With the settings specified in table [
C
] you get a preamp output voltage of 500 mV.
Cartridge manufacturer often offer the output voltage of their pickups as follows:
Output voltage = 0,4mV at 3,54cm/s
The normalized output voltage usually refers to a reference of 5.6 cm / s
.
In our case,
therefore, results in the output voltage to:

Thus, there is an output voltage of about 0.63 mV, ie. you should set a gain of about
58.5 dB.

4.7. DAC Modul
Four digital source devices can be connected to the DAC module. Use the arrow
keys (
7
) and (
8
) on the front panel of the
Epilog
to choose the input. Following
inputs are available:
2x Coax (Cinch) SPDIF
1x Toslink
1x USB
If this is four digital inputs are not enough, further DAC Modules can be installed.
Five DAC modules are possible so that you get 20 digital inputs!
The DAC module translates the digital music information into analog audio signals
that can then be processed in the
Epilog
. The maximum resolution of the DAC
module is 24 bits and 192 kHz (compared to CD players have a resolution of 16 bits
and 44.1 kHz). The maximum resolution of the USB input is 24 bits at 96 kHz. The
DAC module automatically adjusts to the required resolution.
All inputs are galvanically isolated, i.e. the DAC is connected to an input transformer
or optically coupled to the source equipment. In this way, any hum are (keyword
ground loop) effectively prevented.
