Reverse DI Box
Users frequently attempt to connect a DI box in reverse in order to feed a balanced signal into an unbalanced input. Because of mismatching, however, this leads to unsatisfactory results. With the PDIR01 (DI-REVERSE), we offer a box that provides a perfect technical solution to the problem without using adapters.

| Standard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High-impedance input; higher output level than with a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out -4 dB). Maximum output impedance with phantom power operation +10 dB. Output: transformer balanced. The special "floating ground" circuitry enables ground lift even during phantom power operation. Metal case 110 x 73 x 42 mm. |
The Stewart ADB-1 is a single channel active direct box that allows an unbalanced source to
directly feed a balanced input. Musical instruments, tape recorders, VCRs and sound projectors
can be run "direct" to the mixing console, avoiding unnecessary degradation of sound quality.
The ADB-1 operates on either phantom power or a 9-volt battery.
FEATURES:
Flat response
Low distortion
Low noise
Wide dynamic range
No transformer
RF protection on input and output
Switchable ground isolation
Flush mounted slide switches |

| Behringer DI-600P High-Performance Passive Direct Injection Box
Introducing the Ultra-Compact DI-Boxes from BEHRINGER
There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that?ll corrupt the signal.
The DI600P lets you connect instruments or amplifier outputs of up to 3,000 Watts. It converts any unbalanced signal to a balanced signal and eliminates unwanted noise. With its high-performance transformer, it also allows you to use very long cables without the loss of high frequencies.
This is the sort of medicine that?ll cure headaches in your studio or on stage.
It often happens that you want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. The direct connection between audio equipment can quickly turn out to be a real challenge: technical problems crop up that can affect the signal.
Hook Your Guitar or Amp Up to the PA
Be ready for your next gig with the Behringer Ultra-DI DI600P direct box. Designed to send instrument or amplifier signals to the main mixing board, the DI600P is a high-performance passive DI is a useful tool in any gig rig or studio. Dual 1/4" TS jacks are wired in parallel let you plug your instrument into one and use the other as an output to your amp. The balanced XLR mic-level output feeds your mixer a clean and super-flat signal that is true to the source. Sweetwater knows that grounding issues and hum can be a problem at live gigs. The DI600P sports a ground lift switch to kill unwanted ground loops and hum. It also has a filter switch for optimal guitar tone and an instrument/amp switch with a 30dB input level drop. The Behringer Ultra-DI DI600P direct box is an extremely useful tool for any stage rig!
Behringer Ultra-DI DI600P Direct Box Features:
- Compact, high-performance passive direct box
- Jack input 1/4" TS in and parallel out
- Gold-plated XLR output / impedance balanced
- Super-flat frequency output for uncolored sound
- Switchable filter that optimizes the DI for guitars
- Instrument/Amp switch lowers the input level 30dB for feeding amplifiers into the DI
- Instruments or amplifier outputs with up to 3,000 watts can be connected directly
- Offers impedance and signal matching of instruments to mixers
- Perfect for stage and studio use
- Ground lift switch eliminates typical ground loop problems
- Rugged metal case can take the rigors of the road

DOD AC 275 Active Direct Box with Switchable Ground Lift and Attenuator-2nd Hand- The AC 275 is an active, phantom powered direct box. Unlike a passive DI where the frequency response of the signal can be altered depending on the connected impedance, an active DI buffers the input signal with an amplifier. This assures that the sound source will reach the mixer balanced and noise-free. Housed in a cast alloy chassis, the AC 275 supplies two, high impedance, unbalanced 1/4" jacks and one low impedance balanced XLR jack. It operates with battery or phantom power.
