all fuses. 2 - Check all connections. 3 - Measure the +12 volt and remote turn on voltages at the amplifier terminals. If these are non existent or low, take voltage measurements at fuse holders, distribution blocks, the head unit’s +12 volt and remote leads to localize the problem. Noise problems System noise can be divided into two categories, hiss, and electrical interference. Hiss, or white noise 1 - High levels of white noise usually occurs when amplifier level controls are turned up too high - readjust according to the procedures in section ”Setting up systems after installation for best performance” 2 - Another major problem that can cause excessive hiss, is a noisy head unit - unplug the amplifier input RCA cables, and if the hiss level reduces, the source unit is at fault. Electrical interference The inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system, alternator, fuel pumps, air conditioners, to mention just a few, create radiated electrical fields, as well as noise on the +12 volt supply and ground. Remember to isolate the problem - first unplug amplifier input RCA cables, if the noise is still present, check the speaker leads, if not, plug the RCA’s back, and investigate the source driving the amplifier, one component at a time. A ticking or whine that changes with engine RPM: 1 - This problem could be caused by radiation pickup of RCA cables too near to a fuel pump or a distributor, for instance, - relocate cables. 2 - Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory wiring for ground. 3 - Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in dash wiring/fusebox. A constant whine: This type of noise can be more difficult to pinpoint, but is usually caused by some kind of instability, causing oscillations in the system. 1 - Check all connections, especially for good grounds. 2 - Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis. 3 -RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections. 4-Channel Amplifiers ONX4.60 / ONX4.80 / ONX4.125 5 CH3/4 CH1/2 LINE OUT R L R L LINE INPUT LEVEL 6V 0.2V 0dB 12dB FULL LPF HPF 60Hz 13KHz 30Hz 250Hz BASS EQ X-OVER HPF LPF 6V 0.2V 0dB 12dB FULL LPF HPF 60Hz 13KHz 30Hz 250Hz POWER PROTECTION MODE 2 3 4 FEATURES: - 2 Sets of RCA inputs - LEVEL: Variable sensitivity from 0.2V to 6V - BASS EQ: Adjustable 45Hz bass boost from 0dB to 12dB - X-OVER: Selects internal crossover functions - FULL: Bypasses all crossovers for full frequency operation - LPF: Selects the built in LOW PASS filter, variable from 30Hz to 250Hz - HPF: Selects the built in HIGH PASS filter, variable from 60Hz to 13KHz - POWER LED: Indicates the powered up and turned on condition - PROTECTION LED: Indicates a high voltage, low voltage, short circuit, hard clip, over heating or DC fault condition. - MODE: “2” indicates one set of RCA’s are being used. This will also pass signal to channels 3/4 through 1/2 inputs. “3” indicates bridging channels 3/4 while running 1/2 in stereo. “4” indicates connecting 2 sets of RCA’s to 1/2 and 3/4 inputs. - LINE OUTPUT: Full range RCA pass through. 4 Channel Full Range Stereo: Interconnect cable checklist: Control checklist: - Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables. - Refer to the section “Settings for Best Performance” Switch setting checklist: - 1/2CH X-OVER: FULL Minimum final loudspeaker impedances: - 3/4CH X-OVER: FULL - 2 ohm per channel. MODE: “4” since 2 sets of RCA’s are connected. 2 or 3 Channel System: Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the output stage of that source. Here we show how to use the 4 channel amplifiers as a 3 channel unit by taking - It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter RCA cable. advantage of the mono bridging capability of all MB Quart amplifiers. In order to create - Connect the mono speaker positive terminal to the RIGHT +, and its negative terminal to LEFT a 2 channel system, simply follow the example to also mono bridge channel pair 1/2. - as shown. Interconnect cable checklist: - Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit Switch setting checklist: with good quality RCA cables. - 1/2CH X-OVER: FULL - A MONO signal source is required t...
