Heil HPS-5 Powered Speaker, The Heil Powered Speaker (HPS-5) is a two-way, powered speaker designed to be used with the Heil Parametric Receive Audio System Equilizer (PRAS EQ). The HPS-5 in combination with the PRAS EQ provides unmatched speech articulation and brings new dimensions to receive audio quality. 

The end result is a fantastic listening experience that relieves ear fatigue for operators. The HPS-5 has a low-distortion, highly efficient Class A 24-watt amplifier that drives a specially designed 5” low-frequency speaker mounted in a resonant sealed enclosure. A passive extended crossover drives a 2” high-frequency tweeter. 

The HPS-5 has two rear panel inputs: a balanced 600-ohm XLR input and an unbalanced 1/8” input. A single-level control adjusts the input signals for both inputs. There is also a balanced 600-ohm XLR output for combining two or more HPS-5 powered speakers. To use an extension/secondary speaker simply plug a 3-pin XLR out of the primary speaker to the XLR input of the extension speaker. In order to send audio from the primary speaker to the secondary speaker, the power must be on the primary speaker. The volume level of these speakers can be matched or independent. 

These will not function as stereo speakers. Included with the HPS-5 is a 12 volt, 2 amp power supply, and a 2 amp fuse is mounted on the rear panel.
