4. The minimum distance between parts carrying mains voltage and any accessible metal piece (metal enclosure),
respectively between the mains poles has to be 3 mm and needs to be minded at all times. The minimum distance
between parts carrying mains voltage and any switches or breakers that are not connected to the mains (secondary
parts) has to be 6 mm and needs to be minded at all times.
5. Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only
permissible when using original parts.
6. Altering the circuitry without prior consent or advice is not legitimate.
7. Any work security regulations that are applicable at the location where the appliance is being serviced have to be
strictly obeyed. This applies also to any regulations about the work place itself.

The DSP 260 does not itself have input level controls. Proper input level
adjustment is accomplished by setting the output level from the (L / R) bus

majority of today’s mixer-outputs are dBu calibr ated. When the mixer is operating
at optimal levels, so is the DSP 260. The input meters monitor the input level of

Each output channel has an eight-segment output level VU meter. Meter
response characteristics can be selected in the Setup menu: Normal F ast,
Peak-Hold Slow Decay. The yellow segment indicates that limiti ng is bei ng
applied to the output channel. The red segments indicates clipping of the D/A
converters and should be avoided by adjusting the Output Level of the output
channel. It is important to understand how the meters work and what they
are displaying. The Output Meters are displayed as “dB to Limiter Threshold”.
In other words, these meters will display the headroom between the output
level and the limiter threshold. When viewe d in co n ju n ction with the Gain
Reduction meters, this provides a complete display of level and headroom
before and after limiting has been engaged to allow system levels to be
o
timized.
This also means that the output
metering will be displayed differently
depending on the limiter threshold setting.

23 – Output Channel Function Indicators
Each output channel has a four-segment function display for informational
purposes only . F or any given configuration possible with the DSP 260, an
output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or
full range output. One or two adjacent LED are displayed to indicate all
ossible output bandpasses.
Full range is indicated b
The DSP 260 features a standard IEC A.C. inlet that will accept universal
power cords. The DSP 260 power supply is auto-ranging and can accept
voltages from 100 - 240VAC, 50 – 60Hz. Only A.C. cords approved for use in
our country should be connected to the DSP 260.
The A.C. inlet includes a fuse holder that contains the mains fuse as well as a
spare fuse. If necessary, replace the fuse only with a specified 5x20mm,
T800mA, L250V replacement. Disconnect A.C. power before replacing a fuse.
Before turning the unit back on, assess the condition of the A.C. receptacle
powering the DSP 260. If fuses continue to blow, refer servicing of the DSP
260 onl
The A.C. power switch turns
ower to the DSP 260 On and Off.
The operating mode of this dual purpose interface is selected in the Setup
menu. O
nterface – Used to link two DSP 260s together in a Master /
Slave setup. Connection is made via a standard 9-pin null-modem serial
interface cable with fem al e connectors.
Closure Port – Eight contact closure pins plus ground for
interfacing to 5 V contact closure systems. Each pin can be assigned a
preset that is recalled when voltage on that pin is detected. The lowest
multiple controller systems.

28 – Balanced XLR Outputs
Each output channel has an electronically balanced XLR connector for
connection to system amplifiers. Each output channel can output different
frequency ranges dependin
its assignment and cross-over settings.
en to assure that each output is connected
to an appropriate amplifier and loudspeaker to avoid damage
or unexpected results. Note that a new preset may change
the assignment of channel and its frequency range. For
instance an output assigned to Hi frequency speakers in one
preset, may be assigned as a sub output in another. See
Configurations of the DSP 260”.
29 – AES/EBU Digital Input
In addition to the analog audio inputs, an AES/EBU digital stereo input is
provided and selectable in the Setup menu. The input conforms to IEC
standard 60958 Type I. Connections must be made with three-conductor,
110-Ohm, twisted pair cablin
Each analog audio input is connected to an electronically buffered and
balanced output as a through connector. The signal does not undergo any
digital conversion or processing. These connectors are used to pass input
audio to a second DSP 260 used as a slave or to other audio inputs in the
s
stem.
31 – Balanced XLR In
Each input has an electronically balanced, locking XLR connector. In stereo o
dual modes, connections to both inputs must be made. In mono modes, onl
one connection need be made
Input levels to the DSP 260 can be reduced -6dB prior to the A/D converter t
compensate for higher-level output from mixers and other audio devices. Fo
ideal signal to noise performance when connecting the DSP 260 to high outpu
level devices engage the -6dB pad rather than turning down the output of th
connected device. The DSP 260’s Input Level Meters (2) will indicate incoming
si
nal level and whether attenuation is required.

Installation
For proper operation, all directions regarding installation and connection must be
followed.
Mounting
The DSP 260 should be mounted in a rack-mount enclosure or rack rails. The
unit is 1RU tall by 14” (353mm) deep. Proper clearance for air circulation
around the unit must be provided. Do not block any vent holes on the unit.
For secure mounting and electrical insulation, correct r ack screws must be
used – #10-32 screw with plastic / nylon cup washer. All four mounting points
provided by the rack ears must be secured.
Power Connection
The DSP 260 must be connected to A.C. power only by means of the provided
IEC A.C. cable or by a power cable provided by the dealer / installer to match
the configuration of your country or region. The DSP 260 must only be
connected to a properly wired, three pin, grounded A.C. outlet. A.C. power
must range from 100 – 240VAC, 50 – 60Hz. The DSP 260 internal power
supply is an auto-ranging design; no adjustments are necessary to configure
it for proper A.C. power.
Audio Cables
Always use correctly shielded audio cables when connecting to the DSP 260.
Balanced Input / Output Connectio ns
To minimize induced noise caused by audio cables and to maximize the length
of cables used, balanced connections are strongly advised for both Inputs and
Outputs. The XLR jacks provided on the DSP 260 are configured as pin 1
ground, pin 2 hot (+), pin 3 cold (-). Cable shielding must be connected to
pin 1. XLR – XLR cables or ¼” tip-ring-sleeve – XLR cables can both be used
for balanced connections to the DSP 260.

Un-balanced Input / Output Connections
Un-balanced connections can be made to the DSP 260, although induced
noise from cabling may be increased. Cables should also be less than 15”
(5m) in length. Unbalanced connections can be 6dB lower in level as well. To
match the audio level obtained with a balanced connection, it is necessary to
tie pin 3 to ground at the XLR connector. This may increase noise.
RS-232
Two DSP 260s can be used in combination as a
Master / Slave for managing larger sound
reinforcement systems. A 9-pin D-sub connector is
provided on the rear of each unit for data line
connections. A standard female-to-female RS232
cable that conforms to the null modem wiring
convention is used to connect the two units. Cable
length should be kept to less than 45 feet (15m) for
the most reliable operation. These cables are readily
available at lo cal computer dealers.
the DSP 260 9-pin port for RS-
232 connections is selected in the Setup menu.
Relay Contact Closure
The same 9-pin port used for RS-232
connection to another DSP 260 can
alternately be used to recall presets
from relay contact closures. Pins 1 – 8
are the input lines and pin 9 provides
the ground reference. When the DSP
260 detects a connection between pin-9
ground and pins 1 – 8, as completed by
an external relay, a preset assigned by
the user to pins 1-8 is recalled into
memory and the DSP 260 returns to
runtime mode.
