10-channel Active Speaker Power Unit for installation applications

10 x 100W/8Ω (160W/4Ω) power amps arranged in 5 HF/LF channel pairs

Line-level active crossover modules supplied with Meridian Active Installation

The C51 powers 200 and 300 Series Remote Active installation loudspeakers.

It features active line-level crossovers, switched balanced and unbalanced inputs, and employs a powerful new amplifier design which enables multiple channels of high-level amplification to be combined in a compact unit without excessive heat.

Ten channels of approximately100W into

8Ω (160W into 4Ω) RMS amplification are provided, grouped into five pairs, each providing bass and tweeter outputs from a full-range input.

The crossovers take the form of plug-in modules which can be inserted at the time of installation to configure the unit for the speakers in use. An appropriate card is supplied with each loudspeaker. Modules are currently available for the A320, A330 and A350, and each module includes a pair of LEDs that confirm the positive and negative power-rails are operative and identifies the crossover installed by means of the colour combination.

Thermal, short-circuit and DC fault protec- tion circuitry is included. The C51 has soft start, fan output and trigger input.

The front panel includes five sockets for installation of the crossover cards, which can be accessed by unscrewing the trans- parent smoked access cover.

Front-panel indicators take the form of blue LEDs for main power and for each channel, arranged in high/low pairs so that the status can be instantly assessed.

The rear panel is divided into five chan- nel pairs identified as HF (tweeter) and LF (bass). A single full-range input per chan- nel pair may be switch-selected between unbalanced (gold-plated phono connec- tor) and balanced (XLR3F).

In addition to the power input socket and power switch, the rear panel also offers a 3.5mm jack socket for connection of an industry standard trigger input (5–30V, AC or DC) for remote operation, and a 3.5mm jack socket for the connection of a 12V DC fan system. This output is controlled auto- matically according to temperature.
