than the converter that takes your original analog input signal

and converts it into digital information. The higher the quali-

ty of the A/D converter, the better the sound. It's as simple as

that. So when we decided to create a new conversion system, we

knew we had to listen – and listen hard.

Apogee's engineering team worked with Apogee's Advisory

Board, which includes some of the top names in the

industry. Each contributed ideas and suggestions from

Soft Limit:

Apogee's proprietary Soft Limit

circuitry, available on every channel of the

AD-8000, enables you to get more level on to

tape without risking digital "overs".

The result was the AD-8000 – a conversion system truly

without parallel.

The AD-8000 takes digital conversion to a whole new

level. It's a true 24-bit converter, with 114 dB dynamic

All interfaces are

available at all times, enabling you to use the

AD-8000 as a powerful multi-channel digital

format converter—a feature worth thousands

on its own. Convert from any interface to all

others simultaneously, whether they are

inbuilt or on AMBus cards.

or have a project setup in your garage, the AD-8000 was created

with you in mind.

Every facet of the AD-8000 was designed by industry profes-

sionals – from Apogee's proprietary UV22

multi-mode bargraph metering; from the innovative front panel to

the four-slot AMBus card bay supporting virtually any interface.

Hear the Apogee advantage for yourself. Just visit your Apogee

dealer and try out the AD-8000. You'll notice the difference

immediately. Whatever your recording environment, the converter

is the heart of your digital system. Now, with the Apogee AD-8000,

an outboard converter is no longer an option. It's a necessity.

Digital Routing:

With the AD-8000's

unique digital routing matrix, choose sources

and destinations for all your signals at the

push of a silver button. AMBus slots with

cards installed are identified for instant

access. Combinations of analog and digital

inputs may be selected simultaneously.

Overdub (Destination) Mode:

Any

device connected to an AMBus card can be

monitored while it is the output destination

of the AD-8000, to permit overdubbing and

confidence monitoring. The output of the

selected card is also available at all other

interfaces and any installed D/A card.

Available AMBus cards provide

additional interfaces including

ADAT Optical (shown here),

AES and TDIF (Tascam),

with "bit-splitting"

technology

for recording

20/24-bit

signals on

multiple 16-bit

tracks. Other available

interfaces include cards

providing direct connection to a
