• CT3 voltage and current tester: with 1 group of banana jack input and output, connected between amplifier and speaker to test the output voltage, current and power(P=UI), to detect that the actual output power of the amplifier is up to standard and the output of left and right channel is balanced or not.

• Strong adaptability for different amplifiers: compatible with digital amplifiers (Class A, Class D, Class T), AV amplifier, also for tube amplifier for tube readjustment. When tubes are used for long time or changing other tubes are, effectively avoid imbalance of left and right channels via CT3 testing.

• Designed with two 8ohm/20W resistors: support to test and monitor the output power of amplifier when the speakers are not connected, the pointer will also dynamically beat along with the real-time output, as a power VU meter to decorate your desktop.

• Large meter display and excellent design: dual large meter for each channel show the voltage and current clearly; metal case, more solid and with better shielding performance; with output load switcher, no need to plug speaker cables repeatedly.

Warm tips:

1. Build-in 2PCS 8Ω/20W resistors can be used for standard testing when speakers are not connected; 
2. If testing higher output power, please connect to speakers as load, the max power that can be tested is 60W@6.6Ω (load). 
3. 60W test power is measured at which both voltage and current meters reach their limits. The max measure power depends on speaker's load. For example, when the voltage is 12V while the current reaches 3A already, that means the max power measured is 36W.
