Playing a USB input

Install the Audiolab Audio Driver from the CD-ROM provided as accessory. The

installation instructions are burnt on the CD-ROM, please refer to the file when

installing the software. Connect your computer to 8300CD via USB cable (type A

to Type B), change the Play mode to USB input using the handset or the button on

the front panel.

"Unlocked" will be displayed if no input signal for USB. The Play with digital

inputs will lock onto the input data when there is an input signal for USB. The

display screen will then indicate the presence of a digital signal and show the

output sampling frequency of the music file in your computer.

If input sampling frequency is 384kHz, display shows PCM384 kHz.

If the format of music file is DSD64, display shows DSD2.8MHz.

If the format of music file is DSD128, display shows DSD5.6MHz.

If the format of music file is DSD256, display shows DSD11.2MHz.

Selecting the Display brightness level

Pressing the DISPLAY button on the remote control cycles through the display

settings.

Press the DISPLAY button to select between Display High, Display Low and Display

Off. Each press of the DISPLAY button will select the next display setting.

When the display is OFF: Pressing any key will momentarily switch the display on.

After a few moments the display will go off.

The "Optimal Transient" filters exhibit no ringing – the transient nature of

the music is preserved. Although exhibiting poorer performance in technical

measurements, sound from this type of filter has a purity and "naturalness" that

more than compensates for the lack of the technical specifications. There are

three Optimal Transient Filters. They exhibit identical frequency and time domain

response but the internal structure of the filters varies. Resulting in small but the

perceptibly different sonic nuances.

The "Sharp Rolloff" filter typifies industrial standard characteristics ( -6dB at 1/2

Fs with significant time-domain ringing ) and is included here for comparison

purposes.

The "Slow Rolloff" filter starts rolling off at a lower frequency then the Sharp

Rolloff filter but has a gentle rate of attenuation and significantly less "time-domain

ringing". This filter is not recommended to use normally, unless the difital signal

from source is very poor can't play with other filters.

The "Minimum Phase" filter has a gentle attenuation slope similar to the Slow

Rolloff option, however it exhibits no pre-ringing in the time domain. It can be

likened to an analogue filter applied in the digital domain.

The "Optimal Spectrum" filter implements sampling theory and is designed for

near perfect technical response in the frequency domain. This filter also has time-

domain pre-ringing which can lead to listener fatigue.

For DSD mode, there are four filters "Normal", "50K", "60K" and "70K" which

with cutoffs at 47k, 50K, 60k, 70k. End user can adjust the IIR bandwidth via

selecting different filters to get favorite sonic nuances.

The Audiolab products uniquely offer you a wide choice of filters to meet your

listening expectation.
