  • Ultra compact phono preamplifier and equalizer
  • Proper RIAA equalization
  • RCA inputs and outputs
  • 6.3 mm stereo headphone output connector
  • Sturdy metal housing
  • 12 V AC/DC adapter included

The LD Systems PPA 2 is a very compact analogue phono preamplifier, which equalises the extremely low output signal of conventional turntables to RIAA standards. It allows you to connect to devices without any phono input, such as mixers, PA power amplifiers or sound cards. The phono inputs are designed as RCA jacks, just like the line outputs; the PPA 2 also has a screw terminal for the ground conductor of the turntable and a 6.3 mm stereo jack for connecting a headset. The THD factor of the preamplifier is below 0.05% and the channel separation is -75 dB. The LD Systems PPA 2 uses a 12 V AC adapter; a bright LED indicates the power supply on the top of the sturdy metal chassis.

Applications

Console input extending for both Digital and Analog mixing

Mic Pre-amps for ADAT/ Hard Disk/ Multitrack Recording
 
Innovation
If you love your compact Digital (or Analog) mixing console, but wish it had
more microphone inputs, ARX has the solution ? the 8 Pre: eight channels
of superb sounding Microphone Pre-amps in a compact 1 RU chassis.
The 8 Pre is the ideal console extender for those times when you need more
microphone inputs. Now you can put those unused line inputs to good use,
and who knows - the 8 Pre pre-amps sound so good that you?ll probably end
up using them all the time instead of the ones that came with your mixer!
Superb Audio Quality
The 8 Pre?s ultra low noise figures come from extensive use of premium
components plus care and attention to board design and layout. The result is
superb, transparent audio quality and the headroom to handle anything that a
mic can throw at it.
Gain is adjustable from 20 db through to 60 dB via a trim control on the front
panel, plus we?ve included a ?20dB Pad switch to tame the hottest condenser
mic output if required. The Clip status LED lights up 1 dB before the onset of
clipping, just to warn you you?re getting close.Phantom power is switchable in
banks of four channels: 1 through 4, 5 through 8. A Phase reverse switch is also
provided on each pre-amp channel to eliminate any close miking problems.
In short, the ARX 8 Pre is the mic Pre-amp that you?ll wish the console manufacturer
had used. It provides a unique solution to today?s multiple Mic Pre-amp requirements.

Vacuum Tube Mic Preamp. 12AX7 Vacuum Tube. +48V Phantom Power, 20dB Pad. This premium tube mic/line preamp features an integrated limiter for studio, live and hard disk recording applications. It features a carefully-selected 12AX7 vacuum tube with Behringer's UTC technology for exceptional warmth and lowest noise. Using the MIC100 is a great way to eliminate the "dull" sound of standard digital recorders & sound cards. Also, it perfectly complements studio-grade condenser mics. When used as a high-end DI-box, it ensures outstanding signal integrity. Features also include a phase reverse switch, +48 V phantom power, a 20 dB pad, and balanced I/O. The heart of the Tube Untragain is an extremely low-noise microphone preamp circuitry that uses discrete components and produces a highly trans-parent sound. In combination with Behringer's tube technology, the operational amplifiers 4580 and a sophisticated circuit topology, the Tube Untragain yields excellent noise and distortion properties. The innovative UTC circuitry that has been developed by our engineering team offers an abundance of sound-shaping possibilities. Absolute musicality was Behringer's major goal when we designed the Tube Untragain. The result is a device that, thanks to our tube circuitry, lends an incredible punch to percussion instruments. On the other hand, instruments that are rich in upper harmonics will receive more transparency. The sound will be warm, detailed and brilliant.
