The Outlaws’ Guide to the Marantz AV7005
reported by Audyssey to not match the actual speaker placement. We recommend
retaining the Audyssey-measured distances, as they include delays for both physical
distance and for signal processing. For subwoofers with equalization built in, we also
recommend disabling that equalization and using Audyssey alone; in most cases
Audyssey will provide superior results.
The Audyssey MultEQ XT automatic setup process adjusts individual speaker levels,
but these adjustments can also be made manually in the “Channel Level” sub-menu. A
process for doing this using the AV7005’s internal test tones is described on page 58 of
the Marantz AV7005 User Manual. If the Audyssey MultEQ XT automatic calibration is
not used, we recommend performing this manual calibration using an SPL (sound
power level) meter. Analog SPL meters are available at Radio Shack or online for under
$50, while iPhone or Google Android phone owners can purchase SPL meter apps for
as little as $0.99 that provide the same capability.
When any speakers are set to “Small”, the AV7005 will apply bass management to
those speakers and redirect low frequencies to either the subwoofer or “large” front
speakers. The
crossover point
used by this bass management can be adjusted to
coordinate with the speakers in your system. This adjustment is the “Crossover” value
listed in the “Crossover Freq.” sub-menu, which can be set to 40Hz, 60Hz, 80Hz,
100Hz, 120Hz, 150Hz, 200Hz, or 250Hz. This is the crossover point that will be used
with all “small” speakers. If Audyssey Auto Setup has been performed, the “Crossover
Freq.” sub-menu will contain an option for an “Advanced” mode in place of the
“Crossover” mode. In Advanced mode, separate crossover settings can be applied to
the Front, Center, Surround, Surround Back, and Front Height speakers. Each set of
speakers can have a crossover setting of 40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz,
200Hz, or 250Hz. In “Crossover” mode, a single crossover setting is applied to all small
speakers. For either mode, the crossover point should be set higher than the low limit
value (54Hz in the two examples on page 41). We also suggest not setting the
crossover exactly at the speaker’s low frequency roll-off point, particularly for the front
and center speakers. Consider using a crossover point at least 10Hz or 20Hz above the
speakers’ lower limit. When setting all speakers to a common crossover, pick a value
that is at least 10Hz or 20Hz above the front and center speakers’ lower limit. If you are
using speakers that are THX certified, use an 80Hz crossover. This is the THX standard
for speaker certification.
The final setting under
Speaker Setup
is “Front Sp Setup,” which determines whether
the front channels play through the “Front A” and/or “Front B” outputs. The options are
“A,” “B,” and “A+B.” This setting can also be changed using the “SPKR A/B” button on
the remote control. The default setting of “A” is typically recommended.
