4 ULTRAGAIN PRO-8 DIGITAL ADA8000 User Manual
1. Introduction
Your ADA8000 is a state-of-the art 8-channel A/D and D/A converter. This ultra-
compact 19" unit gives you the opportunity to connect analog audio signals
directly to, say a multitrack recorder via the integrated ADAT interface. For this
purpose, the ADA8000 deserves one rack space only. In return, you can even
connect the digital signal of a multitracker via ADAT to the eight analog line
outputs of your ADA8000. Signal conversion can be processed at 44.1 or
48 kHz with 24-bit resolution. The ADAT inputs and outputs can be operated
independently as long as there is an identical wordclock signal. The integrated
A/D and D/A converters ensure optimal signal conversion without any distortion
or signal deterioration.
IMP “Invisible” Mic Preamp
The microphone channels are fitted with BEHRINGER’s brand new high-end
IMP INVISIBLE MIC PREAMPs that boast the following features:
130 dB dynamic range for an incredible amount of headroom,
• a bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear
reproduction of even the finest nuances
• the extremely low-noise and distortionless circuitry gua rantees absolutely
natural and transparent signal repro duction
• they are perfectly matched to every conceivable micro phone with up to
60 dB gain and +48 volt phantom power supply and
• they enable full utilisation of the greatly extended dynamic range of your
24-bit/192 kHz HD recorder, thereby main taining optimal audio quality
◊ The following user’s manual is intended to familiarize you with the
unit’s control elements, so that you can master all the functions.
After having thoroughly read the user’s manual, store it at a safe place
for future reference.
1.1 Before you get started
1.1.1 Shipment
The ADA8000 was carefully packed at the assembly plant to assure secure
transport. Should the condition of the cardboard box suggest that damage may
have taken place, please inspect the unit immediately and look for physical
indications of damage.
◊ Damaged units should NEVER be sent directly to us. Please inform the
dealer from whom you acquired the unit immediately as well as the
transportation company from which you took delivery of the unit.
Otherwise, all claims for replacement/repair may be rendered invalid.
1.1.2 Initial operation
Please make sure the unit is provided with sufficient ventilation, and never place
the ADA8000 on top of an amplifier or in the vicinity of a heater to avoid the risk
of overheating.
◊ Before plugging the unit into a power socket, please make sure you
have selected the correct voltage:
The fuse compartment near the power plug socket contains three triangular
markings. Two of these triangles are opposite one another. The voltage indicated
adjacent to these markings is the voltage to which your unit has been set up,
and can be altered by rotating the fuse compartment by 180°.
ATTENTION: This does not apply to export models that were for example
manufactured only for use with 120 V!
◊ If you alter the unit’s voltage, you must change the fuses accordingly.
The correct value of the fuses needed can be found in the
chapter “Specifications”.
◊ Faulty fuses must be replaced with fuses of appropriate rating without
exception! The correct value of the fuses needed can be found in the
chapter “Specifications”.
Power is delivered via the cable enclosed with the unit. All requiered safety
precautions have been adhered to.
◊ Please make sure that the unit is grounded at all times. For your own
protection, you should never tamper with the grounding of the cable or
the unit itself.
1.1.3 Warranty
Please take a few minutes and send us the completely filled out warranty
card within 14 days of the date of purchase. You may also register online at
behringer.com. The serial number needed for the registration is located at the top
of the unit. Failure to register your product may void future warranty claims.

Fig. 2.1: ADA8000 channel section
The ADA8000 features eight identical channels. Each section comprises
a microphone input (on a balanced XLR connector) and a line-level input
(on a balanced ¼" TRS jack). We recommend connecting only one input signal
per channel. When two input signals are connected, the weaker signal is
suppressed and will be audible as interference noise.
(1) The SIG LED lights up when a signal is present at one of the inputs.
(2) If the input level is too high, the CLIP LED lights up. The CLIP LED should
light up only with signal peaks but never all the time.
(3) Use the GAIN control to set the input gain. The gain ranges from +10 to
+60 dB. The GAIN control governs both the LINE IN and the MIC IN input.
(4) This is the balanced ¼" TRS LINE IN connector. A connected analog
LINE IN or MIC IN signal is not routed to the analog LINE OUT connector (16).
Instead, it will reach the ADAT OUT interface.
(5) This is the balanced MIC IN XLR connector. For example, you can connect
your microphone here.
(6) As long as the ADA8000 functions as master, sending a clock signal,
the SYNC MASTER LED lights up. The appropriate setting can be made on
the rear (see (15)).
(7) When the ADA8000 is synchronized externally (either ADAT or wordclock IN),
the SYNC LOCKED-LED lights up.
(8) Press the +48 V switch to provide condenser microphones which are
connected to the MIC IN inputs with the required phantom power.
Dynamic microphones do not require this external power supply. When the
switch is depressed, phantom power is active on all inputs.
