COAX, OPT1, OPT2–Select the digital audio input 
to which the video component has been 
connected.
- - - - -–Select if you are using an analog audio input.
Configuring speakers (Sp Config menu)
This section explains how to specify which speakers 
are connected and defines their sizes.
For speakers with a cone diameter larger than 6.5 
inches (16 cm), specify Large (full band). For those 
with a smaller diameter, specify Small (default 
crossover 120Hz).
The crossover frequency can be changed in the 
Crossover submenu.
Setting the crossover frequency (Crossover Frequency 
submenu of 
Sp Config menu)
This setting is recommended for the speakers that 
you specify as Small. To get the best bass 
performance from your speaker system, you need 
to set the crossover frequency according to the size 
and frequency response of your speakers. Options 
include 40Hz, 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, 
150Hz, 
and 200Hz.
Use the diameter of the smallest speaker in your 
system when choosing the crossover frequency.
Using the Double Bass setting (Double Bass submenu of 
Sp Config menu)
Lets you boost bass output by feeding bass sounds 
from the front left, right, and center channels to the 
subwoofer. Optional settings are On and Off.
Setting speaker distance (Sp Distance menu)
Lets you specify the distance from each speaker to 
the listening position so that the sound from each 
speaker arrives at the listener’s ears as the sound 
designer intended.
Notes
When an HDMI IN is assigned to an input 
selector as explained here, the digital audio 
input for that input selector is automatically set 
to the same HDMI IN. In addition to the usual 
inputs, such as COAX, you can also select HDMI 
inputs.
The available sampling rate for PCM signals 
from a digital input (optical and coaxial) is 
32/44.1/48/88.2/96 kHz/16, 20, 24 bit.
If you connect a component to a UNIVERSAL 
PORT
 jack, you cannot assign any input to the 
PORT selector.
Note
Some of the settings in this section are made 
automatically by the Audyssey 2EQ® Room

Audyssey 2EQ® room correction and speaker setup” 
on page 12.
