CD player setup

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.
