The AR-416 is an active 4-channel direct injection unit.
Each channel includes:
High impedance of 1M Ohm.
* A ?" instrument jack per channel with both parallel and buffered link outputs on ?" jacks to feed into backline amps. * A low impedance XLR output which is active buffered, transformer-balanced, floating and capable of driving 600 Ohm over long cable runs. * A selectable 8kHz low-pass filter; polarity-reverse and earth-lift on “XLR side“. * 3-way selectable input attenuation (0dB, 20dB, 40dB pad). * An additional earth lift on the "jack side“.
The earth lifts on each channel have LED indicators to show true status and avoid confusion. The unit has total ground isolation with no significant crosstalk between channels and a very low noise floor. The unit is mains powered. |

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 |
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.

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.

Active DI-Box SM-60
The electronic Direct-Injection Box SM-60 allows direct connection of electronic music instruments such as keyboards, synthesizers, electric and electronic pianos, etc. with mixing consoles in PA-systems and in recording studios. The SM-6 is designed for applications, where a passive DI-Box does not perfom satisfactorily, i.e., where the output level of a passive DI-Box is too low for the microphone input section of the mixing desk. Because the input impedance of the SM-6 is above 5 MOhm, instrument outputs are not loaded or in any other way adversely affected. The voltage ratio from input to output is 1: 1 and is always sufficient for connection with any microphone input. Input connectors are 1/4" phone jacks, output connector is a Switchcraft D3M; output is 600 Ohms, transformer balanced. The output level may in certain cases overload microphone inputs - the line input section of the mixing console must then be used for connecting the SM-6. The unit operates with a 9 V battery or phantom powering from 24 to 48 volts.
