FRONT PANEL FEATURES 1. INPUT LEVEL 5. MASTER VOLUME These controls allow you to individually adjust the volume level of each input. We recommend that you turn down the level controls of any unused or little-used inputs. Unity gain is straight up. The main output program is a mix of all inputs playing, and either Aux 1 or Aux 2. 2. AUX 1/AUX 2 SELECTOR Use this volume control to adjust the sound output level to your speakers. Adjust the master level and the input levels to average settings, not too high and not too low. For example, if you find you have to turn the master volume up high, then the input level controls might be set too low. If the master volume becomes loud after a small rotation, then the input level controls might be set too high. 6. STATUS LEDS This high-quality toggle switch selects either Aux 1 or Aux 2 to be the auxiliary input passed through to the amplifier section. The Aux 1 and 2 inputs on the rear panel are unblanced RCA line-level connections. These LEDs show: OVERLOAD (RED) SIGNAL PRESENT (AMBER) The Aux master level control below the selector switch increases or decreases the signal level of the selected Aux input to the amplifier. 3. EQ-LOW FAULT (RED) POWER ON (GREEN) 7. POWER Turn this clockwise to boost the level of the low-frequency range below 100 Hz. Turn it counter-clockwise to cut the level. In the detented center position, there is no change in level. The maximum boost and cut is 12 dB. 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. 4. EQ-HIGH Turn this clockwise to boost the level of the high-frequency range above 10 kHz. Turn it counter-clockwise to cut the level. In the detented center position, there is no change in level. The maximum boost and cut is 12 dB. 1 – CAM160 / CAM80 2 3 4 5 6 7 4. REAR PANEL FEATURES 11 Inputs 1 and 2 8 Inputs 1 and 2 have identical connections and controls, with the exception that Input 1 has an extra DIP switch to select an internal transformer. 12 9 INPUT CONNECTORS Inputs 1 and 2 each have four different styles of input connections. Choose one which suits your system the best: 8. Combination XLR/TRS connector. This can accept a male balanced XLR connector, a balanced TRS or unbalanced TS 1/4" connector. 9. Phoenix (Euroblock) connector. This three-pin connector accepts the positive, negative and ground terminals of a balanced audio line. It accepts a push-in connector for easy installation. 10. Terminal strip. This three-terminal connector accepts the positive, negative and ground terminals of a balanced audio line. Secure the connections with the screws. All inputs are designed to accept balanced or unbalanced microphone-level signals, or may be configured to accept line-level signals by means of the DIP-switch (see below). 11. GAIN pot and LED This screwdriver-adjustable rotary potentiometer acts as a trim control, and a red indicator LED displays the nominal input level. With normal source material playing, adjust the pot until the LED lights only occasionally during the loudest moments of your program. (The LED will light 3 dB before clipping.) 12. DIP switches Input 1 has an eight-pole DIP-switch from which the inputs (all four types) can be configured. Input 2 has a seven pole DIP-switch, identical to the first seven poles of Input 1. DIP # Purpose DOWN UP 1 Mic/Line Line Level Mic Level 2 Mic/Line Line Level Mic Level 3 24 V Phantom OFF Enabled 4 High Pass Filter Enabled OFF 5 -10 dB Pad Enable OFF Enabled 6 Ducking Threshold OFF see table 7 Ducking Threshold OFF see table 8 Transformer Enable (input 1 only) OFF Enabled 10 DIP switch details: 1. Mic/line (line-level is default). Select UP if using a microphone, or DOWN if it is a line-level input such as from a CD or DVD player. Note: You must set DIP 2 to the same setting as DIP 1. 2. Mic/Line. Set this to whatever DIP 1 is set to. See above for details. 3. Phantom Power. Select UP if using a microphone that requires phantom power, otherwise, it is important to keep this DOWN. 4. High-pass filter enable. The default position is enabled (DOWN). This rolls off the low frequencies below 120 Hz, at a rate of 12 dB per octave. Use this to reduce low frequencies, such as from low bass notes, microphone handling and stage noise. It is useful when using smaller speakers that do not reproduce the low frequencies well. 5. 