Utilizing an OEP/Carnhill transformer made in the UK, mated with a simple "less is best" design approach, the Telefunken passive DI's provide superior vibe and character to best complement the natural tone and feel of your instrument.

The high quality audio transformer is just one of the premium design elements in the TD Series direct boxes. The PCBs are all 100% hand-assembled exclusively with through-hole components to provide a much more secure and reliable connection compared to common surface-mount technology. All circuit traces are gold-plated for maximum conductivity over the life of the product. High input impedance prevents the loading down of passive pickups. The frequency response of the circuit is ± 2dB from 10 Hz to 40 kHz, with extremely low distortion and self-noise figures.

The circuit is housed in an extremely durable extruded aluminum enclosure with recessed switches and connectors. This rugged construction is virtually indestructible, able to easily withstand the wear and tear of gigging. Each channel features two heavy duty metal toggle switches to engage a -15 dB pad and ground lift. The TD-2 unit features two independent DI channels with separate controls, giving you the ability to run two instruments through one footprint on stage or in the studio.

The Telefunken passive DI design is your new go-to reliable, high quality direct box. The simple and elegant design approach yields a harmonically rich low-end with a detailed and open high end that delivers a new standard in reliability and performance for direct boxes.

    Correctly targeted by Amazon's suggestion
    I didn't know my dogs were crackheads until they tried this. They absolutely loved them. Even my 16 year old RUNS to get them. Definitely 5+ stars.

    Tasty treat but better as a quick reward than a long chew
    I gave these to my German Shepherd and Lab as occasional treats. They were immediately interested and finished them quickly, which usually means they’re both appealing and easy to eat. These aren’t long-lasting chews—they’re more of a quick snack. For larger dogs especially, they won’t keep them occupied for very long. Compared to tougher chew options, these are better suited for training rewards or short treat sessions. I’d rate them 4 stars. Good flavor appeal, but not designed for extended chewing. Tip: Use them as a reward treat rather than something to keep your dog busy.

    Chicken and Peanut Butter - Two Great Tastes That Taste Great Together... to my Dog
    My dog is a fairly selective eater, but she loves chicken jerky and peanut butter, so I thought I'd give these a try. She took to them right away, and can finish one off in about 3 minutes. They have a distinct smell of peanut butter (despite peanut butter only being 3% of the composition). Each chicken jerky-wrapped peanut butter biscuit is about 4.5" long, and they arrive packaged in a resealable bag. Made in China; my bag was printed with a 'BEST BEFORE' date over a year from the date I received them. Note that these treats have been irradiated to kill harmful bacteria and parasites.
