IOM-HORUS DA8/DA8P
The
DA8
(up to 192kHz) and the
DA8P
(up to DSD) have been shown in testing to be consistently the quietest
multichannel D/A conversion modules available anywhere.

y once, at product installation, and only if the desired Operating
Line Level differs from the default ex-factory settings of +18 dBu for 0 dBFS.
Procedure for Hardware alignment:
1. Shut down your Horus and make sure that the Horus back panel Power is also switched OFF.
2. Unscrew all DA8 modules that need adjustment.
3. Pull gently out (5-7 cm is enough) to access the DIP Switches. There is one block of 4 dip switches per
channel. Channel 1 is labeled S1, channel 8 is labeled S8.

• Dynamic range of 127dB (typ.)
• Easy to set dip switches for internation leal opera
