If you need top audio playback quality from your digital sources, look no further than the black Diamond from SPL, a premium DAC and preamplifier designed to handle digital audio from multiple types of sources and reproduce them with impeccable accuracy. With support for up to 32-bit / 782 kHz digital PCM and DSD250 audio decoding through the AKM AK4490 DAC and analog DLP120 dual low-pass filter chips, the Diamond can deliver the full sonic character of any digital source while also making sure no beat is out of step thanks to the ability to select between the clock from the digital signal or a dedicated BNC word clock input.

Flexible digital input options include AES XLR 3-pin, two S/PDIF RCA coaxial jacks, two optical TOSLINK S/PDIF jacks, and a USB-B port, which provides the highest sample rates, while balanced XLR and unbalanced RCA outputs are provided stereo analog connection to your speakers or mixer. The innovative onboard VOLTAiR technology and shielded toroidal transformer delivers superior rail voltage for the internal circuitry, ensuring that the Diamond provides the highest quality audio experience possible by vastly improving dynamic range, distortion, SNR, and maximum gain levels.

The volume is adjusted with a solid, milled aluminum, rotary knob. The Alps RK27 Big Blue potentiometer gives a pleasant spoon in the honey rotary feel.

Up to six digital stereo sources can be connected to the Diamond, making this DAC/preamp an ideal heart for any digital audio system. Diamond offers both a stereo USB and AES input as well as two optical and coaxial stereo inputs. The selected input is also shown in the dot matrix LED display.

Via USB, both PCM audio and DSD audio can be converted. PCM audio is received in S/PDIF format, both coaxial (RCA), optical (TOSLINK F06) and balanced (AES/EBU).

Diamond can not only synchronize to the clock integrated in the digitally fed source signal. As a specialty for digital players, Diamond offers a word clock input. The source of the clock signal can be selected via the clock switch.

The DAC automatically picks up the sampling rate and resolution of the digital playback source, regardless of whether a streamer, computer, CD player, or an external word clock is connected. The detected sampling rate and the selected clock source are shown in the dot matrix LED display. For example, U768 is an acronym for a clock signal in the USB stream with a sampling rate of 768 kHz.

Diamond provides two stereo output pairs for connecting power amplifiers or active loudspeakers. One pair of outputs utilizes XLR 3-pin connectors while the other uses RCA outputs. Both have the same output signal, which is controlled by the volume control on the front panel.

The volume control for the RCA outputs can be switched out of the signal path via DIP switch on the back of the device. For example, a headphone amplifier with its own volume control can be connected to one of the outputs.

The highly acclaimed AKM AK4490 Velvet Sound premium DAC chip is used as the converter chip in the digital-to-analog converter, which thanks to its architecture reproduces the finest sound details. 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 resolution of DSD4 or DSD256.

Every signal that is passed from a DAC chip into the analog world must be filtered be filtered by a low-pass filter. Two of them are implemented in the DLP120: One for PCM audio and one for DSD audio, since different roll-off frequencies are required. 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, headroom, and sound.

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, SPL can ensure that they use the best sounding components.

VOLTAiR is the synonym for SPL's 120V Rail Technology within the Professional Fidelity series. The audio signals are processed with an unequalled ±60V DC, which corresponds to twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers.

VOLTAiR Technology reaches outstanding technical and sonic performances, especially in terms of dynamic range, headroom, and in reproducing the finest details and delivering a totally relaxed sounding audio experience. Music sounds absolutely natural.

Q: 1. Will this power a Sennheiser MKH 416 to connect to a rode wireless go II?

A: No, the Sennheiser MZA 900 P In-Line Preamplifier and Power Supply for EW Series Microphones will not work to connect a Sennheiser MKH 416 Shotgun Microphone to the Rode Wireless GO II Transmitter. To connect a microphone that requires 48V phantom power to a wireless transmitter, it would be suggested to use a portable phantom power supply such as the Denecke PS-1A Portable Single Channel 48V Phantom Power Supply (BH #DEPS1A) along with an appropriate adapter cable on the supply's XLR output connection: https://bhpho.to/3vYUjr9

Q: 2. I am trying to buy a 4x or 5x adaptor (tele) lens for iPhone2020SE... Does such a thing exist. My goal is to shoot a head&shoulders shot for a video blog from 6 to 8 feet away. Will a 3x lens suffice?

A: A 3x lens should be enough for what you are trying to do. We do not have 4X or 5X lens adapters.

Q: 3. It fits with Sennheiser 820?

A: The SLAPPA HardBody Pro Full-Sized Headphone Case (Diamond-Cut Nylon Laminate, Black) BH #SLHP99 will not hold the Sennheiser HD 820.

Q: 4. Will this fit Tascam TH-02 heaphones without squeezing bending the wire anchor too much?

A: They might fit but the wire isn't removable on the TH-02 so I wouldn't recommend it, it would be very close and might bend.

Q: 5. Do this devise will work with Sanken COS-11D XLR conector wired.To connect to Sennheiser G3 wireless system?.I will like to use my wired Sanken for wireless too, do this is possible?

A: This device has the special female mic connector (1/8 locking) for Sennheiser lavelier mics that are normally used with the G3 wireless system. It converts only those mics so they may be used with standard XLR mic cables. So this device has a male XLR connector that plugs into a standard mixer mic input. It is not suitable for connecting other kinds of mics with XLR connectors.

Q: 6. Could this device work with the Sanken COS-11D Omni Lavalier Mic(B&H # SAC11WNSETRB MFR # SAN-11DWNBKTRSE)? Thanks Renzo

A: MZA-900P is listed for compatibility with Sennheiser E 908B, E 908D, HSP 2, HSP 4, ME 2, ME 3, ME 4 and MKE 2 EW Gold microphones. We offer this model for the Sanken COS-11D with the 3.5mm connector for Sennheiser transmitters: B&H # AMEMP3.5

Q: 7. How is this product different than the Rode VXLR+ ? Voltage ? Impedance ?

A: The Rode VXLR Plus does not provide the same voltage that the Sennheiser provides. The Rode does 3-5v. For example: the Sennheiser ME 2 requires 7.5v. The Rode VXLR Plus would not supply that voltage.

Q: 8. Is this Telefunken smooth plate 12AX7 tube ? What country and year of production.? Thanks
