AKD39 Ultra DAC

NEW! ESS 9039PRO-based DAC in stereo, or multi-channel... fully assembled and tested, ready to listen!

-USB Audio --  HiRes 2CH 768KHz PCM, DSD1024 with ASIO drivers (Win10+, Linux)

-Spdif Coax - up to 192KHz with high performance transformer isolation ('Scientific Conversion" type). Options for AES/EBU or Optical inputs

-2CH Stereo and Multichannel versions. Controls up to two DACs automatically for up to 16 channels. 

-Full MQA decoding, unfolding and rendering (2 Ch Stereo) with compatible software.

-Current mode outputs with True-Balanced I-V conversion.

-Ultra-high performance IC OpAmp 1612 I-V for Output Stages. 

-Precision nulled output offsets

-Ultra-low distortion line outputs, THD+N: -120dB typ.

-Parallel combined channel output drive in 2CH Stereo mode for increased dynamic range - 137dB DNR typ.

-Direct-coupled Pro-Audio outputs: Balanced XLR (10Vrms) and SE RCA (1-5Vrms). All fully balanced processing, even for SE outputs. Strong outputs for direct drive option to most Amps, no pre-amps needed.

-Optimized direct connections. No jumpers, switches or links in signal paths.

-4 layer composite board optimized for high speed mixed signals.

-Wiring mostly embedded on board 

-High quality audio grade components throughout. Top-of-the-line precision "naked" bulk metal foil audio resistors x32 (TexasComp) and film capacitors for critical sections

-On-board low phase noise femto clocks (NDK SDA). External Master Clock input option.

-Asynchronous or Synchronous clocking schemes

-ultra-low noise regulators for Vref power of DAC.  All separate power supply points with individual regulators

-High performance DAC Controller. Galvanically isolated from DAC for minimal interference. Control and configuration of DAC module via on-board switches.

-Lossless Digital Volume Control, Direct or PreAmp mode

-Trigger Output for power amps or AV systems

-mains power SMPS included

-mostly modular design with some options to upgrade, mod or tweak as desired

-Dimensions: (2ch version~35cmx22cm), (8/16ch version ~35cmx35cm)

-Back panel included for simplified installation into suitable casing (casing not supplied)

-Supplied as shown. Options are extra at cost.
