Specifications: HPA 2
The correlation between published specifications and performance is unreliable. A
list of numbers reveals virtually nothing. All technical measurements must be sub-
ject to qualitative as well as quantitative interpretation. Measurements of the Pro-
ceed amplifier yield excellent results by any standards. However, only those speci-
fications that apply to its actual operation are included here. All specifications are
subject to change at any time, in order to improve the product.
