SPL P8 - Eight-Channel Microphone Preamp
SPL P8 - Eight-Channel Microphone Preamp
P8 is equipped with eight identically designed microphone preamplifers. All eight preamps have a discrete design – without ICs, made of individual transistors. This is typical for absolute high-end preamplifers and is one of the main reasons for the outstanding sound.
Besides an analog gain control for adjusting the preamplifcation, each of the eight preamps features an individually switchable phantom power supply (48 V), a PAD switch, a phase inversion function and a switchable analog high-pass filter.
P8 paves the way for high-quality multi-channel recording sessions.
Microphone inputs
The eight microphone inputs of the P8 are equipped with Neutrik XLR sockets and gold-plated contacts. The signal transmission is electronically balanced, at a nominal level of 0 dBu.
Line outputs (analog)
In the version without optional AD converter, P8 has two DB25 sockets at the output stage. Both of these provide the analog line level output signal from microphone preamps 1 to 8.
The analog output signal can be connected to a multi-channel AD 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 thereforeno longer necessary.
