Audiolab 8000AP – Pre-Amplifier
1. HDMI circuit.
The HDMI is a discrete section included as standard, which features 2 x HDMI inputs – fully HDMI1.2
compliant and certified to HDMI 1.3 - and a single output. The audio streams are read from the HDMI
data and passed to the DSP section of the processor for subsequent decoding and D/A conversion.
Both inputs and the outputs are fully HDCP compliant and are capable of all video resolutions up to
and including 1080P. The HDMI signal sent to the display is an exact replica of the signal fed into the
machine.

8 Channel analogue volume control
A high quality digitally addressed, analogue volume control is applied at the end of the output stage.
This volume section is either fed from the post DAC active filters, or directly from the 5.1 bypass
inputs if these are used. In the event that the 5.1 bypass inputs are used, the signal purity is fully
retained with a direct path, bypassing all processing circuitry.
3.
Analogue input circuits
The 8000AP has provision for up to six line level analogue inputs and a 5.1 bypass input - which
connects directly to the analogue volume control (2). All standard analogue inputs can be fed into the
DSP and encoded by a variety of processing modes including Dolby Pro Logic II, Dolby Pro Logic IIx
and all versions of DTS NEO:6.
4.
Power supply
A high quality ‘torroidal’ transformer, linear power supply is used for the 8000AP. The PCB design
ensures that there is minimum electromagnetic interaction with any sensitive components. A series of
quick-blow fuses protect the circuit from high in-rush currents or power spikes.
5.
The OSD (On Screen Display)
The OSD section allows full control of all menu functions of the 8000AP. A separate composite output
carries this menu, allowing configuration of inputs, speaker sizes and distances, HDMI decoding
options, and bass management. In addition to the OSD menu, the remote control acceses a
‘Quickset’ menu which allows the user quick and easy calibration of all essential functions.
