Integra DTR-7.8 A/V Receiver

ARTICLE INDEX

Frequency

As to IMD, it was about the same at the pre-out as at the speaker output, i.e., 0.03%.

THD+N vs. Frequency remained at acceptable levels from 10 Hz to 20 kHz, at the pre-out and at the speaker output for both 8 ohms and 4 ohms. At 4 ohms, distortion is a bit higher than at 8 ohms, which is to be expected. This is a new test script for the software (SpectraPlus) that we requested to be developed, and the results depend on the quality of the soundcard. The distortion curve here is approaching the limits of the card. Our Audio Precision test instrument is accurate to a much higher level, but we can't ship that around to the various writers.

The measured frequency response was within 3 dB, 20 Hz - 20 kHz. Obviously, there is a built-in steep roll-off above 23 kHz.

Conclusions

The Integra DTR 7.8 seven-channel A/V receiver has cutting edge features such as HDMI 1.3a, and internal processing of the latest hi-resolution audio codecs. It offers THX Ultra2 certification at an amazingly low price, and most importantly, produces the clean, neutral sound that we’ve come to expect from Integra products. Integra has produced another winner here.
