• If GLOBAL A and/or GLOBAL B are turned ON, the source(s) connected to GLOBAL IN terminals will become the active input defeating all other active line input channels.
• With GLOBAL B set to ON and GLOBAL A at OFF setting, GLOBAL B input becomes the active input defeating all other active line input channels. However, if GLOBAL A is set to ON and with GLOBAL B also at ON setting, GLOBAL A input becomes the active input over all other active input channels. GLOBAL A takes priority over GLOBAL B.

NAME

• The factory default names of the eight LINE INPUT channels are Line 1 up to Line 8. Each LINE INPUT channel can be renamed by directly typing over the specific LINE INPUT. For example, type over "Line 1" with the desired name or label like "CD Player".
• The eight INPUT channels correspond to eight individual input sources connected to their respective rear panel LINE INPUT ports.
• The four digital sources with corresponding rear panel digital input ports are named Opt 1, Opt 2, Coax 1 and Coax 2.

INPUT GAIN

• Gain adjustment allows all input sources to play back at the same level so you don't need to adjust the level every time a new input source is selected. The ability to level out the input sources will also eliminate any jolting transitions when switching between input sources. It is generally preferable to reduce the level of the loudest input source rather than making louder the softer input sources.
• Grab the pointer of the INPUT GAIN knob icon and rotate to adjust gain level within ±6 dB range at 0.5 dB increments. The corresponding numerical value of the adjusted input gain level is reflected below the knob icon. You can also type directly desired input gain value in the section below the INPUT GAIN knob icon.

SUM (MONO)

- Two adjacent line input sources are summed up to provide a mono signal output. Set SUM (Mono) to "On" to combine two adjacent line input sources or "Off" to maintain stereo input sources.

OUTPUT SETUP

NAME

• The factory default names of the eight OUTPUT channels are Output 1 up to Output 8. Each OUTPUT channel can be renamed by directly typing over the specific OUTPUT. For example, type over "OUTPUT 1" with the desired name or label like "Living Room".
• The eight OUTPUT channels correspond to the SPEAKERS 1 to 8 respectively.

INPUT

• Each OUTPUT channel can be assigned any of the INPUT channels (Line 1-8, Optical 1-2 and Coaxial 1-2). Assign a particular OUTPUT channel with a source INPUT by selecting preferred line INPUT number from the drop down tab.

GAIN OFFSET

• Gain offset allows output channel levels to be adjusted independently.
• Grab the pointer of the GAIN OFFSET knob icon and rotate to adjust gain level within ±6 dB range at 0.5 dB increments. The corresponding numerical value of adjusted gain offset level is reflected below the knob icon. You can also type directly desired gain offset value in the section below the GAIN OFFSET knob icon.

PRESET

- Designate a DSP Preset number for the particular Output Channel. Ensure that the DSP Preset number you allocate has been previously setup and saved.

BRIDGE MODE

• Combine both adjacent output channels into Mono output by setting "Bridge Mode" to "On". Set "Bridge Mode" to "Off" to maintain stereo output.
• Refer also to item about "SPEAKERS (1-8)" under "IDENTIFICATION OF CONTROLS" for further information and guideline about Bridge Mode.

DSP

PRESETS

OUTPUT CHANNEL/OUTPUT NAME/DSP PRESET

• Output Channel, Output Name and DSP Preset are combination settings that can be modified at the PRESETS section of DSP menu or OUTPUT SETUP in the INPUT/OUTPUT menu.
• Assign an Output Channel with an Output Name that can either be the default name or by typing over desired Output name. Designate a DSP Preset number for the particular Output Channel. Ensure that the DSP Preset number you allocate has been previously setup and saved.
• Any changes in Output Channel, Output Name and DSP Preset settings at the PRESETS section of DSP menu will also be reflected in the OUTPUT SETUP section of INPUT/OUTPUT menu and vice-versa.

SAVE PRESET(S)

SAVE PRESET(S) involve a combination of EDITING, adjusting, setting and saving desired Slope, Q, Frequency and Gain settings. Undertake the following steps to SAVE PRESET(S).
