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 7-

channel 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 bit-

stream 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.

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.

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.
