[. . . ] Do not operate for a long period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an audiologist. The product should be positioned so that proper ventilation is maintained. The product should be located away from heat sources such as radiators, heat vents, or other devices (including amplifiers) that produce heat. [. . . ] Turn to the left to cut these frequencies, reducing sibilance or hiss. The control has a shelving response giving 15dB of boost or cut at 12kHz. (3) LEVEL CONTROL The Level Control determines the proportion of the channel signal in the mix, and provides a clear visual indication of channel level. (4) MIC/LINE INPUT The MIC/LINE is via a combo connector, which allows the connections of XLR or 1/4" type phone jack. Please use a low impedance microphone and a properly wired cable for best results, When the 1/4" phone jack is plugged into the combo connector, the connection can be either a microphone or line level signal. (5) DIGITAL DELAY (DD) This knob determines the signal level which will be sent to the built-in DIGITAL DELAY Effect (6) control (6) DIGITAL DELAY The signal from the input channels, processed by the built-in digital delay will feed to the master output. There are three knobs here to control the effect of the delay. (6a) SWITCH This push button switches the delay effect ON/OFF. (6b) LEVEL This knob adjusts the mix level of the effect sound. (6c) TIME (ms) This knob selects 80ms, 120ms, 160ms, or 200ms of delay as desired for your intended effect. (7) POWER ON LED INDICATOR Indicates when the unit is ON. (8) TAPE LEVEL CONTROL This knob adjusts the level of signal from the TAPE IN (10) to the Main bus. (9) MASTER CONTROL This adjusts the final level of the Main bus. It controls the Main bus signal which is output to the speakers. 6 REAR CONNECTIONS (11) (12) (14) (15) (10) (13) REAR PANEL (10) TAPE IN AND TAPE OUT The TAPE IN allows cassette recorders or CD players to be added to the Main output. The RECORD OUTPUT, with TAPE RCA jacks, provides signal output to a cassette deck or Home audio equipment. The nominal output level and impedance are 10dBV/600 ohms. (11) POWER SWITCH Turns the unit ON or OFF. Always turn level controls down before turning on the unit. (12) VOLTAGE SELECTOR SWITCH For selecting the proper voltage (115/230VAC) to match the power supply in your area. Note: To avoid damage to your unit, always make sure this switch is set to the correct supply voltage. Damage caused by improper use is not covered by the warranty. (13) POWER CONNECTOR WITH FUSE HOLDER This standard IEC power cord receptacle is used to connect the AC power to your unit.
