User manual AUDISON VR 404 XR

[. . . ] this device has four 50 W RMS on 4 Ohms channels and a 200 W RMS on 4 Ohms and 290 W RMS on 2 Ohms channel , specific for SUBWOOFER. Channels are driven by a sophisticated crossover which can be configurated at two or three ways through Mode switch; in both configurations, one way, which has a 24dB slope, is dedicated to the SUBWOOFER, which is also supplied with FADER CONSTANT BASS function (Subwoofer constant level when Front/Rear level is varied through Fader control). [. . . ] The crossover has four independent adjustments for cut-off frequencies, three adjustments for output levels, two preamplified output/input connectors. The FRONT section is driven by the IN FRONT input, which handles a Lo Pass filter (50 Hz - 150 Hz) for SUBWOOFER, and a Hi Pass filter (50 Hz - 150 Hz); each filter is supplied with a frequency and level control. The REAR section is driven by IN REAR input, which handles a Hi Pass filter (50 Hz - 150 Hz), equal to the one of the FRONT section, with its own frequency and level control. it handles a Lo Pass filter (50 Hz - 150 Hz) for SUBWOOFER , a Band Pass filter for WOOFERS (50 Hz - 150 Hz / 150 Hz - 850 Hz) and a Hi Pass filter for MID-TW (150 Hz - 850 Hz). The crossover frequencies between SUBWOOFER and WOOFER are handled by two independent frequency adjusters. Cut-off frequency between WOOFER and MID-TW is controlled by a single adjuster. Each of the three power outputs is adjusted through its own level control. Turn radio-cassette player volume down until there's no longer any distortion. Then adjust the amplifier calibration levels until you hear slight saturation phenomena. SAFE When lit, it indicates the intervention of protection circuits: in case of overheating (temperature exceeding 80°C/176°F) or output anomalies (preence of continuous current, short circuit or dangerously low load impedance). They are Hi Pass filtered, in a range of frequencies between 50Hz and 150Hz (12dB/Oct. They are Hi Pass filtered, in a range of frequencies between 50Hz and 150Hz (12dB/Oct. ), adjustable through F2, and Lo Pass filtered, in a range of frequencies between 150Hz and 850Hz (12dB/Oct. They are Hi Pass filtered, in a range of frequencies between 50Hz and 150Hz (12dB/Oct. [. . . ] They are Hi Pass filtered, in a range of frequencies between 50Hz and 150Hz (12dB/Oct. They are Hi Pass filtered, in a range of frequencies between 150Hz and 850Hz (12dB/Oct. [. . . ]
