Palmer Pinn River Series Active 2-Channel DI-Box

Palmer's Pinn River Series active DI box delivers transparent 2-channel signal conditioning for live DJ rigs and production workflows where instrument integrity matters. Its low-noise active circuitry maintains higher input impedance than passive designs, capturing uncoloured guitar, bass, keyboard and synth signals without treble or bass loss. The dual-channel architecture handles stereo sources or two instruments simultaneously, making it essential infrastructure for setups incorporating live performers, hybrid controllers, or multi-source mixing scenarios.

The balanced XLR outputs feature galvanically isolated transformers with independent Ground Lift switches per channel to eliminate ground loop hum that plagues long cable runs in club and festival environments. Dual THRU outputs transmit original instrument signal to amplifiers, while a summed stereo output conserves mixer channels. Signal path handles high-level synth and keyboard outputs without unwanted distortion, and the 30 dB pre-attenuation function enables looping between amplifier and speaker for capturing processed tone. Power input accepts 48V phantom power or universal 9–24V PSU, providing flexibility in mobile and permanent installations.

The sum output functionality proves especially practical in constrained mixing scenarios, where consolidating two discrete sources into a single channel preserves desk real estate for effects sends and additional inputs. Ground Lift switches eliminate hum without repatching, while the active architecture ensures magnetic pickups on electric guitars and basses retain their characteristic transient response and harmonic content throughout extended cable runs to front-of-house systems.
