ATS vs. AIO Comparison

The Echo ATS is the next-generation successor to the modular Echo AIO platform, integrating the most-used measurement capabilities into a single compact interface.

Side-by-Side Comparison

Spec	Echo ATS	Echo AIO (A / L / S / H)	Advantage
Mic/Line inputs	8	up to 8	Tie
Input dynamic range	115 dB	112 dB	ATS
Input THD+N	−110 dB	< −105 dB	ATS
Input gain	5 steps, 0 → 40 dB (10 dB)	3 steps (1× / 10× / 100×)	ATS
Input coupling	Switchable AC/DC	AC only	ATS
IEPE / CCP	4 mA @ 24 V	4 mA	ATS
TEDS	Yes	Yes (IEEE 1451.4 Cl. 1)	Tie
Line outputs	2	up to 4 (L2)	AIO (count)
Line out max voltage	8 Vrms bal	16 Vrms bal	AIO
Line out dynamic range	120 dB	120 dB	Tie
Line out THD+N	−113 dB	< −102 dB	ATS
Amplifier outputs	4	up to 4	Tie
Amplifier power	10 W peak / 5 W cont.	10 W cont. (8 Ω)	AIO (sustained)
Amplifier dynamic range	108 dB (A-wtd)	100 dB	ATS
Headphone output	3 Vrms, ≥ 16 Ω	3 Vrms, ≥ 16 Ω	Tie
Digital I/O	SPDIF / Word Clock	None	ATS
GPIO	4 in / 4 out	None	ATS
Size	11 × 2 × 8.5 in	17.5 × 8.75 × 1.75 in (1U)	ATS
Power	40 W	60 W	ATS

Bottom Line

The ATS matches or exceeds the AIO on every measurement-quality and connectivity specification. The only specifications where the AIO still leads are higher maximum line-output voltage, higher sustained amplifier power, and more line outputs in a dual-module configuration — none of which involve audio fidelity.
