Four (4) channel d.i. box, it can be used as a 4-line mixer as well. Each channel offers: 1 unbalanced 1/4\'\' jack input, volume pot, pan pot, ground lift switch, attenuation switch (0, -20dB, -40dB). It also has a headphone output, four (4) balanced xlr outputs and one (1) unbalanced rca aux out. Dimensions: 44,5mm x 230,6mm x 217mm. Weight: 1,75kg.

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.

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. Technical Data Frequency response 20 Hz - 20 KHz + 1 dB Impedance 600 : 600 Ohm THD K3 50 Hz = 0.5 % Level < + 6 dBm 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 |
