When clocked externally, the Aurora
(n)
uses Lynx’s proprietary SynchroLock II clocking feature to reduce
jitter and clocking anomalies. SynchroLock II takes only a few seconds to achieve full lock. While it is
locking the SynchroLock indicator will show “Unlocked”, and will show “Locked” when full lock is
achieved. SynchroLock will re-engage whenever the Sample Rate changes. SynchroLock can be disabled, by
highlighting the SynchroLock indicator and pressing the Select button or pressing in the rotary encoder. In
general, it is recommended to keep SynchroLock engaged when using an external clock source.
6.2.2 Line Trim
Aurora
(n)
can operate at a nominal trim level of +4dBu (Pro), or -10dBV (consumer). Trims can be switched
between these values for the analog inputs and outputs in banks of 4 channels. The Aurora
(n)
has 16dB of
headroom, so in the +4 position it operates at +20dBu = 0dBFS, and at -10dBV it operates at +6dBV =
0dBFS. In general, Pro Audio equipment (mixing boards, effects processors, powered monitors, etc.) should
have +4dBu selected, and consumer gear (cassette decks, stereo receivers, surround processors) should be set
to -10dBV. When in doubt, check the documentation for connected equipment to select the appropriate trim
value
6.2.3 Preamp
The “Preamp” page can have two different display formats: 8-channel and 4-channel mode, depending on the
configuration of the Aurora
(n)
. Use the Up and Down arrow keys to change the currently selected channel.
Change the gain for the selected preamp with the Rotary Encoder. Please note that pressing the Rotary
Encoder does nothing on this page to prevent inadvertent gain changes. Use the Function button to change
between the six controls, and the Select button to change the state of the currently selected control.
The left half of the preamp page shows a summary of all of the preamp channels settings. Let’s take a look at
one of the preamp channels in detail.
Pad indicator. On when 13.6dB pad is enabled.
48V indicator. On when 48V phantom power is applied to this input.
Gain display and relative position indicator. Will show “Line” when input is
set to Line.
Phase indicator. On when phase reversal is enabled.
Hi-pass filter indicator. On when 80Hz, 12 dB / octave hi-pass filter is
enabled.
Channel number.
Level meter with peak hold and overload.
