RADIAL X-AMP Active Re-Amplifier

• Active Reamp® with two outputs
• 100% discrete class-A signal path
• Transformer isolated to eliminate noise
• Variable 'set & forget' level control

The Radial X-Amp is an active Reamper™ that allows the engineer to play a pre-recorded track back through guitar amplifiers and pedals. This opens the door to explore new musical sounds and spur on the creative process so that your recording stands out.

Using the X-Amp is easy: start by recording a dry track using a high quality direct box like the Radial J48. Send the new track from your recorder via the X-Amp to your guitar amps, effect pedals or combinations thereof. Once the basic track has been recorded, replacing or adding tracks can be done well after the session player has gone home. This eliminates tiresome repetition and assures a fresh vibrant performance on the final recording. Furthermore, by driving two amps at the same time, new sounds and textures can be created while allowing you to make artistic decisions as the recording progresses.

Following the critically acclaimed Radial JD7 Injector, the X-Amp employs a unique class-A circuit design that has been optimized for use with guitars. Features include balanced line level input with LED peak indicator and level control, class-A circuit topology for optimal reach and frequency response, a transformer isolated output to eliminate hum and buzz caused by ground loops, a 180º polarity reverse switch to bring both amps into phase, and a dual ground lift switch for noise-free operation.

As with all Radial products, the X-Amp is built like a tank to provide years of trouble-free performance. An internal I-beam skeleton provides maximum protection against external stress which could cause solder points to fail. This is supplemented with an innovative bookend design that creates a protective zone around the switches, potentiometer and connectors. A full bottom no-slip pad performs double duty by keeping the X-Amp from sliding around when placed on a vibrating amplifier while also providing electrical and mechanical isolation. Reamping works equally well on bass, keyboards, drums and voice. Once you start Reamping, you will never record any other way.

The Radial X-Amp… the active Reamp® for professional recording engineers.

The alphaton Direct Injection-Box SM-50 allows direct connection of electric guitars,
electric bass, and electronic music instruments with mixing desks of PA systems
and of recording studios.
The SM-50 reduces the amount of microphones used on stage, thus improving gain
before feedback.
Coloration of sound is avoided. Clean signal without interference from other instruments
eases the job of the recording engineer. The use of a strong aluminium die-cast box allows
trouble-free function for a number of years even under adverse conditions. Double grounding
(hum) can be eliminated by activating the built-in ground-lift switch. Isolation voltage between
input and output is 2500 volts, against ground 1500 volts (with ground-lift switch activated).
The box thus complies with toughest safety standards.

Passive DI box especially designed for guitars.

The PDI09 can be connected between an effect device or amplifier and the mixing console. The PDI09 is not suitable for direct connection to a guitar. Integrated filter circuits simulate the authentic "speaker" sound. Tone can be varied between "Mellow“, "Normal“, or "Bright“.

Technical specifications:

• Input: 6.3 mm jack with parallel "THRU" socket
• Output: male XLR transformer balanced
• Attenuator: (Level switch) 0 dB for line signals, -15 dB for small amps up to 10 w, 30 dB for large amps up to 200 w
• No battery necessary

The ARX DI-PLUS 2 represents another major step forward in active direct boxes. Packaged in
a single channel stand-alone format, the DI-PLUS 2 represents a fresh look at active stereo
D.I. concepts.

Precision engineered
Ultra quiet, ultra clean circuitry delivers maximum headroom whatever the signal. Premium grade
components, plus an all-steel chassis gives excellent hum and noise specifications and superb
audio quality in a tough, roadworthy package. Accurate Left and Right channel level matching keeps
the stereo image centred.

Level control
The DI-PLUS 2 features two high impedance unbalanced inputs on the front panel, running to balanced
XLR outputs on the rear. A a global Pad switch drops inputs by 20dB, making it suitable for all applications
from the softest keyboard to the hottest broadcast levels.
 
Battery compartment
The revolutionary simple 'clamshell' action of the DI-PLUS 2 battery compartment makes battery changing
extremely easy, even on the darkest stages.
A 9v alkaline battery snaps into a PCB mounted battery holder for fast, secure location. No fragile battery clip
leads to break, no tools required, no screws to lose. Production crew heaven!
 
Automatic Phantom switching
The DI-PLUS 2 will automatically switch itself to the console's own Phantom Power, if available, and an LED
will indicate this mode. Turn the Phantom Power off and it will instantly revert back to battery mode.

Rugged all-steel case
A lot of direct boxes are fitted into brittle cast alloy cases. Not this one! The tough all-steel inner and outer
chassis of the DI-PLUS 2 provide excellent RF/EMF shielding while making it a sturdy, heavy duty unit that
is hard to dislodge, and hard to leave behind.

Whether you're a Studio or Live Sound engineer, installation contractor, or broadcast engineer, you want all
the dynamics,clarity and stereo information of the original sound source transferred to the mixing console.
The ARX DI-PLUS 2 provides a rugged, no-compromise solution to all stereo direct injection and signal
balancing requirements.