10 dB pad enable. Select UP to reduce the input level by 10 dB. 6. and 7. Ducking Threshold Select. Use these two in combination to select the threshold when ducking occurs. See Ducking Threshold and table below. 8. Transformer enable. Select UP to engage the inline audio transformer (input 1 only). Ducking Threshold DIP-switches 6 and 7 are used in combination with each other to determine the threshold that the signals from input 1 or 2 must cross to initiate automatic ducking of the other inputs. This table shows the combinations: DIP 6 DIP 7 RESULT DOWN DOWN No Ducking UP DOWN - 10 dB Duck threshold DOWN UP - 20 dB Duck threshold UP UP - 30 dB Duck threshold CAM160 / CAM80 – Ducking will take place within 300 mS of detecting that an input signal has crossed the ducking threshold. This delay also applies to the manual activation of the Priority circuit by the use of external contact closures. Inputs 3, 4, 5, 6 Inputs 3, 4, 5 and 6 have identical connections and controls. (Input 3 is shown here.) When the signal that initiated the ducking stops, or manual activation has ceased, there will be a one second timeout period to make sure it is completely over. When it is over, the other inputs will ramp up to their original volume over the next 0.5 seconds. 15 17 18 16 14 INPUT CONNECTORS Inputs 3-6 each have two different styles of input connections. Choose one which suits your system the best: 15. Phoenix (Euroblock) connector. This three-pin connector accepts the positive, negative and ground terminals of a balanced audio line. It accepts push-in connectors for easy installation. 13 13.Priority Functions 16. Terminal strip. This three-terminal connector accepts the positive, negative and ground terminals of a balanced audio line. Secure the connections with the screws. Priority means that you can manually duck the other channels using an external switch, and play only input 1 or input 2. Priority functions can be initiated by a user-supplied, normally open, dry contact closure switch (or switches) connected to the terminal strip (GND, Priority 1, Priority 2). Connecting one leg of the switch to the GND screw and the other side to either PRI 1 or PRI 2 prepares the circuit. Closing the switch actuates the specific priority, allowing input 1 or 2 to play 14.Chime Function Chime functions can also be initiated by means of usersupplied, normally open, dry contact closure switch (or switches) connected to the terminal strip (COM, Chime 1, Chime 2). Connecting one leg of the switch to the COM screw and the other side to Chime 1 or Chime 2 prepares the circuit. Closing the switch actuates the Chime. – CAM160 / CAM80 All inputs are designed to accept balanced or unbalanced microphone-level signals, or may be configured to accept line-level signals by means of DIP-switches 1 and 2 (explained below). 17. GAIN pot and LED This screwdriver-adjustable rotary potentiometer acts as a trim control, and a red indicator LED displays the nominal input level. With normal source material playing, adjust the pot until the LED lights only occaisionally during the loudest moments of your program. (The LED will light 3 dB before clipping.) 18. DIP switches Each input 3-6 has a five-pole DIP-switch from which the inputs (both types) can be configured. (These are identical to the first five switches of inputs 1 and 2 described on page 5.) DIP # Purpose DOWN UP 1 Mic/Line Line Level Mic Level 2 Mic/Line Line Level Mic Level 3 24 V Phantom OFF Enabled 4 High Pass Filter Enabled OFF 5 Pad Enable OFF Enabled 24 23 22. Chime Level Control 22 This potentiometer controls the chime level when it is actuated (via contact closure at the chime barrier strip). Adjusting the potentiometer effects the chime level passed on to the amplifier section. It has a range of ± 10 dB. 23. Low Cut Filter 25 26 21 20 19 19. Auxiliary Inputs 1 and 2 Unbalanced, auxiliary signals enter the amplifier via 2 pairs of RCA connectors. Attenuation is controlled by the AUX potentiometer on the front panel of the amplifier. Select either Aux 1 or Aux 2 using the front panel selector switch (item 2 on page 4). The selected Aux input is routed to the mixing section of the amplifier. 