Requirements
Before connecting to AC mains power, make sure that the mechanical installation, cooling requirements, wiring, and controls are all set to the configuration needed for your application. Failure to do so could result in damage to the unit or to other components in the system.
AC Mains
This amplifier uses a universal Switch Mode Power Supply (SMPS) with active Power Factor Correction (PFC). The power supply will autodetect nominal AC mains voltage from 100 to 240VAC, 50-60Hz.Use only the provided AC cord to connect to AC mains.
All CA models have a fixed, non-defeatable warm-up delay of two seconds to protect against excessive in-rush current when first powered up. The model number and power consumption are indicated on the back panel label placed near the AC inlet. To reduce the risk of ground loop hum, all sound system ground references should originate at the same AC power distribution point. Do not lift or remove the amplifier power cord ground pin.
Input Signal Wire
Use shielded wiring for balanced or unbalanced audio signals. Shielding which is properly grounded will protect the signal from outside electrical interference such as RF, fluorescent lighting, and computer/display emissions. Unbalanced or single-ended (tip-sleeve) lines of less than 10 feet are generally ok, but for greater distance or noisy field environments, use balanced input signal wiring.Each channel’s Euroblock, 1/4″ phone jack, and XLR inputs are wired in parallel, with XLR pin 2 (+) and pin 3 (-). When using an unbalanced input, wire the signal to the input (+) Euroblock pin, phone jack tip, or XLR pin 2, and also be sure to wire the input (-) pin, phone jack ring, or XLR pin 3 to ground. Do not leave the (-) input unconnected. Avoid running low level signal wires in close proximity or parallel to long speaker cables, AC power cables, or power transformers, as they can induce hum or oscillation.
Speaker Wire
Note: The sound system installer is responsible for using loudspeaker wiring that is in compliance with local electrical code. The following recommendations for speaker wiring are based on UL 60065 section 5.2-d and the US National Electrical Code Article 725. These are only guidelines, consult your local code for specific up to date requirements.
- Class 2 wiring is typically used when the maximum measured open-circuit speaker output voltage is less than 120V rms.
- Class 3 wiring is typically used if the measured open circuit output voltage exceeds 120V rms, such as when amplifiers are used in bridged mode. See the specifications for specific model configurations that may require Class 3 speaker wiring.
Speaker wire gauge: CA amplifiers are capable of delivering high levels of output current, so the wire gauge used for speaker outputs is important. Inadequate wire gauge, especially over long distance, adds significant resistance to the speaker’s own impedance, reducing the power which is actually delivered to the speaker. It could also result in a decreased damping factor and potential fire hazard. Since power at the speaker load is of primary concern in system design, refer to the table below to best determine appropriate wire gauge for your application.
The following table lists the resistance per 100 feet of common copper wire gauges, and also lists the percentage of the speaker load power which would be lost as heat in an arbitrary 100 ft run of different gauges of 2-conductor copper speaker wire.
|
Wire Gauge |
Ohms /100ft | 8Ω load | 4Ω load |
2Ω load |
|
#8 |
0.0605Ω | 0.8% | 1.5% | 3% |
| #10 | 0.1018Ω | 1.3% | 2.5% |
5% |
|
#12 |
0.1619Ω | 2.0% | 4.0% | 8% |
| #14 | 0.2575Ω | 3.2% | 6.4% |
12.8% |
|
#16 |
0.4094Ω | 5.1% | 10.2% | 20.4% |
| #18 | 0.6510Ω | 8.1% | 16.3% |
32.6% |
This table expresses the power loss as a percentage of the load’s power rather than the total amplifier output power in order to accurately determine power loss at other cable lengths. For example, if you plan to deliver 150 watts to an 8 Ohm load through 50 ft of 14 ga. cable, the power loss in the cable would be half that of a 100 ft run of #14 wire as shown in the table, or 1.6% of 150W, which is an insignificant 2.4 watts. However, if you were to run 200 ft of 18 ga. cable to a 2 Ohm load, the loss would be twice that of the 100 ft run shown in the table, or 65.2% of 250W, which is 163 watts lost as heat. Always be sure to use adequate gauge speaker wire.
