Radial Engineering Pro-ISO +4/-10 dB Stereo Line Isolator NEW! AUTHORIZED DEALER!!!The Pro-ISO +4/-10 dB Stereo Line Isolator from Radial Engineering is a stereo line isolator designed to convert a professional +4 dB line-level balanced signal to an unbalanced -10 dB consumer-level device. This enables you to take the balanced output of a mixer and feed a consumer-level recorder or audio input on a computer.The Pro-ISO employs a transformer that focuses the energy in the voice range making it a suitable choice for sermons, news gatherings, and spoken voice.The passive design begins with 100% discrete components throughout. A set-and-forget level control lets you attenuate the input signal to prevent it from overloading the destination device. Output connections include a stereo pair of 1/4" connectors, a set of RCAs and a mini 3.5mm (1/8") for interfacing to a mini recorder or laptop computer. Transformer isolation helps eliminate hum and buzz caused by ground loops while eliminating stray DC currents from flowing.Utilizing Radial's bookend construction, the Pro-ISO has 14-gauge steel construction throughout. This creates a protective zone around the connectors and controls for added durability. The steel construction also assists by shielding the transformers from outside magnetic fields.Converts balanced line level signals to unbalancedStereo signal path with set & forget level controlTransformer isolated to eliminate hum & buzzCircuit TypePassive, transformer basedNumber of ChannelsStereo (dual mono)Frequency Response20 Hz to 18 kHz (+0 dB/ -3 dB)Dynamic Range130 dBMaximum Input+20 dBu @ 1 kHz / 1% THD+NTHD + Noise0.005% @ 1 kHzDeviationPhase: 1.5° @ 100 Hz; 3° @ 20 HzCMRR-76 dBInput Impedance1.3 kΩ, unbalancedOutput Impedance1.9 kΩ, balancedTransformerRadial transformerGround LiftDisconnects XLR pin-1 at XLR inputXLR ConfigurationAES standard (pin-2 hot)ConnectorsBalanced XLR-F in; 1/4", RCA and 3.5 mm TRS unbalanced outputsConstruction14-gauge steel chassisFinishBaked enamelPowerPassive, no power requiredDimensions (L x W x D)3.3 x 5.0 x 2.0" (83.8 x 127.0 x 50.8 mm)Weight24.8 oz (703.1 g)
