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

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

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.

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.

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

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.

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.

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.

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