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.

Gold Line DSP30, the one-stop digital analyser. A portable, real-time 1/3-octave spectrum analyser, with built-in multi-segment display and 60 internal memories. Can be expanded to provide up to 1/12-octave analysis, while optional software packages extend its functionality to include Noise Criteria, Reverberation Time, Dosimeter and Speech Intelligibility measurements.

This is a packaged product consisting of:

• Gold Line DSP 30 digital portable 1/3 octave real time analyser with Windows software
• TEF04 calibrated microphone
• PN3B gated pink noise source
• DSP30 OPT RT60 reverberation measurement mode
• DSP30 OPT DAS distortion analysis
• DSP30 OPT STA loudspeaker timing analysis
• Hardcase

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

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

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.

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.

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.

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.
