The director sets the tone.
The central unit of the HiFi system is the preamplifier. With remote source selection and volume control, tape monitor path, retro-look-VU-meters, premium DA-converter and the all superior VOLTAiR technology, the Director Mk2 caters for musical blockbusters.
Milled from solid
The massive 45mm volume control knob milled from aluminum is a haptic highlight. Its mass together with the motorized Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further.
The red marker LED ensures good visibility of the volume parameter even in darkened environments.
Remote control
The volume control can be remotely controlled with any infrared remote control.
The Director Mk2 learns to communicate with it with the simple push of a button.
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.
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, where 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 and 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.
Well informed
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.
DAC768v2 – the SPL reference DAC in the newest revision!
The SLP120 (Super Low-Pass)
The analog output of the DAC chip must be filtered by a low pass filter. 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 and sound. The filter specially optimized for the new SPL DAC768v2 is called SLP120 (Super Low-Pass).
The DAC768v2 inside the Director Mk2 is equipped with the SLP120 – an analog “Super Low-Pass” filter with VOLTAiR technology.
DAC768v2 – what’s new:
1. AK 4493 SEQ
The DAC768v2 is equipped with the latest generation of the premium DAC chip – the AK 4493 SEQ – from Asahi Kasei (previously AK 4490).
The AK 4493 SEQ impresses with even lower distortion characteristics and a wider dynamic range than its predecessor.
2. Spartan 7
The DAC768v2 features the newest version of the Spartan FPGA – Spartan 7 (previously Spartan 6).
3. The newest generation of the SPL low-pass filter “SLP120”
The DAC768v2 comes with a completely new tuned low-pass filter, which perfectly matches the sonic strengths of the new converter chip. It ofers an even better representation of the stereo image as well as a three-dimensionality we never experienced from any other DAC before.
The new DAC revision can be recognized by the “DAC768v2” label on the serial number sticker.
The design of the DAC768v2 is unfortunately not compatible with devices that were built with DAC768.
In addition to the original DAC chip (previously AK4490, now AK4493), other components in the digital environment that are no longer available, such as the previously used version of the Spartan-6 FPGA (now Spartan-7), had to be updated. As the technical characteristics of these components are different from those of their predecessors, further technical adjustments had to be made to the device in order to achieve the best possible sonic performance of which SPL is known for. The analog low-pass filter with 120V technology is also different in the devices with DAC768v2.
It is therefore not possible to simply replace the DAC768 module with the DAC768v2 module.
All variable – or Slave Thru?
The Director Mk2 provides two stereo output pairs for connecting power amplifiers or active loudspeakers.
One pair of outputs with XLR, the other with RCA outputs. Both have the same output signal, which is controlled by the big volume control. Thus, a pair of speakers can be fed via one stereo output and a subwoofer via the second stereo output. The playback volume for both stereo outputs is adjusted together via the volume control on the Director Mk2.
With a DIP switch on the back of the device, the volume control for the RCA and XLR outputs can separately be switched out of the signal path – this makes the respective output a “Slave Thru” output to e.g. connect a headphone amplifier with its own volume control. The volume control of the Director Mk2 no longer affects the playback volume of the connected headphone amplifier when a stereo output’s Slave Thru mode is active.
Home Theater Bypass
Since the hardware revision 2.2, the Director Mk2 features a Home Theater Bypass function. This allows the Director Mk2 to be used in combination with a multi-channel home theater system. The L and R channels of the home theater system can be simply connected to Input 6 of Director Mk2. When the Home Theater Bypass is active (DIP 4), Input 6 is no longer affected by the volume control of the Director Mk2.
Everything under control – AMP CTL
The standby mode of devices with 12V trigger input, can be switched on and off via AMP CTL, together with the Director Mk2. This allows, for example, the SPL Performer s800, Performer m1000 or Performer s1200 power amplifiers to be ideally integrated into the set-up.
Sounds good
With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.
The VOLTAiR Technology
The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.
The highest possible audio quality requires the highest possible audio operating voltage.
The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.
The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.
By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.
The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
Comparison
Most audio devices work with an internal operating voltage of +/-15 volts and can thus process a maximum input level of +21.5 dBu. If a DAC, for example, has an output level of +22 dBu at 0 dBFS, level peaks of the music material would already cause overloads in the input stage of the device. All components in the audio device often operate at their limits. The result is an unsteady sound that causes stress and faster ear fatigue.
SPL devices with VOLTAiR technology can handle input levels of +32.5 dBu thanks to the higher internal operating voltage of +/- 60 volts – thus offering 12 dB more headroom. All components consequently operate continuously in the optimum operating range. The result is a very pleasant, natural and relaxed sound experience. So you can enjoy your music in every detail.
These diagrams clearly show the superiority of the VOLTAiR technology in comparison to other circuits with lower, common operating voltages.
