The SPT.LIGHT phase tester consists of two units: SPT2t transmitter and SPT2r receiver. The SPT2t transmits a positive-going pulse via a speaker, or a XLR balanced connector. The SPT2t speaker is placed near a microphone, which may be connected to an audio system. When testing a microphone it is very important that the mic face the SPT2t speaker directly at 90-degree angle. Further more, SPT2t features a LED work light, and SPT2r features a green laser pointer. For more details about the UNiKA SPT Series, please contact UNiKA Professional Audio at +886 2 2793-3017.

SPT-3rt is the best tools of UNiKA Stage Series. This tool is suitable for any speaker manufacturer, touring and fixed installation applications. It can be used for testing phase either speaker or balance cable. An external microphone input socket can be connected external dynamic microphone to test the speakers that have been hung up. By using neodymium magnet to combine transmitter and receiver units for easy carrying.
The DI-USB is a high-resolution stereo digital audio converter (DAC) and direct box that is designed to connect to any computer system to seamlessly transfer digital audio to analog. A professional Hi-Z direct input is also equipped, this is most commonly used with guitar pickups or keyboards, it also can be fed either from a linelevel output from the head (pad set to -20dB) or from the amplifier power output. A stereo pair of balanced XLR audio outputs with adjustable level control then feeds the signal to a microphone preamplifier, PA system, mixing console or even a powered speaker! Made for plug and play simplicity, the DI-USB will automatically be listed as an available sound card in the audio settings in all popular operating systems,including Windows 7/8, Windows 10 and Mac OSX. Connection to a computer is accomplished through a standard USB type-B port. Digital-to-analog conversion can be monitored on headphones through the 3.5mm analog output jack to check signal quality and level before connecting to a sound system. Two isolated output transformers are equipped to eliminate any hum or buzz caused by ground loops. To further reduce susceptibility to noise, this is augmented with a ground lift switch that lifts pin-1 on both XLR jacks.
PRO 3SP is a passive one-input and three-output isolated signal splitter without the need to install batteries or provide phantom power. PRO 3SP has a pair of built-in UNiKA-PROTM EI9AE3R3 1.25:1 isolation transformers, which has a special copper foil layer and a dedicated ground layer, which allows this device to restore high signal/noise ratio and dynamic sound, and can avoid unnecessary Leakage caused by radio frequency interference, ground interference and potential difference. PRO 3SP is particularly suitable for recording studios, live performances and fixed installation projects. PRO 3SP’s input uses XLR balanced sockets, suitable for inputting LINE signals. The XLR balanced sockets output by MONITOR are parallel and straight through without isolation transformers; CH-1/CH-2 output channels each have independent UNiKA-PRO isolation transformer and shared GND/LIFT switche for easy connection to remote or different power sources at the end of the equipment to eliminate the leakage and noise caused by the otential difference and the ground loop. WHEN TO USE PRO 3SP PRO 3SP’s CH-1/CH-2 are each equipped with independent EI9AE3R3 1.25:1 professional audio isolation transformer, which is a transformer that works in the audio range, also known as a low-frequency transformer. The frequency range is generally from 20 to 20000 Hz. It is mainly used for audio transmission between systems or devices. It can completely isolate the potential difference between two systems, avoid hum interference caused by ground loop problems, and prevent excessive potential difference from damaging the input level of the device. The safe transmission of signals is an essential product for long-distance transmission of analog audio systems. However, since it does not have an input amplifier circuit and attenuator, it can only transmit balanced signals through an isolation transformer or convert unbalanced signals into balanced signals for transmission, and does not have the function of increasing the level. If the input signal is of a high-impedance type, such as musical instruments or some players, it is recommended to use other DIs with input attenuators in the PRO series to transmit signals. These DIs also have a built-in EI9AE3R3 professional audio isolation transformer. The MONITOR output of PRO 3SP is paralleled from input without isolation transformer, usually used in near-end equipment, such as the connection between stage monitor console and active stage monitor speakers. In an analog system, PRO 3SP is equivalent to a signal distributor, which can distribute the signals on the stage to the stage monitor mixer, F.O.H. console and production console. Or in fixed installation applications, you can use it to distribute signals to different areas or rooms.
PRO BT5 is a passive DI box specially designed for playing back music from wireless mobile devices and built-in Bluetooth Ver.5.0 A2DP DUAL MODE module. The balanced output level will not be affected by the potentiometer. The output side is equipped with a TYPE-C USB terminal which requires a 5VDC power adaptor, power bank or USB port from computer to power the BT5 such as the power supply method of the general mobile device. BT-5 is excluding the TYPE-C cable and power adaptor. The built-in Bluetooth module has BR/EDR dual-mode control function, A2DP stereo playback mode and BLE energy-saving mode. And using Qualcomm chips and DA/DSP, audio converting and sampling rate are 16bit and 44.1KHz. The PRO BT5 has a pair of built-in UNiKA-PROTM EI9AE3R3 1.25:1 isolation transformers. The transformer has a special copper foil layer and a dedicated grounding layer, which can restore the high signal/noise ratio and dynamic sound of the device, and avoid unnecessary Leakage caused by radio frequency interference, grounding interference and potential difference. PRO BT5 is especially suitable for mobile phones, computers and any of Bluetooth music players. It converts wireless signals into low-impedance balanced signals, which is convenient for extending the wiring distance and blocking interference. PRO BT5 has built-in mini TRS headphone monitor output and monitor volume control, which can drive 16Ω~300Ω headphones to be allowing users to monitor the content that needs to be played in advance. Note: Since the device does not include charging identification IC, some of power bank with QC function may not be available or may stop supplying power halfway because the IC is not detected. On the other hand, the power bank with automatic stand by mode is not recommended.
PRO TWO is a passive dual-channel DI box. No need to install battery or provide phantom power to make it work. PRO TWO has a pair of built-in UNiKA-PROTM EI9AE3R3 1.25:1 isolation transformers, which has a special copper foil layer and a dedicated ground layer, which allows this device to restore high signal/noise ratio and dynamic sound, and can avoid unnecessary leakage caused by radio frequency interference, ground interference and potential difference. PRO TWO is particularly suitable for electronic musical instruments, recording studios and fixed installation projects that do not use mixers. It converts high-impedance signals into low-impedance balanced signals, which facilitates extending the wiring distance and blocking interference. The PRO TWO uses a pair of TRS socket on the input, and a pair of TRS through out are convenient for musician to pass the direct signal to the instrument amplifier. In addition, it is equipped with a 0/-20dB attenuation switch, which is suitable for various types of audio signals with high and low impedance. The output terminal is also equipped with a GND/LIFT button to quickly eliminate ground noise.
