Cloud MPA240 mk2 240W Zonemixer forstærker 100V/4Ohm
Cloud MPA-serien er beregnet til at give en komplet lyd løsning til installationer, detailforretninger, hoteller, mødelokaler mv., hvor musik, annonceringer og/eller fleksibel personsøgning er påkrævet.
Den kombinerer funktionerne i en to-kanal mikrofon mixer med 6-input musikkilde vælger og en mono effektforstærker i en enkelt 1U enhed.
There are two models in the MPA range, which differ only in the
rated power of the amplifier stage:
MPA120 MK2: 120 watts
MPA240 MK2: 240 watts
(ratings are into 4 ohms)
• Provides amplification and simple control of music, mic sources and paging in a single unit
• Available in two versions, with output power ratings of 120 or 240 W
• Integral two-channel microphone mixer with per-input sensitivity adjustment
• Front panel controls for music source, music level and level ofeach mic input
• Six (unbalanced) stereo line inputs with individual sensitivity adjustment
• Two balanced mic inputs – 12 V phantom power available oneither or both
• Fixed 100 Hz hi-pass mic channel filter
• Separate microphone limiter circuit to prevent power stagelimiter from ducking music signal in the presence of high mic levels
• Separate HF/LF EQ adjustments (rear panel) for mic signals and music source
• Paging control on Mic 1 input via short-to-ground access connection
• Mic 1 configurable as high-voltage input for paging from existing 70/100 V-line system
• High-voltage input alternatively selectable to Line 5 input: permits existing background music to be routed via MPA MK2.
• Selectable VOX mic-over-music priority on all mic Inputs
• Automatic Mic 1-over-Mic 2 priority in Page mode; may be overridden by internal jumper
• Selectable LINE 6 priority with choice of release times
• Selectable pre-announcement chime
• Music Mute control input (N/O or N/C) for interface to an emergency system
• Facility port for connection of LM-2, L-1 or M-1 remote input modules via screened Cat 5 cable; LM-2 also allows remote control of music level and line input selection
• Facility Port supports BT-1 Bluetooth input module
• Compatible with standard Cloud remote control plates: RL-1 Series (music level) and RSL-6 Series (music level and source selection)
• Power amplifier protection circuitry
• Power amplifier input limiter
• Transformerless output stage can be configured to drive either 70/100 V-line systems directly, or low impedance loudspeakers (4/8 ohms)
• Switchable 65 Hz low-pass filter: reduces transformer saturation in 70/100 V-line systems
• Aux output from pre-amp (balanced, line level)
• Automatic power-down function (user-selectable)
• ENERGY STAR Certification applied for
• Convection cooled (MPA120 MK2); forced-air cooling with variable speed control (MPA240 MK2)
• 1U 19†rack mounting unit
