5 ULTRAGAIN PRO-8 DIGITAL ADA8000 User Manual
◊ Please mute your amplifier(s) before activating the phantom
power. Otherwise, switch-on thumps may be audible on your
loudspeakers/headphones.
(9) The POWER switch powers the ADA8000 on. You should always make sure
that the POWER switch is in the “O” position when initially connecting the
unit to the mains.
◊ Please take note: Merely switching the unit off does not mean that
it is fully disconnected from the mains. When not using the unit for
prolonged periods of time, please unplug the unit’s power cord from
the power outlet.

(10) FUSE COMPARTMENT / VOLTAGE SELECTION. Before connecting the unit
to a power outlet, please make sure that the selected voltage matches your
local voltage. When replacing fuses, please make sure that you always use
fuses of the same type. Some units allow for switching between 230 V
und 120 V. Please note: when connecting a unit intended for the European
market to a 120 V power outlet, you must also replace the factory fuse with a
higher-value fuse.
(11) Power is supplied via an IEC connector. The matching cable is provided with
the unit.

Fig. 2.3: ADAT IN/OUT and wordclock SYNC
(12) All analog input signals are converted into the standard ADAT format and can
be taken at the 8-CHANNEL DIGITAL OUT. This output can be used to feed
an ADAT recorder or any other device featuring an ADAT input. Please note
that a signal present at the Digital In will not be routed to the Digital Out.
(13) At the 8-CHANNEL DIGITAL IN, you can connect an ADAT device. The signal
will automatically be routed to the 8 analog LINE OUT connectors.
(14) Use the WC IN connector to connect devices for the external synchronization
of your ADA8000. This BNC connector is only active, whenthe respective
setting on the rear is made (see (15)). When,forexample, various devices
are interconnected in a digital recordingsystem with, say, adigital mixing
console, all digital units connected have to be synchronized via a shared
wordclock signal.
(15) The setting of this switch depends on the application of your ADA8000. If an
external ADAT recorder is supposed to send the wordclock signal (in this case,
the ADA8000 functions as SLAVE), the switch has to be set to the ADAT IN
position. Please also note the instructions given in the user’s manual of your
ADAT device. When your ADA8000 functions as Master (here, the ADA8000
sends the wordclock signal) please use the switch to select the sampling rate
of your choice (either 44,1 or 48 kHz).
(16) Your ADA8000 features eight LINE OUTs on balanced XLR connectors.
An input signal present at the ADAT IN will automatically be transferred
into eight independent signals and routed to the eight analog
LINEOUTconnectors.

3. Applications
Your ADA8000 is an ideal expansion for BEHRINGER’s digital mixing console
DDX3216, which features an optional ADAT interface. Thanks to the ADA8000,
thisdigital mixer can be expanded by eight additional analog inputs and
outputs. Sound cards featuring ADAT INs and OUTs receive eight rst-class analog
inputs and outputs with the ADA8000. What’s more, the eight “Invisible” Mic
Preamps perfectly enable direct recording to digital multitrackers (e.g. ADAT).
Lastbut not least, you can also use the ADA8000’s audio channels to create a live
surroundmix.
4. Audio Connections
You will need many dierent cables for the various applications. The following
illustrations show how these cables should be laid out.
Please use exclusively high-grade cables. The audio connectors of your ADA8000
are electronically balanced and ensure automatic hum and noise reduction.
Needless to say, even devices with unbalanced outputs can be connected to
the balanced in/outputs of your ADA8000. For this purpose, please use either
mono plugs or connect the ring of stereo plugs with the sleeve (when using XLR
connectors, pin 1 and pin 3 have to be bridged).
◊ Please ensure that only qualified personnel install and operate the
ADA8000. During installation and operation the user must have
sufficient electrical contact to earth. Electrostatic charges might affect
the operation of the unit.
