Whirlwind LBS - 1x2 Line Balancer and Splitter
Key Features
  • Converts Unbalanced Signals to Balanced
  • Transformer Isolation for Reduced Noise
  • Pass Through and Split Functions
  • Ground Lift Eliminates Hum and Buzz
The Whirlwind LBS is a versatile, ruggedly built in-line device that balances and isolates a single line level signal, or allows a line level signal to feed two destinations. Transformer balancing and isolation is available for one or both of the outputs. The balancing provides the necessary noise rejection when in use with equipment having unbalanced outputs, feeding equipment with balanced inputs.

The Whirlwind LBS is a versatile, ruggedly built in-line device that balances and isolates a single line level signal, or allows a line level signal to feed two destinations. Transformer balancing and isolation is available for one or both of the outputs. The balancing provides the necessary noise rejection when in use with equipment having unbalanced outputs, feeding equipment with balanced inputs.

The transformer isolation built into the LBS helps eliminate the unwanted hum and buzz caused by power line and grounding problems. In ISO mode, the signal is passed directly through to one output, and transformer-isolated to the second output. In SPLIT mode, the signal is transformer-isolated to both outputs, with a resulting 6dB drop in level at each output. The unit is equipped with a ground lift switch for each output.

Balncer/Splitter
The LBS includes an in-line balancer and splitter box with 1-in, 2-out configuration, dual ISO and SPLIT mode operation.
Built Tough
Rugged, all-metal construction gives years of service.
Quality Circuitry
Transformer balancing, transformer isolation, and a ground lift switch are provided for each output.
Extensive Connectivity
Standard, recessed XLR output connectors, XLR and 1/4" TRS input connectors make the LBS easy to use.

question

Can I use this device as a splitter to make a backup recording on a Zoom H6 for example?I mean, I have a shotgun mic. I split the signal in two, put it in two inputs of the recorder... I don't want to use a Y because I could lose a lot of gain on the two outputs. Or do you have other devices that can do this? Or a good mixer (I mean affordable 300-500) to to team with the H6 that can do this? I plan to use it with a Shotgun AND a Lavalier. So 2x2 outputs. Thanks! ;)
Asked by: Jonathan T.
This device is designed for line level signals only. Splitting a microphone signal is never a good practice as there will be signal loss and added noise. A mixer, not a splitter is the way to go. The Mackie Mix8 (B&H # MAMIX8) is an 8-channel compact mixer that features high quality components, a rugged metal chassis, and is designed for a variety of sound reinforcement applications. The mixer features two mic/line inputs with 48V phantom power, two stereo 1/4 line inputs, and stereo 1/4 aux send and return. It is capable of accommodating dynamic and condenser microphones, keyboards, DJ setups, portable music players, and more.Each of the two mic/line inputs is equipped with XLR and 1/4 connectors, a dedicated 3-band EQ, aux send, pan, level control and an LED overload indicator. The two stereo 1/4 line inputs each feature an aux send, 3-band EQ, level control, balance control and also have an LED overload indicator. <a href= http://bhpho.to/1sLQeDj target= _blank >http://bhpho.to/1sLQeDj</a>

question

Does this unit require external power? if so, how much and on what kind of connector?
Asked by: Benjamin
The Whirlwind Line Balancer/Splitter requires no external power and is designed to split a single line level input signal into two balanced line level outputs. A choice of two output configurations is provided: one direct output and one isolated output, or two isolated outputs. The Line Balancer/ Splitter uses Whirlwinds TRSP-600L transformer and has a frequency response of 20 to 20kHz, 1dB @ +2OdBm.On the Line Balancer/Splitter are two male XLR jacks, one female XLR jack, a 14 jack and three switches as outlined below:INPUTEither of the two input connectors, a female XLR jack or a 14 TRS jack (Tip = Pin 2 and Ring = Pin 3) can be used for connection from a line level source, balanced or unbalanced. Use only one input at a time.OUTPUTSThe male XLR output connectors can be configured in one of two ways. The ISOLATED OUT/SPLIT 1 is always transformer isolated and the DIRECT OUT/SPLIT 2 is either directly connected to the input or transformer isolated, depending on the position of the OUTPUT SELECT switch.OUTPUT SELECTThis push-button switch selects the output mode of the unit. In the out position, the DIRECT OUT/SPLIT 2 provides a direct output signal and the ISOLATED OUT/SPLIT 1 provides a balanced 600 isolated signal. In the in position (the center of the switch changes to orange) both output connectors provide a balanced 150 ?isolated signal that is attenuated by 6dB from the input.GND/LIFTSEach of these switches disconnects the ground between the inputs and the XLR outputs when set to the LIFT position. Grounds remain connected when set to the GND position.This product is warranted to be free of defects in materials or workmanship to the original purchaser for a period of 3 years from the date of purchase.
