RADIAL Ice Cube Balanced Line Isolator

The Radial IceCube IC-1 is a balanced line level isolator designed to quickly eliminate hum and buzz problems in an audio system by simply inserting it into the signal path.

The Radial IceCube IC-1 is a balanced line level isolator designed to quickly eliminate hum and buzz problems in an audio system by simply inserting it into the signal path.

Measuring just over 4" x 1 ½" (10 x 4cm), the compact design begins with two super-duty glass-filled nylon XLRs at each end with heavy duty nickel-silver contacts that will not tarnish over time. Unlike other isolators that are made of plastic, the IceCube is made from solid 16 gauge steel and finished in a tough powder coat. The steel outer shell is not only more durable, it provides excellent shielding against electromagnetic fields radiated by power cables, dimmers, motors and power supplies - delivering consistently quieter results when deployed. This is augmented with a \'set & forget\' ground lift switch to eliminate hum and buzz caused by ground loops.

Inside the IceCube, a proprietary Eclipse transformer isolates the input from the output and blocks stray DC currents. While small transformers rarely perform well below 100Hz, the IceCube is exceptionally linear from 20Hz to 18kHz. It is also able to withstand up to +10dB at 20Hz with less than 0.01% distortion. It is a quick and easy problem solver that will eliminate noise without limiting the bandwidth or introducing phase shift, harsh sound or unpleasant artifacts.

These features combine to make the IceCube an ideal problem solver for the AV technician and audio engineer that work in the fast-paced world of live touring, AV rentals and system integration.

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 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.

The AC 275 is an active, phantom powered direct box. Unlike a passive DI where the frequency response of the signal can be altered depending on the connected impedance, an active DI buffers the input signal with an amplifier. This assures that the sound source will reach the mixer balanced and noise-free.

Housed in a cast alloy chassis, the AC 275 supplies two, high impedance, unbalanced 1/4" jacks and one low impedance balanced XLR jack. It operates with battery or phantom power.

Key Features
?	Active direct box
?	Allows a hi impedance unbalanced source to directly feed a low impedance balanced input
?	Flat frequency response
?	Connects guitar pickups, microphones or electric instruments to a recording or P.A. console without audio quality loss
?	Internal pad for speaker level input
?	Operates with battery or phantom power
?	Ground lift switch eliminates typical ground loop problems
?	Rugged, road-proof cast alloy chassis

Active 4-channel DI box. Each channel has a jack input with a parallel output for passing through the signal. An attenuation switch (-30 dB) allows either a line or loudspeaker signal to be connected.Active 4 x DI box, 19" format. Technical specitications identicl to the PAN-02, however, the PAN-03 is built for mains operation. All connections and switches are located on the front panel, an additional parallel XLR output is located in back. 19 inch rack-mount format, 1 rack space, 90 mm front to back.
