Surround Processor Reviews

Audio Frequency response at preamp outputs of Dolby Digital decoder: Left (aqua): –0.02 dB @ 20 Hz, –0.13 dB @ 20 kHz. Center (green): –0.02 dB @ 20 Hz, –0.12 dB @ 20 kHz. LFE (purple): Normalized to level @ 40 Hz: +0.68 dB @ 20 Hz, upper –3 dB @ 63 Hz, upper –6 dB @ 76 Hz.

Analog frequency response in Reference Stereo mode:
–0.03 dB at 10 Hz
–0.00 dB at 20 Hz
–0.00 dB at 20 kHz
–0.02 dB at 50 kHz

Analog frequency response with signal processing:
–0.07 dB at 10 Hz
–0.02 dB at 20 Hz
–0.17 dB at 20 kHz
–11.31 dB at 50 kHz

Response from multichannel input to main output: –0.03 dB @ 10 Hz, –0.00 dB @ 20 Hz, –0.00 dB @ 20 kHz, –0.01 dB @ 50 kHz. Analog THD+N: less than 0.001% @ 1 kHz w 100-millivolt input and volume control set to +1.0. Crosstalk w 100-mV input: –103.30 dB left to right, –103.24 dB right to left. Signal-to-noise ratio 2 “A” weighting:–128.04 dBrA.—MJP

Video: The Emotiva outputs the same resolution as the input; that is, it doesn’t upconvert video. That doesn’t necessarily mean that such a pre/pro or AVR won’t compromise the input source; the signal must still pass through the switching circuitry. But the XMC-1 performed perfectly in that regard, with no issues on our clipping, resolution, and 3D pass-through tests.—TJN
