SET-UP & USE

1. LOCATION OF THE AMPLIFIER

First, ﬁnd a suitable location to set-up the ampliﬁer. It is best to put the ampliﬁer in a stable location near the other equipment to be used. It can be set in a cabinet, on a tabletop, or mounted on the wall with the included bracket.

Media Cabinet Set-up

Wall-mount Set-up

The included wall bracket is speciﬁcally designed to support the CAT 860.

Next, ﬁnd a suitable location for the ISR. Poor location will cause substandard performance of the CAT 860 Classroom Audio System. The ISR should be as high as possible in the room – the ceiling is the best location, centered along the longest wall in the room. When possible, use a conduit to protect the wires (not included). Poor choices for placement are corners, on walls at heights lower than 7 feet (2 meters), or in places where the line of sight from the ISR to the receiver is or could be obstructed.

1. Overview 2. Setup & Use

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.

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

1. Turn the CAT 860 power on. The blue LED will glow.

2. Remove the REDMIKE from the charging cradle and turn it on.

3. Slip the REDMIKE with lanyard around the neck and position the top of the microphone just below the collarbone. NOTE: Positioning of the REDMIKE is critical for proper volume adjustment.

4. While speaking in a normal voice slowly increase the volume of the corresponding channel on the CAT 860 until your voice is barely audible. Each REDMIKE has its channel pre-set to either A or B, as indicated on the back of the Mic.

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.

5. Once initial volume level is set, walk around the room and listen for audio dropout and overall audio quality. Fine-tuning the audio is accomplished by making minor adjustments to the 4-Band Equalizer on the back panel of the CAT 860.

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

9. AUDIO EQUALIZATION OF THE CAT 860

The CAT 860 uses a 4-band audio equalizer designed to optimize and ﬁne-tune the microphone sound quality for the classroom. Below are some tips on proper system equalization:

• Thevoiceshouldbenatural,

very clear and without any audio feedback (ringing)

• Walktheroomlisteningforthe

overall quality and any feedback that is present

• Ifthereisalotofaudiofeedback,

it is likely the volume is too high. Ensure the volume is at the appropriate level, a second person is helpful to determine this.

• Iffeedbackisstillpresentwiththe

audio set at the right level, make the following EQ adjustments:

– High pitched ring: lower the 2K

and/or 4K adjustment by _ turn

– Lower pitched ring: lower the

500 and/or 1K adjustment by _ turn

• Ifyounoticethesoundis“muddy”

or has too much bass:

– Lower the 500 adjustment by _

turn and/or

– Raise the 2K or 4K adjustment by

1/8 turn

• Note:theEQadjustmentsshould

be preset at “12:00.” This is the nominal level and any adjustments (up or down) should be made from this level.

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 3.5 mm to

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

3. Connect a patch cable from the ALD’s microphone jack or AUX input to one of the following

3.5mm audio jack on the CAT 860:

11. 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 CAT 860 (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.

12. PAGEFIRST: PRIORITY MUTE

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

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 CAT

860.

3. As a page is broadcast, the sensor clip detects the audio signal through induction and immediately mutes the CAT 860.

4. When the page is over, the audio from the CAT 860 returns to normal volume level.

RS-232 Data Signals

RS-232 LOGIC WAVEFORM (8N1)

Command and parameter characters travel serially along the RS-232 signal link between the external controller and the CAT 860. The command and parameter information is in the form of two hexadecimal values contained in the 8-data bits of each RS-232 character. The above graphic illustrates a typical RS-232 logic waveform representing a character (Data format: 1 Start bit, 8 Data bits, No Parity, 1 Stop bit). The data transmission starts with a Start bit, followed by the data bits (LSB sent ﬁrst and MSB sent last), and ends with a “Stop” bit.

The voltage of Logic “1” (Mark) is between -3VDC to -15VDC, while the Logic “0” (Space) is between +3VDC to +15VDC.

Command Structure

An external controller, in the form of an intelligent wall panel or a personal computer, can use the RS-232 serial link to remotely send commands to initiate actions or queries for the CAT 860. In response, the CAT 860 uses the RS-232 serial link to send acknowledgements or status data back to external controller.

There are two operational command sets; the Basic Command Set for audio switching and the Advanced Command Set for audio mixing. It is not recommended to intermix commands from the two command sets.

The Basic Command Set treats the CAT 860 as a simple audio switcher where only one of four audio/video sources is enabled at one time. The two microphone channels are controlled as a pair independently from the audio/ video sources. The low-cost serial controllers with their limited functionality will typically will be restricted to a subset of the Basic Command Set. These controllers usually cannot utilize the query commands, or the response packets. More capable high-end serial controllers can take advantage of the complete features of the Basic Command Set.

The Advanced Command Set treats the CAT 860 as an audio mixer which is aligned with the traditional usage for Lightspeed CAT 800 series products. The Advanced Command Set requires the more capable high-end serial controllers to utilize the CAT 860 to its greatest potential.

It is expected that each button press from the serial controller would use only a single action/query command packet. If a single button press must issue a string of multiple action/query command packets then each packet must be separated by at least a 10ms delay, or alternately, a new command packet must wait until the CAT 860 issues a response packet/character before it can be sent.

2. Make sure the cradle charger is plugged into a wall outlet. Connect one end of the charging cable into the jack labeled CHARGER on the side of the LT-71 and plug the other end into the charging jack on the rear of the REDMIKE cradle charger. The LT-71’s rechargeable batteries are factory installed. The LED on the front of the LT-71 will glow RED when charging.

3. Leave the LT-71 plugged in overnight (8–10 hrs.) to obtain a full charge.

NOTE: If the system was purchased without a REDMIKE or REDMIKE VC, the LT-71 will utilize a charging cable. Simply connect the charging cables to the jacks labeled CHARGER on the back of the ampliﬁer and connect the opposite ends to the jacks on the back of the cradle charger.

Once the LT-71 is charged, follow these steps to set it up for use.

1. Turn the CAT 860 power switch to the ON position. The RED LED on the switch will glow.

2. Turn on the LT-71 and set the operating channel to “B”.

3. Slip the LT-71 with lanyard around the neck and position the top of the microphone just below the collarbone. NOTE: Positioning of the LT-71 is critical for proper volume adjustment.

4. While speaking in a normal voice slowly increase the volume for Channel B on the CAT 860 until your voice is barely audible.

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.
