Sony STR-DN1040 AV Receiver Test Bench

Audio Test Bench
This graph shows that the STR-DN1040’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 122.6 watts and 1 percent distortion at 135.9 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 156.4 watts and 1 percent distortion at 180.7 watts.

There was no multichannel input to measure. THD+N from the CD input to the speaker output was less than 0.008 percent at 1 kilohertz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –84.76 decibels left to right and –78.94 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 hertz to 24 kHz with “A” weighting was –106.94 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.06 dB at 20 Hz and –0.38 dB at 20 kHz. The center channel measures –0.06 dB at 20 Hz and –0.45 dB at 20 kHz, and the left surround channel measures –0.05 dB at 20 Hz and –0.41 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.03 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 116 Hz and the upper 6-dB down point at 119 Hz.—MJP

2 channels driven continuously into 8-ohm loads:
0.1% distortion at 122.6 watts
1% distortion at 135.9 watts

5 channels driven continuously into 8-ohm loads:
0.1% distortion at 76.3 watts
1% distortion at 89.3 watts

7 channels driven continuously into 8-ohm loads:
0.1% distortion at 65.3 watts
1% distortion at 82.9 watts

Analog frequency response in Pure Direct mode:
–0.06 dB at 10 Hz
–0.01 dB at 20 Hz
+0.09dB at 20 kHz
–2.40 dB at 50 kHz

Analog frequency response with signal processing:
–0.42 dB at 10 Hz
–0.12 dB at 20 Hz
–0.54 dB at 20 kHz
–57.10 dB at 50 kHz

Video Test Bench
Apart from the capability to upconvert 1080p/24 HD material to UHD (4K), and cross-convert composite and component inputs to HDMI outputs while keeping the source resolution unchanged (neither of these features tested here) the Sony STR-DN1040 does not perform any video processing or upconversion. But it passed our clipping and resolution tests (1080p in/out) with no degradation.—TJN

I don't see a powered second zone in this review. There is no clear answer out there on the web. Does anyone know if this has a powered second zone, allowing different sources to go elsewhere with volume control? I hope so... it has everything else I want! If not, is there a another Sony that does?Thanks.

I am considering buying this receiver to power my bookshelf speakers, which can handle up to 125 watts into 8 ohms. I do not know what is the rating of this into 8 ohms, but I guess it would be too much power for them.
Biamping definitively out of the question.

I am attempting to attach my wii through component to the GAME input. How do I assign the wii audio inputs? I haven't found how to assign audio inputs to match with the component inputs. Only 2 of the Inputs appear to have audio selections that are assignable.

While there is not a second-zone speaker output option per se, there is a "B speaker" option that allows connection of an alternate pair of front left and right speakers. That would still leave the problem of how to control that set of speaker outputs from outside the main zone. But you could certainly start music running on the B speakers and then go to the second zone to listen.
