      ART T8 8-Channel Transformer Isolator (154021)
Availability:  


Say goodbye to hum with the T8.

High-quality passive audio interface uses 8 transformers to separate input and output signal grounds, isolating 2 systems and reducing hum and ground-loop noise. The T8's audio transformers have flat, wide frequency response and handle high signal levels while maintaining an isolated balanced output. This allows a clean, neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed for 600 ohm to 100kOhm impedance. XLR, 1/4", and RCA connections on all inputs and outputs offers connection versatility. Reversible mounting ears allow either the XLRs or the 1/4" and RCA jacks on the front. The T8 fits easily into virtually any audio system and is a clean patch point between all types of systems.

The T8 works great as an interface between a computer-based audio workstation and a monitor system, isolation on long cable runs in a fixed installation, isolation of multiple signal sources from recording equipment, or a safer connection between 2 audio systems. Comes in a road-rugged 19", 1U all-steel black case.

    As reviewed by BG on 5/7/2010

    Play mostly at home. Have collected 4 amps over the years and wanted to make life easier by connecting my amps and pedals thru a foot switcher. I then discovered gound loop hum. After some research and listening to an interview with Sheryl Crows' guitar tech, I discovered I needed an audio ground loop isolator. I checked out several other products and even purchased some mid priced isolators that only had RCA connectors (and required adapters). I decided to try this unit out. It is built well, has a great price for 8 isolators, and it can accept phono, RCA, and XLR input/outputs (which gives great flexibility without adapters). They also publish their specs, most don't. If you don't use a buffered or adjustable output to drive these isolators you will notice a drop in volume and apparently this is normal for all isolators. Have essentially no tone change with these and that was my biggest concern and the ground loop hum problem is solved.
