PALMER AUDIO PAN08 Pro PAN 08 – 19″ DI/Line Isolation Box 4 channels active

The PAN08 is a multifunctional device. Each of the four channels can be used independently as an active DI box, line isolation box or booster. The combination socket input accepts unbalanced and balanced signals. The output has dual transformer balanced XLR jacks (front and rear).

The signal level can be attenuated by 20 dB for microphone inputs, but can also be boosted in three stages by up to 18 dB for LINE inputs if necessary. With an output level of +12 dBu on a load of 600 Ω with 0.05 % THD / 40 Hz and an output noise level of less than -110 dBu, the unit meets even high professional standards. One special feature that is worthy of mention is battery power. The supply voltage may range from 9 to 18 V. Thus the PAN08 can also be used without mains power outdoors.

At dbx, when we do something, we do it right. So when we decided to create our new direct injection boxes, we didnʼt settle for the same old tired approach to direct box design. With our dbx name on the line, how could we? One look at our new dB10 Passive and dB12 Active direct boxes will tell you that these are clearly different. With their bullet-proof construction, and extraordinary audio performance to rival their looks, finally thereʼs a direct box worthy of the dbx name.

Utilizing custom dbx mu-metal-shielded audio transformers, high-quality Neutrik® connectors, and low-noise circuitry preserves the sonic integrity and true characteristics of the signal source. Both boxes include a pad switch that accomodates instrument, line and even speaker level signals. Take even more control of your sound by utilizing the polarity invert switch to set the phase relationship between the direct and mic'd sound.

As a professional, you donʼt have time for interference, so weʼve included a ground lift switch to solve potential hum and buzz problems due to ground loops. And between the combined shielding of the cast metal chassis and the custom-wound transformer, you can be doubly assured of a clean signal free from interference. All of this sits atop a solid, stable footprint, that will keep the box from being dragged around the stage, and the unique contoured underside allows secure stacking of multiple units.

So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx dB10 dB12 is for you.

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.

Phantom or battery powered in a rugged steel chassis
 
The ARX DI-PLUS 2 represents another major step forward in active direct boxes. Packaged in
a single channel stand-alone format, the DI-PLUS 2 represents a fresh look at active stereo
D.I. concepts.

Precision engineered
Ultra quiet, ultra clean circuitry delivers maximum headroom whatever the signal. Premium grade
components, plus an all-steel chassis gives excellent hum and noise specifications and superb
audio quality in a tough, roadworthy package. Accurate Left and Right channel level matching keeps
the stereo image centred.

Level control
The DI-PLUS 2 features two high impedance unbalanced inputs on the front panel, running to balanced
XLR outputs on the rear. A a global Pad switch drops inputs by 20dB, making it suitable for all applications
from the softest keyboard to the hottest broadcast levels.
 
Battery compartment
The revolutionary simple 'clamshell' action of the DI-PLUS 2 battery compartment makes battery changing
extremely easy, even on the darkest stages.
A 9v alkaline battery snaps into a PCB mounted battery holder for fast, secure location. No fragile battery clip
leads to break, no tools required, no screws to lose. Production crew heaven!
 
Automatic Phantom switching
The DI-PLUS 2 will automatically switch itself to the console's own Phantom Power, if available, and an LED
will indicate this mode. Turn the Phantom Power off and it will instantly revert back to battery mode.

Rugged all-steel case
A lot of direct boxes are fitted into brittle cast alloy cases. Not this one! The tough all-steel inner and outer
chassis of the DI-PLUS 2 provide excellent RF/EMF shielding while making it a sturdy, heavy duty unit that
is hard to dislodge, and hard to leave behind.

Whether you're a Studio or Live Sound engineer, installation contractor, or broadcast engineer, you want all
the dynamics,clarity and stereo information of the original sound source transferred to the mixing console.
The ARX DI-PLUS 2 provides a rugged, no-compromise solution to all stereo direct injection and signal
balancing requirements.

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.
