1. 6 Essentially this is your master volume control Monitor the Stereo Signal Level Meter 21 to ensure your level does not exceed the 3 dB mark and begin clipping The optimum position for this control will produce a signal in the 0 dB range just slightly lighting the red LEDs at the highest peaks 17 X FADER This stereo slider delivers crossfade capability between any two input channels 1 4 You will find an X Fader Assign selector on each side of the X Fader These are used to select the two input channels that the X Fader will crossfade between Adjusting this slider from its maximum left position to its maximum right position will pan the main output from being completely one channel the channel selected on the left X Fader Assign to completely another channel the channel selected on the right X Fader Assign The interim from left to right would produce a combination of both allowing a smooth transition from one channel to the other Note The X Fader is replaceable by removing the two outside mounting screws on the top of the unit Once the screws have been removed the slider can be pulled out and replaced with ease 18 X FADER ASSIGN The two X Fader Assign selectors determine which two channels the X Fader 17 controls These two selectors are located on each side of the X Fader If Channel 1 is chosen on the left selector and Channel 4 on the right moving the X Fader from far left to far right will change the output mix from C2. Channels 1 and 2 feature identical input options PHONO and LINE On these two channels you may select using the Input Select Switch 14 either PHONO for phono players or LINE for line level products such as CD Minidisc drum machine or DAT This type of configuration allows you to connect both types of products to the same channel and conveniently select between them during a performance Remember that this combination of inputs PHONO and LINE is only available on Channels 1 and 2 CAUTION DO NOT CHANGE THE CHANNEL INPUT SELECT SWITCH FROM THE LINE POSITION TO THE PHONO POSITION WHILE THE CHANNEL FADER IS TURNED UP ABOVE 3 AND MATERIAL IS BEING PLAYED THESE TWO TYPES OF SIGNALS DIFFER IN LEVEL SWAPPING BETWEEN THEM WILL NOT ALWAYS PRODUCE EQUAL OUTPUTS FROM THE PM ONE DOING SO COULD RESULT IN DAMAGE TO BOTH HEARING AND OR EQUIPMENT Channels 3 and 4 are different however Channel 3 offers two stereo LINE inputs No PHONO inputs are available for Channel 3 You may select between the two LINE inputs using the Input Selector Switch for Channel 3 Channel 4 has only one stereo input since its Input Selector Switch is used to select the Mic 2 Input 10 All output levels from your external equipment should be set to maximum levels without causing distortion This can sometimes be more evident by listening to the specific channel in the Cue through headphones One important thing to remember is that your objective is to place all ch
