70v-capable models feature Transformer Saturation Protection (TSP) that monitors the current demands of the transformer and can protect against overload and distortion. All models are equipped with extremely quiet fans providing front-to-rear air circulation, guaranteeing trouble-free operation even in smaller power amplifier rack systems.

Anyway, in most cases the permanent connection of a computer bears benefits, like displaying detailed status reports or the printing of protocols. It also offers the possibility for remote diagnosis and remote maintenance via modem.

In addition to the spacing pattern, the designer must choose between three density types, designated respectively as edge-to-edge, minimum overlap and center-to-center (see Figure 1). The greater the overlap, the more uniform the coverage — and the higher the cost. Budgetary ElectroVoice/Dynacord BGM Guide Page 17... -

The actual listening-plane coverage depends on the polar plot of each speaker. On average, the coverage of the listening plane from a speaker with a 140° polar coverage is usually between 90° and 110° . ElectroVoice/Dynacord BGM Guide Page 18... -

— at a significant savings — by using specially designed 4-inch elements. Characterized by somewhat smoother frequency response and less susceptibility to feedback than 8-inch elements, 4-inch units are also generally less expensive and offer a real advantage in reduced directivity.
