ALPHATON IA-2 INLINE TRANSFORMER XLRf-m W-GROUNDLIFT

Inline Transformer IA-2

The model IA-2 line matching transformers !S designed to properly match a low impedance
signal to a low impedance source. The advantage of "ground lift" switching allows to optmize
hum problems.

Weight 100 g
Dimensions diameter 17 mm, lenght 115 mm
 

The Stewart ADB-1 is a single channel active direct box that allows an unbalanced source to
directly feed a balanced input. Musical instruments, tape recorders, VCRs and sound projectors
can be run "direct" to the mixing console, avoiding unnecessary degradation of sound quality.
The ADB-1 operates on either phantom power or a 9-volt battery.

FEATURES:
Flat response
Low distortion
Low noise
Wide dynamic range
No transformer
RF protection on input and output
Switchable ground isolation
Flush mounted slide switches

2-channel DI box/splitter, active Converts 2 separate unbalanced line inputs (e.g. instruments) into 2 balanced XLR outputs for connecting a mixer Switchable to split mode (input 1 routes the signal to both outputs) Switchable input attenuation: +20 dB, 0 dB, -30 dB Ground-lift switch eliminates ground loop problems 2 signal inputs via XLR connectors 2 low-impedance XLR outputs Microphone phase can be switched Hi cut 8 kHz switchable Modern convex housing design Full rubber housing corners for safe operation Cables can be routed under the housing Operation with 9 V battery

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.

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.

You're serious about getting rid of all that excess noise on stage, but you've got so many line
instruments you don't know where to start. The ADB-4 from Stewart can take care of all your
high impedance problems. The ADB-4 is 4 active direct boxes, all in a module that only takes
up half a space on your keyboard rack. It's a rugged, durable piece of equipment that packs a
lot of DI power.
