Turning on the power on recalls the last used memorized effect and activates play mode automatically. 2 INPUT level adjustment knob Turn the knob to the left or right to adjust the input level. Adjustments can be made independently for each channel.
Understanding the Signal Flow This unit takes in audio signals from two types of input jacks (digital and analog), processes them using various internal blocks, and outputs them through the analog and digital output jacks. To make the most of this unit, it is essential that you have a firm understanding of the audio signal flow. This section provides an explanation of the internal blocks and how they process the input and output audio signals. PARALLEL '(PARA) C~NI~'1 Bl~CK l-fl ~IX ,.
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. Analog INPUT priority This unit is pro\'ided with both PHONE and XLR type analog INPUT and OUTPUT jacks.
Hooking Up 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). • 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).
Choosing an Effect Recalling Effects from the Memory Outputting Without Effects (BYPASS/MUTE) You can use the following procedure to select effects from The effector comes with 198 different effects stored in the either the preset memory or the user memory banks. preset memory as well as a 198 effect memory capacity for storing the effects you create.

SECTION 2 TEST MODE • This product uses a microcomputer and is equipped with a· MIDI interface for musical instruments and computers, and it has specifications that make possible rewriting of the internal memory with external MIDI equipment. Due to this, when required, the internal data can be rewritten by the use of external equipment, etc., and in case the internal data.should break down at the time of repair (Example: when the power is cut oft), it may happen that the operation becomes unstable.
Operation and Display Subject • Others 5) Other checks • Other error messages are displayed in 1. [DRAM1 ERR] or [DRAM2 ERR] Automatic inspection of the soldered bridge, etc., of IC601, IC602, IC603 is carried out. If this display appears, apply a soldering iron to the terminal of each IC and check the application of the solder. In case of [DRAM1 ERR], check IC601 and IC602, and in case of [DRAM2 ERR], check IC603 and IC604.