20.Processing Loop External processing is possible by using the Pre-out/Amp-in processing loop. The PRE-OUT RCA connector is preamplifier, and represents the same mix as the amplified output, adjustable by the EQ and the Volume controls. The amplifier ships with a high quality “U” jumper installed. To connect an external mono processor, first pull out the "U" jumper, and connect the PRE-OUT to the input of your external processor. Connect the output of your external processor to the MAIN IN. Use high quality RCA patch cords, as short as possible to do the job. There will be no output if the U jumper is missing, so check this as a troubleshooting measure. Press this button in to engage the low-cut filter on the output of the amplifier. It is fixed at 100 Hz with a 12 dB slope per octave, and it serves to minimize transformer saturation in constant voltage systems. Frequencies below 100 Hz are attenuated at a rate of 12 dB per octave. 24. Priority Depth Level When a priority signal is detected, this potentiometer controls the depth (attenuation) of signals that are being “ducked.” In the fully CW position, no attenuation will occur. In the fully CCW position, all signals that are not a priority signal are completly muted. 25. External Volume Control This terminal is provided for remote volume control. If you connect a (user-supplied linear-taper 10K pot), you can remotely control the volume of the amplifier in the same way that the front panel volume control does. 26. Fault Relay If a fault is detected in the amplifier section, the positive terminal of this external connector is energized. This external connector can be used to connect to an external device to initiate a “fault” action as dictated by the user. Additionally, the “fault” LED on the front of the amplifier will light. 21.Tape Outputs and Gain The Tape-out output can be used to drive an external recording device. The signal exiting this stacked RCA pair is the same as the audio mix, pre-master volume control, and can be used to drive a second amplifier at line level. It’s output level is controlled by a potentiometer just above the RCA jacks. CAM160 / CAM80 – 29 27 HIGH IMPEDANCE If you are using a constant-voltage distributed speaker system, connect either the 25 V, 70 V, or 100 V output terminal to the "+" side of the speaker system, and connect the upper "GND" output terminal to the "–" side of the speaker system. The voltage of your speakers must equal the voltage of the amplifier's output terminal ( 25 V, 70 V, or 100 V). 28 27. Output Connectors This is a five-position barrier strip for connection of speaker loads. Each terminal accepts bare wire from 22 AWG to 10 AWG, or spade lugs sized for the same range of conductors. CAUTION: Make sure that you do not overload the amplifier. This may cause overheating to the amplifier, and possible damage to your speakers. To avoid overloading, make sure that the taps on the speakers add up to no more than 80% of the rated power of the amplifier being used (CAM160: 128 watts, CAM80: 64 watts). For example, for the CAM160, you could use a maximum of 12 speakers with 10 watt taps (12x10 = 120 watts). For further protection, use these figures as the maximum power sum of all the speaker taps: CAM160: 100 watts, CAM80 50 watts. Terminals are provided for 4 ohm low-impedance loads or 25, 70 and 100 Volt high-impedance loads. CAUTION: To prevent the risk of electric shock, never touch the bare wires coming from the OUTPUT TERMINALS of the amplifier when it is switched on. When the connections have been made, insulate the 25 V, 70 V, and 100 V terminals of the amplifier using the protective cover supplied. All outputs with the exception of the 4 ohm output are transformer isolated. GND and 25V are used to connect a string of 25V speakers. Use Class II wiring: LOW IMPEDANCE To connect a speaker directly, connect the lower GND terminal to the negative post of your speaker, and connect the 4 ohm terminal to the positive post. Make sure that your average speaker impedance is not less than 4 ohm, as this may overload the amplifier. The speaker output connectors are screw terminals. Use 16 or 18 gauge wire for connecting the amplifier outputs to the speakers. Strip the wire back about 3/8" inch, loosen the screw enough to loop the wire around the shaft of the screw (clockwise), and tighten down the screw with a screwdriver. 