'Q._----------------"\
You can use the effector as an AID or DIA converter by turning off all the effects.
Analog IN/OUT and digitaliN/OUT This unit is provided with both analog and digital inputs and outputs, and you can use both of tilt'm at the same time. The input block in the SYSTEM: Setup menu lets you determine whether to usc the anall'g, the digital, or both the analog and the digital INPUT /OUTPUT jacks.
. See "Setting the DIGITAL IN/ OUT" on page 13.
Analog INPUT priority This unit is pro\'ided with both PHONE and XLR type analog INPUT and OUTPUT jacks. Although the sign,,1 is always output from both the PI lONE and XLR jacks, the PHONE jacks are gin:-n priority for the input signa I. When the PHONE and XLR INPUT jacks are used at the same time, th,' XLR signal is autl>matically cut.
. See "Names and Functions of Parts" on page 7.
Bypass and Mute The bypass function outputs the sound of the signal originally input into the effector without adding any dfl'cts. Pressing the bypass button turns the bypass function on and off. "Mute" is also ,wajJable as a form of bypass. When the BYPASS button is set to mute, the sound of the originally signal is cut in "ddition to th" sound of th<l eff<lcts. Th"rcfor", no sound comes from thl' unit. You can set BYPASS button to operate ,1S either "Mute" or "llypass" in the SYSTEM: Setup menu.
. See "Names and Functions of Parts on page 6. See 'Outputting Without Effects (BYPASS/MUTE)" on page 15 to set the bypass mode.

'Q'--------------"\

Muting the sound is more than just turning the volume to "0." It is designed to prevent sound from returning to the mixer when the unit is connected in a sendreturn loop with a mixer. Ideally. when this unit is connected to a mixer. the sound of the input signal is should not be output from this unit, only the sound of the effects should be output (see "Cutting the Direct Sound (Dry On/Off)" on page 25). In this situation, however, using bypass only cuts the sound of the effects. and the sound input into the effector goes back to the mixer, producing a double signal. Using mute prevents the sound input into the effector from returning to the mixer and insures that only the sound generated from the original source (guitar, keyboard, etc.) reaches the mixer. In other words, it is the same as bypass.

Hooking Up
Before connecting this unit to another device, be sure to unplug the AC power cord from the power outlet. Turn off the power switch on this unit and all components to be connected, such as keyboards and active speakers (speakers with built in amplifiers).

DIGITALIN

By taking advantage of the DPS-V77's DIGITAL 110 connectors, you can make digital recordings on OAT recorders, input digital signals from CD, and make digital connections to mixers (see page 29).
After all the connections, double check that the connections are correct before plugging the AC power cord back into the power outlet.
If the connected components output large signals that cause distortion, adjust the INPUT knob on this unit to lower the input level, or lower the output level of the connected component.
