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.
| 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.

The PreSonus HP60 is the most flexible and advanced headphone amplifier system available for professional and project recording studios as well as live sound in-ear monitoring systems. Loaded with six independent,
loud and clear headphone amplifiers, the HP60 features dual stereo inputs as well as external input, for each
channel allowing you to mix between three stereo audio streams (mix A, mix B, and external input). Stereo output is also available on each channel to send line level headphone channel mixes to additional headphone amplifiers or monitor systems. Each channel features headphone level, mix control between A and B inputs, external input volume, mute and mono. The HP60 also features talkback via external XLR microphone input. Common set up of the HP60 in a recording session is to send the main control room mix to input A. Send the click track to input B. Send the each band member direct recording input to each channelʼs external input (more me). This will allow each band member to create a mix between the main mix, the click track and themselves. The HP60 is the ultimate headphone amplification system delivering loud and clear headphone mixes for real-world recording situations.
Features:
-Six independent ultra low noise, high output headphone amplifiers (150 mW per channel)
-Two sets of stereo inputs (A and B) with balanced TRS connectors
-Stereo external input point on each channel for "more me” with trim control
-Mix control between inputs A and B
-Talkback with external XLR microphone with control
-Direct stereo line output on each channel

SONIC EXCELLENCE
The Avalon U5 Pure Class A instrument DI & preamplifier is the most powerful direct box
available today. Designed to optimize absolute signal integrity and musical performance,
the U5 includes many features and sonic excellence unequaled by lesser designs. The
U5 is ideal for bass guitar and acoustic instruments, electric guitars, keyboards, synthesizers
and low output pickups.
Features include state-of-the-art, high input impedance input stage for zero load effect on
sensitive pickups and keyboards, 100% discrete, Pure Class A signal amplifiers, practical
user features and rugged hardware designed to deliver true high performance audio for many
years.
DESIGNED FOR DEEP & CONTROLLED BASS
Avalon U5 DI-preamps have been in use around the world since 1995. They have found their way
into the world's leading musicians rigs and recording sessions and been featured on thousands
of the best selling (and sounding) albums and live performances.
MINIMUM SIGNAL PATH DESIGN
The U5 includes a variable gain Class A preamplifier to boost low level pickup signals and a high
level speaker input for capturing the live sound of the instruments amplifier. Six passive tone-EQ
curves are also included to enhance a variety of acoustic and electric instruments. A high-cut switch
eliminates unwanted acoustic pickup and high frequency noise, while a headphone monitor amp
has been included for personal listening. Twin DC coupled Class A output amplifiers drive both low
level microphone preamp inputs and high level +4dB inputs for direct to tape recording or processing.
The active-to-thru switch selects either the instrument input directly or sends the boosted-equalized
signal to the amplifier via the front panel jack. A ground isolation switch eliminates any possible earth
loop or AC buzz problems with complete safety.
