Are the EQ settings applied to Zones 2 and 3 as well as the main?

Does anyone else get an unusual level of hiss from zones 2 and 3, even when they're turned off?

Must be an issue with mine. The main channel is dead quiet, but both the second and third zones have what sounds like tape-hiss, even when switched off. Only reason I discovered this issue was attempting to a-b compare a couple sets of speakers. Otherwise Zone 2 is only used to power some crappy in ceiling speakers in another room.

While attempting the a-b comparison and also discovering the annoying hiss, I learned that the eq is indeed applied to both zones 2 and 3 as well as the main.

That has to be a mistake, EQ is designed to compensate for speakers and rooms. The zone outs are designed to drive different speakers in different rooms, having the main EQ applied to them would be very counter productive. Have you eliminated your zone amp(s) as the cause of the hiss? |

Check if you are dealing with cable noise induction- avoid parallel cable runs. Hiss is probably internal.
I would disconnect everything from UMC, run 2 different rca Zone 2 or 3 to amp, to front L/R & test.
Emo-Q is not applied to zones.as AudioHTIT stated.

The hiss is present with nothing connected to any inputs, but it's only present on zones 2 and 3. I'm not using Emo-Q, but there is a clear audible difference when switching between my settings on Manual EQ1, Manual EQ2 and FLAT, when listening on speakers connected to zones 2 and 3. |

Have you eliminated your zone amp(s) as the cause of the hiss? I guess they made a mistake, the manual EQ settings are applied to the other zones. The only amp in the equation is a UPA-700, the hiss follows the inputs from zones 2 and 3, regardless of which channel of the amp they're plugged into. |

That is not what I would expect.
1) Try a system factory reset & test
2) Run the Emo-Q & test.
3) Call Emotiva

Exact same audible hiss from both zone 2 and zone 3. After testing it at my house, he brought it back home and found the exact same results.
Bottom line is the UMC-200 has a really noisy hiss on zones 2 and 3. I guess they had to cut costs somewhere, and they really cheaped out on those circuits.

I used Zones 1 & 2 all the time, no problem. Bummer, I have not seen this complaint before.
Are you using variable Vout with volume control to an amplifier (ie BasX A-300, UPA-2) or fixed line out to a receiver/integrated amp? May want to check that option. Make sure the fixed setting to a receive/integrated amp is about 50% volume. If you have it @ 100%, you could be over driving the input of the zone amplification. (my suspicion) The manual is NOT clear on that.
If it was easy for me to test mine again, I would- too much work to move amps/receivers around & rewire.
Now use DTR-50.4 for zones because it has android app to control and freed up my amplification options.
Wonder if Emo got some bad parts from suppliers, I would call them.

Fixed line out to an UPA-700 (mine) UPA-500 (my brothers) and an old Carver amp produces the exact same result. Zone 1 on both UMC's is almost dead quiet, as it should be (unless the input level is cranked way up). Zones 2 and 3 hiss loudly regardless of input volume level. I find it hard to believe no one else has, or has noticed this issue, but I guess these were mostly used for HT, so zones 2 and 3 typically go unused.
