The BRIDGE4A 19" 4-Channel Passive DI Box from Palmer is a studio-quality DI box in 19" rack format with upscale transformers that handle high levels without distorting or changing the sound characteristics of your content.
Each channel is equipped with a 1/4" TS input, a Thru output (for sending the input signals to an amplifier or other external destination), and two transformer-balanced front and rear panel-based XLR outputs. The 10:1 transformation ratio ensures optimum impedance and level matching for connected instrument signals from guitar, bass, keyboard, or synthesizer to be sent to a balanced microphone input. Thanks to a switchable 30 dB pre-attenuation, the unit can receive extremely high input levels. Galvanic isolation strips ground-loop hum, rendering a pure, clear, and ultralow noise signal. To add to the versatility of the unit, audio can also be output via Cat 5e (AES72), which vastly reduces cable management and setup time.
