PALMER AUDIO PAN02PRO Pro PAN 02 PRO – DI Box active

The Palmer PAN02 PRO is an active DI-box with outstanding additional functions. These include an unbalanced XLR input, in addition to the 3-way attenuator -10, -20, -30 dB and a switchable gain of 12 dB, connected with a maximum output voltage of +20 dBu. The Groundlift switch has a "lift" position allowing adjustments between a "soft and hard grounding" . The balanced output is achieved with a high quality transformer in the Mumetall housingthat was specially developed for this purpose. The PAN02 Pro can be powered either with a 9 V battery or 48 V phantom power. A two-colour LED indicates which source supplies the power.

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

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.

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.
