Frequently Asked Questions - AES DigiSwitch 3X1 Henry Engineering
How do I select an input manually?
Press the corresponding front panel button for input 1, 2, or 3. The active input will be indicated by a green LED.
What is the automatic switching mode?
The DigiSwitch 3X1 automatically selects the first active input with a valid AES/EBU signal. Inputs are prioritized from 1 to 3. If the current input drops out, it switches to the next available.
Can I control the switcher remotely?
Yes, via the DB-9 remote control port. You can connect external switches or a control system for remote input selection.
What power supply does it use?
It uses an external 12V DC power adapter (center positive, 2.1mm barrel jack). The adapter is included with the unit.
Does it support sample rates above 96 kHz?
Yes, the AES DigiSwitch 3X1 supports sample rates up to 192 kHz and bit depths up to 24-bit.
Why is the output silent?
Check that at least one input has a valid AES/EBU signal (LED lit). Verify cables and that the selected input is active. If using automatic mode, ensure input priority is set correctly.
Can I use unbalanced AES/EBU signals?
No, the DigiSwitch 3X1 is designed for balanced AES/EBU signals on XLR connectors. Do not attempt to connect unbalanced signals without proper conversion.
How do I mount the unit in a rack?
The unit is 1U high and fits a standard 19-inch rack. Use four screws (not included) to secure the front panel to the rack rails.
Is there a warranty?
Henry Engineering provides a limited one-year warranty against defects in materials and workmanship. Refer to the included warranty card for details.
Can I switch between inputs without interrupting audio?
Switching is instantaneous, but may cause a short glitch if the new input is not synchronized. For seamless transitions, ensure all inputs are synchronized to the same clock.
