SPL P8 + ADC8

The SPL P8 is a high-end, eight-channel microphone preamplifier designed to offer pristine audio quality for multi-channel recording. Each of the eight preamps is built with discrete technology, ensuring a signal path free from integrated circuits (ICs). This design, utilizing individual transistors, is tailored for audiophiles and professionals who prioritize sound purity, contributing to the unit's open and transparent sonic characteristics. The preamplifiers provide a flexible gain range from +8 dB to +62 dB, making the P8 suitable for a wide range of microphones, including those requiring higher gain.

Expand your multichannel microphone recording capabilities with the P8 Eight-Channel Preamplifier with ADAT Converter 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. This version of the P8 is equipped with a built-in eight-channel A/D converter, allowing you to easily interface with compatible audio interfaces supporting digital audio via ADAT.

Key features include individual controls for each preamp, such as a 48V phantom power switch for condenser microphones, a 20 dB PAD for handling loud sources, a high-pass filter to eliminate subsonic noise, and a phase inversion function. For digital workflows, the P8 can be equipped with an optional eight-channel ADAT converter, allowing seamless connection to digital audio interfaces. This versatility makes the P8 ideal for both analog and digital recording environments, delivering unparalleled audio performance while maintaining ease of integration into various studio setups.
