Meyer-sound PSM-2 Bedienungsanleitung PDF herunterladen

The PSM-2 self-powered stage monitor contains

independent amplifier and control electronics for one

12” cone driver and one 4” diaphragm horn driver in a

compact enclosure. This integrated design eliminates

amplifier racks, improves durability and reliability,

and simplifies setup and installation.

The PSM-2 can be oriented such that the planes of the

cabinet face and the horizontal surface on which the

PSM-2 is placed form a 35°, 55°, or 90° angle. Its top-to-

bottom profile is 20.5” at 35°, and 19.5” at 55° (1” higher

than the Meyer UM-1). The high-Q horn provides uniform

coverage in both the horizontal and vertical planes.

The PSM-2 has the following acoustical specifications:

Frequency Response ±4 dB 50 Hz – 18 kHz

Max Peak SPL at 1 m 139 dB

Dynamic Range > 110 dB

Coverage –6 dB: 50° H x 50° V

–10 dB: 70° H x 70° V

The PSM-2 is phase-corrected through the crossover

and has an overall phase response of ±90° 200 Hz–16 kHz,

which yields exceptional system impulse response

and accurate reproduction of all signals.

The PSM-2 employs TruPower™ limiting (TPL), the

first limiting technique that accurately calculates the

power dissipation within the speaker. TPL accounts for

varying speaker impedance by measuring current, in

addition to voltage, to compute the power dissipation

and voice coil temperature.

All Meyer self-powered speakers use TPL, which

• allows the speaker to produce its highest SPL

across its entire frequency range during limiting;

• eliminates long-term power compression when

the loudspeaker is operated at high levels for

extended periods;

• protects the drivers and extends the lifetime of

amplifier and driver components.

The PSM-2 uses the Intelligent AC™ power supply,

which protects the amplifier and drivers by auto-

selecting the voltage, minimizing inrush current, filtering

EMI, and performing surge suppression. The dual-

channel amplifier (620 W/channel) is cooled by a variable-

speed primary fan that runs continuously, and a

secondary fan that turns on when the PSM-2 is operated

in hot conditions or at its maximum level for an

extended period.

The PSM-2 can be equipped to operate with the Remote

Monitoring System™ (RMS) interface network and

software application. RMS displays signal and power

levels, driver and cooling fan status, limiter activity,

and amplifier temperature for all speakers in the

network on a Windows-based PC.
