CHAPTER 2: HMS LOUDSPEAKERS

12

CAUTION:

Continuous limiting indicates that a

safe, optimum level has been exceeded. If the

HMS loudspeakers in a cinema installation begin to
limit before reaching the desired SPL, consider adding
more units to the system.

Operating Temperature

The On/Status LED also turns solid yellow when the HMS
loudspeaker’s internal temperature reaches a certain level,
indicating the unit is reaching its maximum heat dissipation.
When the On/Status LED is yellow, a reduction in SPL is rec-
ommended. While the loudspeaker will continue to operate
while the LED is yellow, the limiter threshold is lowered (caus-
ing the output level to also be reduced) to prevent the loud-
speaker from overheating. When the loudspeaker’s internal
temperature returns to a normal level, the On/Status LED
returns to green and the limiter threshold returns to normal.

Amplifier Cooling

HMS loudspeakers rely solely on natural convection for cool-
ing from air flowing over their heat sinks. The efficient ampli-
fier and heat sink design keeps temperatures low, even when
units are operated at high ambient temperatures and driven
continuously at high output levels.

Clipping on Input (Red)

The On/Status turns red when the loudspeaker’s input stage
clips, causing the amplifier to overload. When the On/Status
LED is red, the source level should be reduced to avoid dis-
tortion and to avoid overloading the amplifier.

CAUTION:

If the On/Status LED turns solid red

and the loudspeaker continues to output audio,

though at reduced levels, the loudspeaker’s voltage
may have dropped below 25 V DC. When these con-
ditions are encountered, operation of the loudspeaker
should cease and its power supply and cabling should
be verified.

PAD SWITCH (HMS-10 ONLY)

The HMS-10 user panel includes a Pad switch that, when
enabled, reduces the loudspeaker’s internal gain by 7.5 dB,
thereby lowering the loudspeaker’s noise floor. This reduces
noise generated from audio sources upstream from the loud-
speaker and is especially useful for close-proximity listening.

NOTE:

When the Pad switch is enabled (set to

Pad), to achieve the linear peak SPL for the

loudspeaker, the gain for the processor driving the
loudspeaker must be increased by 7.5 dB.
