SPL P8 + Adc8 | 8-channel Mic Preamp W/ Adat Converter

P8 + ADC8 

8-Channel Mic Preamp W/ ADAT Converter

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.

8 Pristine Channels of Microphone Preamplification with Professional Features

• 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 also available in each of the eight preamp sections to reduce unwanted frequencies below 80 Hz.

Analog and Digital Outputs

• This version of the P8 features a single DB25 socket providing analog outputs from all 8 mic preamps. In addition, it features an 8-channel A/D converter and a pair of optical ADAT (TOSLINK) outputs that connect directly to the digital ADAT inputs on a wide range of audio interfaces.
• In 8-channel mode, conversion rates of up to 96 kHz are supported. In 4-channel mode, conversion rates of up to 192 kHz are supported.
• Conversion is handled by the highly acclaimed AKM AK5538 ADC chip, which, thanks to its architecture, reproduces outstanding sonic details.
• The wordclock connection panel contains a clock input and a clock output as well as a switch for terminating the clock input. The A/D converter processes standard incoming wordclock signals and generates them on the outgoing connector, thus ensuring rock-solid digital transmission and pristine sound quality.
• A USB service port on the A/D converter ensures that the digital interface can be easily maintained. The port is used to update the operating software (firmware) and is not intended for audio connections.

Made in Germany

• 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.
