Evo 150 rear panel connections

evo 150 rear panel

1. AC Power socket

2. Speaker terminals

B Speaker
For connecting a second pair of loudspeakers.

3. Evo CD
A dedicated connection from an Evo CD player.

4. Audio return channel (ARC)
A connection from a TV that supports ARC function.

5. USB Audio In
For connecting to PC/Mac computers.

Note: For Class 2 USB audio, Windows-based PCs require a Cambridge Audio USB driver to be installed before connection.

Ground Switch

Note: The ground switch position should be set to 1 as default. Use another position if a humming noise occurs.

Position 1 – Normal/default position. The main unit audio ground is lifted from chassis earth.

Position 2 – USB Audio ground is lifted from the main unit audio ground, which is also lifted from chassis earth. This may be useful to reduce hum and noise that can occur with some USB Audio setups.

Position 3 – Main unit audio ground is connected directly to chassis ground and USB Audio ground. For some setups, this can reduce hum or noise when certain TVs, Turntables, and other equipment are connected to the Evo unit.

6. USB Media
For connecting local media storage. Note that the USB ports are not intended for connection to Apple mobile devices; no functionality, charging or otherwise is supported.

7. Ethernet
Use a wired connection for seamless playback of high-resolution 352.8kHz, 384kHz, and DSD 256.

8. Trigger Out
Use a link wire between the Evo 150 and a product that has a trigger input. This will synchronise the power state of both products when powering the Evo 150 on/standby.

9. Trigger In/IR In

Trigger In – Use a link wire between a product that has a trigger output and the Evo 150. This will synchronise the power state of the Evo 150 with the controlling unit

IR In – Receives modulated IR commands from an IR repeater or custom install systems.

10. RS232C
Custom install control
– a full protocol is available for the Evo 150 on our website.

11. Digital Inputs (Coax and Optical)

Note: If a digital input is connected to a TV you can enable TV mode in the input settings of the StreamMagic app. This mode minimises lip-sync delays on the audio path by bypassing MQA decoding and also reduces the chance of dropouts and glitches from some TVs.

12. Analogue Inputs (AUX/XLR)

13. MM Phono input
For connecting a turntable that uses a moving magnet cartridge.

If your turntable has a separate grounding lead, then connect here.

14. Sub-Out

15. Pre-Out
