Intelligent Ac Power Supply - Meyer Sound LINA Operating Instructions Manual

CHAPTER 2: POWER REQUIREMENTS
Use the information in Table 3 to select the appropriate
cable gauge and circuit breaker ratings for the system's
operating voltage.

The minimum electrical service amperage required by a
loudspeaker system is the sum of the maximum long-term
continuous current for all loudspeakers. An additional
30 percent above the combined Maximum Long-Term Con-
tinuous amperages is recommended to prevent peak volt-
age drops at the service entry.
NOTE: For best performance, the AC cable volt-
age drop should not exceed 10 V (10 percent at
115 V and 5 percent at 230 V). This approach ensures
that the AC voltage variations from the service entry—
or peak voltage drops due to longer cable runs—do not
cause the amplifier to cycle on and off.

INTELLIGENT AC POWER SUPPLY

LINA's Intelligent AC™ power supply automatically selects
the correct operating voltage (allowing the loudspeaker to
be used internationally without manually setting voltage
switches), eliminates high inrush currents with soft-start
power up, suppresses high-voltage transients up to several
kilovolts, filters common mode and differential mode radio
frequencies (EMI), and sustains operation temporarily during
low-voltage periods.

Powering on LINA
When powering on LINA, the following startup events take
place over several seconds.
1. Audio output is muted.
100 V AC
2. Voltage is detected and the power supply mode is auto-
0.29 A rms
matically adjusted as necessary.
2.8 A rms
3. The power supply ramps up.
4.5 A rms 4. On the user panel, the Active/Status LED flashes multiple
colors successively.
9.2 A peak
5. The Active/Status LED turns solid green, indicating the
loudspeaker is unmuted and ready to output audio.
CAUTION:
!
turn solid green, or LINA does not output audio
after 10 seconds, remove AC power immediately and
verify that the voltage is within the required range. If
the problem persists, contact Meyer Sound Technical
Support.
