This guide is designed to make installing and using this product as easy as possible. Information in this document has been carefully checked for accuracy at the time of printing; however, Cambridge Audio’s policy is one of continuous improvement, therefore design and specifications are subject to change without prior notice. This document contains proprietary information protected by copyright. [. . . ] If both the optical and co-axial outputs have connections made to them, neither will work. S/P DIF co-axial – to obtain best results, use a high quality 75 ohm digital RCA interconnect cable (not one designed for normal audio use). TOSLINK optical – use a high quality TOSLINK fibre-optic interconnect cable designed specifically for audio use. You cannot connect a Dolby Digital 5. 1 or a DTS signal as they will not be recognised. If you wish to connect a DVD or similar device, please ensure that the sound output of your player is set to twochannel PCM. 15 5 USB in A USB B type socket is fitted to the DacMagic Plus to enable the playback of audio from a personal computer running either Microsoft Windows or Apple Mac OS X operating systems. Note: Always use a certified cable for USB Audio, preferably one that displays an official mark. For USB Audio 2. 0 the cable should be the ‘Hi-Speed USB’ certified. USB cable connections longer than 3m may result in inconsistent audio performance. 6 Ground/Lift switch When Grounded the Dacmagic Plus is connected to the earth connection of the PC directly. When Lifted the ground connection is made via a network designed to break any hum loops that may be caused by the source equipment. We advise using the Grounded setting unless audible hum is experienced. 7 Ext. device Allows connectivity of USB audio enabled Cambridge Audio accessories, such as the BT100 Bluetooth adaptor. 8 DC 12V 1. 5A power adaptor socket Once you have completed all connections, plug the supplied power adaptor into the DacMagic Plus. Important Note: Use the supplied power supply unit ONLY. 16 azur Front panel controls 4 6 1 2 3 5 DacMagic Plus ENGLISH 7 1 Power on/off Source Switches the unit between on and off. 2 Press to select between USB, External (Ext. ) or Digital Inputs 1 and 2. The corresponding LED will light up to show which source has been selected. 3 Digital volume control When headphones are connected, the headphone volume can be adjusted using the volume knob. Note: This is always independent of the level of the balanced or unbalanced audio outputs. If the Dacmagic Plus has been placed in Digital Preamp mode the Volume control also adjusts the output of the Unbalanced and Balanced Audio outputs. Rotating the volume control counter clockwise beyond minimum volume turns on Mute (DacMagic Plus flashes the source LED constantly). Rotating the volume control clockwise until maximum volume is achieved causes the DacMagic Plus to briefly flash the source LED. Further rotations in the same direction in either case do nothing. 17 4 Filter/Phase select Momentarily press to select between three different filter modes: linear phase, minimum phase or steep, see later section for details. The corresponding LED will light up to show which filter has been selected. 5 Phase Press and hold the Filter/Phase select button for approximately two seconds to select normal or inverted phase output. If you suspect that your source material or amplifier, etc. , is inverting the phase of the musical signal, you can use this function to re-invert the audio and regain absolute positive phase. 6 Incoming sample rate In the presence of an incoming digital stream, the relevant LED will light up to indicate the incoming digital sampling frequency (between 44. 1kHz and 192kHz LPCM). For 32kHz material, the DacMagic Plus will still operate but no LED will be lit. 7 Headphone connection Allows for the connection of headphones with a ¼″ jack plug connector. Headphones with an impedance of between 32 and 600 ohms are recommended 18 azur Audio output connections Note: Do not turn on the unit until all connections have been made.

[. . . ] The sampling frequency of the Digital Input will be displayed on the front panel (e. g. Momentarily press the Filter/Phase selector button to cycle between three different filter modes. The DacMagic Plus will output analogue audio from the Unbalanced/Balanced outputs upsampled to 24-bit/384kHz. A ‘raw’ S/P DIF co-axial and TOSLINK optical digital output is also provided. [. . . ]
