Instantly transform your favourite gadgets into a true hi-fi source!
The multi award-winning DacMagic is the world’s most affordable and effective way to upgrade any PC, Mac, network music player, digital iPod dock, games console or any device with a Digital Audio out to truly high end sound quality.
Storing music digitally has enormous advantages in terms of capacity and instant access, but also requires the signal to be converted into the analogue domain before it can be amplified and delivered to your speakers. DacMagic adds value by directly drawing a digital audio signal from any supported device and employing a vastly superior analogue conversion process. DacMagic instantly adds clarity, vibrancy and dynamism to all digital music and with its ATF upsampling process, noticeably improves heavily compressed music.
With a variety of simple connections including S/PDIF, Toslink and USB inputs, DacMagic can be set-up in seconds. Hearing is believing!

Works with:
Any Mac or PC
Soundbridge Sonos Squeezebox Apple TV Airport Express
Games console
LCD or Plasma TV (Optical out)
Blu-ray/CD/DVD-A Player
Digital iPod dock

ATF™ upsampling explained...

Adapted Time Filtering (ATF) asynchronous upsampling technology might sound complicated but the benefits are instantly audible. Essentially it converts 16-24 bit audio to 24 bit/192kHz so you hear way more from compressed music. Meanwhile a 32-bit Digital Signal Processor (DSP) eradicates jitter – an insidious side effect of playing back music from hard-disk devices like PCs and laptops.
So, however your digital music collection is stored, the difference in audible quality is incredible!

DacMagic Digital to Analogue Converter features

Adaptive Time Filtering (ATF™) asynchronous upsampling technology converts 16-24 bit audio (at any standard sampling frequency between 32-96kHz) to 24 bit/192kHz

32 bit Texas Instruments Digital Signal Processor (DSP)

Dual Differential Virtual Earth balanced filter topology – low order two pole linear-phased Bessel filter takes advantage of high sampling rate achieved

Twin WM8740 high quality DACs in dual differential mode for excellent stereo imaging

Incoming sampling rate indicator 32/44.1/48/88.2/96kHz

Choice of filters – linear phase, minimum phase and steep filter can all be selected to suit an individual’s listening preferences

Phase select to invert or reinvert input, correcting possible recording problems

Two inputs with both SPDIF & Toslink sockets allow wide range of digital sources to be connected

USB input connects direct to PC without drivers to act as very high quality DAC/soundcard providing genuine hi-fi quality playback from desktop or media PC

Singled ended phono and XLR balanced audio outputs

Digital output (SPDIF and Toslink concurrently) passes through selected source for recording purposes

Substantial aluminium front panel plus an entirely new ultra rigid, acoustically dampened chassis

Can be used horizontally (using four rubber feet) or vertically (rubber foot)

Available in silver or black
