Quadra Thru, is a desktop 1-input 4-output active MIDI thru box for connecting multiple MIDI devices without the timing issues associated with standard daisy-chaining.
The device's active circuitry cleans up any skewing of MIDI data that has occurred at the input, ensuring reliable operation in setups that require daisy chaining and long cable runs. The unit is MIDI powered and requires no external power supply or batteries. An LED indicator lights up when powered and flashes when data is passed through it. The MultiVoltage Quadra Thru is compatible with both the original 5V and the new 3.3V MIDI specification.
