2. INTRODUCTION

The CXA160 and CXA80 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 CXA160 has a 160 watt power ampliﬁer, and the CXA80 has 80 watts. Apart from this difference in power output, the two models are identical in details and operation.

The main line-level input is actively balanced, with a sensitivity control and selection switches for enabling the parallel output, a 10 dB pad, and high-pass ﬁltering. The input and priority input have XLR, TRS, screw-terminal and Phoenix euroblock connectors.

The priority input is actively balanced, with a sensitivity control and selection switches for line-level input, mic-level input, mic-level input with 24 VDC phantom power, 10 dB pad, and high-pass ﬁltering.

When an audio signal greater than -20 dB is present at the priority input, or when an external priority switch is pressed, the main input is automatically muted, and the priority input will play.

A parallel output allows the line-level input signal to be daisy-chained to feed other ampliﬁers or parts of your system.

Output modes include 4 ohm constant impedance, and constant voltage 25 V, 70 V and 100 V. The smart output stage is fully protected against permanent damage caused by overloading, shorts, and extreme temperatures.

The universal power supply will operate from 100 VAC to 240 VAC, 50/60Hz, supplied by a detachable IEC power cord.

Rear panel terminals are provided for connecting an external 24 VDC backup battery, with automatic switching if the AC mains fails.

The front panel provides power on/off, a master volume control, and bass and treble controls. Status LEDs indicate signal present, signal overload, fault and power on.

10. Input DIP switch

INPUT CONNECTORS

The Input section has four different styles of input connections for line-level audio signals. Choose one which suits your system the best:

6. Combination XLR/TRS connector. This can accept a male balanced XLR connector, a balanced TRS or unbalanced TS 1/4" connector.

7. 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.

8. Terminal strip. This three-terminal connector accepts the positive, negative and ground terminals of a balanced audio line. Secure the connections with the screws.

Each input style is designed to accept balanced or unbalanced line-level signals. The input can be conﬁgured by means of the DIP-switch (see below).

This three-pole DIP-switch allows you to conﬁgure all four input types, as shown in this table and the details below.

DIP # Purpose DOWN UP

Parallel Enable OFF Enabled

High Pass Filter

3 –10 dB Pad Enable

DIP switch details:

1. Parallel Enable. Select UP if you want there to be an output from the Parallel Output. This allows you to send a line-level copy of the audio input signals to other components or ampliﬁers in your system. Select DOWN if you are not using the Parallel Outputs.

2. 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.

3. 10 dB pad enable. Select UP to reduce the input level by 10 dB.

Enabled OFF

OFF Enabled

9. GAIN pot and OL (overload) LED

This screwdriver-adjustable rotary potentiometer acts as a trim control, and a red indicator LED will light 3 dB before clipping. With normal source material playing, adjust the pot until the LED lights only occasionally during the loudest moments of your program.

15. Priority DIP switch

PRIORITY CONNECTORS

When a signal above –20 dB is detected at the priority input, the main input is muted. This is useful for making announcements, as the music program is then automatically muted. This muting can also be accomplished manually by connecting a user-supplied, normally open, dry contact closure switch to the priority screw terminals.

The Priority input has four different styles of input connections for microphone-level or line-level audio signals. Choose one which suits your system the best:

11. Combination XLR/TRS connector.

13. Terminal strip. The three-terminal connectors labeled +, –, and GND, accept the positive, negative and ground terminals of a balanced audio line. Secure the connections with the screws.

This

This ﬁve-pole DIP-switch allows you to conﬁgure all four priority input types, as shown in this table and described below.

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

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 always 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.

Each priority input style is designed to accept balanced or unbalanced microphone-level, or line-level signals. The priority input can be conﬁgured by means of the DIP-switch (see below).

14. GAIN pot and OL (overload) LED

This screwdriver-adjustable rotary potentiometer acts as a trim control, and a red indicator LED will light 3 dB before clipping. With normal priority source material playing, adjust the pot until the LED lights only occasionally during the loudest moments of your program.

6 – CXA160 / CXA80

5. 10 dB pad enable. Select UP to reduce the input level by 10 dB.

16. Priority Terminals

Priority functions can be initiated by a user-supplied, normally open, dry contact closure switch (or switches) connected to the terminal strip (PRI GND, PRI 1).

Connecting one leg of the switch to the PRI GND screw and the other side to PRI 1 prepares the circuit. Closing the switch actuates the speciﬁc priority, allowing the priority input to play.

PARALLEL OUTPUT CONNECTORS

22 23

These outputs allow you to send a copy of the input signals to another ampliﬁer or component in your system. The output is not affected by the volume or EQ controls.

There will only be an output here if the Input DIP switch Pin 1 is set in the UP position (see page 5 for details).

The output has four different styles of connections. Choose one that suits your system the best:

17. XLR connector. This can accept a female balanced XLR connector.

18. TRS connector. This can accept a balanced TRS or unbalanced TS 1/4" connector.

19. 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.

20. Terminal strip. The three-terminal connectors labeled +, –, and GND, accept the positive, negative and ground terminals of a balanced audio line. Secure the connections with the screws.

21. Low Cut Filter

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.

22. 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.

23. 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 is lit.

CXA160 / CXA80 – 7

26 24

24. 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.

Terminals are provided for 4 ohm low-impedance loads or 25, 70 and 100 Volt high-impedance loads.

All outputs with the exception of the 4 ohm output are transformer isolated.

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).

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 (CXA160: 128 watts, CXA80: 64 watts). For example, for the CXA160, 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: CXA160: 100 watts, CXA80 50 watts.

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.

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.

25. AC Power

The CXA160 and CXA80 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.

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.

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

100V

running on AC power.

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.

26. DC Power

These terminals allow the ampliﬁer to be powered using 24 VDC emergency power supplies.

24 VDC

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.

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.

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,

• Make sure the ampliﬁer is not overloaded with too low of a load impedance or by a short circuit on the speaker line.

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:

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.

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

The Input and Priority Input use a dual-purpose input

connector which can accept XLR and 1/4" TRS and TS plugs.

XLR Connectors

Inputs 1 and 2 can accept 3-pin male XLR connectors, wired as follows:

1/4" TS Unbalanced Wiring: Sleeve = Shield Tip = Hot (+)

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.
