- Passive Stereo DI with Isolation Transformer
- Lift Switch
- 15dB Pad
- Passive Mono Direct Box with Custom Transfmer Rugged I-beam Construction
- Inexpensive direct box with a fantastic footprint and the sound quality
- The IMP is an in-line transformer that converts a line or instrument level unbalanced signal to a low impedance mic level balanced signal
- Converts a line or instrument level unbalanced signal to a low impedance mic level balanced signal
- An ideal direct box for anyone requiring professional quality and durability in an economical package
- Uses Whirlwind's TRHL transformer that's riveted, not glued, to the chassis
- Connect your guitar or bass directly to your mixer without losing tone due to impedance mismatches, long cables and cycle hum
- Converts any unbalanced line-level signal to balanced mic-level output
- Provides impedance and signal matching for the direct connection of instruments to amplifiers and mixers
- Allows the use of long cables without losing high frequencies
- Thru/Out jack lets you send the unbalanced signal to an onstage amplifier while the balanced signal is routed to the mixer
- High-impedance 1/4" inputs with Thru outputs
- Balanced XLR outputs with ground lift
- Ultra-low noise and distortion
- -15dB pads ensures Distortion-Free performance when connecting to high-output sources
- Built-like-a-tank construction
- 【Dual-Mode Operation: DI + Line Isolator】: DI (Direct Injection) mode converts high-impedance instrument signals (guitar, bass, keyboard) to balanced XLR outputs for clean connection to mixers. LI (Line Isolator) mode eliminates ground loop hum when connecting line-level sources like audio interfaces, DJ mixers, or drum machines. Use DI for instruments, use LI for line-level equipment—switch instantly with one toggle.
- 【Passive Stereo Isolation & Ground Loop Elimination】: Dual-channel passive transformers provide clean signal transfer without batteries or phantom power. GND Lift switch breaks ground connections to eliminate annoying 60Hz hum and buzz. Perfect for complex setups with multiple devices sharing power—noise-free audio in any environment.
- 【-15dB PAD Switch for Signal Protection】: Active pickups, synthesizers, and hot line-level sources can overload your mixer's input. Integrated -15dB PAD attenuates incoming signals, preventing distortion and protecting downstream equipment. Essential for modern active instruments and high-output keyboards that would otherwise clip your signal chain.
- 【Flexible Routing: Stereo, Mono, or Summed】: INPUT accepts your instrument or line signal, THRU sends unaffected signal to your amp or monitor for stage monitoring. SUM/MONO switch combines stereo signals to mono for single-amplifier setups, or keeps stereo separation for full-range keyboard rigs and DJ setups. Dual XLR outputs feed your mixer or PA system.
- 【Universal Connectivity for Studio & Stage】: Perfect for guitars, basses, keyboards, synthesizers, DJ mixers, and drum machines. Connects unbalanced 1/4" outputs to balanced XLR inputs on mixers, PA systems, and recording interfaces. Rugged metal chassis withstands touring and live performance demands. Professional results for studio recording and live sound applications.
