AER Compact 60 IV Ont

A "Compact" format by AER, designed for stage and precision

The Compact 60/4 embodies the AER spirit: offering an amplifier dedicated to demanding musicians who want to retain the natural character of their acoustic instrument and vocal clarity both on stage and in rehearsal. The idea is clear: a easy-to-transport unit, immediately operational, that maintains professional-level sound quality capable of convincing both audiences and sound engineers. Its all-in-one philosophy aims for practicality without compromising on definition, dynamics, and signal cleanliness.

Who is the Compact 60/4 for, and in what contexts does it make a difference?

This amp is tailored for acoustic guitarists, singer-songwriters, acoustic duos, as well as instrumentalists (ukulele, mandolin, violin with pickup, etc.) seeking faithful and musical amplification. Thanks to its two inputs and output options, it adapts very well to café-concert gigs, small stages, high-end rehearsals, and home studio work when an inspiring sound is desired without heavy setup.

Its compact size and light weight also make it a relevant choice for traveling musicians (public transport, sessions, lessons), while maintaining enough headroom to remain clear in an acoustic mix. And although it was "born" for acoustic instruments, it can also serve as a clean amplification solution for other sources, including some electric instruments depending on the desired sound.

Two channels, dedicated EQ, integrated effects: a setup designed for playing, not tweaking

The Compact 60/4 offers a simple-to-understand architecture but is very comprehensive in practice. Channel 1 accepts an instrument via a high-impedance input, with gain control, high/low attenuation (useful for adapting to different output levels), and a 9 V phantom power supply useful for certain preamps/pickups. Channel 2 is designed for vocals or line sources, featuring a balanced combo XLR / 6.35mm Jack input, with 48 V phantom power for microphones requiring power and dedicated gain control.

Regarding equalization, there is a 3-band EQ on channel 1 and a 2-band EQ on channel 2: a coherent choice to quickly shape a precise instrument sound while maintaining effective voice correction. The "Color" filter acts as a musical voicing of the "mid-cut / treble-boost" type: ideal for opening up a sound, adding brightness, or giving a more "hi-fi" feel without multiplying controls. Finally, the built-in digital effects processor offers 4 presets (2 reverbs, a delay, a chorus), with the possibility to integrate an external effect via a send/return effects loop and control activation by footswitch depending on the configuration.

Sound Character

The Compact 60/4 aims for a natural reproduction, with clear attack and a great sense of detail: exactly what one expects from a professional acoustic instrument amp. Its amplification is designed to remain clean and stable at high volume, limiting distortion thanks to dynamic range control. The result: a sound that retains definition in the upper spectrum, balanced presence in the mids (with the option to open the tone via the "Color" mode), and controlled lows to avoid "boom" effects in reverberant rooms.

The 8-inch (200 mm) dual-cone speaker contributes to this approach: direct projection, articulate response, and excellent vocal intelligibility. In clean mode, the amp highlights right-hand dynamics and instrument nuances. With a piezo pickup, the EQ and "Color" filter help enhance musicality and control any harshness in the treble. With a microphone, you get a precise voice easily integrated into an acoustic mix, particularly effective for solo or duo performances.
