Page 4: Introduction
Bogen's M-Class amplifiers are enclosed in a heavy-gauge steel chassis, which prevents mechanical damage to the unit's internal components even if the unit is subjected to rough handling and excessive portable installa- tions.The control knobs are located in a recessed section of the cast aluminum front panel to reduce the like-... -

11. Lo-Cut Switch Select a low-frequency roll-off of 65 Hz or 125 Hz for transformer-coupled and horn speakers. Flat position allows full low-frequency performance. 12. Module Bay Accepts one or two Bogen input modules (one module included with amplifier). Panel Descriptions... -
Page 7: Installation
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 process. Remove the 6 front most cover screws on each side panel of the amplifier and attach rack ears as shown. 2. -
Page 8: Table Mounting
Ventilation The M-Class was designed to be placed on a table or rack-mounted.When rack mounted, the amplifiers can be stacked one on top of the other for maximum use of the rack. An open air space of at least 4" must be provided at the front air intakes of the amplifier, and the rear exhaust must have at least a 4"... -
Page 9: Module Installation
Module Installation Installation Two input module bays are available 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 make the desired jumper setting changes before installing the module. The sleep switch should be set to the desired position prior to installation of the right module since it will be covered by the module (see Operation, Sleep Mode Defeat). -
Page 10: Connections
Speakers Low-Impedance Speaker Connections When the amplifier is set to either the stereo mode or the Dual Mono mode (see Operation section), low-impedance speakers can be connected to either the "A" or "B" speaker output terminals. The amplifier is designed to work into speaker load impedances as low as 3.2 ohms. -
Page 11: Operation
Operation Controls & Connectors Level Controls The front-mounted level controls act differently depending on the mode of operation. In the stereo mode, each level control determines the volume of the corresponding amplifier channel as in a typical amplifier. In the 70V Mono and Dual Mono modes, the controls have a different function and determine the mix of the signal levels from the different input modules (input modules can be assigned to either the "A"... -
Page 12: Effects Loop
Effects Loop The effects loop connectors act as an insertion point for outboard signal processing equipment when the M-Class is operating in either the 70V Mono or Dual Mono modes. In these modes, the inputs and front panel controls form a 2:1 mixer. Connect the Effects Loop Out to the input of the external signal processing equipment. -
Page 13: 70V Mono Mode
The M-Class amplifier contains two separate audio buses.The "A" bus level is adjusted by the "A" level control on the front of the unit and the "B" bus is adjusted by the "B" Level control. Most Bogen modules provide a means to assign their output to either or both of the audio buses.The instructions that accompany the mod-... -
Page 14: Modules
Module Priority Bogen input modules allow for up to 4 levels of priority. Each module (except the included input module, which comes standard with the amplifier) can both be muted by higher priority modules and mute lower priority mod- ules. -
Page 15: Applications
Applications Application Examples Application 1: Simple 1-Zone, 70V Mono telephone paging system with background music Background music plays through the system when no page is being made. During a telephone page, the background music mutes to a predetermined level and the telephone page is heard.When the page is complete, the background music fades back to its previous level. -
Page 16: Applications
Application 3: Global music/message buffered and distributed to multiple amps with local override input for each amplifier Similar to the paging situation found at airport departure gates, global music/messages play when no local page is present. During local page (from departure gate microphone), music/message mutes to predetermined level and page is heard only in local area. -