0 – CAM160 / CAM80 + 0 25V 0 25V GND and 70V are used to connect 70V speakers. Use Class II wiring: 0 - 25V 70V 0 70V 0 70V GND and 100V are used to connect 100V speakers Use Class II wiring: 0 100V 0 100V 0 The unit seamlessly switches to the backup supply if there's a power loss, allowing safety instructions and emergency communications to continue. When both AC power and 24 VDC power are connected, the AC power is used and no current is drawn from the DC supply. 100V Note: The unit will not charge the battery, so you should have a dedicated charging system. Note also, that when running on DC power, the output is lower than when running on AC power. 28. AC Power The CAM160 and CAM80 are fitted with a detachable IEC socket for AC input. Each unit is fitted with a universal power supply, allowing it to operate from any AC mains supply from 100 to 240 VAC, 50-60 Hz. A 6-foot U-Ground to IEC power cable is supplied. An integrated, removable, AC input fuse is fitted just below the IEC socket. To remove or inspect the fuse, first unplug the power cord from the AC socket. Then use a small screwdriver to gently pry open the rectangular fuse holder and inspect or replace the fuse. Replacement fuses must be of the same rating as the original fuse. Low voltage fuses are located internally. 29. DC Power These terminals allow the amplifier to be powered using 24 VDC emergency power supplies. The unit will automatically switch to external DC battery power if your local AC power fails. You will need to connect an external 24 Volt battery to the DC battery terminals. 24 VDC Make absolutely sure the positive post of your battery connects to the positive terminal, and the negative post connects to the negative terminal. To minimize the voltage drop across the wires and prevent overheating, use at least 14 AWG insulated wire. CAM160 / CAM80 – 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 and bottom 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. If the amplifier should overheat, a thermal switch turns off the power amplifier, allowing the heatsinks to cool down. Once the amplifier has cooled to a safe operating temperature, the thermal switch resets and reactivates the amplifier. If this should occur, identify the cause of the problem and take corrective action. For example: • Provide better ventilation, • Install a fan in the rack to move more air, 1/4" TRS Phone Plugs and Jacks “TRS” stands for Tip-Ring-Sleeve, the three connections available on a stereo 1/4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals and stereo headphones: RING SLEEVE SLEEVE RING TIP TIP RING TIP SLEEVE 1/4" TRS Balanced Mono wiring: Sleeve = Shield Tip = Hot (+) Ring = Cold (–) 1/4" TS Phone Plugs and Jacks “TS” stands for Tip-Sleeve, the two connections available on a mono 1/4" phone jack or plug. They are used for unbalanced signals. SLEEVE • Make sure the amplifier is not overloaded with too low of a load impedance or by a short circuit on the speaker line. SLEEVE TIP TIP TIP SLEEVE RACK MOUNTING The front panel rack holes allows the unit to be fitted within a standard 19" rack. The unit still needs to be supported underneath, due to the weight of the power and output transformers. 6. CONNECTIONS Inputs 1 and 2 use a dual-purpose input connector which can accept XLR and 1/4" TRS and TS plugs. 1/4" TS Unbalanced Wiring: Sleeve = Shield Tip = Hot (+) RCA Plugs and Jacks RCA-type plugs (also known as phono plugs) and jacks are often used in home stereo and video equipment and in many other applications. They are unbalanced and electrically equivalent to a 1/4" TS phone plug. SLEEVE TIP SLEEVE TIP The AUX 1 and 2 inputs use unbalanced RCA connectors, as does the MAIN IN and PREAMP OUT. XLR Connectors Inputs 1 and 2 can accept 3-pin male XLR connectors, wired as follows: 2 SHIELD HOT COLD SHIELD COLD 3 HOT 1 3 Phoenix-type Connectors These connectors use small screws to clamp the wires in place. They can be balanced, using three conductor wiring, or unbalanced using two-conductor wiring and a small wiring link joining the ground and negative connector. 1 3 RCA Unbalanced Wiring: Sleeve = Shield Tip = Hot 1 2 SHIELD COLD 2 HOT 1 2 3 1 2 3 XLR Balanced Wiring Pin 1 = Shield Pin 2 = Hot (+) Pin 3 = Cold (–) 10 – CAM160 / CAM80 Balanced Unbalanced AC Line 70V Loudspeakers Backup Battery 24 VDC Graphic Equalizer in pre-out/main-in loop AM/FM Tuner or CD Player AM/FM Tuner or CD Player Paging Priority Switch Chime Switch Telephone Console 7.
