2. INTRODUCTION The CAM150 and CAM60 Paging Amplifiers are designed for continuous duty in speech, music, paging and sound reinforcement applications in churches, schools, offices, arenas, hotel meeting rooms, convention centers, recreation facilities and other venues demanding high performance, flexible features and rugged dependability. The CAM150 has a 150 watt power amplifier, and the CAM60 has 60 watts. Apart from this difference in power output, the two models are identical in details and operation.
3. FRONT PANEL FEATURES 1. INPUT LEVEL 6. POWER SWITCH These controls allow you to individually adjust the volume level of each of the four balanced inputs, and the Aux input. We recommend that you turn down the level controls of any unused or little-used inputs. Use this switch to turn the unit on or off. The power is on when the top of the switch is pressed, and off when the bottom is pressed. Turn it off if you are not using the unit for long periods of time. 2.
4. REAR PANEL FEATURES 7. DC POWER SWITCH 11. TELEPHONE PAGING VOLUME If this switch is pressed in, the unit will automatically switch to external DC battery power whenever (or if-ever) your local AC power fails. You will need to connect an external 24 Volt battery to the DC battery terminals (19). This controls the volume of any signals connected to the TELEPHONE PAGING (10) input terminals. Adjust it to suit your taste, so any pages are heard clearly.
15. INPUTS CONSTANT IMPEDANCE These inputs allow you to connect balanced XLR plugs from microphones or 1/4" TRS or TS plugs from line-level sources. To connect a speaker directly, connect the COM terminal to the negative post of your speaker, and connect the 4 Ω terminal to the positive post. INPUT 1 has "Voice Priority" over the other inputs. If an announcement is made using a microphone connected to INPUT 1, then the other inputs are over-ridden.
COM and 25V are used to connect a string of 25V speakers. Use Class II or Class I wiring: DC - 24V + COM 4 25V 70V 100V 25V 0 0 0 25V 25V The unit can be powered using a 24 VDC power supply (if the rear panel DC POWER SWITCH is pressed in). This can serve as a backup supply in case of an AC power failure. The unit seamlessly switches to the backup supply if there's a power loss, allowing safety instructions and emergency communications to continue.
5. THERMAL CONSIDERATIONS The power amplifier within the unit is convection cooled rather than fan cooled. Heat is drawn away from the amplifier by the heatsink and radiated through the cooling vents in the top cover. When installing, be sure to allow sufficient air space around the top and rear of the amplifier to allow adequate cooling for the heatsink. Leave at least one rack space above and below, and at least 6 inches behind the chassis to allow proper ventilation.
