Sound system installations for commercial applications, while requiring more and more versatility and high performance in terms of power and sound pressure, have increasingly limited space. HELVIA is well aware of these requirements and offers a line of single-zone mixer-amplifiers in standard ½ 19" rack unit format with power ratings ranging from 30W to 240W, capable of operating on both 70V/100V and low impedance lines up to 2 ohms with maximum stability (2-ohm operation is provided only for 120W and 240W models; for 30W and 60W models the minimum limit is 4 ohms). The HPMA series - where "P" stands for Pocket - integrates a mixer with 1 Combo Mic/Line input with 48V Phantom, a front AUX input with stereo mini-jack plus a rear stereo AUX RCA input, and a Multimedia Player with DAB+ and FM tuner, USB player and BT; the level of each input is independently adjustable from the front panel. The Class-D amplifier modules integrate digital processing with limiter, overheat protection, fan control, DC-offset and in-current to ensure operation at any high impedance audio level down to a minimum of 2 ohms* in complete safety. HPMA-Play series amplifiers can be rack mounted with the optional HPMA R1-Kit mounting kit.
