Mastering Grade Listening
For more than 30 years SPL is developing professional audio devices. Recording studios around
the world rely on their outstanding sound quality. Mastering studios in particular place the highest
demands on audio performance as they put the nishing touches on music productions – with
SPL 120V rail technology.
In our Professional Fidelity series we call this unsurpassed technology
“VOLTAiR” technology. It lets you experience music on the same level as the
mastering engineer.

Director
Professional Fidelity
Pro-Fi Series
DA Converter and Preamplier
The Director is a reference stereo preamplier with an extraor-
dinary DA converter designed in VOLTAiR technology.
The Director is the heart of the stereo to which all compo-
nents are being connected: the phono preamplier, the CD
player –digitally or analog–, the computer or media player via
USB, the headphone and power ampliers.
Volume is controlled in the analog domain to avoid shrinking
bit resolution at lower listening levels. Both volume and
source selection can be controlled with any IR remote.
• 120 V rail preamplier with integrated DA converter
• Four digital inputs: USB, AES/EBU, coaxial, optical
• PCM up to 384kHz
• DSD up to DSD2 (Double Rate DSD, DSD 128)
• Two analog inputs (2 x RCA) and outputs (XLR, RCA)
• Analog volume control with motorized ALPS “Big Blue”
potentiometer
• Remote controllable volume and source selection (Director
learns any IR remote control commands)
• AMP CTL connection to Performer power amplier for
coupled on/o switching
• Frequency range (analog): 4 Hz to 300 kHz
• THD: 0,0008% (analog), 0,0004% (digital)
• Dynamic range: 137,6dB (analog), 120,8dB (digital)
• Windows® driver, Apple class compliant
• Stand-by/power on switch
• Linear power supply with toroidal transformer
• Made in Germany

Phonos
Professional Fidelity
Pro-Fi Series
RIAA Phono Preamplier
Phonos is a phono preamplier designed in VOLTAiR tech-
nology for record players using either moving magnet (MM) or
moving coil (MC) cartridges.
The equalization curve is according to RIAA and suitable for
all vinyl records since 1954. The RIAA equalizer is as designed
by Douglas Self.
With up to 70 dB of gain for MC cartridges and 51 dB of gain
for MM cartridges Phonos belongs to the most powerful
phono preampliers.

• RIAA equalization (aer Douglas Self)
• Suitable for MM (Moving Magnet) and MC (Moving Coil)
cartridges
• Max. preamplication gain: 51 dB (MM); 70 dB (MC)
• Capacitances for MM: O, 150 pF, 220 pF and 330 pF
• Impedances for MC: 100, 220, 470; 2k2, 4k7 and 10 kohms
• Styroflex condensers used throughout the RIAA equalizer
• Switchable Gain: Normal, -10 dB, +4 dB
• Gold-plated RCA in- and outputs
• Audio ground connection for record player
• Switchable rumble lter (Subsonic)
• Linear power supply with toroidal transformer
• Made in Germany

Phonitor x
Professional Fidelity
Pro-Fi Series
Headphone Amplier and Preamplier
The Phonitor x is the ultimate amplier designed in VOLTAiR
technology for headphones operated both balanced and
unbalanced.
The Phonitor Matrix delivers the most realistic playback on
headphones. As almost all music was mixed for speaker play-
back the Phonitor Matrix lets you experience music on head-
phones as being played back through speakers.
The Phonitor x is also a mastering-grade preamplier that can
drive power ampliers or active monitors.
• 120 V rail headphone amplier and preamplier
• For balanced and unbalanced headphones (> 10 ohms)
• Balanced and unbalanced analog I/Os (XLR and RCA)
• Optional 192 kHz/24 Bit DAC with USB, coax and optical
inputs
• Windows® driver, Apple Class compliant
• Phonitor Matrix for speaker-equivalent playback on head-
phones with Crossfeed and Speaker Angle adjustment
• Motorized ALPS “Big Blue“ Volume potentiometer (IR
remote controllable – learns any IR remote control)
• Laterality control: super-ne balance control
• Mono switch function
• AMP CTL connection with Performer power amplier for
coupled on/o switching
• Maximum output power: 2 x 3.7 W (120 ohms)
• Frequency response: 4 Hz - 300 kHz
• THD+N: 0.00091 % (HP), 0.00085 % (Line)
• Dynamic range: 135.5 dB (HP), 136.3 dB (Line)
• Linear power supply with toroidal transformer
• Made in Germany

Phonitor e
Professional Fidelity
Pro-Fi Series
Headphone Amplier
The Phonitor e is a straight-forward and powerful headphone
amplier designed in VOLTAiR technology. Its feature set is
reduced to the essential: ampliers for balanced and unbal-
anced headphones, analog volume control, source selection
und Phonitor Matrix.
The Phonitor Matrix is condensed into two presets repre-
senting their most common settings. As almost all music was
mixed for speaker playback the Phonitor Matrix lets you expe-
rience music on headphones as being played back through
speakers.

Performer s800
Professional Fidelity
Pro-Fi Series
Power Amplier
The Performer s800 amplier is an ultra-compact power
amplier. Thanks to the VOLTAiR technology this power ampli-
er has absolute control over the speakers up to their load
limits.
In stereo operation this bi-polar transistor power amplier
delivers up to 2 x 285 W into 4 Ω speakers. In bridge mode it
delivers 450 W into a 4 or 8 Ω speaker.
The Performer s800 is an entirely analog design which
delivers a more natural sound compared to digital ampliers
or ampliers with switching power supplies.
• 120 V rail bi-polar transistor power amplier
• 2 x 285 W into 4 ohms; 2 x 185 W into 8 ohms (stereo)
• 450 W into 4 or 8 ohms (bridge mode)
• Toroidal transformer with 855 VA
• 40800 µF capacitance for faithful reproduction of impulse
peaks
• Direct slave through of the input (e.g. for bi-wiring)
• Input trim for attenuation up to -5.5 dB in 0.5 dB steps
• Gold-plated loudspeaker binding posts with protection
covers
• Neutrik XLR connectors for balanced in- and outputs
• AMP CTL connector for remote power on/o switching (e.g.
with Director or Phonitor x)
