HT Labs Measures

Five channels driven continuously into 8-ohm loads:
0.1% distortion at 110.8 watts
1% distortion at 134.1 watts

Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 107.5 watts
1% distortion at 127.7 watts

Analog frequency response in Direct mode:
–0.05 dB at 10 Hz
–0.01 dB at 20 Hz
–0.01 dB at 20 kHz
–2.80 dB at 50 kHz

Analog frequency response with stereo signal processing:
–0.09 dB at 10 Hz
–0.03 dB at 20 Hz
–0.07 dB at 20 kHz
–69.90 dB at 50 kHz

This graph shows that the DTR-50.2’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 147.4 watts and 1 percent distortion at 172.4 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 200.4 watts and 1 percent distortion at 259.8 watts.

Response from the multichannel input to the speaker output measures –0.05 decibels at 10 hertz, –0.01 dB at 20 Hz, –0.04 dB at 20 kilohertz, and –2.84 dB at 50 kHz. THD+N from the CD input to the speaker output was less than 0.007 percent at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –75.12 dB left to right and –70.53 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –106.92 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.02 dB at 20 Hz and –0.15 dB at 20 kHz. The center channel measures –0.02 dB at 20 Hz and –0.16 dB at 20 kHz, and the left surround channel measures –0.01 dB at 20 Hz and –0.17 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.08 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 96 Hz and the upper 6-dB down point at 116 Hz.—MJP

Beware of Integra. I have a DTR9.9 that the tuner went out of under warantee. It is currently sent in for repair, but the parts are not available to fix it. I am stuck. They won't respond to phone calls or e-mails. They won't return it. They won't offer me a new or replacement unit. Seems like they are just going to keep it until the rest of the 3 year warantee runs out. I spent about 2600 bucks for this. Integra is supposed to be Onkyo's upper level equipment with premier service.

Update: I finally received repaired receiver. I had to pressure dealer with request for replacement unit if they could not get repair parts. Federal warantee laws would require that. Integra customer service was non existant for me and dealer was only helpful after I threatened legal action.
