User manual JBSYSTEMS ENH2.3

[. . . ] It must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. When the power switch is in OFF position, this unit is not completely disconnected from the mains!This appliance must be earthed to in order comply with safety regulations. Always replace a damaged fuse with a fuse of the same type and electrical specifications! [. . . ] Condense sometimes prevents the unit from working at full performance. Basically the unit is connected between the music source (any line output is possible) and the unit that will be used to record or amplify the music: In most cases SE100 will be used to enhance the sound quality and bass punch in PA systems and discotheque sound systems. The SE100 will be connected behind the master output of the audio mixer. You can also use the subwoofer output to drive an extra subwoofer amplifier which results in an additional power punch!SE100 can be inserted in the monitor send of a PA mixer to enhance the sound quality of monitor speakers. SE100 can also be used between a tape deck and mixing console to enhance the sound of the tape deck. SE100 can be connected between the record output of a mixing console and a tape deck to enhance the sound that will be recorded. SE100 can be used to correct the loss of sound quality, caused by all kinds of effect equipment. In this case put the SE100 as last unit in the chain of effect equipment. SE100 can be used to compensate the loss of sound definition during tape duplication: the copy can be even better than the original!Put the SE100 between the output of the playback deck and the input of the recording deck. When the button is pressed the blue led turns on to indicate that the processor works. You can use this switch to compare the sound with and without processing. LOW MIX control: Controls the amount of low band signal, produced by the bass processor, used for sound enhancement (from zero to maximum). The setting depends on the application and can be adapted to your own taste. When adjusting, use the ACTIV switch to compare between original and processed sound. Important: Note that the bass processor should be used with care to avoid possible speaker damage. Most smaller and economical speakers are not capable of handling the low frequencies produced by this unit. In a range from 1kHz to 8kHz you can select the frequencies that are routed to the high band processor. When adjusting, use the ACTIV switch to compare between original and processed sound. HIGH MIX control: Controls the amount of signal, produced by the high band processor, used for sound enhancement (from zero to maximum). It can be used to give a high-quality system the little "finishing touch" it needs or you can add some extra clarity to a relatively poor sound system. [. . . ] Mains input: connect the sound enhancer to the 220V AC mains, using the supplied power-cord. OUTPUT control: Controls the level of the subwoofer output from zero to +12dB. Start from zero and slowly turn in clockwise direction until the amount of low frequencies seems to be OK for you. CLIP LED: When the subwoofer output level is too big, clipping may occur. [. . . ]
