Bosch PLM-4P220-US 4 Channel DSP 220W Amplifier for PLENA matrix

The PLM-4Px2x PLENA matrix Amplifiers are built to perform. Designed to be reliable, cost effective, multi channel amplifiers; they are suitable for almost any application that demands high quality audio and flexible control.

The built-in DSP processor is packed with powerful features. The loudspeaker library will allow the easy tuning of Bosch/EV/Dynacord loudspeaker products. The power saving mode on the amplifier allows the amplifier to save over 80% of its running costs when areas are not being used. Equipped with "Amp Link", combining both the PLM-4Px2x amplifiers with the PLM-8M8 8 Channel DSP Matrix Mixer couldn't be easier.

Some typical application include: Shopping centers, schools, restaurants, bars, nightclubs, cafes, gyms, recreational facilities, churches, warehouses, office buildings, regional airports, train stations, bus terminals, boardrooms, meeting rooms, conference facilities, small theme parks, museums, back of house performing arts centers and sports stadia.

Controls and indicators

The indicators on the front panel are; Signal/Clip, fault per channel and mains power. There are no controls on the front of the unit; this is to reduce the assistance from "overly helpful" venue staff. However, on the rear of the unit there is attenuation for the 4 output channels, dip switches for changing the input sensitivity, bridging the amplifier channels; and the mains power switch. All other controls and indicators are available via the PC GUI software.

Dynamic Bass Enhancement

An area that is tuned well and sounds good at normal levels can sound thin when the volume is turned down. The Dynamic Bass Enhancement automatically gives a more full sound even at low SPL. When the zone is restored to the normal level the bass enhancement decreases proportionally to the restore the preset level and tuning.

Standby and auto standby mode

The standby mode reduces the environmental impacts and the running costs of owning power amplifiers, making it much more cost effective and environmentally friendly than other amplifiers. Standby can be engaged and disengaged manually via the PC GUI software, or with the addition of a Bosch motion detector it can become an "auto standby mode". In zone(s) where activity has stopped the amplifier will automatically shift to a low power consumption mode after a pre determined time. When the area does become active again the amplifier simply restores to being fully active in under a second by ramping the background music back in smoothly. The amplifier also comes equipped with a 12VDC power output, to make installation of motion detectors simple and easy.
