Audiolab 8000AP – Pre-Amplifier
High End Digital Audio Processor with HDMI
IAG are proud to announce the launch of the new generation Pre amplifier – 8000AP from
Audiolab. The new HDMI enabled 8000 series ‘Audio Processor’ is a reference quality 7channel audio processor and preamplifier.

“An Audiophile approach to home cinema”

The Audiolab 8000AP offers superb quality audio processing and switching with capacity
for stereo and multi-channel analogue sources, co-axial and optical digital inputs and twin
HDMI inputs. Multi-channel HD audio can be passed via the HDMI connections from
appropriately equipped source components.
The emphasis is on high-quality audio offering an unequalled sound quality whatever
source is used. The Audiolab 8000AP Audio processor features the latest in Digital signal
processing; A dual core Cirrus Logic™ DSP with a 24bit front end and 32bit post
processor. ‘High End’ Digital to Analogue conversion is handled by 24bit/192KHz bitstream D/A converters with differential outputs, followed by phase linear active filters and
ultra low distortion analogue volume controls.
For details, please contact your audiolab sales representative.

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.

2.

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.

6.

Post DAC Phase Linear active filters.
Phase linear active filters are utilised after the D-A conversion, using components chosen for their
excellent sonic characteristics. This moves DAC noise outside the audible spectrum, lowering the
noise floor significantly and optimises the analogue output prior to amplification.

7.

CODEC (SPDIF receiver, Stereo A/D, 8 Channel DAC)
The 8000AP uses a high quality 8 channel CODEC which includes the following features and
performance.

•

A/D converters: 24Bit / 48kHz
D/A converters: 24Bit / 192kHz
S/PDIF receiver
8 Channel SPDIF input multiplexer
Differential analogue architecture
-100 dB THD+N

8.

Microprocessor
A powerful microprocessor ensures all the component parts of the 8000AP work together seamlessly.

9.

DSP
The 8000AP uses a "Dual" DSP which integrates a multi-channel audio decoder and a 32-bit audio
processor with an audio optimised software framework. This allows the 8000AP to decode all of the
popular processing modes listed below.
