4 Advanced Operation

Sample Rate: Starting from the Attenuation screen, press Menu/Exit to go to the Sample Rate screen. The sample rate of the amplifi er’s DSP is displayed. It can be modifi ed only in System Architect software because all of the FIR fi lter settings will need to be recalculated as a result of the change. Please refer to its Help fi les. When you route a Cobranet input, the sample rate displayed here must match the Cobranet source.

Sample Rate

96 kHz

Modify in software ONLY!

Analog Input Sensitivity: Turn the left Encoder knob to change the Ch. 1 input sensitivity; turn the right Encoder knob to change the Ch. 2 input sensitivity. This screen also displays the amp gain for each channel resulting from the sensitivity settings. See Figure 4.4.

Note: If you do not see the sensitivity you need, try changing the Maximum Analog Input level in the Advanced Menu (described later). This makes different sensitivities available.

To optimize the system gain structure, see Section 3.1 in the I-Tech application Guide at www.crownaudio.com/itech/pdf/137327.pdf.

Presets: A preset is a group of DSP and amplifi er settings for a particular speaker system. Turn an Encoder to view Presets 1 through 50. To recall a preset, press the Encoder, then press and hold the Encoder to confi rm. For more information on presets, see Section 4.3.

The preset currently in use is displayed in the upper right corner.

(A)Active means that the amplifi er is operating exactly according to that preset.

(M)Modified means that the amplifi er is operating according to the preset but with some settings changed.

If a preset number is fl ashing, it is not in use.

In the example shown below,

•Preset 7 is in use (it’s in the upper right corner).

•The amplifi er settings have been modifi ed (M) since Preset 7 was loaded.

•The large “7” is not fl ashing, which means that Preset 7 is in use.

In the example shown below, you turned down an Encoder knob two notches after loading Preset 7.

•Preset 7 is in use (it’s in the upper right corner).

•Preset 7 is active (A). That means the amplifi er is operating exactly according to that preset.

•The large “5” is fl ashing because Preset 5 is not in use.

•Preset 5’s Channel-1 label is “LF–1&2.”

•Preset 5’s Channel-2 label is “LF–3&4.”

Amp Mode: This screen lets you set up the amplifi er for Dual, Input Y or Bridge Mono mode. Turn an Encoder knob to choose among those three options, then press the knob to save your choice. You will be prompted to confi rm your choice. The LCD screen displays the currently selected mode.

In Dual (or Stereo) mode, both channels operate independently.

In Bridge Mono mode, both channels are summed to double the power, and the amplifi er puts out a mono signal.

In Input Y mode, Channel 1’s input signal feeds both channels, and each channel can be set to a different output level, usually for bi-amp operation.

Locate: Allows users to identify a specifi c amplifi er in a large network of amplifi ers without having to compare address information. Locate can be turned on/off from software and/or the front panel. Press an Encoder knob to turn on the Locate function. When on, the LCD screen fl ashes. Press the knob again to turn off the Locate function. In System Architect, the device icon has a blue outline to indicate that it is in Locate mode.
