How could your toolkit be without one of these? An essential item for any sound contractor involved with testing distributed loudspeaker systems and components, especially 70V and 100V-line installations. The Gold Line ZM1P also calculates a system’s wattage, and includes a tone generator. Totally useful, and completely indispensable.

Based on Gold Line's popular ZM1P Impedance Meter, an essential part of a contractor's toolkit, the ZM2N which is built into an extremely tough, fibreglass- reinforced, watertight, ABS carry case, is specifically designed for industrial environments, and incorporates a tone generator with a very high output level, making it particularly suited for testing 70V and 100V-line installations, in areas with high ambient noise levels

Pink Noise Generator providing continuous pink noise. Whenever the GLPN is connected to a system with Phantom Power, the LED on the back will light. If it does not light then phantom power is not present.

Keep one in your toolkit, keep one in your pocket. The GL1K includes a 1kHz test tone, and a phantom power LED indicator, for checking mixers, cables, stage-boxes and wall-boxes. Simple, practical and inexpensive.

This 14 function sine wave generator with a Phantom Power Indicator is a handy and cost effective tool. Rugged and pocket-sized, it belongs in every toolbox. The compact design features a Microphone Level Output with 14 functions activated by a single push button. Packaged in a Standard Neutrik XLR connector, the GL14 is easy to carry and easy to use. Its multiple functions will help with the analysis and calibration of sound systems and will facilitate trouble shooting. The internal amplifier in the GL14 utilises phantom power to generate the tones

Designed to ease and speed up the task of checking loudspeaker polarity, the Gold Line APT2 ensures consistency across multi-speaker installations. It allows an entire system to be checked in seconds, including individual drivers and complete cabinets, as well as equalizers, amplifiers and crossovers. The unit’s performance is unimpaired by passive crossovers, or by signal waveform distortions produced by the device under test, and is supplied complete with a

Portable and easy to operate, the self-contained DSP2B is one of the few internationally accredited and self-contained devices capable of making objective measurements of intelligibility in the world-renowned STI format. Essential for regulatory compliance testing.
