Description

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.

Standard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High-impedance input; higher output level than with a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out -4 dB). Maximum output impedance with phantom power operation +10 dB. Output: transformer balanced. The special "floating ground" circuitry enables ground lift even during phantom power operation. Metal case 110 x 73 x 42 mm.

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.

Tube-buffered DI-Box DI-1000

The Tube-Buffered DI-Box DI-1000 allows the extraction of all the musical details of
musical interfaces without degrading the sound. This can only be achieved by
providing a very high input impedance to avoid any loading of instrument pickups.This
design approach allows seemingly infinite headroom to preserve the real dynamic range
of the interfaced instruments.A vacuum tube enables all these goals to be achieved
without any compromises in sound quality.The sonic difference between a standard
DI-Box and the Tube-Buffered DI-Box is comparable to the musical resolution difference
between a standard microphone and a studio microphone.One of the best transformers,
the very transparent sounding JENSEN JT-DB-E, was chosen providing complete ground
isolation. The parameters of this transformer, like frequency response, phase response,
group delay and geadroom capabilities, play a vital part in the performance of this DI-Box.
 
Technical Specifications
Input
The signal of the instrument is directly fed to the tube circuit with > 20 MOhms input
impedance to prevent any signal degradation, inevitable in traditional designs.
Buffered Output“
The second stage of the vacuum tube is used to buffer the signal and lower the output
impedance to < 8 kOhms. This unity gain output allows for cable runs of 10 meters
without loosing high frequency information.
Boost circuit
The boost circuit increases the signal send to the output transformer by 15 dB. This may
be useful for instruments with extremely low output, but decreases headroom capability
to 6 Volt rms. Under these circumstances the signal may be clipped, concerning the output
transformer?s signal, which gives you 2nd harmonic tube-like distortion. This distortion
normally does not occur - but is sometimes desirable, being the reason for this special feature.
Unity circuit
The unity circuit feeds a low distortion unity gain signal to the JENSEN output transformer.
This gives the best possible sound quality.
Ground-lift“-Switch
This front panel mounted switch allows complete ground and electrical isolation between the
direct injection box and the console or recording device.

Construction details
Double sided glass fibre contacted PCB with 70 mm copper plating. 1% metal film resistors
and the finest polypropylene capacitors are used in the signal path. MIL type Switchcraft jacks
and high performance switches ensure flawless operation. The power supply is optimised via
measurement quality toroid transformer and a low impedance design to ensure the lowest
possible noise. Through a double sided PCB all parts are roadworthy secured. A waterclear
blue LED perfects the aesthetics of the DI box.

Palmer PAN 03
19" DI Box 4-Channel active

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.
