Integra DHC-40.2 Surround Processor HT Labs Measures

HT Labs Measures

Analog frequency response in Direct mode:
–0.04 dB at 10 Hz
–0.00 dB at 20 Hz
–0.02 dB at 20 kHz
–0.13 dB at 50 kHz

Analog frequency response with signal processing:
–0.06 dB at 10 Hz
–0.01 dB at 20 Hz
–0.09 dB at 20 kHz
–40.45 dB at 50 kHz

The chart below shows the frequency response of the left (aqua), center (green), LFE (purple), and left surround (red) channels at the preamp outputs of the Dolby Digital decoder. The left channel measures –0.01 decibels at 20 hertz and –0.10 dB at 20 kilohertz. The center channel measures –0.00 dB at 20 Hz and –0.07 dB at 20 kHz, and the left surround channel measures –0.01 dB at 20 Hz and –0.08 dB at 20 kHz. The LFE channel, normalized to the level at 40 Hz, is +0.08 dB at 20 Hz, reaches the upper –3-dB point at 96 Hz, and reaches the upper –6-dB point at 116 Hz.

Response from the multichannel input to the main output measures –0.03 dB at 10 Hz, –0.00 dB at 20 Hz, –0.02 dB at 20 kHz, and –0.13 dB at 50 kHz. The analog THD+N is less than 0.006 percent at 1 kHz with a 100-millivolt input and the volume control set to 84. Crosstalk with a 100-mV input was –90.76 dB left to right and –92.50 dB right to left. The signal-to-noise ratio with “A” weighting was –123.20 dBrA.—MJP

In looking at the photo of the back panel of this receiver, I am a bit confused. I know I'm not in the same league as your reviewers, but, where are the speaker connections? Please respond, as I won't get any rest this weekend until I have an answer!

Thanks

The DHC-40.2 is not a receiver. It's a preamp/processor. It is designed to be connected to a power amplifier, which provides the speaker connections you are wondering about. The unit is very similar to a reciever, except for the fact that it does not include an amplifier for powering speakers. It only processes the audio and video signals.

There might be less confusion to new investigators if you would have mentioned the type of amplifier you were running the Integra through.
