SPL Audio P8 Microphone Preamp

SPL P8 Overview.

SPL’s Crescendo 8 eight-channel preamp was a great hit at. The business has now condensed the musical essence of their high-end multichannel preamp into the P8, a compact 8-channel preamp that provides excellent value for money. You still get SPL’s discrete transistor circuit design—no ICs here! Each of the eight channels contains a full-featured mic preamp, replete with a rotary gain control and switches for enabling phantom power, a 20 dB pad, polarity reversal, and a highpass filter.

The pure-analog P8, which includes SPL’s optional eight-channel A/D converter with ADAT outputs, may be digitally linked to your audio interface. We’ve rarely seen so much capability crammed into a compact 1U 19-inch rackmount chassis. When you use the SPL P8 in your studio or live setup, you will be pleasantly surprised by its performance, adaptability, and value. We surely are.

Microphone Inputs With Gain Control: The P8’s eight microphone inputs include Neutrik XLR sockets with gold-plated contacts. The signal transmission is electronically balanced to a nominal level of 0 dBu. The gain control runs from +8 to +62 dB.

Phantom Power: Each of the eight preamplifiers features a separate 48V phantom power switch for use with condenser mics.

Pad: Each pad switch in the corresponding preamplifier section attenuates the microphone input signal by -20 dB, allowing the P8 to handle even extremely high levels; this is ideal for usage with loud percussion or brass recordings.

Reverse Phase: Every preamp features a phase reversal capability that reverses the signal’s polarity by 180°.

High-pass filter: Each of the eight preamp sections features a 6 dB per octave high-pass filter designed to reduce undesirable frequencies below 80 Hz.

Pure analog, optional digital output.

The P8’s eight mic inputs feature rear-panel Neutrik XLR connectors with gold-plated contacts. Signal transmission is electronically balanced at a nominal level of 0 dBu. The P8 provides eight line-level signals via duplicate DB-25 connectors on the back panel, allowing for flexible downstream routing. You can connect one of these to a multichannel A/D converter with DB-25 ports, then run the analog outs in parallel as a backup or through a separate effects chain to another recording device, eliminating the requirement for a signal splitter.

As previously indicated, the P8 may be equipped with an eight-channel A/D converter. With this version, digital outputs replace the duplicate analog eight-channel DB-25 output, allowing the P8 to be connected directly to an audio interface’s ADAT inputs.

High-performance A/D converter options

The P8 with ADAT employs the renowned AKM AK5538 ADC chip, which translates analog audio with sampling rates of up to 192 kHz to provide extremely detailed digital output via ADAT optical (TOSlink), which is compatible with a wide range of audio interfaces. The converter’s ability to work in single, double, or quad-speed modes allows you to choose the number of output channels and sample rates. Whatever speed mode you choose, the P8 will continue to output eight analog channels via the DB-25 connection. The A/D converter has word clock I/O, a switch for terminating the clock input, and a USB service connector for firmware updates.

Made in Germany.

Each P8 is meticulously crafted in SPL’s production plant in Niederkrüchten, Lower Rhine, Germany, to ensure perfect quality control.

Many critical components are mounted on circuit boards utilizing through-hole technology to provide the exceptional audio performance that your sessions require.
