Emotiva UPA-2power ampfeedsApogee Acoustics Stagespeaker
Used together in 2 systems. The Apogee Acoustics Stage is in 4.
Not recommended
We would not pair the Emotiva UPA-2 with the Apogee Acoustics Stage — the issues below are hard to live with.
What the compatibility check found
Speaker impedance (3Ω) is below amplifier's minimum rating (4Ω). Risk of amplifier damage.
IssueWhy
Impedance Matching
Use speakers with higher impedance or an amplifier rated for lower impedance loads. Never use speakers below the amplifier's minimum rated impedance.
Nothing here sets the volume. A power amp needs a preamp, or a DAC or streamer with its own volume control, before it makes sound.
