Rear panel connections

Unbalanced audio outputs
Balanced audio outputs
Digital inputs 1 and 2
USB Audio In
For connecting to PC/MAC computers.
Note: Class 2 USB Audio only. Windows-based PCs require a Cambridge Audio USB driver to be installed before connection.
Ground/Lift Switch
Ground – This is the default position if no issues are experienced with USB connection. USB host and DacMagic 200M use a common ground for highest link reliability.
Lift – Lifting the USB host ground can be useful if electronic hum is heard through the speakers. The switch should otherwise be left in the Ground position.
Bluetooth Antenna
Used for wireless streaming Bluetooth audio directly from most phones, tablets and laptops. See Bluetooth section for details.

Audio output connections

Last updated: January 26, 2021 10:54. Revision #1035 dacmagic 200m / audio output connections
Note: Do not turn on the unit until all connections have been made.
You can use either the unbalanced (RCA/Phono) or balanced (XLR) outputs of the DacMagic.

Unbalanced connections

Balanced connections

The XLR output is preferable for long connections if your amplifier features balanced XLR inputs. It can better reject noise and interference in the cable. It is possible to use the RCA phono connections and the XLR balanced connections at the same time, e.g. for connecting to different amplifiers or multi-room operations.

Digital audio input connections

Last updated: January 22, 2021 12:48. Revision #1036 dacmagic 200m / digital audio input connections
Note: Do not turn on the unit until all connections have been made.

TOSLINK connection

Co-axial connection

Connect your digital source to Digital Input 1 or 2. Either S/P DIF co-axial or TOSLINK optical types can be used. Optical is best to avoid ground loop noise, but some optical cables may not work correctly at 192kHz.
Important Note: Only connect one co-axial OR optical cable to each digital input. The unit will not operate if both connections are made (even if only one is active).

USB connections

Last updated: March 2, 2021 10:28. Revision #1057 dacmagic 200m / usb connections
Note: Do not turn on the unit until all connections have been made.

USB Connection

USB Connection

Class 2 USB Audio only. Windows based PCs require a Cambridge Audio USB driver to be installed before connection.
Note: Use a certified high-speed USB 2.0 ‘A–B’ cable

Master Quality Authenticated (MQA)

Last updated: February 23, 2021 10:44. Revision #1038 dacmagic 200m / master quality authenticated mqa
MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download.

Visit mqa.co.uk for more information.

DacMagic 200M includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.

The MQA LED glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.

Cambridge Audio

The MQA LED glows magenta to indicate that the unit is rendering an MQA stream or file. This delivers the final unfold of the MQA file.

Bluetooth

Last updated: March 9, 2021 04:54. Revision #1225 dacmagic 200m / bluetooth

Selecting this allows the DacMagic 200M to receive wireless Bluetooth audio from most phones, tablets and laptops.

Pairing
To pair a new BT device with the DacMagic 200M you need to:

Make sure any previously paired BT device is turned OFF (this product will auto-connect to the last paired device)
Turn on Dac Magic 200M and select BT as a source
Activate BT on the source device
Scan for available devices on the source device and select ‘DacMagic200M’

Unpairing
To unpair a device, you can select ‘Unpair’ in the phone’s device list, or perform a factory reset on the DacMagic 200M, as this will delete all previously paired devices.

Note: Your device can only be paired and connected to the DacMagic 200M while the Bluetooth source is selected.

Paired LED status
Once your device is paired, below are the LED status of the type of codec that is being received.
SBC Codec is represented with a solid light.
aptX Codec is represented with a 2 seconds solid light followed by a very short light off interval.

Auto Power Down (APD)

Last updated: January 19, 2021 10:23. Revision #1040 dacmagic 200m / auto power down apd

The product will automatically switch to standby mode after inactivity of 20 minutes. To enable or disable this function, see below instruction:

Important note: Make sure that the DacMagic 200M is in the Standby state, before performing any APD functions.
Auto Power Down

APD OFF – Press and hold down the Volume knob for 5 seconds, and wait for the Input LEDs to blink 2 times.
APD ON – Press and hold down the Volume knob for 10 seconds, and wait for the Input LEDs to blink 5 times.

Advanced settings

Last updated: February 8, 2021 01:05. Revision #1041 dacmagic 200m / advanced settings

Important note: Make sure that the DacMagic 200M is in the Standby state, before changing any settings.

Factory reset: All user-stored settings (input, volume and output mode) will be erased and replaced by the unit’s default settings.

Product Installation

Short press both Source and Filter buttons. All LEDs will light in sequence, one by one.

Product Installation

Fixed/variable out mode is toggled by short pressing the Volume knob and the Filter button at the same time:
RCA/XLR output set to fixed mode – MQA/DSD light up for 5s.
RCA/XLR output set to variable mode – 176.4/768 LED’s light up for 5s.
Note: Headphone output is always variable.

Check MCU SOFTWARE version: Double press Source button first and then double press the Filter button.
For example, if the MCU version is V2.1, then the front panel LED should be showing:
MQA LED – Blink 2 times
44.1k LED – Blink 1 time

Ensure the mains plug is fully inserted into the wall socket and is switched on.

There is no sound
Ensure that the amplifier is set correctly. Check that the interconnects are inserted correctly. Check that the correct digital input is selected (Incoming Sample Rate LED should be on).

A low hum or buzzing sound can be heard
Power cords or lighting placed near this product. Analogue inputs are not securely connected.
