Boost Function

Passive Direct Box: This pair of DI boxes enables the connection of any unbalanced audio signal, for example an electric instrument or keyboard. It also works from an amp speaker output to any unbalanced input such as a mixer.

Attenuator Switch Box: The parallel output allows simultaneous connection to two separate inputs, like an amplifier and mixer. The attenuator switches from 0db, -20db and -40 db.

Direct Box: This direct box will translate high impedance instrument outputs into low impedance balanced signals. or balanced low impedance signals into unbalanced outputs.

Fully Active Design

Phantom Voltage or 9v Battery Powered

Converts High-Impedance Balanced / Unbalanced Inputs Into 600 ohm Balanced Outputs

Active 48-Volt phantom powered direct box -15dB pad 180 degree polarity reverse Merge function to mix 2 signals to mono 80Hz high-pass rumble filter Ground lift Welded I-beam construction Minimal power draw with high rail voltage Will not choke when driven hard Low intermodulation distortion

The J48 is capable of peak transients to 9 volts without choking

The result is lower harmonic distortion, half the inter-modulation distortion and significantly improved dynamics over other DIs

Features: Rockville RDI5 Passive DI Box - Converts Guitar/Instrument or other Signal to Balanced Line Level. Switchable input attenuation. 0dB for electric guitar and bass pickups. -20dB for line level signals, such as keyboards and cd players. -40dB for speaker feeds. Input Connectors: 1/4" TRS Jack connectors. Output Connector: XLR Connector. 50K ohm instrument input. 50K ohm parallel link jack.

Matches the signal level and impedance with unity gain, with no adverse effects on the source signal. 600 Ohm XLR output jack - enables you to send a balanced signal to a mixer. We use a transformer that is 2-3 times larger than most other ones on the market to give you true 600 ohm output. The 50K ohm parallel link jack output enables you to connect the output from the RDI5 directly to power amplifiers without a separate pre-amplifier.
