P anel Descriptions M-Class Rear P anel 1 . Lo w-Impedance Outputs Accepts up to # 1 0 spade lugs for low-impedance speak er connections. 2. Channel Balance Only activ e in Dual Mono mode . Allows one channel’ s volume to be adjusted r elative to the other channel.
Installation Installation Components 1 . Rack Ears Prior to installing the amplifier , you will need to attach the installation rack ears if you intend to install the ampli- fier in a rack and complete the setup pr ocess. Remov e the 6 front most cov er screws on each side panel of the amplifier and attach rack ears as sho wn.
Installation V entilation The M-Class was designed to be placed on a table or rack-mounted. When rack mounted, the amplifiers can be stack ed one on top of the other for maximum use of the rack.
Installation Module Installation Installation T wo input module ba ys are a vailable to accept various Bogen input modules thereby allowing users to customize the amplifier to suit the needs of the installation. Read the instructions included with the module and mak e the desired jumper setting changes bef ore installing the module.
Connections Speakers Lo w-Impedance Speaker Connections When the amplifier is set to either the ster eo mode or the Dual Mono mode (see Operation section), low-impedance speak ers can be connected to either the "A" or "B" speak er output terminals.
Operation Contr ols & Connector s Le vel Controls The front-mounted le vel contr ols act differently depending on the mode of operation. In the stereo mode, each lev el control determines the volume of the cor responding amplifier channel as in a typical amplifier .
Operation Effects Loop The effects loop connectors act as an insertion point for outboard signal pr ocessing equipment when the M-Class is operating in either the 70V Mono or Dual Mono modes. In these modes, the inputs and front panel contr ols form a 2: 1 mix er .
Operation 70V Mono Mode Placing the 3-position switch to its right most position puts the amplifier in the 70V Mono mode of operation. The amplifier supplies a single channel of amplification in this mode (see 70V Mono Mode Block Diagram ). This mode also mix es the signals from each input module into a mono pr o- gram.
Operation Modules Standard Input Module The M-Class is shipped with one input module pre-installed. The module pr o- vides 2 high-impedance, balanced, low- noise inputs, but can be r eplaced by other modules if desired.
