Operation

Standard Input Module

The M-Class is shipped with one input module pre-installed.The module pro- vides 2 high-impedance, balanced, low- noise inputs, but can be replaced by other modules if desired. The input’s connectors, labeled A & B, correspond to the similarly marked rear speaker connections and front panel controls. The module’s inputs are permanently assigned to their respectively-labeled audio buses.

Standard Input Module Priority Jumper

The input module that comes stan-

dard (and pre-installed) with the M-Class differs in priority capability from other Bogen input modules. The module has a priority jumper that can set it to be muted by any other modules installed or to never mute. Since it is incapable of muting other modules, it is always the lowest priority module.When signaled to mute by anoth- er module, it will reduce the level of both channel’s input signals by the amount set by the ducking control (DUCK). When the mute is released, the module will fade the input signal levels back to the previous level. When set to No Mute, it does not respond to muting from other modules and is, therefore, always available for use in mixing applications. The module is factory set to be muted by any other module. The module will have to be removed to change this setting.

Standard Input Module Gain Switches

A separate gain switch for each input channel is included in the module that comes pre-installed with the ampli- fier.The module is factory set for 0 dB gain. Set each switch for the channel’s desired gain, either 0 dB (X1) or 18 dB (X8).

Other Input Modules

Various input modules can be installed in the M-Class amplifier. Refer to the instructions that come with each module for specific connection and setup information. The module jumpers must be set prior to installing the module.

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. The priority level of the module is set by the position of 2 jumpers on each module.

Note: Even though 4 priority levels are available on the Bogen input modules, only two levels can be used with the M-Class since it only accepts 2 modules.

It does not matter which priority level is set on the module, only that the intended higher priority module be set to some priority level that is higher than the intended lower priority module. However, Bogen recommends using Priority Level 1 (the highest available) for the higher priority module and Priority Level 2 for the lower priority module.

Module Controls

Each input module type has a number of controls such as Gain, Bass, and Treble.These controls affect the oper- ation of the amplifier as much as the ones mounted on the amp. Be sure to read the instructions with each module and be aware of its control setting when adjusting the overall operation of the amplifier.
