Frequently Asked Questions - MIC2S Bogen

What type of microphone can I use with the MIC2S?

The MIC2S supports both dynamic and condenser microphones. For condenser mics, enable the 24V phantom power via jumper J3. For dynamic mics, leave phantom power off.

How do I set the priority level for this module?

Priority is set via jumpers J4, J5, J6. You can choose from 4 levels: 1 (highest) mutes all lower, 2 is muted by 1 and mutes 3 & 4, 3 is muted by 1 & 2 and mutes 4, 4 is muted by all higher. See the jumper diagram in the manual.

What does the gating function do?

Audio gating reduces background noise by turning off the module's output when no significant audio is present. The gate threshold is adjustable via the front panel control. Gating can be disabled with jumper J7, but the muting detection for lower priority modules remains active.

How do I connect a microphone to the MIC2S?

Use the screw terminal block. Connect the positive signal to the + terminal, negative to -, and cable shield to G (ground). The input is electronically balanced for noise immunity.

Can I adjust the tone of the microphone?

Yes, the MIC2S has Hi-cut and Lo-cut filters. Hi-cut reduces treble above 8 kHz, Lo-cut reduces bass below 100 Hz. Both are cut-only filters controlled by front panel knobs (clockwise increases cut). Additionally, the Enhance control adds intelligibility enhancement for a crisper sound.

What is the purpose of the limiter?

The limiter prevents the output signal from exceeding a set threshold. Adjust the Limit control to set the level where limiting begins. Clockwise allows more output before limiting, counterclockwise reduces it. The limiter monitors the output level, so increasing gain affects when limiting occurs.

How do I assign the module to a specific bus?

Bus assignment is done via jumpers J1, J2, J3. You can send the signal to Bus A, Bus B, or both buses simultaneously. Refer to the jumper settings diagram in the manual.

Can I use the MIC2S as a standalone unit?

No, the MIC2S is a module designed for installation into a compatible Bogen amplifier or main unit. It requires the host for power and bus connection. It slides into a module bay and is secured with two screws.

Do I need to set up anything before installing the module?

Yes, before installation, turn off power to the host unit and make all necessary jumper selections for priority, phantom power, gating, and bus assignment. Then slide the module into the bay and secure it.

Can the MIC2S be muted by other modules?

Yes, a module set to a higher priority can mute the MIC2S if the MIC2S is set to a lower priority. For example, a Priority 1 module mutes all lower priorities. The MIC2S can also mute modules set to lower priorities.

Module Installation

1. Turn off all power to the unit.
2. Make all necessary jumper selections.
3. Position module in front of desired module bay opening, making sure that the module is right-side up.
4. Slide module on to card guide rails. Make sure that both the top and bottom guides are engaged.
5. Push the module in to the bay until the faceplate contacts the unit's chassis.
6. Use the two screws included to secure the module to the unit.

WARNING:

Turn off power to unit and make all jumper selections before installing module in unit.

Jumper Selections

Priority Level\*

This module can respond to 4 different levels of priority. Priority 1 is the highest priority. It mutes modules with lower priorities and is never muted. Priority 2 can be muted by Priority 1 modules and mutes modules set for 3 or 4. Priority 3 is muted by either Priority 1 or 2 modules and mutes Priority 4 modules. Priority 4 modules are muted by all higher priority modules.

* The number of priority levels available is determined by the module capacity of the amplifier the modules are used in.

Gating

Gating can help reduce noise in systems with multiple mic inputs. You can disable gating (turning off) of the module's output when insufficient audio is present at the input. Detection of audio for the purpose of muting lower priority modules is always active regardless of this jumper setting.

Phantom Power

24V phantom power can be supplied to condenser microphones when jumper is set to On position. Leave off for dynamic mics.

Bus Assignment

This module can be set to operate so that the MIC signal can be sent to the main unit's A bus, B bus, or both buses.

Gate

Controls the minimum necessary input signal level to turn the module's output on and apply signal to the main unit's buses. Clockwise rotation increases the necessary signal level required to produce output as well as the signal threshold necessary to cause the module to mute other modules.

Limiter (Limit)

Sets the signal level threshold at which the module will begin to limit the level of its output signal. Clockwise rotation will allow more output signal before limiting, counterclockwise rotation will allow less. The limiter monitors the module's output signal level, so increasing Gain will affect when limiting takes place.

Gain

Provides control over the level of input signal that can be applied to the internal signal buses of the main unit. Allows a way to balance the input levels of various devices so that the main unit controls can be set to relatively uniform or optimum levels.

Enhance

Controls the amount of intelligibility enhancement applied to microphone signal. Intelligibility enhancement provides a crisper sounding signal that is easier to understand over background noise. Clockwise rotation increases the effect.

Hi-Cut

Allows a reduction in the amount of treble frequencies above 8 kHz. This is a cut only filter and does not allow boosting treble. Clockwise rotation increases the amount of cut.

Lo-Cut

Allows a reduction in the amount of bass frequencies below 100 Hz. This is a cut only filter and does not allow boosting bass. Clockwise rotation increases the amount of cut.

Connections

Uses a screw terminal block to make connections to the module's input. The input is low-impedance, electronically-balanced for excellent noise immunity. Connect signal to + and - terminals and cable shield to G terminal.
