Adjust the level lower than that by using the Gain Control. •Gain Controls This knob is to set the Gain level depending on the connected unit. Rotating this clockwise increases the level. •Treble Controls This knob adjust the treble. That is, rotating it clockwise boosts the high frequency range, and rotating it counterclockwise cuts it. •Bass Controls This adjusts bass sound. Rotating this clockwise boosts low frequency range, and rotating it counterclockwise cuts it. * When these knobs are set to zero, there is no boost or cutoff of harmonic contents, therefore fiat characteristics are obtained. • Effect Level Controls This sets the level of the output signal sent to each effect unit (=Effect send level!. *The pickup point of the Effect Send signal is post channel volume. •Panpot Controls The Panpot Control routes the input signal from an Input Channel to the left and/or right mixing busses. By means of the Panpot Controls, input signals can be sent exclusively to one mixing bus, or the other, to both mixing busses equally, or since the Panpot Control is continuously variable to both mixing busses in any relative proportion desired. •Channel Volumes This knob controls the volume of each channel independently. The "10" position gives the highest and ”0" lowest level. •Level Indicators This detects the level of the output signal. When "OdB” lights, the signal of -t-4dBm is being sent through the Output Jack. •Power Indicator This lights when the BX-800 is turned on. •Effect Return Level Control This knob controls the volume of eftggr sound. As you rotate it clockwise, volume increases. • Headphone Level Control As you rotate this knob clockwise, the headphones volume increases. This knob allows separate level setting free from the Master Volume. • Headphone Jack This can be connected to headphones. •Master Volume These are two independent controls which control the volume of the left and right channels, thus acting as an overall volume controls for the BX-800. At the “10” position, the volume is highest, and at '0' lowest. important Notes •The BX-800 may become warm during operation, but this is quite a normal situation caused by AC powered operation, so there is nothing to worry about it. • If the BX-800 is not in use, turn it off. • Please avoid using the BX-800 in extreme heat or humidity or where it may be affected by dust. ■CONNECTIONS Microphone III 1ГШ El III It — ; 1 ■ Keyboard Tape Recorder г Effect Unit Delay (Echo) Machine Delay 8 oool—II Digital Delay ®|№ЮИ Tape Echo ? v I 1111 Graphic Equalizer Power Amplifier Tape Recorder L-l* *- ». fllHlllll!
