General Information

Hamlet has designed a unique digital and analog equiped signal generator, the Protean Index. Designed for the professional broadcast industr, it is a multi-functional SD, Composite, video and audio hand-held portable generator.

With 16 x SD; 16 x composite video; group selectable and identable embedded, AES/EBU and analog audio, test signals its ideal for mixed signal path testing. In addition to industry standard video signals it provides a moving pattern MPEG signal, path continuity check test signal and circle and alphanumeric text overlays, that can be set to move if required.

They are dual standard, 625/525 and PAL/NTSC. The units produces up to four channels of embedded audio, AES/EBU and analog reference tone or silence which enhances the flexibility of the generator. The Protean has full broadcast CCIR601 (SMPTE259M)

The product is designed for television broadcast engineers working in maintenance, installation, field operations, outside broadcasts, single camera shoots and even editing suites, anywhere digital and analog signals are required.

We hope some of the frequently asked question we  have had will provide assistance, if not please contact us directly or go through your supplier.

Q How do I get the scrolling text?
A Power down the instrument, hold the 100% bar button down and now power on, the text willl now be scrolling. This feature disables the selection of any other button i.e. you cannot change signal, to do so would mean turning the scrolling text off (power down then power on) select new signal then switch scrolling text on
Q I cannot use the CRC button?
A The CRC function is only available if all 'shift' functions are turned off i.e. ID and MPEG pattern.

Q I can only get mono analogue audio?
A The Protean series only gives out as a signal signal channel analogue audio, all other formats have stereo capability.

Q Why can I not use the bottom corner signals?
A When the text ID is turned on i.e. the black line near the top of the screen with characters on the bottom corner buttons are used to move the text along the line. To use these signals first turn the text ID off, select signal, then turn text ID on

Q How long will the internal batteries last?
A About 1 hour if using both analog and digital outputs. about 2 hours by turning the analog output off.
