SPL Phonitor x Headphone Amplifier / Preamplifier

Great sound – for all headphones

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

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.

Headphones or Speaker

The OUTPUT switch turns the headphone amplifier into a preamplifier – simply switch from headphones to speakers.

1. In the center position (mute), no signal reaches the outputs.
2. The VU meters light up red.

To the power amplifiers or the active loudspeakers

• You can use the balanced via XLR sockets – for long cable runs.
• Unbalanced via RCA sockets.
• The source signal is always present at both speaker outputs.

The standby mode of devices with 12V trigger input can be switched on and off via AMP CTL.

This allows, for example, the SPL Performer s800, Performer m1000 or Performer s1200 power amplifiers to be ideally integrated into the set-up.

Source of joy

Up to five stereo sources can be connected to the Phonitor x:

• XLR
• RCA
• Via the optional DAC768xs:
  • USB
  • COAX
  • OPTICAL

The Phonitor x accepts a variety of different audio connections.

• Balanced via XLR
• Unbalanced via RCA jacks

Optional DAC768xs, three additional digital sources can be added.

• PCM audio is received in S/P-DIF format both coaxially (RCA) and optically (Toslink F06).
• Both PCM audio and DSD audio can be converted via USB.

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 x are necessary.
