    4 Power Supplies for Larger Systems If an installation includes more than 10 speakers, or requires several speakers to operate from a single 48 V line, a single, high-output power supply should be considered. The following sections provide current and voltage specifications for the HM-1S s power requirements. Current Ratings The wide dynamic ran ...

    5 audio interruption. In the third, and preferable case, supplies that feature voltage foldback allow brief periods of current-limit without audio interruption; for this reason, we recommend using such supplies. The HM-1S does not require tight voltage regulation and operates down to 35 V although peak SPL values are reduced. This operating voltage ...

    8 Subwoofer Performance V erification There are two methods of verifying that the phase relationship between the HM-1S and its subwoofer. One method is free field, the other is a ground plane measurement in half space. Free Field: Place the HM-1S directly above and coplanar to the subwoofer as pictured below: Place a calibrated measurement micropho ...

    16 Cooling and Fan Installation The HM-1S depends on natural convection to cool the heatsinks that absorb heat from the amplifiers and radiate the heat into the surrounding air space. Natural convection requires free air in back of, and underneath the HM-1S to allow air to flow up over the heatsinks. The HM-1S reaches an equilibrium temperature in ...
