[FLAT]: for a longer smooth fading curve
[STP]: for a fast steep fading curve (mostly used for scratching)
7. [X-MASETER-Y] routing selector: use this switch on each chanel to send your signal :
[X] = to the X channel of your crossfader,
[Y] = to the Y channel of your crossfader
[MASTER] = directly to the MASTER output without passing through the crossfader
8. CHANNEL VU meters: to monitor the input level of each channel. The RED Leds should never be
continuously on. This means your signal will be distorted, what can damage your sound system !
9. INPUT SOURCE SELECTOR: Used to select the desired source input on each channel: Mic, Phono,
line or USB.
