Each Year, 4½ Bonus Days With Test Chest

Murraypro celebrated 20 consecutive exhibition years at IBC's Amsterdam Expo with the release of a new version of their rack mounted Test Chest.

This 2U format mains powered unit streamlines the features of the battery portable and its Audio-Pod accessory to produce a highly integrated product, containing its own UPS, and optimised for tail board incorporation by System Integrators.

Visitors to the Murraypro stand have never failed to be impressed by the staggeringly fast one second "Seeing is Believing" speed of Test Chest's power up from cold. Several attendees commented that from their own experience, each rapid power up event would actually save around one minute of otherwise totally wasted time! In fact, we have long declared, that when compared against other testers, using Test Chest just six times a day, over the space of one year, a busy maintenance department would actually gain over 4½ EXTRA working days of eight hours – and for such a cost-effective unit that's a pretty impressive no-brainer bonus.

Tony, Murraypro's Demonstrator, has a panel with eight quite different sources available on the stand, each of which are positively identified using Test Chest's unique Which-Wire?, a very powerful, speedy and totally automatic 'hands-free' detection mode. When giving demonstrations he takes care to emphasise Test Chest's intuitive menu structure, which with coupled with its highly practical four hour battery endurance, offers another pretty spectacular bonus over competitive products.

Test Chest's newly introduced AES Eye mode, which is now included as a standard feature, was well received and was felt to be particularly valuable, specially when investigating infrastructure problems where the particularly fast rise time of the signal excursions often promote system ringing when used with XLRs and associated balanced AES cabling. The high stability of the Test Chest's locally regenerated AES clock is of significant value when visualising and investigating jitter problems.

As ever, live demonstrations of Test Chest's TDR function were given using the Murraypro demonstrator unit which, when at shows, is certain to generate an appreciative audience. It rapidly simulates a number of catastrophic cable faults and their distance down the cable, through to more subtle effects where the reflections from relatively minor imperfections can be clearly shown down a cable run on the unit's LCD screen, with return loss displayed in dB.

Murraypro's diminutive TV Eye unit was present in its new livery, and its impressive input equalisation capability was demonstrated recovering a signal that was actually buried in noise, as it had suffered very significant cable attenuation, to produce a perfect noise-free picture.
