SPL P8 Eight-Channel Preamplifier

Expand your multichannel microphone recording capabilities with the P8 Eight-Channel Preamplifier from SPL. Rather than using less expensive integrated circuits (ICs), all eight of the mic preamps on this sleek rackmount unit are engineered with a discreet design featuring individual transistors that deliver up to 62 dB of gain for a neutral, open, and transparent sound.

• Microphone Inputs with Gain Control: The eight microphone inputs of the P8 are equipped with Neutrik XLR sockets featuring gold-plated contacts. The signal transmission is electronically balanced at a nominal level of 0 dBu. The gain control ranges between +8 and +62 dB.
• Phantom Power: Each of the eight preamplifiers has an individual 48V phantom power switch for use with condenser microphones.
• Pad: Each Pad switch in the respective preamplifier section attenuates the signal of the microphone input by -20 dB, so that even very high levels can be processed with the P8; well suited for use with loud percussion or brass recordings.
• Phase Reverse: The phase reverse function on every preamp reverses the polarity of the signal by 180°.
• High-Pass Filter: A 6 dB per octave high-pass filter is available in each of the eight preamp sections to reduce unwanted frequencies below 80 Hz.

• This version of the P8 features a pair of DB25 sockets, both providing analog outputs from all 8 mic preamps.
• The analog output signal can be connected to a multichannel A/D converter, for example, with the DB25 input common to this type of device, and in parallel to a second recording device. An additional external signal splitter for back-up systems during a recording session is therefore no longer necessary.

• Each P8 is carefully manufactured at SPL's production facility in Niederkrüchten on the Lower Rhine, Germany to ensure complete quality control.
• Many important components are installed on the circuit boards using through-hole technology to deliver the exemplary audio performance your sessions demand.
