Section 1 Getting Started 1

1 Getting Started

The Loudmouth®is a radio receiver that allows you to use your portable, base station or

mobile 2-way radio to deliver voice messages directly to a PA speaker up to 2 miles away.

The receiver and PA speaker is the ideal solution where hard-wired PA installation is simply

impossible, too expensive, or temporary.

Your Loudmouth®receiver and PA speaker has been designed so that you can set it up

quickly and start using it right away.

Section 1 Getting Started 3

1.3 Paging the Loudmouth®receiver and PA speaker

The Loudmouth®receiver and PA speaker can be paged with 2-way radios programmed for Quiet Call (CTCSS), Digital Quiet

Call (DCS), 2-Tone Paging, or Selcall paging formats. Each format offers a unique method of paging the Loudmouth®receiver

and PA speaker.

Refer to the Programming section of this manual for specific instructions on programming your Loudmouth®receiver and PA

speaker to one of these selective signaling formats.

Ritron strongly recommends operation of the Loudmouth®receiver and PA speaker

with one of the following selective signaling formats enabled.

Paging the Loudmouth®with Quiet Call (CTCSS) only:

To page the loudspeaker a user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth®

channel.

Your 2-way radio must be programmed for a channel dedicated to Loudmouth® operation. Only those radios

programmed with the Loudmouth® channel will be able to access the loudspeaker.

The 2-way radio’s Loudmouth® channel and the Loudmouth® receiver must be programmed for the same QC code.

All Ritron radios offer 50 different field-programmable QC codes from which to choose.

Paging the Loudmouth®with Digital Quiet Call (DCS) only:

To page the loudspeaker a user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth®

channel.

Your 2-way radio must be programmed for a channel dedicated to Loudmouth® operation. Only those radios

programmed with the Loudmouth® channel will be able to access the loudspeaker.

The 2-way radio’s Loudmouth® channel and the Loudmouth® receiver must be programmed for the same DQC code.

All Ritron radios offer 104 different field-programmable DQC codes from which to choose.

Paging the Loudmouth®with 2-Tone Paging:

To page the Loudmouth® the 2-way radio must first send the correct 2-Tone Paging code. Once access to the

loudspeaker is accomplished, the user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth®

channel. After a period of inactivity the Loudmouth® is automatically reset, and will then require the correct 2-Tone

Paging code to re-gain access.

Only 2-way radios programmed to send the correct 2-Tone code on the Loudmouth®channel can access the

Loudmouth®wireless PA speaker. However, once access is gained, any 2-way radio that operates on the

Loudmouth®channel can access the loudspeaker up until the time that the Loudmouth®has automatically reset.

Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth® receiver must

be programmed for the same QC or DQC code.

Paging the Loudmouth®with Selcall:

To page the Loudmouth® the 2-way radio must be programmed to send the correct Selcall code every time the PTT

is pressed. The user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth® channel.

Only 2-way radios programmed to send the correct Selcall code on the Loudmouth®channel can access the

Loudmouth®wireless PA speaker.

Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth® receiver must

be programmed for the same QC or DQC code.

Section 1 Getting Started 4

Ritron recommends the use of a dedicated channel frequency for Loudmouth®

operation.

When operating on unique frequencies dedicated to loudspeaker operation:

Your 2-way radios must be programmed for a channel dedicated to loudspeaker operation.

Loudspeaker operation is limited to radios programmed with the dedicated Loudmouth®channel.

The use of 2-tone or Selcall paging to address the Loudmouth®is not required, but can still be used if additional

access security is desired.

Without 2-tone or Selcall paging the loudspeaker can be addressed by simply selecting the Loudmouth®channel on

your 2-way radio and pressing the PTT button to talk.

You may need to license additional frequencies (not necessary with LM-V150 programmed for MURS frequencies,

see Table 1 in the Programming section).

When operating on your normal 2-way communication frequencies:

Messages broadcast on the Loudmouth®are also heard on your 2-way radios.

Loudspeaker messages are not possible when the channel is being used for 2-way communications.

The use of 2-tone or Selcall paging is required to address the Loudmouth®, otherwise all 2-way communication is

heard on the loud speaker.

Any user on your 2-way channel can broadcast over the loudspeaker once it is activated, even if their 2-way radio is

not programmed with the correct 2-tone paging code.

There is no need to license additional frequencies.

1.4 Compatibility with other RITRON model radios

The Loudmouth®receiver and PA speaker is available in both VHF (LM-V150, 150-165 MHz) and UHF (LM-U450, 450-470

MHz) business band frequencies. Loudmouth®can be accessed with radios programmed for Quiet Call (CTCSS), Digital Quiet

Call (DCS), 2-Tone Paging, or Selcall paging formats. The following chart can be used to determine compatibility with existing

Ritron radios.

1.5 Determine the volume setting

Selecting the correct volume level is critical to the performance of the Loudmouth®receiver and PA speaker. Carefully consider

the following before deciding on the appropriate volume setting. Refer to the Programming section of this manual for specific

instructions on programming the Volume Level.

Ambient noise level should be considered first when selecting the volume level.

