Mytek Digital Stereo 96 DAC (VER.8/sep 2010) - Manual (Page 7)

Typical Setup
Balanced Output
Stereo96 DAC is equipped with 2 XLR analog outputs. For best signal to
noise performance it is recommended that the signal destination has a
typical kOhm impedance (1-20kOhm) input with standard +4dB line
level balanced signal. Alternatively a more sensitive unbalanced signal
destination can be used as described in subsequent paragraph.
In typical setup the DAC is running on its internal clock in Superlock
(tm) mode. In this mode Mytek DAC serves as a very stable low jitter
clock source which enables TOTAL jitter immunity which means that
any jitter at the DAC digital in is completely removed. In this mode all
digital input formats sound exactly the same with no jitter distortion due
to jittery source, jittery CD or long input cables. Because of careful
design this clock is as good or better than dedicated studio clock
generators. Additionally in Superlock(tm) mode signal of any format
(any FS, 16, 20 or 24 bit) is upsampled to 192k/24 bit resulting in overall
more realistic and accurate sound. When synced to “digital input” the
DAC works as a typical CD Player DAC where jitter is attenuated but its
effects can be heard. This second mode is provided for comparison
purposes- it allows mastering engineer to assess how the program will
sound when played by consumers on their typical DACs.
Setup for typical balanced operation includes following steps:
1. Setup internal jumpers to desired mode of knob operation. Setup all
other connections. Set sync to Superlock(tm). Alternatively for testing
purposed set sync to input.
2. Select desired signal source. Solid selector led at given input means
proper input lock. If input led is flashing there is either no signal or a
problem with locking to it. The DAC will automatically sync to any
frequency btwn 32-96k (external input sync) or 32-192k (Superlock(tm))
3. Play the program- you should be seeing level on the meters as well as
hearing the signal at output XLRs and headphones. Turn up the volume
knob if necessary. If levels at your power amp are inadequate for the
volume knob position- change the out alignment using trimpots.
