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.

Lovely sandals!
I highly recommend! These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.
