3.3.1.1 USB port
The USB port on the CONTROL board is dedicated to upgrading the firmware of the M1.1 unit. Do not use it for any other purposes.
For more information on unit firmware update, please refer to the relevant section in this manual.
3.3.1.2 Ethernet port
The Ethernet port allows the control of the M1.1 amplifier settings through a standard Ethernet network. Connect the M1.1
Ethernet port to an Ethernet Router or Switch using an Ethernet RJ45 Category 5 or better. Using the CH Android App, the M1.1
settings can be accessed and adjusted on the fly via a tablet.
3.3.2 ANALOG IN board
The ANALOG IN board features a user selectable analog input on three different connectors: balanced XLR, single-ended RCA and
single-ended BNC. The analog stage design is fully discrete and balanced. Both the RCA and BNC inputs can be configured for high-
impedance or 300 Ohms load. The latter helps to reduce signal reflections as well as to improve external noise immunity, therefore
improving the overall signal transmission. In addition to the inputs, the ANALOG IN board includes an XLR output creating an input
signal pass-through. This output can be used to daisy-chain multiple M1s (and A1s) in multi-amplification systems for ultimate
performances. Balanced connections are recommended for optimal performance. The Following drawing shows the layout of the
connectors on the ANALOG IN board.
