RAAL-requisite TI-1 Amp Interface for True-Ribbon™ Headphones

Enter Toroidal Impedance Matching Transformers!

Transformers will convert the AC signal of high-voltage/low-current into low-voltage/high-current. Essentially, it is turning a high impedance into a low impedance (or vice versa), allowing for matching mismatched sources and loads. This is a transformer's typical duty in ribbon tweeters and tube amps, both of which RAAL-requisite have tons of experience in designing and building. The development took a while longer than hoped for, but ultimately in the end, RAAL-requisite have now developed a transformer-based amp to ribbon interface with 32 and 16 Ohm inputs. It operates with less than -100dB distortion, can transfer 6 watts of power, exhibits no ringing, goes far into the ultrasonic, is safe to plug in and out of a fully cranked amp, safe to drive with headphones unplugged, and grounds the static electricity of the headphones. Simply put… TI-1 safely transforms your headphone amp into a huge current ribbon driving monster!

Open-Baffle Compensation

For driving open-baffle SR1 headphones, we have provided left/right OB Compensation adapters in XLR (balanced) & RCA (single-ended) variants. Just plug them into either of your amp’s inputs (XLRs or RCAs) and plug your interconnect cable into the OB Compensation barrel. That way, whenever you select that input, you will correctly drive your SR1 True-Ribbon™ headphones.
