DacMagic
Introduction
Thank you for purchasing this DacMagic Upsampling Digital to Analog Converter. We are confident
that you will enjoy many years of listening pleasure from it.
The DacMagic features ATFTM (Adaptive Time Filtering), an up-sampling process developed in
conjunction with Anagram Technologies of Switzerland to intelligently interpolate incoming audio data
(of between 16-24 bits, 32-96kHz) to 24bit/192kHz through the use of a 32bit Texas Instruments DSP
(Digital Signal Processor). The ATF system applies sophisticated polynomial curve-fitting interpolation
to create the extra data points and incorporates a time domain model which adaptively generates the
new data in the temporal domain, dramatically reducing digital jitter, even that present in the input audio.
As with our high-end CD players, our proprietary Dual Differential Virtual Earth Balanced filter topology
is used, configured as a low-order two pole linear-phase Bessel filter to take advantage of the high
sampling rate achieved. Two very high quality Wolfson WM8740 24bit DAC ICs are used in dual
differential mode. Since each channel has its own DAC to process information, completely separate
and symmetrical analog filter circuitry can be implemented. These allow both left- and right-channel
circuitry to operate identically, ensuring the DacMagic delivers fantastic sound-staging and stereo-
imaging properties.
Two digital inputs are fitted (both featuring S/P DIF and TOSLINK) and allow a wide range of digital
sources to be connected. In addition, a USB input enables the DacMagic to be connected to a PC
and act as a very high quality DAC/Soundcard, offering genuine HiFi-quality playback from your
desktop, media PC, etc. A digital output is fitted which passes through the selected digital source for
recording purposes (no up-sampling performed).
Your DacMagic can only be as good as the system it is connected to. Please do not compromise on
your amplifier, speakers or cabling. Naturally, we particularly recommend amplification from the
Cambridge Audio range. Your dealer can also supply excellent quality Cambridge Audio interconnects
to ensure your system realises its full potential.
Thank you for taking the time to read this manual; we recommend you keep it for future reference.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
1) This device may not cause harmful interference;
Manured in an ISO9001 approved facility
2
2) This device must accept any interference, including interference that may cause undesired operation.
1 Unbalanced Audio Outputs
Single-ended conventional stereo outputs for connection to the line-level phono/RCA inputs of an
amplifier.
2
Balanced Audio Outputs
The DacMagic also features true balanced (XLR) outputs. This is a higher quality output that can
reject noise and interference with equipment with balanced inputs. These balanced outputs are
ideally suited for connection to the Cambridge Audio 840A or 840E amplifiers. XLR connectors should
be wired as follows:
Pin 1 – Ground; Pin 2 – Hot (in-phase); Pin 3 – Cold (phase-inverted).
3
Digital Outputs
The digital outputs allow a digital recording device to be connected. These outputs loop or pass-
through unprocessed digital audio from the selected digital input. Two types are available (both the
co-axial and the optical are active concurrently and can be used to connect and run equipment at the
same time):
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).

DacMagic
TOSLINK optical – use a high quality TOSLINK fibre-optic interconnect cable designed specifically for
audio use. To achieve the best results we always recommend using high quality Cambridge Audio
leads, which are guaranteed for life.
Note: These outputs are pass-through only; there is no upsampling or any other modification done to
the LPCM input signal.

5
Digital Inputs 1 and 2
The DacMagic is fitted with two sets of digital inputs which enable the connection of source
components. Each input has both S/P DIF and TOSLINK types fitted.
Only one of the two types for each input should be connected at any one time. If both the optical and
co-axial outputs have connections made to them (even if only one is attempting to function), 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.
Note: This unit only accepts two-channel LPCM digital audio (e.g. Dolby Digital 2.0). 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 two-channel PCM.

Use either the unbalanced (RCA/Phono) or balanced (XLR) outputs of the DacMagic. The XLR output
is slightly better in quality as it can reject interference and noise in the cable connection and is the
preferred option if your amplifier features balanced XLR inputs. 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.

