PRESONUS BLUE TUBE DP – TWO-CHANNEL MICROPHONE-instrument PREAMPLIFIER

Description

The new BLUETUBE DP two channel microphone/instrument preamplifier with Dual Path technology delivers the best of both worlds offering a solid state preamplifier stage and a tube preamplifier stage in each channel. This new Dual Path feature delivers the most flexible preamplifier in its price range by delivering both fat warm tube tone or invisible solid state transparency. Each channel of the BLUETUBE DP includes a -20dB pad, polarity reverse, 80Hz filter, and +48v phantom power. Front panel controls include solid state GAIN control and switchable on/off TUBE DRIVE. When the TUBE DRIVE is clicked off, the tube preamplifier stage is bypassed delivering ultra-quiet and transparent preamplification. The front panel also includes illuminated analog VU meters for each channel for easy visual monitoring. The BLUETUBE DP's inputs are professional-quality Neutrik Combo connectors for inputting both XLR and 1/4' TS sources. Outputs include both XLR and TS jacks allowing for ultimate flexibility. The PreSonus BLUETUBE Dual Path is great for enhancing all types of microphones including condensors, dynamics and ribbons, as well as instruments including keyboards, acoustic and electric guitars and bass. The BLUETUBE DP is the perfect front-end preamplifier for any project studio delivering a wide range of sounds and tonality all at an amazingly affordable price.   Technical Specifications

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.