Remote Control Wire
- Remote DC level control – Bell or telephone wire is sufficient for DC level control, as well as CAT5 cable. The V+ and Ground pins from one amplifier channel can be shared with other remote DC level controls wired to the same amplifier, however do not connect remote control ground to any external grounds.
- Remote Standby – This is a logic level signal, use low gauge wire, shielding is unnecessary.
Mechanical
Each amplifier model is 2RU and is designed to fit into a 19-inch equipment rack with minimum depth of 16.1″ (409mm). Use four screws when mounting the amplifier to the front rack rails. Rear support is recommended for mobile or touring use. In some installations where the sound system is exposed to a high level of RF noise or system-induced oscillation, it may be necessary to ground the amplifier’s chassis to the rack enclosure. This is accomplished using star type lock washers on the four rack mounting screws, placed between the amplifier chassis and the rack rails. These star washers will penetrate through the amplifier and rack rail finish to adequately ground the chassis to the rack.
Cooling
Air vents on the amplifier front and side panels must have access to free flowing room temperature air. Cool air is drawn in through the sides and blown out the front. It is not necessary to leave empty rack spaces above or below the amplifier. See specifications for amplifier thermal output characteristics in BTU/hr.
Amplifier Protection
Power-On Delay: All models have a two second turn-on delay to prevent excessive in-rush current when first powered on.
Thermal Protection: Cooling fans are continuously variable, reaching their maximum speed when an amplifier channel reaches 80% of it’s safe operating temperature. Temp LEDs turn on when signal limiting countermeasures are being applied to that channel due to over temperature conditions.
Overpower Protection: To protect internal components against overpower conditions, a protection scheme in each output stage reduces audio output power until the fault condition is no longer present.
Output DC and Rail Fault Protection: Output DC on any channel will trigger the Protect LED and mute that channel.
AC Mains: If the AC Mains line voltage exceeds or falls below the specified operating range, the amplifier will temporarily shut down. It will automatically restart as soon as the AC line voltage returns to the specified range.
For details on these and other amplifier protection schemes, plus their LED codes, refer to the troubleshooting section.
Front Panel Features
CA-1.54 shown
4.1 Air Vents
Cool air enters in through the amplifier sides and is vented out the front.
4.2 Channel LED Indicators
- CLIP/MUTE (red):CLIPPING is indicated when the speaker output reaches 95% (-0.5dB) of maximum power.MUTE is indicated when front panel level or DC level controls are fully attenuated.The Clip/Mute LED is also used with the Protect LED to indicate output DC fault. See the troubleshooting section for LED fault codes.
- SIGNAL (green) is indicated when amplifier output voltage reaches 25% (-12dB) of maximum.
- CURRENT (green) indicates when output current delivered to the speaker load is 2 Amp or greater.
- TEMP (yellow) indicates that automatic counter-measures are being applied due to an excessive internal temperature .
4.3 Protect LED
The red protect LED initially turns on to indicate that real-time countermeasures are being applied to overpower, over-temperature, or rail voltage fault conditions while the amp is still running.
If the countermeasures are unsuccessful and the amplifier protects itself by shutting down, the protect LED remains on and the amplifier’s power must be cycled before resuming normal operation.
The exception to this is when the amp shuts down due to the AC mains voltage being out of range, in which case the amp automatically restarts as soon as the AC mains line voltage returns to the specified operating range.
4.4 Disable LED
This yellow LED lights when the power switch and level controls have been disabled using the back panel DIP switch (sec. 5.2b).
4.5 Channel Attenuators
These control the level of the amplifier, and work in combination with the remote DC level controls. When an input attenuator is turned fully off, the red Clip/Mute LED for that channel turns on to indicate mute status. Front panel attenuators and the power switch can be disabled using the back panel DIP switch (sec. 5.2b).
4.6 Bridge LED
This green LED indicates when a channel pair is set to BRIDGE mode from the back panel switch (sec. 5.6). In bridge mode, only the odd numbered input and level control for that channel pair is used.
