21. AMC+60, AMC+120, AMC+250 - Danger de voltage. Aﬁn d’assurer un bon fonctionnement utiliser un câble de catégorie 3.

22. Assurez-vous que l’appareil est hors tension avant de connecter les hauts parleurs. Veriﬁez que la sortie des enceintes soit protégées contre un contact physique. Respecter les polarités des terminaux ainsi que le câblage des enceintes pendant le fonctionnement aﬁn d’assurer une utilisation sécurisee.

Pour indiquer les risques résultant de tensions dangereuses.

INTRODUCTION AND CONTENTS

AMC+ SERIES

The Australian Monitor AMC+ series of ampliﬁers takes the heritage and reliability of our famous AMIS series ampliﬁers and integrates these features into low cost ampliﬁers for applications where reliability is everything, but the more elaborate features of our AMIS series are not required.

Available in 30, 60, 120 and 250 watt versions, the AMC+ series are 2 RU mixer ampliﬁers, featuring 70/100 volt line and 4 ohm outputs, and 4 universal mic/line inputs.

Master volume and overall treble and bass controls are provided, along with Vox triggered muting (defeatable), giving channel 1 priority over inputs 2, 3 and 4. There is also the facility to add a tone generator card.

The Australian Monitor AMC+ series gives the contractor a low cost alternative in applications that are price sensitive, but still require a high quality of sound reproduction and reliability.

Each channel input section has two inputs: XLR input – This is a balanced microphone input. It has an input sensitivity of 1mV. RCA input – This is an unbalanced line level input. It has an input sensitivity of 150mV. The two RCA sockets are summed to mono internally.

REC Output

The REC output is on unbalanced RCA connectors. The output level is 150mV into 10kohm at rated output. The output is dual mono. The REC output is not affected by the MASTER volume control or the BASS and TREBLE controls. The REC output does not receive the tone signal if the optional tone generator module is installed.

Line Output

The LINE output is on a balanced XLR connector. The output level is 0.775V into 1k at rated output.

Note: When wiring the LINE output as unbalanced, Pin2 should be wired as hot and Pin1 should be wired as ground/ shield. Do not wire Pin3.

Direct Out

Speaker connections are provided on screw terminals. 4 ohm low impedance, 70V and 100V line outputs are provided.

Mains Voltage Selector

The operating voltage of the ampliﬁer is user selectable between for 115V or 230V operation via a slide switch located above the AC mains inlet. This switch should be set to match the AC voltage of your country.

Failure to set the Mains Voltage Selector correctly prior

to use will result in catastrophic failure.

115V operation 1A 3.15A 4A 8A

Always replace the fuse with one of the same value and type.

Always disconnect power to the ampliﬁer before replacing fuses.

(Optional) Tone Module

These terminals are for use with an optional tone module (not supplied). Use Australian Monitor ATC5488 module.

Phantom Power

12V phantom power is available for condenser or electret microphones on the XLR input when this switch is pushed in.
