Marantz SR-18 Follow-up

Being that there were some unanswered issues regarding technical specifications and format compatibility on the SR-18, I took the liberty to call the Marantz Engineering department directly to resolve these matters.

Tabulated below are the measured technical specifications of the Marantz SR-18:

Note1: All measurements above were taken on Audio Precision Model 1.
Note2: Low frequency bandwidth measurements were limited by the Audio Precision to 10Hz.

96KHz / 24 Bit DAC's

The 96KHz/24 bit DAC's may only be utilized in 2-channel mode in spite the fact that these DAC's are supported on all channels. This is a limitation of the format, not the hardware. The same applies for all other companies which support 96KHz / 24 bit audio. In most cases, better audible results may be achieved using the internal 96KHz/24 bit DAC's of the equipped DVD player when listening to 2 channel 96KHz / 24 bit audio. The reason for this is that most DVD players will not pass a 96KHz signal out of the digital output. Those which do may not have a low enough noise floor or pass a jitter resistance free signal to audible benefit from the higher sampling rate.

Subwoofer Distorted Output Concern from Sound & Vision Magazine

The August 1999 issue of Sound & Vision Magazine reviewed the SR-18 favorably but had one concern regarding a slightly distorted subwoofer output. The reason being was when Marantz submitted the SR-18 to Sound & Vision; it was a proto unit, which did not have the hardware updates on the THX controller circuit. According to Marantz Engineering, this problem has since than been resolved and is no longer an issue.
