Figure 3.1 DAC-8416 — Components
1. EQ Switch (SW1)
Use SW1 to insert the cable equalizer into the incoming AES/EBU signal. The DAC-8416 can
recover digital audio signals conforming to AES/EBU specifications and transmitted over 75ohm,
coaxial cable, up to 600m (2000ft) long without equalization. For cable lengths in excess of 600
metres, we recommend that the input equalization be activated. Note that switching the EQ in and
out can cause audible artefacts.
• Pressing SW1 enables this feature. The yellow EQ LED is lit.
• While SW1 is activated, pressing it again will disable the EQ and the yellow EQ LED
will go off.
2. DIP Switches
Eight DIP Switches are provided on the card surface to configure the tone generator, remote
control, and analog output levels. Refer to the section “
Configuring the DIP Switches ” on
page 3-3 for details on using the DIP Switches.
3. Input Impedance (H1)
Use H1 to select the input Z value. It is factory set to 75ohm.
