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.

Behringer MIC-2200 2-Channel Tube Microphone Preamplifier-Line Driver-DI Box

The MIC2200 is the ideal extension to your console, MIDI setup or hard disk recording system. Its integrated parametric EQ?s give you extra sound-shaping power, while its built-in tube adds warmth and transparency to your signal. In addition, the ULTRAGAIN PRO features direct injection and level conversion functionality.

EWI PDI-100 PARA ACOUSTIC DI Box   This is a medium grade professional application Para Acoustic Active DI, which will work well on instruments with passive pickups or active pickups.  The construction is reasonably rugged and the components are well suited for the application yielding results that are typically acceptable for all but the most discerning artists.    The on-board tone and volume controls give the operator a lot of choices in shaping their sound prior to sending the signal to the mix console.  This allows an artist to use this device in-place of or in addition to a traditional stage amp for their instrument.  This is an excellent choice for IEM bands, or bands that like to keep their stage volume low.   This item is typically used to split the instrument signal going to a stage amp so a feed can be sent also to the mix board, or be used as a stand-alone instrument pre-amp.  It is equipped with a ¼” jack for input, a 1/4" jack for output to a stage amp, one XLR jack for the send to the board and a TRS jack for inserting an FX device.Since this is an active D.I. box, it needs to be powered which can be done either with Phantom Power from the mix board, or with the supplied internal 9v battery.  The battery is fairly easy to change by removing one screw in the bottom of the case.

ARX is proud to introduce the e-pre - the ultimate microphone pre-amp for
hard disk recording, designed by audio professionals, not computer engineers.
The all-new e-pre is so much a part of your system that it fits right into a spare
5?" slot in your computer case! It's the perfect tool for all your day-to-day
recording requirements. No equipment racks to plug in, no masses of cabling to
connect - the e-pre is ready and waiting when you need it.
The e-pre is a studio quality microphone pre-amp using the same internal components
as high end mixing consoles, built into a compact, computer friendly package.
It has controls for:
Input Gain - fully variable from 10dB through to 60dB to suit all types of microphones,
plus switchable 48 V Phantom Power to enable condenser microphones to deliver
their best.
A Contour control for EQ sweetening, providing fast, easy access to a whole range
of useful EQ curves
Output level control - fully variable to match the e-pre's output to the input of the sound
card. From -10dB consumer cards through to +4dB for professional sound cards, the
e-pre can handle it.
Multiple output connectors match up with any kind of sound card, including mini jacks,
standard jack, RCA (phono) plugs, and even a connector to link to the internal CD ROM
audio input of your sound card (if fitted).
We've even fitted a 12 VDC input connector on the rear to enable the e-pre to run from an
external power supply if required (eg for use with notebook computers or stand-alone use).

Any way you look at it, the e-pre by ARX is the total professional microphone pre-amp for
all your hard disk recording needs

e-pre Benefits
Professional Balanced XLR mic input
True 48v phantom power
Runs into the Line input of ANY sound card - uses the card you've already paid for
High headroom = clean recordings
Smart EQ
Compatible with non-computer audio equipment
Professional performance and specs in a user friendly package
