Cone diameter

Note

When an HDMI IN is assigned to an input selector in “HDMI Input” (35), this input assignment is automatically set to the same HDMI IN. And in addition to the usual inputs (e.g., COAX1, COAX2, etc.), you can also select HDMI inputs.

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 (such as UP-A1 Dock that seated iPod) to the UNIVERSAL PORT jack, you cannot assign any input to PORT selector.

Some of the settings in this section are set automatically by Audyssey 2EQ® Room Correction and Speaker Setup function (23).

Here you can check the settings made by Audyssey 2EQ Room Correction and Speaker Setup function, or set them manually, which is useful if you change one of the con- nected speakers after using Audyssey 2EQ Room Correc- tion and Speaker Setup function.

This section explains how to specify

which speakers are connected and their sizes. For speakers with a cone diameter

larger than 6-1/2 inches (16 cm), spec- ify Large (full band). For those with a

smaller diameter, specify Small (default crossover 100Hz).

The crossover frequency can be changed in the “Crossover (Crossover Frequency)” (36).

Crossover (Crossover Frequency)

This setting is advantageous for the speakers that you specified as “Small” in the “Sp Config (Speaker Configura- tion)” (36). To get the best bass performance from your speaker system, you need to set the crossover fre- quency according to the size and frequency response of your speakers.

`40Hz, 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz, 200Hz:

Use the diameter of the smallest speaker in your system when choosing the crossover frequency.
