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. Wall-mount Set-up Good placement Best placement 3. Optional Accessories 3. Optional Accessories Media Cabinet Set-up 5. Warranty, Safety & Specifications Next, find a suitable location for the ISR.
Once you find a suitable location for the ISR, follow these instructions to mount it. There are different instructions for mounting depending on if the ISR will be mounted to a suspended ceiling grid or secured to a wall / solid vertical surface. Suspended Ceiling Mount 2. Setup & Use 1. Screw the bracket to a place high on the wall or in the middle of the solid ceiling. Mount the bracket horizontally as shown above. 2. Uncoil the Cat 5 sensor cable. Connect one end of the cable to the ISR.
The CAT 860 systems include a bracket for optional wall-mounting. 2. Connect the CD end of the power supply to the black power jack labeled DC POWER. 1. Overview a. It should be located near a power outlet. b. Height should allow for access to front control panel, but also be in compliance with building and ADA regulations. Front Panel 1 + Control Select - CAT 860 Amplifier RS-232 - + 2 RS-232 IN B. Screw the bracket to the wall at the two screw hole points with the included hardware.
1. Ensure speaker wire connections are secure and not frayed. *Note: Wiring to these terminals should follow the Class 2 wiring methods as outlined in the National Electric Code. 1. Ensure the power is switched off and the audio input volume controls are turned all the way down. 3. With both the CAT 860 and the audio source power on, adjust the corresponding volume control on the CAT 860 until the desired level is achieved.
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.
1 + RS-232 Control Select - - + 2 RS-232 IN • 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: – Raise the 2K or 4K adjustment by 1/8 turn • Note: the EQ adjustments should be preset at “12:00.
1. PageFirst sensor clip is hung around the lead wires attached to the classroom paging speaker. 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). 2. The clip is hard-wired to the CAT 860. 5. Warranty, Safety & Specifications 4.
