[. . . ] this product meets the current EU minimum warranty requirements , if purchased in countries of the EU. To ensure your warranty policy keep your original receipt proofing the date of purchase. All other part and accessories of the system are warrantied to be free from defects in material and workmanship for one (1) year from date of purchase. Maxxsonics will repair or replace at it's option and free of charge during the warranty period, any system component that proves defective in materials and workmanship under normal installation, use and service provided that the product is returned 2 to the authorised MB QUART dealer from where it was purchased. [. . . ] - BP: Selects the built in LOW PASS filter, variable from 30 Hz to 150 Hz. - Full range signal from channels 1/2 inputs are routed to the Line OUT RCA jacks, regardless of the setting of the X-OVER switches. These inputs can be used in various combinations, to suit the application, depending on the settings of the INPUT MODE switch, and the X-OVER switches for channels 1&2, and channels 3&4, respectively. INPUT MODE slide switch: - In the CH2 position, ALL five amplifier inputs are selected from the CH1/CH2 RCA jacks. - In the 4CH position, channel pair 1&2 receive input signal from RCA jacks CH1 and CH2, and channel pair 3&4 receive input signal from RCA jacks CH3 and CH4. A mono mixed signal from these four RCA jacks are also fed to channel 5. - When 5CH DISCRETE is selected, each channel receives an input signal from its respective input RCA jack. : In this mode, the HIGH PASS and a LOW PASS filter, both fully variable from 50 Hz to 4 KHz, are selected to form a BANDPASS crossover filter. CH 5: - The channel 5 functions were chosen to be very specific to mono bass operation, and not switchable: - The LOW PASS filter has a variable range from 30 Hz to 150 Hz. - The input sensitivities for rated output powers are variable from 0. The 1 channel mono amplifiers are capable of 4, 2 & 1 ohm loads and can be used in any of the "bi-amplifier" systems described in the 2 and 4 channel directions. Level control checklist: Refer to the section "Setting up systems after installation for best performance" Minimum final loudspeaker impedances: - 2 ohm per channel in stereo mode. 2 way active, or bi-amplified system with mono bass English 9 This application shows how easily a 2 way active system can be implemented using a Premium 4 channel amplifier. channels 1 and 2 will be used for highs , and channels 3 and 4 for mono bass. Interconnect cable checklist: We need to feed the same signal to both sets of channels, so must use 2 Y-adapters, one to feed the LEFT signal to channels 1 and 3, and the right signal to channels 2 and 4, as shown. mono bass woofer wiring: Connect the mono speaker positive terminal to the LEFT + , and its negative terminal to RIGHT -. Switch setting checklist: - 1/2CH X-OVER: HI - 3/4CH X-OVER: LP/BP Crossover frequency control checklist: Channels 1/2: Channels 3/4: - HI PASS: 100 Hz - HI PASS (subsonic): 20 Hz - LOW PASS: N/A - LOW PASS: 100 Hz Please note that these frequency points are suggestions only. the LOW PASS filter on channel 5 will be in tandem with that of the source. You can either set it to the same frequency for a steeper rolloff, or set it to a higher frequency to minimize it's effect. Switch setting checklist: - INPUT MODE: 5CH DISCRETE - CH 1/2 X-OVER: FULL - CH 3/4 X-OVER: FULL Crossover frequency control checklist: - CH 1/2 HIGH PASS: N/A - CH 3/4 HIGH PASS: N/A - CH 3/4 LOW PASS: N/A - CH 5 LOW PASS: 100 Hz Please note that these frequency points are suggestions only. Refer to the loudspeaker manufacturer specifications and the section "Setting up systems after installation for best performance" Level control checklist: Refer to the section "Setting up systems after installation for best performance" Minimum final loudspeaker impedances: 2 ohm per channel 3 or 4 channel discrete, one being mono low pass We will use the same basic setup as above to illustrate a 3 channel arrangement, by mono bridging the stereo channel pairs 1&2, 3&4. Interconnect cable checklist: - Use 2 Y-adapters RCA cables, one for channels 1&2, and the second for channels 3&4, to create 2 inputs for channels 1, 2, 3&4 only, as shown. [. . . ] Description of the Diagnostic system built into all MB QUART amplifiers: The diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front panel PROTECT LED lighting up under the following conditions: 1 - A short circuit on the loudspeaker leads. 2 - An internal amplifier fault that causes a DC offset on the loudspeaker output. Should the amplifier go into diagnostic mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected. [. . . ]
