User manual ROLLS PT102

[. . . ] The PT102 consists of two units, a transmitter and receiver. The PT102 transmitter creates a pulse that is sent through an audio system. The receiver then picks up the signal at various intervals in the system, and indicates whether or not the system is in or out of phase. The PT102t transmits a positive-going pulse via a speaker, or a 1/4" unbalanced jack. [. . . ] Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. IN NO EVENT SHALL WE BE LIABLE FOR ANY SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES FOR BREACH OF THIS OR ANY OTHER WARRANTY, EXPRESSED OR IMPLIED, WHATSOEVER. Some states do not allow the exclusion or limitation of special, incidental or consequential damages so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. 1 6 SCHEMATIC Transmitter POWER: Push switch - turns the PT102t on and off. LEVEL: Adjusts the amount of test pulse level sent out the OUTPUT jack. OUTPUT: 1/4" unbalanced jack for connection to the input of the device to be tested. PWR: LED indicating power is properly connected to the PT102t and the POWER switch is in the on position. Speaker: (Not labeled) Creates an audible pulse. To be placed in front of a microphone which may then be tested, or connected to a system being tested. NOTE: The speaker is always ticking when the transmitter is on. BATTERY: Removable door, 9 Volt battery clip. Receiver LINE IN:1/4" unbalanced jack for connection to line level devices carrying the pulse signal from the transmitter and system being tested. MIC: Small condenser microphone on the top of the PT102r. Picks up the audio pulse from a speaker. IN PHASE: Green LED indicating positive-going or inphase signals. OUT OF PHASE: Red LED indicating negative-going or out of phase signals. BATTERY: Removable door, 9 Volt battery clip. POWER SWITCH: When switched to the ON position, turns on the PT102r. PWR: LED indicating that the PT102r is on. DESCRIPTION LINE IN IN PHASE MIC + OUT OF PHASE - BATTERY PHASE TESTER RECEIVER PT102r ON PWR INPUT LEVEL 5 2 OPERATION The PT102 will check the phase of any audio signal source. There are, however, some considerations that must be observed. [. . . ] If the microphone is a condenser type, the mic must first be powered by either its own internal battery, or by a phantom power adapter. Rolls PB23, PB223, or PB224 are all correctly phased phantom power adapters, and may be used to power condenser microphones. The output of the condenser mic or phantom power adapter may be plugged into the PT102r receiver using the unbalanced cable mentioned above, and the mic is tested the same way. AUDIO SYSTEM PHASE To check the phase integrity of your audio system, connect the 1/4" OUTPUT of the PT102t to the input of the system to be checked. [. . . ]
