SPL Phonitor xe Headphone Amplifier

Great Sound – for all headphones

The Phonitor xe offers connections for a standard headphone with a stereo jack plug and for balanced-driven headphones using a 4 pin XLR plug.

Thanks to the enormous output power, all headphones are driven effortlessly.

Thus, it plays out the advantages of the SPL VOLTAiR technology and rewards the listener with an honest, detailed and at the same time vivid sound experience.

Two Outputs

The Phonitor xe provides headphone outputs on the front and on the rear.

On the front, you switch between F (front) and R (rear).

This way, your favorite headphones remain firmly connected on the rear – without visible cabling on the front.

Optional DAC768v2

Up to six (6 !) stereo sources can be connected to the Phonitor xe:

• XLR
• RCA
• Via the optional DAC768v2 also:
  • USB
  • COAX
  • OPTICAL
  • AES

Phonitor xe accepts almost all audio connections.

• Balanced via XLR
• Unbalanced via RCA connectors

With the optional DAC768v2, four additional digital sources are added.

From USB to professional AES format, no wishes remain unfulfilled.

The DAC automatically picks up the sampling rate and resolution of the digital playback source.

1. No matter if a streamer, computer or CD player is connected.
2. No further settings on the Phonitor xe are necessary.

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 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 optional DAC768v2 for the Phonitor xe is equipped with the SLP120 – an analog “Super Low-Pass” filter with VOLTAiR technology.
