SPL Director MK2 Preamplifier

Stereo Sources

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.

The source selection is shown in the dot matrix LED display:

• IN 1 through IN 6 for the analog inputs
• AES, USB, COAX, OPTIC for the digital inputs

For the digital inputs, the detected sample rate is displayed after about two seconds. For example U768 = USB input with 768 kHz sampling rate.

The source selection can also be operated remotely if the rotary switch is set to the “Remote” position.

The Director Mk2 offers:

• Two pairs of balanced inputs with XLR connectors
• Four standard inputs with gold-plated RCA connectors

On the digital side there are four additional inputs.

• PCM audio is received in S/P-DIF format via coaxial Cinch, optical Toslink and balanced XLR (AES).
• Both PCM audio and DSD audio can be converted via USB.

Auto Settings

The DAC automatically picks up the sampling rate and resolution of the digital playback source. No matter if a streamer, computer or CD player is connected. No further settings on the Director Mk2 are necessary.

The detected sampling rate is shown in the dot matrix LED display. For example, U768 is an acronym for the source “USB” with a sampling rate of 768 kHz.

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.