4.7 Power Switch/LED
This switch is used for powering the amplifier on or off. Its white LED lights solid when the amplifier is on and flashes at 1Hz when in standby mode. The power switch can be disabled using the back panel DIP switch. The three possible power switch LED conditions are:
- Fully lit: The amplifier is powered up, even if the power switch has been disabled, in which case the disable LED will be on.
- Flashing: The amplifier is in standby mode.
- Fully off: The amplifier is completely off.
4.8 Model Number
The first two numbers of model number express the power rating per channel of the amplifier. For example, “1.5” mean 1,500W per channel, “1.0” means 1,000W per channel, and “50” means 500 W per channel. The last number is the channel count.
4.9 Mounting Holes
For mounting to a 19″ equipment rack.
Rear Panel Features
CA-1.54 shown
5.1 Standby Connector
This Euroblock connector is used for remote contact closure control of amplifier standby status, which places the amplifier into a low power consumption state. A DIP switch sets standby circuit polarity.
5.2 Standby Polarity & Front Panel Disable DIP Switch
5.2a Standby Polarity
The Standby Polarity DIP switch sets the polarity requirement for placing the amplifier into standby. When standby polarity is set High, the amp goes into standby whenever the circuit is open. When standby polarity is set Low, the amp goes into standby whenever the circuit is closed.
5.2b Front Panel Disable
The Front Panel Disable DIP switch deactivates all front panel controls.
5.3 DIP Switch Channel Settings
Each channel has its own DIP switch for independently setting 80Hz HiPass Filter, Clip Limiter, and Gain as described below:
5.3a High Pass Filter
An 80Hz 2nd order hipass filter is used to reduce low frequency content going to a speaker.
5.3b Limiter
The clip limiter is used to prevent the amplifier channel from sending clipped audio to the speaker. When the clip limiter is enabled, input signal level is automatically turned down whenever full output power is exceeded.
5.3c Gain
The Amplifier Gain settings are used to set the overall voltage gain of the amplifier in dB. This is useful when matching an amplifier to input signal strength. Using the maximum expected input signal level, set amplifier gain to the highest setting possible without risk of the amplifier going into clipping. The Gain setting of 1.4V means a 1.4V input signal will drive the amp to full output.
5.4 Euroblock Input Jack
Used for wiring a balanced input. Euroblock connectors and 1/4″ TRS/XLR combo jacks are internally wired in parallel. If using an unbalanced signal source on the Euroblock connector, wire its input signal to the (+) pin, shield to (G), and also wire the (-) input pin to ground.
5.5 Remote DC Level Control
Each channel has a potentiometer circuit available on a Euroblock connector for remote DC level control of that channel. The illustration to the right shows proper wiring. There is no limit to wire length. Do not use any other ground source. If multiple remote DC level controls are used for different channels, the same ground and V+ sources can be shared.
5.6 Bridge Mode Switch
This switch, when pressed in, places the adjacent channel pair into bridge mode, combining two amplifier outputs for more power to a single speaker load. Bridge mode uses only the odd numbered input and level control, disabling the even numbered input and level control for that channel pair. Speaker outputs in bridge mode must be wired differently, as shown on the back of the amplifier. A bridge mode switch button can be removed for added security by pulling it straight off.
5.7 Combo Input Jack
The combination 1/4″ TRS and XLR jack (pin 2 hot) is wired in parallel to the Euroblock input. Do not float the TRS ring or XLR pin 3, connect it to (-) signal or to ground (if unbalanced).
5.8 Speaker Output Connectors
7.62mm Euroblock connectors are used for convenient and secure wiring to speaker loads. Bridge mode uses the center two pins as indicated on the amplifier back panel.
5.9 AC Mains Connector
Always use the AC cord provided by Ashly for connecting to mains power. The amplifier autodetects nominal mains voltage from 100VAC to 240VAC. WARNING: Do not remove or lift the mains connector ground.
5.10 Serial Number Sticker
This sticker identifies the product model number, serial number, and AC mains current/ power rating.
