2. GETTING STARTED
2.1. Unpacking your AD-2 Dual-rate A/D converter
Check that you have the correct power lead with your AD-2 and that they and the
packaging are undamaged. Check that your unit is set for operation at the mains
voltage appropriate for your area. See section 7.7 for more details.
** WARNING ** If the unit has been transported or stored at a low temperature
and is unpacked in a warmer environment there is a danger of
condensation. This could cause the AD-2 to malfunction, so to
avoid problems, allow the unit to warm up to room temperature
for at least 1 hour before use.
Please keep the packaging for re-use.
2.2. Using the AD-2 for the first time
Be ready to check the firmware revision number when the unit is powered on for the first
time. Following switch on, this is briefly displayed as follows:
Prism Sound
Dream AD-2 V1.0x ; The ‘x’ means that this digit may be any number.
If a different version is indicated, contact Prism Sound or your local supplier.
The AD-2 will perform brief initialization, in which all the LEDs are turned on
momentarily (this allows a quick visual check of the LEDs). The unit will settle with the
following text at the start of the first line of the LCD display:
Level : dBFS
On leaving the factory, the settings of the AD-2 will be those of A-D mode Factory
Preset #1, which are as follows:
" A-D mode
" Main output at 96kHz sampling in 2-wire (Split96) format using both XLR
outputs; Main also on the BNC connectors in Split96.
" Aux output on TOSlink optical and RCA Phono outputs, set to 96kHz sampling,
24-bit.
" External Wordclock reference enabled (defaults to internal if none).
" Analogue input amplitude for full digital code (0dBFS) set at +18dBu. This is
consistent with line-up at +4dBu/0VU with 14dB headroom.
If these settings are not suitable, either use the Set-up Wizard or check the table of
presets in sections 2.3 and 2.4 and select one using the method described on page 11.
