SET-UP & USE

1. DETERMINE SET-UP LOCATION

1A. TO SET-UP ON TABLE-TOP

Tabletop (recommended):

• Virtually no setup time

• Greater ﬂexibility to move to different locations

First, consider that the REDCAT Media should be placed within within 7 feet of an electrical outlet and on a surface about 3-6 feet off the ground.

Next, ﬁnd a location as far away as possible from the teacher who will be using the mic. The best place is against the wall opposite where the

teacher will be speaking. If this is not possible, other good locations are along either wall next to the teacher or in a corner. Avoid placing the REDCAT Media next to where the teacher instructs. Putting the REDCAT Media in close proximity to the teacher’s mic can result in feedback.

Wall-mount:

• More permanent setup

• Greater security

Avoid!

4. CHARGING THE REDMIKE

Before use, the REDMIKE should be charged. It will take 8-9 hours for the REDMIKE to obtain a full charge. A fully charged REDMIKE will last for over 7 hours of use. If microphones are used daily, they should be kept in the cradle – microphones can be left in a charging cradle constantly for up to 2 weeks without causing degradation to battery life.

A red light on the charging cradle indicates the REDMIKE is charging. A green light indicates that charging is complete and a full charge has been reached. A blinking light indicates a charging or sensing error. See Troubleshooting section for more information.

REDMIKE incorporates alkaline protection into the microphone design. Always use a Lightspeed rechargeable sensing battery. Replacement AA NiMH batteries may only be purchased through Lightspeed Technologies (part # BA-NH2A27). Do not attempt to charge alkaline batteries. They can overheat and expand creating a signiﬁcant hazard and damaging the microphone (this is not covered by warranty).

1. Plug power cord into the cradle charger and then plug the AC end into an electrical outlet.

2. Ensure that the REDMIKE is turned OFF.

3. Place the REDMIKE into the cradle. The LED on the cradle will glow RED indicating charging has started. When the REDMIKE is fully charged the LED on the cradle charger will change to GREEN.

5. OPERATING THE REDMIKE

Once the REDMIKE is charged, follow these steps to set it up for use.

1. Turn the REDCAT Media power switch to the ON position.

2. Remove the REDMIKE from the charging cradle and turn it on. The red IR LED (CH. A or CH. B) on the REDCAT Media will light to indicate a signal is being received.

3. Slip the REDMIKE with lanyard around the neck and position the top of the microphone just below the collarbone.

4. Slowly increase the CH. A/B volume up to the “green” section of the dial. This designates normal volume range in the classroom.

5. While speaking in a normal voice, ﬁne-tune the volume up or down. Proper volume level should be as follows:

• Your voice should be clearly

heard by another person on the other side of the room.

• You should barely be able to

hear your own voice.

• There should not be any audio “feedback” or squealing outside of 2-3 feet (if there is, turn the volume down slightly).

REMEMBER: This equipment supplements the user’s voice so they are able to speak in a conversational tone. Having the volume set too high will result in feedback and listener fatigue.

6. Once initial volume level is set, walk around the room and listen for audio dropout and overall audio quality.

7. If further ﬁne-tuning is required, audio equalization may be necessary. Please refer to the following page.

8. If a second REDMIKE was purchased, repeat steps 2-4.

Fine-tuning Audio

Optional PageFirst Interface

If the volume is set properly, but there is still a small amount of audio feedback (squealing) some audio equalization may be necessary. Follow the steps below to properly EQ the system:

This optional feature interfaces with an independent classroom paging system. When the page is broadcast, all audio from the system is muted, ensuring important and even emergency school-wide messages are never missed.

(For full installation details refer to the install sheet included with the optional PageFirst sensor clip)

1. Slide up and ﬂip down the EQ cover door.

2. Walk the room listening for feedback (squealing).

3. Lower the 2K5 and/or 4K sliders if a high-pitched ring is present.

4. Lower the 400 and/or 700 sliders if a low-pitched ring is present.

5. If feedback is still present, it is likely the volume simply needs to be turned down.

How it works:

1. PageFirst sensor clip is hung around the lead wires attached to the classroom paging speaker.

2. The clip is hard-wired to the REDCAT Media.

3. As a page is broadcast, the sensor clip detects the audio signal through induction and immediately mutes the REDCAT Media.

4. When the page is over, the audio from the REDCAT Media returns to normal volume level.

1. Turn the ALD (Assistive Listening Device) volume control on the REDMIKE side panel all way the down.

2. Determine the size and type of audio input jack on the device as many manufacturers’ products differ in connector size and shape. The Lightspeed LES-370 Personal FM System requires a 3.5mm to

3.5mm patch cable (part# CAMMC3535, not included).

3. Connect a patch cable from the ALD’s microphone jack or AUX input to the 3.5mm audio jack labeled “ALD OUT” on the side

of the REDCAT Media.

4. Adjust the volume control on the ALD’s receiver to maximum output. NOTE: This is to set the maximum allowable signal from the REDCAT Media.

5. With the REDCAT Media and ALD turned on, speak into the REDMIKE and slowly adjust the ALD volume control until the appropriate audio level is attained in the ALD’s receiver headphones.

USING THE REDMIKE TO AMPLIFY EXTERNAL AUDIO EQUIPMENT

The REDMIKE includes a 3.5mm audio input jack to connect to an audio source like a laptop or MP3 player. The REDMIKE will transmit the audio signal to be played through the system.

If your system includes two REDMIKEs, we recommend using Channel B (student mike) to amplify the external audio equipment so the teacher’s volume on the Channel A (teacher mike) does not have to be adjusted.

To determine which REDMIKE is set to Channel B, you can look at the switch on the back of the mike or speak into one of the mics and watch which set of LED’s glow on the front panel of the REDCAT Media (A Volume or B Volume correspond to Channels A or B).

1. Plug your external audio equipment (for example, laptop), into the input on the REDMIKE labeled “INPUT” using a 3.5mm patch cable.

2. Adjust the volume of the selected mic channel to achieve desired loudness.

INITIAL SET-UP: OPTIONAL IR MEDIA CONNECTOR

1. Turn off the second microphone. The iR Media Connector uses the same channel (channel B) as the optional second microphone (REDMIKE, LT-71, or REDMIKE Share). As a result, they cannot be used simultaneously. If you have a second microphone, turn it off before transmitting audio from the iRMC.

NOTE: If you adjust the CH B volume on the classroom audio system, you will also be changing the volume for your second microphone. Return the CH B volume knob to the original position before turning the second microphone back on.

2. The iR Media Connector volume is preset for most standard audio signals. If you need to turn the volume up or down, follow this procedure:

A. Adjust the volume at the

computer, television, or other audio source if possible.

B. If the audio source does not have a volume control (such as many DVD players) adjust the volume at the iRMC.

3. If the ﬁrst two options do not give optimum volume level, the last place to adjust the volume is the CH. B Volume on the classroom audio system

(REDCAT Media or other).

• Speak in a natural voice. A normal conversational speech level will provide an adequate signal. It is not necessary to increase the intensity of your voice—the audio system provides adequate ampliﬁcation (approximately 5 – 10 dB) above ambient room noises.

• Avoid wearing jewelry that may rub or bump against the microphone.

• Turn the REDMIKE off during private conversations with a student, parent, or other classroom visitor. You can also cover the LED lens on top of the REDMIKE to block the signal.

• Recharge batteries each night. When recharged nightly, operating time (actual usage) for the transmitters will last through a typical school day.
