Using the Meyer PS-1 AC adapter is the simplest way to assures true point-source performance without the off- power a pair of HM-1s, or a single HM-1 with a sub- axis cancellation effects that normally plague dual- woofer. The AC adapter can be purchased through Meyer concentric designs.

35 VDC. At 35 V, the maximum current draw is 25% lower than the values stated in the preceding tables. NOTE: If the HM-1 will not be driven at continuous limiting, a power supply that satisfies the moderate specifications i l l for voltage and current can be used safely without risk of sonic degradation or interruption.
Each plug is keyed such that it A single HM-1 attached to a 100 ft 18 AWG cable (1.27 Ω can be inserted only into the correct location. For example, total) produces a 6.4 VDC loss at the speaker (41.6 V)
HM-1 is exposed. The addition of one subwoofer increases the maximum SPL of a single HM-1 by 4 dB (without sub: 116 dB SPL; with sub: 120 dB SPL). The HM-1 Subwoofer has the...
75°C. Protection and Limiting The front of the HM-1 has two LEDs that indicate power and limiter activity. The right LED is green when power is applied. This LED turns red if thermal limiting occurs (described in the section Cooling and Fan Installation ) until the temperature decreases to 75°C.
