Using full-range speakers
* Network THRU mode of digital amplifiers RS-A1 and RS- AZ cannot be set up in
the following instances.
-
> If either RS-P1 or RS-P50 is connected to the system.
eae
> If other digital amplifiers in the audio system are connected to the' fletwork filter mode
(other than THRU mode).
When using speakers connected at full range in the system configurations spec-
ified above, set the digital amp to LOW (iow-range) mode and adjust the filter
characteristics using the network menu of the main unit.
> If the speakers are normally used at full range, the network's filter features are not required.
However, to obtain the highest quality sound from the center speaker and subwoofer, the
filter functions of the network are needed.
Therefore, if a center speaker or subwoofer is
incorporated in the system, the digital amplifier cannot be set to the THRU mode, which
bypasses the filter functions.
* When using the speaker at full range with RS-P50 set up in network mode,
switch to LOW output and adjust the filter characteristics.
> The frequency band reproduced in LOW mode (LOW output) can be varied from 25 Hz to 10
kHz by adjusting the filter cutoff frequency. Additionally, adjusting the slope (gradient of
attenuation of the filter characteristics) allows the filter to be set to PASS and enables the
speaker to be used at full range.
Using RS-P50 in NAC mode
« When another audio unit is connected to the optical output of an RS-P50 set up
in NAC mode, the functions governing the timing of audio adjusting become
restricted.
> As RS-P50 enables connection of an analog amplifier, its specifications are somewhat dif-
ferent from those of fully digital equipment.
Therefore, when RCA output (analog signals)
and optical output (digital signals) of an RS-P50 set up in NAC mode are used simultane-
ously, there will be restrictions on the signal delay adjustments under the time alignment
and position fine adjustment functions.
