Atlas Sound AA60G – 4-Input 60W Mixer Amplifier Global Power Supply

Product Overview

The Atlas Sound AA60G is a 4-input, 60-watt mixer amplifier designed for commercial paging, background music, and music-on-hold applications in distributed audio systems. Supporting 70.7V, 100V, and 8-ohm outputs, the AA60G accommodates a broad range of speaker loads and integrates a balanced mic/line input, two stereo RCA line inputs, and a configurable Zone 2 output for secondary zone or MOH routing. The AA60G 4-input mixer amplifier is a practical single-box solution for small to medium commercial audio deployments requiring simultaneous paging and background music capability.

Product Description

The AA60G provides 60 watts of output power at 1 kHz with less than 0.5% THD across 70.7V, 100V, and 8-ohm outputs, covering the full range of common commercial speaker wiring configurations. One balanced XLR/line mic input accepts signals as low as 3 mV and provides 15 VDC phantom power for condenser microphones. Two stereo RCA line inputs (400 mV sensitivity) accommodate CD players, digital music receivers, and streaming devices. A DIP switch-selectable matrix allows any combination of input sources to be assigned to the Zone 2 output, which delivers 1 watt into 600 ohms—the standard requirement for music-on-hold interfaces at telephone system equipment. Priority muting via VOX or an external contact closure switch allows paging announcements to automatically attenuate background music sources. Bass and treble controls on the master output allow basic tonal adjustment without external signal processing. Signal presence LED indicators on each input provide visual confirmation of active sources during operation. The universal AC power supply (100–240VAC, 50/60 Hz) makes the AA60G suitable for use in any region. The unit operates by convection cooling with no fan, reducing noise in occupied spaces. At 8.2 x 3.5 x 11.6 inches and 9.4 lbs, the AA60G is sized for tabletop or optional rack-mounted operation. The optional AAGRMK2 rack mount kit is available separately for 19-inch rack installation.

Key Features

• 60W Output (70.7V / 100V / 8Ω) — Delivers full rated power across all three output configurations, supporting distributed speaker lines and direct-impedance loads.
• Balanced Mic/Line Input with Phantom Power — 15 VDC phantom power supports condenser microphones; input accepts signals from 3 mV for use with dynamic and condenser paging microphones.
• Dual Stereo RCA Music Inputs — Two independent unbalanced stereo line inputs (400 mV sensitivity) accommodate multiple background music sources simultaneously.
• DIP Switch Zone 2 Matrix — Any input or combination of inputs can be routed to the Zone 2/MOH output without additional external routing hardware.
• Priority Muting via VOX or Contact Closure — Paging input automatically mutes background music sources on voice activation or external trigger.
• Bass and Treble Master Output Controls — Front-panel tone controls provide basic frequency adjustment for the main output zone.
• Signal Presence LED Indicators — Per-input LEDs confirm active signal on each channel during operation.
• Universal AC Power Supply — 100–240VAC input supports deployment in any country without power conditioning.
• Convection Cooling — No fan required; reduces ambient noise contribution in occupied spaces.

Typical Applications

• Conference room paging and background music
• Boardroom distributed audio systems
• Commercial meeting space paging
• Multi-purpose room background music
• Training room audio distribution
• Huddle room amplifier with paging
• Music-on-hold for telephone system integration

Frequently Asked Questions

Q: Can the AA60G be rack mounted?

A: The AA60G is a tabletop unit. The optional AAGRMK2 rack mount kit (sold separately) allows it to be installed in a standard 19-inch equipment rack.

Q: How does the Zone 2 / MOH output work?

A: The Zone 2 output delivers 1 watt into 600 ohms, compatible with most music-on-hold telephone system inputs. DIP switches on the unit select which input sources feed the Zone 2 output independently of the main amplifier zone.

Q: Does the AA60G support condenser microphones?

A: Yes. The balanced mic input provides 15 VDC phantom power for condenser microphones. Dynamic microphones are also supported without phantom power.

Q: What outputs does the AA60G provide?

A: The AA60G provides 70.7V, 100V, and 8-ohm speaker outputs. All three output types are available simultaneously from the same amplifier output stage.

Q: How does priority muting work on the AA60G?

A: Priority muting can be activated by VOX (voice-activated) sensing on the mic input or by an external contact closure switch. When triggered, background music sources are attenuated to allow paging announcements to be heard clearly.

Q: What is the warranty on the AA60G?

A: Contact AtlasIED or your authorized reseller for current warranty terms. Standard AtlasIED commercial amplifier limited warranty terms apply.
