IMPORTANT
The wires in this mains lead are coloured in accordance with
the following code:
Green-and-yellow: Earth
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured markings
identifying the terminals in your plug proceed as follows:
The wire which is coloured green-and-yellow must be
connected to the terminal in the plug which is marked by the
letter E or by the safety earth symbol + or coloured green or
green-and-yellow. The wire which is coloured blue must be
connected to the terminal which is marked with the letter N
or coloured black. The wire which is coloured brown must be
connected to the terminal which is marked with the letter L
or coloured red.
Precautions
On Safety
e To avoid electrical shock, do not open the cabinet. Refer
servicing to qualified personnel only.
e Before connecting the unit to the power source, check that
the operating voltage of your unit is the same as the local
power line voltage. The operating voltage is indicated on
the nameplate on the left side of the unit.
« Should anything fall into the cabinet, unplug the unit and
have it checked by qualified personnel before operating it
any further.
e If the unit will not be used for an extended period, unplug it
from the wall outlet. To disconnect the cord, pull it out by
the plug. Never pull the cord itself.
e The unit is not disconnected from the mains (AC power
source) as long as it is connected to the mains outlet, even
if the unit itself has been turned off.
suolnesaig /HuWweR
On Installation
e Allow adequate air circulation to prevent internal heat build-
up.
e Do not place the unit on a surface (rugs, blankets, etc.) or
near materials (curtains, draperies, etc.) that may block the
ventilation holes.
e Do not install the unit near heat sources such as radiators
or air ducts or in a place subject to direct sunlight,
excessive dust, mechanical vibration or shock.
e The unit is designed for operation in a horizontal position.
Do not install it in an inclined position.
e Keep the unit away from equipment with strong magnets,
such as microwave ovens or large loudspeakers.
«Do not place any heavy object on the unit.
On Operation
e When the unit is not in use, turn the power off to conserve
energy and to extend its life.
On Cleaning
e Clean the cabinet, panel and controls with a dry soft cloth,
or a soft cloth slightly moistened with a mild detergent
solution.
e Do not use any type of solvents, such as alcohol or
benzine, which might damage the finish.
On Repacking
e Do not throw away the carton and packing materials. They
make an ideal container to transport the unit.
If you have any questions about the unit, contact your Sony
service facility.

Overview of the DPS-R7
The DPS-F7 is a digital reverberator equipped entirely with
Sony’s digital and audio technology at its highest level of
sophistication which was released before with the Digital
Reverberator, DRE-2000 and MU-R201 and achieved much
appraisal.
Quality-conscious design - A/D and D/A high
performance converter
The DPS-R7 converts the incoming analog signal to a digital
signal, passes it through various effects, then
re-converts it to an analog singnal before output. The
determinant to the sound quality is the conversion
mechanism that adopts the 18-bit oversampling stereo A/D
converter and the pulse D/A converter of 40.96 MHz. These
account for highly accurate, less deteriorated effects.
User-friendly and comfortable operation
The large size backlit LCD of 40 characters by 2 lines makes
it possible to proceed with smooth operation while viewing
the operating condition in real time. Moreover, the LCD
display incorporates an on-line manual (in English) which
displays information required for operation.
Abundant preset memory settings
The unit has a hundred variations of the effects created by
musicians, sound mixers and acoustic engineers around the
world in its preset memory. This will help you select and
replay immediately the desired effects for a particular
purpose.
Sound creation of any kind
The EDIT function allows you to modify the presets or to
create some individual effects. Besides the preset memory
for a hundred effects, the unit has a so-called user memory
where you can save up to 256 effects you are going to
create. Using this memory allows more varicolored play of
effects,
Wide range of effects
The DPS-R7 consists mainly of a reverberation block
together with an input block, a pre-effect block, a post-effect
block and an output block for signal processing.
For Processing signals with stereo-input/stereo-output in the
reverberation block, one of 5 types of ST-ST algorithms is
available, while the monaural-input/stereo-output processing
allows you to take any two types of MONO-ST algorithm.
One of the six types of algorithms can be used in the pre-
effect block and one of seven in the post-effect block.
By combining these blocks and algorithms used in the
blocks, a wide range of effects will be able to be created
according to the input source.
Remote control
The remote commander (not supplied) makes it possible to
remotely control the unit.
2 types of I/O connectors are provided
The DPS-R7 has XLR connectors (balanced-type) and
phone jacks so that it can be connected to instruments,
recording equipment or PA (public address) equipment.
Linkage with MIDI equipment
The MIDI device incorporated in the DPS-R7 can receive
program change signals from another MIDI equipment
connected so that the DPS-R7 can be controlled by the MIDI
equipment connected. Thus, it can function as an effector
when connected to digital instruments. In addition, controls
from PC’s or MIDI sequencers are very helpful for
composition.
