• Anthem and any related party assume no liability for the user’s failure to comply with requirements. 1.2 IN-USE NOTICES • Disconnect the power cord before connecting or disconnecting any components. • Do not remove the top cover. • Do not modify the product. 2. CONNECTIONS AND OPERATION 2.1 INPUT CONNECTIONS Balanced XLR connection offers the highest transmission quality, particularly over long cable lengths, because it rejects noise and hum pickup. Note that if an RCA plug is inserted into the RCA jack, that channel’s XLR input is disabled. If your preamplifier does not have XLR outputs, use the Single-Ended RCA inputs. Do not use ‘RCA-compatible’ connectors that have a hollow center pin with a hole at the tip – inserting them into the MCA amplifier’s RCA jacks can cause internal damage. 2.2 SPEAKER CONNECTIONS Dependingontheleveloftheinputsignal,thevoltageattheoutputscanbehighenoughtocauseelectricshock–besurethatpoweristurnedoffwhenconnectingordisconnectinganything.Aswell,besurethatthespeakersareratedforusewiththisamplifier–anoverdrivenspeakercanposeafirehazard.

When using Trigger mode, leave the front power button in the ‘on’ position. Auto-On: This feature also eliminates the need to manually operate the power button. Auto-On turns the amplifier on whenever it senses an input signal on any channel, and switches off 20 minutes after the input signal stops. The power button on the front panel must be left ‘on’. 2-Color LED: In Manual mode, the LED on the front panel is lit blue when the amplifier is on. In Auto or Trigger mode, the LED is lit red to indicate standby mode, and blue to indicate operate mode. Note: The amplifier is equipped with a thermal shut off feature. If it overheats, the affected channel will remain off until the temperature falls below the shut off threshold. 2.