Connect a USB ‘B–A’ type lead (as illustrated at left) from the DacMagic’s USB input to one of the USB
ports on the PC. This is the normal type of USB lead with an oblong plug at one end and a square plug
at the other. Switch on the DacMagic using the front panel On/Off switch and make sure that the
USB input is selected (USB LED lit). The Windows “Found New Hardware” dialogue bubble should
now appear at the bottom right-hand side of the Windows desktop. The description of the DacMagic
will be displayed as “USB audio device”. Installation should be automatic and no driver disc is
required. After a few seconds the message “Your new hardware is installed and ready to use” should
appear to confirm that installation has been successful.
Important Note: The PC’s previous audio output device should now be temporarily disabled and the
DacMagic becomes the default audio playback device for the PC. This can be confirmed in the
Control Panel’s Sounds, Speech and Audio Devices properties window under the Volume tab.
The DacMagic is described as a “C-Media USB Headphone Set” as we use a C-Media USB interface
IC running a headphone (i.e. two-channel) profile.
If you wish to disconnect your DacMagic and return to using your previous soundcard, etc., simply
disconnect it or switch off the power on the front panel.
If the PC fails to disable the DacMagic and automatically re-enable your default soundcard, you can
manually disable the DacMagic in the hardware device manager. To do this, navigate to the Device
Manager (click Start — Control Panel — (Vista: Performance and Maintenance —) System — Hardware
— Device Manager in Windows XP). Scroll down the device manager window and expand the heading
Sound, Video and Game Controllers to display a list of the connected devices. The DacMagic will be
listed as “USB Audio Device”. Click on this description to highlight in blue and then click on the Disable
icon ( ) at the top of the window. A warning message will appear: “Disabling this device will cause
it to stop functioning. Do you really want to disable it?” Click Yes to disable the DacMagic. The previous
audio playback device will now be re-instated by Windows.
Note: As Windows operating systems evolve, the path sequence to the device manager may change.
However, the DacMagic will always appear as a “USB Audio Device” in the Sound, Video and Game
Controllers window.
Note: It is also possible to disable the DacMagic in the device manager by right-clicking on the
highlighted “USB Audio device” and then clicking Disable from the sub-menu window.

Switch on the external source input, e.g. CD player, DVD player, etc.
The sampling frequency of the Digital Input will be displayed on the front
panel (e.g. for a CD player – 44.1kHz). Momentarily press the Filter/Phase
selector button to cycle between three different filter modes.
Start playback of the source equipment. The DacMagic will output analogue
audio from the Unbalanced/Balanced outputs upsampled to 192kHz 24bit.
A ‘raw’ S/P DIF co-axial and TOSLINK optical digital output is also provided.
These outputs can be used to connect a compatible digital recorder, e.g.
CD-R/MD, etc. The DacMagic is compatible with Digital Stereo LPCM of a
sampling frequency between 32-96kHz.
Note: Being a stereo device, this unit does not decode 5.1 Dolby Digital or
DTS Bitstreams from a DVD player, etc. When receiving a multi-channel digital
input, the analogue audio outputs are muted. However, a 5.1 DD or DTS
Bitstream will pass-through to the digital outputs.

Filters
The DacMagic DSP has three different Filter functions: Linear Phase, Minimum Phase and Steep. All
three filters are highly sophisticated audiophile topologies, optimised specifically for audio playback.
In our opinion, these filters offer excellent sound quality but differ subtly in optimisation, hence we’ve
made all three available to you.
Note: For clarity, all diagrams show the theoretical response of the DSP itself, excluding any analog
filtering at the DAC output or the anti-aliasing filter applied during recording and/or mastering of the
digital source.

The Linear Phase filter is a highly regarded audio filter offering low ripple in both the pass and stop
bands, and what is known as constant group delay. Constant group delay means that audio signals
of all frequencies are always delayed by the same amount when passing through the filter. All audio
is therefore fully time-coherent at the output.
The trade-off with this type of filter is that due to internal feed-forward in the DSP, its impulse response
will exhibit some pre-ringing. In other words, when excited with a theoretical impulse, the output has
both a small amount of pre- and post-spike amplitude ringing (albeit well damped).

The Minimum Phase filter is another highly regarded audio filter that offers even lower ripple in the
pass and stop bands. Unlike the Linear Phase filter, group delay is not constant so some time-
coherence is lost; however, phase shift is low and the particular benefit with this filter is that the
impulse response exhibits no pre-ringing.

Our Steep filter is a linear phase filter that has been optimised for stop band attenuation of close-in
aliasing images. Here we have traded a little attenuation of the very highest frequency response (-2dB
at 20kHz) and a little more pre- and post-ringing for a very steep attenuation just outside the pass
band. The Steep filter is able to attenuate aliasing at 22kHz by some 80dB.
