STAGE SERIES PHASE TESTER SPT-3rt User Manual Overview Features Functions Instruction Operation Guidance Notes Specification www.unikapro.
Overview 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. 1 www.unikapro.
Features 1. Detect the phase accuracy in any audio system, prevent the musical signal from cancellation due to the opposite phase. 2. Detect the XLR signal cable to prevent it from contact fail, brokerage or opposite connection. 3. Built-in external microphone input socket in order to use for the harder environment such as the hanging speaker cluster. 4. Testable range from 10 cm to 3 meters. Some ideal environment can be tested far away from the axis of speaker for 7 meters. www.unikapro.
Functions Instruction SPT-3t Transmitter ① ① Buzzer to generate pulse tone. ② Neodymium magnet to combine SPT-3r receiver. ③ HOT PIN selector, select test pin of XLR cable either ② ⑧ ⑨ ③ ④ pin-2 or pin-3. ④ Linear pot to tune pulse tone level. ⑤ Release screw to open battery cabinet. Recommend to use 9V PP3 Alkaline battery. ⑥ Neodymium magnet to combine SPT-3r receiver. ⑦ Male XLR connector to connect balance cable to send pulse tone to mixer. ⑧ Power and pulse tone indicator. ⑤ ⑨ Power switch.
Functions Instruction SPT-3r Receiver ① ② ① Omni direction microphone. ② Red color out phase indicator. ③ Green color in phase indicator. ⑨ ⑩ ⑪ ④ Input selector, select test sources and applications ③ ④ ⑤ from built-in Mic/Cable test/EXT MIC etc. ⑤ HOT PIN selector, select test pin of XLR cable either pin-2 or pin-3. ⑥ Release screw to open battery cabinet. Recommend to use 9V PP3 Alkaline battery. ⑦ Neodymium magnet to combine SPT-3t transmitter.
Operational Guidance 1. Phase tester - Test XLR cable ③ Switch on the power and tune level then you will hear the click tone. ④ Shift receiver’s INPUT switch into LINE position. Shift the same pin number at both side then the green IN led will be shined if the both pins are proper soldering in symmetrically. If the red OUT led is shining then meaning the pin 2/3 are reversed from the other side. ① Release screws & plug in 9V PP3 Alkaline batteries. ② Plug in XLR cable in each side. 5 www.unikapro.
Operational Guidance 2. Test speaker's phase by built-in MIC ⑤ Aiming receiver’s built-in mic to axis position of speaker from 1 meter or more distance. If the green IN led is shined then the phase of speaker is proper. If the red OUT led is shined then the phase of speaker is reversed. ③ Switch on the power and tune level then you will hear the click tone. ④ Shift the receiver’s input switch into MIC position. And adjust transmitter’s LEVEL. You can hear click tone from speaker.
Operational Guidance 3. Test speaker's phase by EXT. MIC All procedures are same as Chapter-2 But connect ext. dynamic mic to be instead of built-in mic. And shift INPUT switch into EXT.MIC position. Note: Do not use condenser mic because receiver did not provide phantom power. 7 www.unikapro.
Notes 1. Avoid direct sun light and damp working environment. 2. The unit is designed to operate between 0°~55°C (32°~122°F) and in an atmosphere of relative humidity up to 80%. 3. Recommend to use 9V PP3 Alkaline battery. info@unikapro.com If you still need further clarification, please send email to us and we will do our very best to reply you in short order. www.unikapro.
