Precautions
Before installing, setting up or operating this equipment make sure you have read and
fully understand all of this section and the “IMPORTANT SAFETY INSTRUCTIONS” at the
front of this manual.
This equipment is supplied by a mains voltage that can cause electric shock injury!
The following must be observed in order to maintain safety and electromagnetic compatibility (EMC)
performance.
Safety warnings
Signal 0V is connected internally to the
chassis.
To electrically isolate this equipment, while
observing full safety precautions (see
“Power” below), switch off the two isolator
switches (above the mains sockets on the
rear panel of the unit) one at a time and
then switch off the mains at the two mains
outlets. Isolate the unit by unplugging the
two mains leads from rear panel.
To avoid electrical shock do not remove
covers.
General precautions
In the event of ground loop problems,
disconnect the signal screen at one end of the
connecting cables. Note that this can only be
done when the equipment is used within a
balanced system.
Do not remove, hide or deface any warnings or
cautions.
Power
distributed so as to meet local safety
regulations.
A Volex locking type plug is fitted on each
supplied mains cable, which plugs into a mains
IEC connector on the unit. When fitted properly
the Volex plug locks into place, preventing it
from working loose, or being inadvertently
knocked loose or pulled out. To fit a Volex plug,
insert it into the mains IEC connector and push
it in until it locks in place. Then, check to make
sure it is locked in place. To remove it, release
its locking device and then pull it out. When
fitting or removing a Volex plug, always hold the
plug itself and never use the cable, as this may
damage it.
When removing the equipment’s electric plugs
from the outlets, always hold the plug itself and
not the cable. Pulling out the plug by the cable
can damage it.
Never insert or remove an electric plug with wet
hands.
Do not connect/disconnect a mains power
connector to/from the unit while power is being
applied to it. Switch the power off first.
Switch the mains isolator switches on/off one at
a time. Do not switch them both on/off
simultaneously.
The power supplies contain LETHAL VOLTAGES
greatly in excess of the mains voltage and its
rails can produce extremely large currents that
could burn out equipment and wiring if shorted.
The internal power supplies are of the switch
mode type that automatically sense the
incoming mains voltage and will work where the
nominal voltage is in the range 100VAC to
240VAC.
Each mains inlet is to be sourced from its own
separate wall-mounted mains outlet socket.
Otherwise, their mains sources must be suitably
DL351 Modular I/O
Operator Manual
Handling the equipment
Completely isolate the equipment electrically
and disconnect all cables from the equipment
before moving it.
When lifting or moving the equipment, always
take its size and weight into consideration. If
necessary, use suitable lifting equipment or
transporting gear, or sufficient additional
personnel.
xii Precautions
Do not insert your fingers or hands in any gaps
or openings on the equipment, for example,
vents.
Installation
Before installing the equipment:
• Make sure the equipment is correctly
connected to the protective earth conductor
of the mains voltage supply of the system
installation through the mains leads.
• Power to the equipment must be via a fused
spur(s).
• Power plugs must be inserted in socket
outlets provided with protective earth
contacts. The electrical supply at the socket
outlets must provide appropriate
over-current protection.
• Both the mains supply and the quality of
earthing must be adequate for the
equipment.
• Before connecting up the equipment, check
that the mains power supply voltage rating
corresponds with the local mains power
supply . The rating of the mains power supply
voltage is printed on the equipment.
XLR connector shells should be of metal
construction so that they provide a screen when
connected to the control centre and, where
appropriate, they should have Pin 1 connected
to the cable screen.
Radio frequency interference—Class A device
This equipment has been tested and found to
comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference when
the equipment is operated in a commercial
environment. This equipment generates, uses,
and can radiate radio frequency energy and, if
not installed and used in accordance with the
instruction manual, may cause harmful
interference to radio communications.
Operation of this equipment in a residential area
is likely to cause harmful interference in which
case the user will be required to correct the
interference at his own expense.
Electric fields
Location
Ideally a cool area is preferred, away from
power distribution equipment or other potential
sources of interference.
Do not install the equipment in places of poor
ventilation.
Do not install this equipment in a location
subjected to excessive heat, dust or mechanical
vibration. Allow for adequate ventilation around
the equipment, making sure that its fans and
vents are not obstructed. Whenever possible,
keep the equipment out of direct sunlight.
Do not place the equipment in an unstable
condition where it might accidentally fall over.
Make sure that the mains voltage and fuse
rating information of the equipment will be
visible after installation.
Audio connections
To ensure the correct and reliable operation of
your equipment, only high quality, balanced,
screened, twisted pair audio cable should be
used.
Caution:
In accordance with Part 15 of the FCC
Rules & Regulations, “… changes or
modifications not expressly approved by
the party responsible for compliance could
void the user's authority to operate the
equipment.”
Should this product be used in an
electromagnetic field that is amplitude
modulated by an audio frequency signal (20Hz
to 20kHz), the signal to noise ratio may be
degraded. Degradation of up to 60dB at a
frequency corresponding to the modulation
signal may be experienced under extreme
conditions (3V/m, 90% modulation).
Safety equipment
Never remove, for example, covers, housings or
any other safety guards. Do not operate the
equipment or any of its parts if safety guards
are ineffective or their effectiveness has been
reduced.

Features
The DL351 Modular I/O has the following features:
• Up to 64 analogue/digital audio inputs or outputs.
• Sub-modular construction provides user-configurable 8 x 8-channel format.
• The front panel has minimal controls, which are used in conjunction with a standard
16-column x 2-row LCD display.
• Fully isolated GPIO in and out connections supplied as standard, via 25-pin
D-type connectors.
• in, out and thru MIDI sockets supplied as standard, via 5-pin DIN connectors.
• N+1 redundant AES50 connections provided at the digital audio interface.
•USB host and slave ports provide additional communications interfacing.
• System interconnection is via four AES50 (24 bi-directional digital audio channels)
on EtherCon® XLRs (connection is to the router module), which provides N+1
capability.
• All AES EBU connections, analogue inputs and analogue outputs are provided by
3-pin XLR chassis connectors.
• Remote interrogate LEDs are adjacent to the physical XLRs. These are controlled
ultimately from the digital console control surface and serve as a visual aid when
seeking a particular connector.
• The analogue inputs incorporate remotely controlled, 5dB step analogue gain
adjustment from –5dB to +40dB and Phantom power (with LED status).
• The analogue signal maximum incorporates “Clean Clipping” to ensure A/Ds are
never clipped.
• The A/D and D/A converters are 24-bit and sampled primarily at 96kHz.
• The A/D inputs take a maximum signal level that represents external +22dBu, that
is, 0dBFS (0dB full scale).
• Each of the DC rails is fitted with suitable fusing elements, such that a single board
failure will not bring the whole rack down.
• The unit offers the facility of universal input, dual redundant power supplies with two
latching mains connectors.
• The unit is force air cooled by means of 80 mm fans. These produce low noise,
which is suitable for concert sound. However, racking in separate “amp rooms” is
advised for theatre use.
