Die ART Dual ZDirect und ihr einkanaliges Gegenstück sind hochwertige passive Direct-Boxen, die für den Anschluss von Instrumenten-, Line- oder Lautsprecherpegel-Signalen an symmetrische Eingänge entwickelt wurden. Die Schaltung verfügt über einen Hochleistungs-Audiotransformator, der einen flachen und weiten Frequenzgang bietet und gleichzeitig hohe Signalpegel ohne Sättigung verarbeitet. Sie bietet eine vollständige elektrische Isolation zwischen Ein- und Ausgang, wodurch Brummen und Rauschen durch Erdschleifen effektiv eliminiert werden. Das Gerät verfügt über einen schaltbaren Tiefpassfilter zum Absenken unerwünschter Hochfrequenzgeräusche und einen Phasenumkehrschalter zur Signalausrichtung. Das robuste Aluminiumgehäuse ist für den harten Einsatz in Live-Sound- und Studioumgebungen konzipiert. Es sind keine spezifischen Kooperationen bekannt; es handelt sich um ein eigenständiges Design von Applied Research & Technology.

The ART Dual ZDirect and its single-channel counterpart are high-quality passive direct boxes designed to connect instrument, line, or speaker level signals to balanced inputs. The circuit features a high-performance audio transformer that provides a flat and wide frequency response while handling high signal levels without saturation. It offers complete electrical isolation between input and output, effectively eliminating hum and buzz caused by ground loops. The unit includes a switchable low-pass filter to roll off unwanted high-frequency noise and a phase invert switch for signal alignment. Its rugged aluminum case is designed for heavy-duty use in both live sound and studio environments. No specific collaborations are noted; it is a proprietary design from Applied Research & Technology.

Passive Direct Box

The ART Stompwatch professional stage clock and set timer is the ideal solution for artists needing to accurately adhere to set times and critically manage set flow. Packaged in a rugged all metal housing and using the guitar ‘stompbox’ form factor, the Stompwatch uses highly visible four digit display easily viewable on virtually any stage. The footswitchable stop / start button triggers set clock for accurate set timing, and toggles between timer mode and standard clock mode, allowing complete show time management from the stage.

Stompwatch

The DTI (Dual Transformer/Isolater) is a high quality totally passive audio interface that uses a pair of high performance transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The DTI’s audio transformers have an extremely flat and wide frequency response and can handle high signal levels while an isolated balanced output.

DTI – Dual Transformer/Isolator

The Zdirect is a high quality totally passive interface that lets you connect
instrument, line, or speaker level signals to a mixer or other balanced input
thru a high performance audio isolation transformer. The high impedance
single-ended 1/4” input is converted by the transformer into an isolated balanced
low impedance signal source. The Zdirects audio transformer has an extremely
flat and wide frequency response and can handle high signal levels while still
maintaining an isolated balanced low impedance output. This gives the Zdirect
a very clean and neutral sound with a wide variety of signal sources and over
long signal runs in high noise environments
