XL48 Microphone Pre-amplifier
2. Getting Started
This section shows you how to unpack, install, connect up, power up and
configure the XL48 unit.
◊
This equipment is supplied by a mains voltage that can cause electric
shock injury.
◊
Before installing, setting up or operating this equipment, make sure
that you have read and fully understand all of this section and the
“Important safety instructions” at the front of this manual.
2.1 Unpacking
Carefully unpack your XL48 equipment package.
Then, inspect the XL48 unit carefully for any signs of damage that may have
occurred during transit and notify the courier immediately if you discover any.
Check the contents of your XL48 equipment package. If there are any parts
missing, incorrect or faulty, please contact your local distributor or Midas at the
address at the front of this manual.
Please retain the original packing in case you should need to return the
equipment to the manufacturer or supplier, or transport or ship the unit later.
2.2 Installation
Before installing and operating this equipment, make sure it is correctly
connected to the protective earth conductor of the mains voltage supply socket
outlet through the mains lead.
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.
Mount in rack only.
Power
◊
The supply cord must be unplugged to ensure complete
de-energisation of the unit.
The internal power supply is of the switch mode type that automatically senses
the incoming mains voltage and will work where the nominal voltage is in the
range 100VAC to 240VAC.
A mains inlet is provided on the rear panel. The correct lead for connection in
the area to which the unit was shipped is supplied with the unit. The equipment
should only be plugged into the mains outlet using the supplied lead.
Handling the equipment
When lifting or moving the equipment, always take its size and weight into
consideration.
Completely isolate the equipment electrically and disconnect all cables from the
equipment before moving it.
Do not insert your fingers or hands in any gaps or openings on the equipment,
for example, vents.
electric fields
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 (20 Hz to 20 kHz), 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 (3 V/m, 90% modulation).
2.3 Connecting up
Connect up the rear panel of your unit as required:
•
Inputs:
•
XLR mic/line inputs (up to eight).
•
Parallel analogue inputs (eight).
•
External word clock.
•
Outputs:
•
AES3 outputs. There are two sets of eight AES3 mono output channels
(1 to 8), one set are on connectors 1 to 4 and the other set are on
connectors 5 to 8.
•
Analogue outputs (eight).
•
ADAT outputs (optional) — for connecting, for example, a sound
card (for PC) or an ADAT recorder. At 44.1kHz and 48kHz sample
frequencies the two ADAT ports are identical and both provide eight
output channels (1 to 8). At 88.2kHz and 96kHz sample frequencies,
both ports provide four output channels each (port 1 = channels 1 to 4
and port 2 = channels 5 to 8).
•
Internal word clock.
•
Mains power
— connect the IEC connector of the mains cable into the rear
of the unit and then plug it into a mains power outlet.
2.4 Powering the unit on/off
As the XL48 has no power on/off switch the unit is powered on/off via the
mains outlet.
2.5 Configuration
After you have powered up the XL48 you can configure the clock source and
sample rate as required.
