Audio Precision AG52
The AG52 analog hardware generator option for Audio Precision’s APx Series of audio analyzers can generate exceptionally clean square waves with a rise time better than 2 ms. The AG52 can also generate all popular DIM test signals to complement a corresponding new DIM distortion-measurement capability in the software, ideal for power amp test and measurement. Other benefits include a 2dB improvement in THD+N (to -110dB typical) and an increase in maximum output level from 21.21 Vrms to 26.66 Vrms (balanced). The AG52 is supported by APx’s 2-channel APx 520/521/525/526 models. Price: $1,000.

Designed for studio or live sound installations, TEFnet is a complete TEF 25 analyzer with five MUX inputs and an additional input for special applications. The system is used with a dedicated house computer. The consultant installs microphones in selected locations and sets the parameters for Pass/Fail evaluation. The software will prevent any unauthorized change made to the consultant’s specifications. The Pass/Fail evaluation is based on a TDS test sweep and automatic sequential activation of MUX microphones. The Pass/Fail evaluation test uses modified Sound Lab speaker test software. The TEFnet system will also include Sound Lab Modules to measure RTA and NLA.
