ZM1P Impedance Meter 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 ZM1P also calculates a system’s wattage, and includes a tone generator. Totally useful, and completely indispensable. More information...

TS2 Audio Test Set A general-purpose test set, with tone generator and level meter, for conducting dBu, frequency and impedance measurements across the full audio bandwidth. More information...

APT2 Polarity and Phase Tester Designed to ease and speed up the task of checking loudspeaker polarity, the 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 complementary pulse tone generator.

TK5.1 Surround Sound Alignment Multiple-speaker surround systems are becoming increasingly prevalent in presentation and entertainment applications. The TK5.1 provides a set of test tones on CD, for aligning the loudspeakers in 5.1 surround systems, in small theatres, AV and corporate entertainment facilities. More than 80 test signals, presented in a logical progression, enable a system to be calibrated quickly, while a comprehensive tutorial guides the installer through the process of optimising the system.

GL1K Microphone Input Tester 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.

GL60 Reverb Meter A simple and easy to operate RT60 meter. Designed for use in conjunction with the PN3A gated noise generator, the RT60 offers switchable sensitivity, and enables reverberation time to be measured at six selectable frequencies, displaying the results on the integral LCD screen.

PN3A Gated Noise Generator An extremely useful pink noise generator, selectable for continuous or gated output, designed for reverberation measurements and loudspeaker testing, and particularly for adjusting delay alignments across multiple-speaker installations. Includes a dedicated noise-burst function for RT60 measurements, and an STA setting for speaker time-alignments, plus a continuously variable gate time.

SPL Sign A highly practical product that combines the functionality of a SPL meter with a programmable message display built into a tough, extruded-aluminium case. Equally useful for entertainment venues and industrial environments, the SPL Sign provides safety officers, technicians and sound engineers with a simple means of keeping a constant watch on levels.

SPL 120 Meter The Gold Line SPL 120 hand-held sound pressure level meter, is a compact unit that can be powered from batteries or an external dc supply. A front-panel selector permits switching between A- or C-weighting, or a flat response. The SPL 120 can measure up to 123dB and utilises class 2 filters to the ANSI S1.4 standard. The unit features a built-in omni- directional electret condenser microphone, and has the added convenience of a high-impedance line-level input. More information...

ZM2 Industrial Impedance Meter Based on Gold Line's popular ZM1P Impedance Meter, an essential part of a contractor's toolkit, the ZM2 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. More information...

CBM1 Boundary Microphone The CBM1 offers all the benefits of boundary-type microphones - receipt of direct and reflected paths simultaneously and in phase, plus better ambient pickup - and utilises an omni-directional flat response electret microphone. Built into a small, strong aluminium case and powered by an internal battery, the CBM1 also has a phantom power facility, and can be used successfully in very high SPLs to provide low-distortion results at up to 150dB.
