I. Critical Safety & Maintenance
Q: What should I know about electrical hazards and servicing?
The lightning flash symbol indicates uninsulated “dangerous voltage” inside the unit that may cause electric shock. Do not remove the cover or back panel; there are no user-serviceable parts inside. All servicing must be done by qualified service personnel. Replace fuses only with the same amperage and voltage type, and always re-fit the fuse cover.
Q: Does the front panel power button fully disconnect the amplifier from AC power?
No. The front panel button puts the amplifier into standby mode. To fully disconnect the unit, unplug the power cord. Unplug the unit during lightning storms or when unused for long periods. Always ensure the power cord is easily accessible.
Q: How should I handle ventilation and placement?
The unit may become hot during operation. Always provide adequate ventilation and do not place near heat sources. Do not block vents or cover the unit with objects like newspapers, tablecloths, or curtains. Closed-front cabinet installations are not recommended unless a fan is installed. Do not expose the unit to rain or moisture, and do not place liquid-filled objects on top.
II. Installation & Connection
Q: What are the power and input requirements?
The MCA Series amplifiers are not auto-voltage. Connect only to the correct AC mains:
120 V version: 108–132 V at 60 Hz
220–240 V version: 198–264 V at 50/60 Hz
Always match the wide blade of the plug to the wide slot and fully insert. Balanced XLR inputs are recommended for best signal quality over long cables; RCA outputs can be used if XLR is unavailable. Avoid “RCA-compatible” connectors with hollow center pins and tip holes, as they can damage the amplifier’s RCA jacks.
Q: How should I connect speakers safely?
Always turn off the amplifier before connecting or disconnecting speakers. Use speakers rated for the amplifier’s output to avoid fire hazards. Connect red (+) speaker wire to the red (+) binding post and black (–) to black (–). Use cable rated for maximum output and do not overtighten binding posts.
III. Operation & Troubleshooting
Q: How do the amplifier On modes work?
The rear panel 3-way switch controls amplifier activation:
Manual-On: Use the front panel power button.
Trigger-On: Use a 5–24 VDC trigger signal via the 3.5 mm IN jack; signal can pass to other units via OUT.
Auto-On: The amplifier turns on when it senses an input signal and turns off approximately 20 minutes after the signal stops.
Q: What do the Power Button LED codes mean?
LED Status | Meaning | Action / Likely Cause |
Rapid flashing blue (< 1 sec) | Short-circuited channel | Check speaker cables and connectors for shorts. |
Slow flashing blue (> 1 sec) | Thermal protection | Allow amplifier to cool; ensure proper ventilation. Output resumes in several minutes. |
Solid red | Total shutdown | Disconnect all inputs and power cord. Reconnect only power cord and turn on. If red persists, contact support. |
Solid red (MCA 525 GEN 2 only) | Open fuse | Replace rear-panel fuse with correct type. |
In most cases, only the affected channel shuts down and output resumes automatically once the issue is resolved.

V. Warranty
Q: What is the warranty for MCA Series amplifiers?
MCA Series amplifiers have a 5-year warranty in Canada and the USA. The warranty starts on the date of purchase from Anthem or an authorized dealer. Service requires a copy of the sales invoice. Warranty is void if the product is tampered with, modified, damaged by accident, or repaired by non-authorized personnel.
