Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

This activates a shelving filter to reduce the low-frequency output by 2 dB to compensate for the half-space placement. · If you place the monitors into the corners of your room (quarter space [3A]), the low-frequency output approximately doubles from what it is in half space. Set the ACOUSTIC SPACE switch to the "A" position to reduce the low-frequency output by 4 dB to compensate for the quarter-space placement. · If you use the HR824 MK2s free-standing, away from walls and corners (whole space [3C]), set the ACOUSTIC SPACE switch to the "C" position (NORMAL). · The HR824 MK2s can be used with a home receiver even if the receiver lacks a preamp output by using a speaker-level to line-level signal attenuator.
