Voltaire – 120V Rail Technology

• Voltaire is the synonym for our 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.
• Voltaire Technology reaches outstanding technical and sonic performances.
• Technically especially in terms of dynamic range and headroom and sonically especially in reproducing the finest details and delivering a totally relaxed sounding audio experience. Music sounds absolutely natural.

Comparisons

• These diagrams show how our VOLTAiR Technology compares to other circuits.
• The direct relation between the operating level and the maximum level is fundamental for the classification: the higher the operating level, the higher the maximum level a circuit can handle.
• And since virtually all essential acoustic and musical parameters depend on this relation, a higher operating voltage also has a positive impact on the dynamic range, distortion limit and signal-to-noise ratio.
• Do bear in mind that dB scales do not represent linear but rather exponential increases.
• A 3 dB increase corresponds to doubling the acoustic power, +6 dB corresponds to twice the sound pressure level, and +10 dB corresponds to twice the perceived loudness.
• When it comes to volume, the VOLTAiR Technology exhibits a performance, in regard to maximum level and dynamic range, that is twice that of common components and circuits given that its values are approximately 10 dB higher.
• THD measurements show a difference of more than 3 dB compared to the OPA134 at 36 V — in terms of sound pressure level, which corresponds to an improvement of more than 50%.
• The operating level most commonly used for audio equipment is +/- 15 volts.

Inputs

• The Performer s800 is equipped with XLR inputs (8, 12) for a balanced connection to a preamp.
• Full output power (2 x 285 W RMS into 4 ohms or 2 x 185 W RMS into 8 ohms) is performed at +6 dBu at the input.
• For unbalanced connection with e.g. RCA output connect Pin 3 to Ground in the external connector.

Slave Thru

• The input is passively fed to the SLAVE THRU (9, 13) output for bi-wiring applications.

Trim

• The input can be lowered with the TRIM switch (10, 14) from 0 dB to -5.5 dB in 0.5 dB steps.
• This is helpful if you want to use multi-speaker sets or speakers in a bi-wiring application.
• It allows to level speakers with different efficiency to equal loudness.

Bridge Mode

• In bridge mode, only the left input is used. The right input and the trim switches are deactivated.

Speaker outputs

• You can connect 4 or 8 ohms loudspeakers to the speaker outputs (11, 15) in stereo mode. In bridge mode, you can connect 8 ohms loudspeakers to the speaker outputs.
• You can either use the ø4 mm cable hole (screwable) or the banana plugs of the gold-plated loudspeaker binding posts.
• Make sure that you do not mix up the polarity of the speaker connections and that the power amplifier is switched off when you connect speaker cables.

Bridge Mode

The Performer s800 can be operated in bridge mode to combine both channel amps for maximum power (450 W RMS into at least 8 ohms). Only use the left input then.

• Set the BRIDGE MODE (7) switch to ON.
  Warning: Power down the Performer s800 with the mains switch (5) before you activate the BRIDGE MODE switch.

• In bridge mode, you only connect a single loudspeaker with at least 8 ohms to the Performer s800 power amplifier.

• Use the positive binding post (+) of the left speaker output to connect to the positive (+) input of the speaker.

• Use the positive binding post (+) of the right speaker output to connect to the negative (–) input of the speaker.

• In bridge mode, both the Trim switch and the right input are deactivated.

Protection circuits

The Performer s800 has protection circuits against DC (direct current) voltage at the output and against overheating.

DC Protection

• If DC is detected at the outputs, the Performer s800 automatically switches off. DC voltage can be an indication of a defective power stage.
• The PROTECT LED (2) on the front indicates that the protection circuit is activated and the power stage has been switched off.
• The Performer s800 does not automatically switch on again. It needs to be switched off manually with the main switch (5).
• Wait at least one minute before switching the Performer s800 on again.
• If the Performer s800 repetitively switches off due to a DC detection please contact your dealer.

Overheating protection circuit

• At about 70° C at the heat sink, the Performer s800 will switch off. After the temperature has fallen below 55° C, the amplifier automatically switches on again. The TEMP LED (2) on the front indicates the overheating.

AMP CTL (Amplifier Control)

• If you use the Performer s800 via AMP CTL with a SPL Phonitor x or SPL Director as a preamp, the Performer s800 can be switched between standby and operation together with the Phonitor x or the Director.
• Therefore you only have to connect the AMP CTL jacks (6) with a 3,5 mm mono mini jack cable.
• Warning: Use only SPL Phonitor x or SPL Director for amplifier control. Never connect other devices to the AMP CTL jack.
