MONITOR 1 AND 2 CONTROL These control determines the level of the post-EQ/pre-fader signal that is sent from the channel to the monitor mixing buses. All signal sent to the Monitor bus are mixed, then fed to the Monitor 1 and 2 Jacks on the top panel after their final output levels have been set by the Monitor 1 and 2 controls in the Master control section. 5.

OUTPUT LEVEL METER A vertical row of ten LED show the continuous output level of main Output L/R or monitor 1/2 by signal select switch. This type of display is free from over shoot problem of mechanical meters and is highly visible under poor lighting conditions. The 0 LED means an output level of +4dB for +4dB output (that’s the rated level). 2.

MONITOR 1, 2 OUTPUT CONTROL These controls adjust the overall output levels of the monitor mix that are setup using the monitor control of each channel. The Monitor 1 or Monitor 2 mix signal are sent to the monitor output 1 and monitor out 2 jacks on the top panel. These controls should be used to optimally match the monitor mix output levels to the input sensitivities of the power amplifiers used. 7.

PX-1650_E 2003.9.8 10:42 AM 페이지14 STEREO BUILT IN X-OVER 9. PHANTOM POWER ON/OFF SWITCH The PHANTOM ON/OFF switch turns the phantom power feature on and off. When turned on, this function supplies +48V power to the positive and negative terminals of the balanced XLR connectors via 6.8kΩ current-limiting/isolation resistors for use by phantom-powered condenser microphones. Signal sources that don’t require phantom power should be connected to the phone jack when phantom power is used.

PX-1650_E 2003.9.8 10:42 AM 페이지20 STEREO BUILT IN X-OVER Operating Tips ※ CAUTIONS FOR CONNECTED SOURCES Please observe the following cautions when connecting sound sources to the PX-1650. - TURN THE POWER OFF FIRST Always make sure that the mixer’s POWER switch is turned off before connecting or disconnecting any cables. Failure to do so can damage the PX-1650 or connected equipment.
PX-1650_E 2003.9.8 10:42 AM 페이지21 STEREO BUILT IN X-OVER ※ SETTING CHANNEL AND MASTER FADERS The final positions of the channel faders will naturally depend on the overall mix you set up. However, there are two important points you should keep in mind when setting channel levels. The channel faders have an optimum range that provides the maximum control margin with minimum noise and distortion. The optimum range for the channel faders on the PX-1650 is between about “5” and “15” on their scales.
PX-1650_E 2003.9.8 10:42 AM 페이지22 STEREO BUILT IN X-OVER ※ USING THE DIGITAL SIGNAL PROCESSOR The PX-1650 provides 16 preset effect programs, and 16 parameter variations for each preset, making for a grand total of 256 different reverbs, delays, echoes, flanging, and chorusing effects. For each program, parameter 1 provides a “standard” setting, that is, a variation that is deemed as being most characteristic of that program type.
