7.1. Input selection
The
EVO PHONODAC TWO
is provided with three inputs: one is the USB port (Fig. 2, 8), th
second one is the analog input (Fig. 2, 10) and the third one is the S/PDIF input (Fig. 2, 6),
which may not be available is an external clock generator is connected to the
EVO
PHONODAC TWO
. They are selected in a sequential fashion using the input/menu button
on the remote control.
NOTE: that when the external clock is used, the S/PDIF input is not included in the
inputs list for selection.
7.2. HID with the USB input
The
EVO PHONODAC TWO
allows the user to control the player on the computer when the
USB input is selected. The following commands are available:
•
Play/Pause (“OK” button);
•
Stop ( “OK” button, long press);
•
Previous track ( “arrow left” button);
•
Next track ( “arrow right” button).
To use the HID feature, it is necessary to use a compliant player.
7.3. Analog input gain and impedance
The
EVO PHONODAC TWO
is provided with an analog input with settable gain between 0dB
and 62dB and impedance between 10 Ohms and 50k Ohms. This makes the
EVO
PHONODAC TWO
suitable to accept signals from both high-level sources (like CD players,
tuners, guitar head units, mixers…) and low-level sources (like phono cartridges, tape
heads…). Input level can be up to 2.5Vrms at 0dB gain.
While the input gain is set by menu, input impedance is set by a pot on the back panel.
Some relevant values are indicated on the panel’s silkscreen, but any value between 10
Ohms and 50k Ohms can be set.
7.4. Equalization
The
EVO PHONODAC TWO
is provided with DSP capabilities which allow for equalizing the
signal right after the analog-to-digital conversion. The
EVO PHONODAC TWO
is provided
with a wealth of equalization curves to fit every record standard, from old 78rms to modern
33rpm, plus some reel tape eq curves for reel-to-reel tape recorders fans who want to
