[. . . ] The product should be positioned so that proper ventilation is maintained. Please make sure that the power unit supplied is marked for the correct voltage in your area (120VAC/60 Hz or 230VAC/50 Hz). Power requirements for electrical equipment differ from area to area. In new installations and portable sound systems, or any situation in which the AC power is in question, it is wise to confirm the voltage and use the appropriate power supply unit before connecting it to power sources. Europe (except UK): 230V, 50Hz UK and Australia: 240V, 50Hz USA and Canada: 120V, 60 Hz For other areas, please check with local authorities. When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC power source to avoid possible loud transients which can damage your speakers or your ears. 4 FRONT CONTROLS AND CONNECTIONS CHANNEL SECTION (1) MIC INPUT This electronically balanced XLR input is designed to accept signals from any balanced or unbalanced low impedance (Low Z) microphone. The XLR jack is configured for: Pin1 = ground, Pin2 = positive (+), Pin3 = negative (-). (2) LINE INPUT This 1/4" input is designed to accept balanced or unbalanced linelevel signals such as those from keyboards, drum machines, or samplers. If a balanced signal is to be connected to the line input, then a 1/4" TRS (stereo) phone plug should be wired for: Tip = positive (+), Ring = negative (-), Sleeve = ground. (3) (4) (Note: Only the Mic or the Line input of a given channel should be connected at one time. Do not connect both at the same time. ) (3) TREBLE EQ Turn to the right to boost high frequencies, adding crispness too percussion from drum machines, cymbals, and synths. Turn to the left to cut these frequencies, reducing sibilance or hiss. The audio mix is adjusted by the EFF control of each channel. The signal output is not effected by the internal reverb. The Effects Return input jack can be used to return the signal into the SPM-9700 or it can be used as another auxiliary input for line level devices. The input signal can be adjusted using the Effects Return Volume (14) and also the output volume of the external device. (14) EFFECTS RETURN VOLUME The Effects Return input signal can be adjusted using this control. (15) LEFT-RIGHT / MAIN MASTER VOLUME This control sets the level of the stereo left and right signal sent to the left and right Speaker Outputs (19) when the Power Amp Selector Switch (18) is set to Left-Right. When the selector switch is set to Monitor-Main, this control adjusts the level of the Main Speaker Output (19). (16) MONITOR MASTER VOLUME This control sets the level of the Monitor mix sent to the Monitor Speaker Output (19) when the Power Amp Selector Switch (18) is set to Monitor-Main. This control is not active when the selector switch is set to Left-Right. (17) STEREO 5-BAND GRAPHIC EQ The dual 5-band graphic equalizers allow you to adjust the frequency response of the Left-Right outputs, or the Monitor-Main outputs, allowing final tonal adjustments. These provide a maximum of 12dB cut or boost from the flat position for each frequency band; 60Hz/ 250Hz/800Hz/2KHz/8KHz. [. . . ] For maximum cooling, ventilation, and efficiency, keep mixer away from walls or other objects. (20) POWER CONNECTOR & FUSE COMPARTMENT The IEC socket is used to connect the power cord to an AC power source. Replace with only the same type fuse as listed in the SPECIFICATIONS. If it blows continuously, do not use the unit and have it serviced by qualified personnel. [. . . ]
