Radial JDI Duplex MK5 Stereo Direct Box

• passive stereo DI box
• versatile and easy to use
• excellent construction and a great sound
• special Jensen transformers, 100% insulated to prevent ground loops
• virtually zero phase and harmonic distortion
• exceptional signal processing
• sum - mono: converts the IN and THRU to left and right inputs to make a passive mix to mono
• -15dB pad switch: reduces the input sensitivity with -15dB to prevent distortion
• 180-degrees polarity switch: reverses the polarity at the XLR output
• ground lift switch, removes humming caused by ground loop currents
• XLR Sel: activates the +4dB XLR line input and dampens the 6.3mm, RCA and 3.5mm inputs
• audio circuit type: passive, based on transformers
• number of channels: 2 (stereo)
• frequency response: 20 Hz tot 20 kHz @ +/- 2 dB)
• dynamic range: 135 dB
• maximum input level: +20 dB at 1 kHz
• total harmonic distortion: 0.001%; 1 kHz/+4 dBu at 600 ohms
• phase deviation: -1° at 20 Hz; 0.5° at 150 Hz; 600-ohm load
• input impedance (unbalanced): 140 kOhms PAD off; 10 kOhms PAD on
• input impedance (balanced): 10 kOhms
• output impedance (balanced MXLR): 600 ohms
• shielding: Dual Faraday, mu-metal can
• input PAD: -15 dB (only 6.3mm jack and RCA)
• Sum Mono: Resistive summing mixer
• 180-degree polarity reverse: reverses pin 2 and 3 for the XLR outputs
• ground lift: disconnects pin 1 for the XLR outputs
• XLR configuration: AES standard (pin 2 = hot)
• rugged metal housing prevents circuit board from warping
• unique book-end design prevents damage to the buttons
• whole bottom is fitted with insulating anti-slip layer
• power supply: passive, no power required
• conditions: for use in dry conditions between 5 and 40-degree Celsius only
• colour: green (powder coating)
• dimensions: 160 x 48 x 127 mm (6.3 x 1.9 x 5 inches)
• weight: 1 kg (2.2 lbs)

Inputs:

• stereo RCA per channel
• 3.5mm TRS mini jack for line-level devices such as laptops and tablets
• +4dB XLR female (balanced) per channel
• 6.3mm TS jack per channel for instruments and line-level source devices such as keyboards and drum computers

Outputs:

• XLR male (balanced) per channel, 600 ohms for a hum-free signal up to 300 metres
• 6.3mm TS THRU, for an amplifier or monitor
