SM Pro Audio AB8: Analog to ADAT Converter - Handbuch (Seite 4)

2. INTRODUCTION
Using our popular and proven ADAT interface we have created the AB8. Being used by
the majority of audio card and mixing console manufacturers, the ADAT interface presents
a simple way of expanding audio inputs into most pieces of audio equipment made today
including, digital desks, digital snakes, broadcast audio gear and standard desktop audio
interfaces.
The AB8 represents a great way of converting 8 line level inputs to the ADAT format. Ba-
lanced or unbalanced the audio signal travels thru our own high quality transformer iso-
lated inputs and then via a passive attenuation circuit. The signal is then digitally
converted to the ADAT format. A word clock interface is also provided for easily syncing
to external devices.
A great tool for increasing your audio inputs where ADAT enabled products are used.
3. THE DESIGN CONCEPT
3.1 High quality components and design
The philosophy behind SM Pro Audio products guarantees a no-compromise circuit de-
sign and employs the best choice of components.
3.2 Inputs and outputs
All inputs and outputs are secured firmly to the exterior chassis housing. This ensures ro-
bust quality and confidence in performance under all conditions.
4. AB8 FRONT panel
The panel has 8 attenuation controls, 1 power switch and 8 combo connectors.
4.1 Power Switch
Use this switch to switch the AB8 ON or OFF
4.2 Level control
The AB8 uses attenuation to control the level which is being sent first to the Analog to Di-
gital converter and then to the ADAT output. It is NOT a gain control, it can only reduce
the level of the input signal.
4.3 Combo input XLR
The XLR part of the COMBO input connector is a balanced input and as such is set at a
maximum of +4dB 0dBFS equals +22dBu. Connect any balanced equipment to this input.
Note, this is not a preamp, a microphone will probably not yield enough output level to
work with this device.
4.4 Front Panel Combo line input (1/4” 6.5mm Jack)
Use this connector for devices which are not balanced such as standard line level equip-
ment. -10dBv, 0dBFS equals +8dBv (Jack)
