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.
Overview

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.

Operational Guidance
1. Phase tester - Test XLR cable
③Switch 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.
①Release screws & plug in 9V PP3
Alkaline batteries.
②Plug in XLR cable in each side.

2. Test speaker's phase by built-in MIC
③Switch 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.
②Plug female side of XLR connector into
transmitter and plug male side of XLR
connector into mixer or amplier.
⑤Aiming 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.
①Release screws & plug in 9V PP3
Alkaline batteries.

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.

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.
