The 16 bit/44.1kHz sampling data on a standard CD is upsampled to 24

bit/384kHz for best possible sound quality.

Digital Input 1/2

Press 

Select

again to select Digital Input 1.

The incoming word length (16 to 24 bit) and sample rate will be

displayed along with the indication that the data is being upsampled to

24 bit/384kHz. Note that rather than exact word width, some sources

report data as either 20 bit maximum (displayed as < = 20) or 24 bit

maximum (displayed as < = 24).

If no digital signal is present, the display will show “UNLOCKED” and the

output will be muted.

Press 

Select

The 740C has a custom-made display on the front of the unit showing

the current status and allowing access to the 740C System

Configuration menus. The 740C features some advanced settings that

allow its use to be customised to user preference.

Menu structure

Press the 

Menu

button to scroll through the menus, then use the 

Select

button to scroll through the options/sub menus of that menu. Press the

Menu

button again to move to the next menu, or after a few seconds the

display will return to the default main menu.

Digital outputs

The digital outputs can be set to two options:

1. Output the raw data from the CD (or digital input) with no processing.

2. Upsampled data processing by the DSP to greater resolution. 

Press 

Select

to switch between DSP Upsample or Pass Through.

For DSP upsampling the sample frequency, word width and dither are

set by the next three available menus. 

Digital out sample frequency

The digital output sample frequency (note this is different to the main

audio output sample frequency which is fixed at 384kHz for best sound

quality) can be set to 48, 96 or 192kHz (the maximum frequency

supported by SPDIF/Toslink):

Press 

Select

to switch between the frequency options. 

Digital out word width

The digital output word width can be set to 16, 20 or 24 bit (note this is

different to the main audio output word width which is fixed at 24 bit for

best sound quality):

Press 

Select

to switch between the word width options.

Digital out dither

Dithering is a process where pseudo random noise is added to a signal

to remove quantisation effects that cause harmonic distortion and

replace them with a slightly increased noise floor. The process can

improve the perceived quality of digitised audio signals as a small

decrease in signal to noise ration (especially where the noise is random)

is much preferably to harmonic distortion to the human ear.

The 740C is able to add what is called Triangular Probability Density

Function dither to the upsampled Digital Output signals. Normally, dither

will have already been added to any CD or source material during its

mastering process so the default for this option is off. However if a

source with no dither is used (perhaps an off board A/D converter etc)

TPDF dither can be turned on:

Press 

Select

to switch between Dither On and Dither Off.

Changing input names / source naming

The 2 digital inputs can be renamed to reflect the actual source units

you have connected to the 740C. Press the 

Menu

button to scroll to

either the Digital Input 1 or Digital Input 2 naming menus: 

Press 

Select

to start changing the name of the input. The first editable

character will begin to flash. Use the 

Stop

button to go up through the

alphabet/available characters, and 

Play/Pause

to scroll down. To accept

your character selection, move to the next character by using the

Skip/Scan

buttons: 

To save and exit, press 

Select

. To cancel and exit, press 

Menu

.
