SPL Director MK2 DA Converter And Preamplifier
The director sets the tone.
The central unit of the HiFi system is the preamplifier. With remote source selection and volume control, retro-look-VU-meter, premium DA-converter and the all superior VOLTAiR technology, the Director Mk2 caters for musical blockbusters.
Volume Remote Control:
The volume can be remote controlled with any infrared remote control, that the Director Mk2 simply learns.
Source of joy:
Up to ten (10 !) stereo sources can be connected to the Director Mk2. Six of them are for analog and four for digital input signals. AES, USB, COAX, OPTI for the digital inputs, where the detected sample rate is displayed after about two seconds. For example U768 = USB input with 768kHz sampling rate.
The Director Mk2 offers two pairs of balanced inputs with XLR connectors and four standard inputs with gold-plated RCA connectors.
DAC768v2 – the SPL reference DAC in the newest revision!
The highly acclaimed AKM AK4493 SEQ VELVETSOUNDTM premium DAC chip is used as the converter chip in the digital/analog converter within the latest version of the SPL DAC “DAC768v2”, which thanks to its architecture reproduces the finest sound details. It impresses with even lower distortion characteristics and a wider dynamic range than its predecessor. It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768 kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256. The DAC768v2 features the newest version of the Spartan FPGA – Spartan 7. In contrast to the smaller SPL DAC “DAC768xs”, it not only offers an AES/EBU digital input, but also the new, optimized SPL SLP120 with VOLTAiR technology.
The DLP120:
The analog output of the DAC chip must be filtered by a low pass filter. Director Mk2 has two of them: One for PCM audio and one for DSD audio, since different roll-off frequencies are required.
And in contrast to all other DACs in the world, the low pass filters here are built using VOLTAiR technology, which provides a plus in dynamics and headroom.
