The Radial ProAV1 is a single channel passive direct box designed specifi cally for the audio video professional where ‘Swiss Army knife’ connectivity is required to meet on-the-fl y demands of AV rentals and installations.
Input connectivity includes stereo RCA, 1/4” and 3.5mm (1/8”) for high-impedance instrument and -10dB consumer line-level devices. All inputs may be used as thru-puts and are auto merged to mono to reduce cable infrastructure and audio channel requirements. A +4dB XLR input is also provided to interface professional balanced line-level signals. The output is standard 600 Ohm mic-level for direct interconnect to mixing console mic inputs. These features make the ProAV1 an ideal interface for portable computers, CD players, iPods and other sound sources that must interface to PA systems alongside microphone lines.
Features
• Great-sounding, fl exible passive DI
• High performance custom-wound transformer
• XLR, 1/4”, RCA and 3.5mm inputs
• Built-in stereo to mono merge function
• -15dB PAD for wide range of input levels
• Transformer isolation eliminates ground loops
Applications
• Converts hi-Z consumer to low-Z mic-level
• Connect a stereo source to a mono channel
• Unbalanced audio from CDs, laptop, VCRs
• Balanced +4dB audio sources (ProAV1 only)
Cool stuff
• Like a Swiss Army knife for A/V systems
• Completely passive, no power needed
• Ultra-tough 14 gauge steel enclosure
• 3 year transferable warranty
ProAV2 features two independent channels with two Radial transformers for 100% discrete dual mono operation.
1/4” INPUT and THRU-PUT standard connection for bass, guitar and keyboard.
RCA -10dB stereo input can be used with CD players, tape decks, VCRs, etc. A second set of RCA jacks can be used as a thru-put.
-15 dB PAD reduces input level from high output devices like CD players and headphone outputs.
3.5mm TRS -10dB stereo input connects PC sound cards and headphone jacks.
GROUND LIFT disconnects the ground path at the XLR output.
BOOK-END DESIGN creates a protective zone around the jacks and switches.
XLR OUTPUT balanced 600Ω mic­level to drive long cables run through snakes & studio patch bays.
XLR LINE INPUT +4dB connection for professional audio sources with side mounted defeat switch.
RADIAL TRANSFORMERS for distor­tion-free signal transfer and 100% isolation from ground loop hum.
MU-METAL SHIELD for protection against radio frequency and electro­magnet interference.
14-GAUGE STEEL welded I-beam enclosure makes it impossible to torque the PC board. Eliminates cold solder joints.
ProAV1
Use just like a straight ahead DI for mono instruments like guitar and bass. Parallel thru-put connects on-stage amp.