Increasing the volume level in an effort to cover a wider area will result in:

Undesirably high volume when near the speaker.

Low volume at the outer edges of the coverage area.

A calling radio must be a greater distance from the Loudmouth®speaker to prevent feedback. (Feedback is the

result of Loudmouth®speaker audio getting into the calling radio’s microphone.)

When coverage of a large area is required, additional Loudmouth®speakers may be necessary for satisfactory

performance. See the Installation section of this manual for details on how to install 2 speakers using a single Loudmouth®

receiver, or multiple receivers and speakers.

1. Refer to the horizontal shaded bars on the chart below to

determine the sound level that best represents your location. This

should be the ambient, or average sound level. We will consider

the maximum sound level when we locate the speaker.

2. Estimate the maximum distance (in feet) that the loudspeaker

must be heard. Locate that distance on the chart below and

follow it up to find the line that is in the middle of your shaded bar.

This line indicates the optimum Loudmouth®volume level setting.

EXAMPLE: In the Ritron factory we need to

cover a maximum distance of 50 feet on the

factory floor with an ambient sound level similar

to a warehouse. I find the vertical line at the

bottom of the chart indicating 50 feet, and follow

it up to the shaded bar indicating Warehouse.

The 50% and 75% lines are in the middle of the

Warehouse bar, indicating a required

Loudmouth®volume setting between 50 - 75%.

Section 2 Installation 6

2 Installation

Proper installation of the Loudmouth®wireless PA speaker is critical to the performance and

overall satisfaction with your system. With careful consideration and planning Loudmouth®

will cover up to 100 feet with a single speaker, and can cover an even wider range with

multiple speakers and receivers. This section will help you plan an installation that is best

suited for your environment.

2.1 Selecting the PA speaker location

Speaker location is critical to the performance of the Loudmouth® receiver and PA speaker. Consider the following factors

before selecting a speaker location.

The speaker can be installed either indoors or outdoors.

Be sure there is a convenient source of 110VAC power for the RPS-1B power cube and that the radio receiver box can be

located inside, out of the elements. The speaker has a 25 ft. cable, if you need more a standard RCA phono cable

extension can be used (ie. Radio Shack Catalog #: 4202362).

The speaker should not be in an area where the 2-way radio user addressing the speaker will typically be located. If the

radio user is too close to the Loudmouth®speaker, feedback can occur due to loudspeaker audio getting into the radio

microphone. This is a problem related to the 2-way radio, not the Loudmouth®speaker. The use of the Record & Play

feature will eliminate this problem.

The speaker must be located at least 10 feet above head level.

At near range the Loudmouth®speaker is capable of sound levels that can cause permanent

hearing loss and should never be installed in a location where a person could be directly in

front of the speaker.

Install the Loudmouth® speaker close to the noisiest area you plan to cover.

If there is an area with a significantly higher ambient noise level, the Loudmouth® speaker should

be located as close as possible to this area. The speaker volume must be 6 db higher than the

ambient noise level in order to be heard. If the speaker is not close to the highest source of noise,

the volume level will be too loud for the quieter areas.

Section 2 Installation 7

The Loudmouth®speaker should be mounted as high as practical and pointed toward

the farthest location you need to cover.

Large obstructions will significantly reduce the coverage area.

Do not place the speaker behind large, tall objects.

Section 2 Installation 8

2.2 PA Speaker installation

The speaker mount can be installed vertically on a wall, flat post or support

column; or can be mounted horizontally from a ceiling or rafter beam.

Once the speaker location has been determined the Speaker Mounting

Template may be used to mark the mounting surface. When using the

Speaker Mounting Template keep in mind that the speaker wire exit is

toward the floor on a wall mounted installation, and toward the front of the

speaker in a ceiling mounted installation.

The Loudmouth®speaker may be secured to a variety of surfaces, with

each installation presenting unique requirements for mounting hardware.

With this in mind, mounting screws or hardware are not included with the

Loudmouth®.

Guidelines for mounting the Loudmouth®speaker:

The Loudmouth®speaker can be safely mounted to concrete, metal or wood surfaces. Other surfaces are possible

provided they can support the weight of the speaker. If mounting to a drywall or concrete surface the use of expansion

anchors is recommended.

Secure the speaker tightly to the mounting surface, using all 6 mounting holes if possible. At high audio output levels

the speaker can generate significant vibration and must be rigidly secured. This is particularly critical with drywall

surfaces, which are highly susceptible to vibration damage.

Be sure the speaker wire exits cleanly from under the speaker mounting bracket through the wire exit tunnel provided.

Pinching the speaker wires could cause a short that will destroy the Loudmouth®receiver audio amplifier.

Route the speaker wire closely against a wall or support beam. Speaker wire hanging in free space is easily snagged

and could be pulled from the Loudmouth®receiver or worse yet, pulled from the speaker itself causing permanent

damage.

1 inch long, #8 or #10 round-head screws should be used to mount the speaker. Wood screws, sheet metal screws,

machine screws with nuts, or drywall anchors and screws will all work well depending on your specific requirements.

Pan-head screws should not be used to prevent damage to the mounting bracket due to over-tightening.
