OPERATION
ENGLISH
b INPUT GAIN · Input Gain refers to the adjustment of the input signal level before it is processed or amplified. Proper input gain ensures the signal is strong enough to maintain quality without introducing distortion or unwanted noise. It sets the foundation for clean and balanced audio by establishing the correct initial signal strength. · If there are inconsistencies with signal sensing, the input gain should be increased. It is recommended to initially set the gain to maximum. If any unwanted noise is introduced, gradually reduce the level until the noise disappears–this represents the optimal gain setting for that source. Input gain can also be used to balance audio levels across multiple sources with varying output levels. · Drag the slider icon to adjust input gain level within ±6 dB range at 0.5 dB increments. The corresponding numerical value of the adjusted input gain level is reflected in the input field next to the slider icon. The desired input gain value can also be entered directly in the same input field.
INPUT 1-8 Configure each Input (1-8) according to name preferences, input gain and sum.
a NAME and INPUT · Configure Name and Input Gain in the same manner as defined under GLOBAL INPUTS.
b 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.
2 OUTPUT
· It is recommended that once all configurations are complete, the installer measures the SPL of each speaker using an SPL meter (not supplied) and makes any necessary adjustments to ensure consistent output levels across all channels.
· Drag the slider icon to adjust gain offset level within ±6 dB range at 0.5 dB increments. The corresponding numerical value of the adjusted gain offset level is reflected in the input field next to the slider icon. The desired gain offset value can also be entered directly in the same input field.
DSP PRESET · Assign a DSP Preset number to a specific OUTPUT channel. Make sure
the selected DSP Preset has been previously configured 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.
D ZONES
NAME · The factory default names of the eight OUTPUT channels are Output 1
through Output 8. · Each OUTPUT channel can be renamed by typing directly over its
default name. For example, replace “Output 1” with a custom name such as “Living Room.” · Each OUTPUT channel corresponds to Speakers 1 to 8 respectively.
INPUT · Each OUTPUT channel can be assigned any of the INPUT channels
(Input 1 – 8). · Select the desired INPUT from the drop-down list to assign a specific
OUTPUT channel to a source INPUT.
GAIN OFFSET · Gain offset can be used to compensate for differences in sound
pressure level (SPL) among speakers in a room, often caused by their placement. For example, a speaker positioned in a corner may produce a higher SPL due to surface reflections compared to one placed in open space. · Additionally, applying DSP to individual speakers can affect the output level of each channel.
The CI 8-120 DSP V2 is divided into four Zones Zone A, Zone B, Zone C and Zone D. These four Zones are defaulted to the following respective Zone Channel and Zone Input.
Zone A · Zone Channel – Output 1, Output 2 · Zone Input Input 1, Input 2 Zone B · Zone Channel – Output 3, Output 4 · Zone Input Input 3, Input 4
Zone C · Zone Channel – Output 5, Output 6 · Zone Input Input 5, Input 6
Zone D · Zone Channel – Output 7, Output 8 · Zone Input Input 7, Input 8
USING CI 8-120 DSP V2 IN A HOME THEATRE SYSTEM · For a standard 5.1 or 7.1 home theatre setup, it is recommended to use
CI 8-120 DSP V2’s default configuration. Inputs 15 should be used for a 5.1 system, and Inputs 17 for a 7.1 system. In this configuration, due to auto-pairing, one channel will remain unused. · To maximize available power in a 5.1 system, configure Line Inputs 1+2, 3+4, and 5+6 to Sum (Mono), and set Outputs 1+2, 3+4, and 5+6 to Bridge Mode to drive the Left, Center, and Right (LCR) channels, delivering up to 135W per channel into 8 ohms. Use Inputs 7 and 8 with Outputs 7 and 8 for the surround channels.

OPERATION
ENGLISH
ZONE NAME · The default factory names of the four Zones are Zone A, Zone B, Zone C
and Zone D. · Each Zone can be renamed by typing directly over its default name. For
example, replace “Zone A” with a custom name such as “Dining Room.”
ZONE OUTPUT · Assign a pair of OUTPUT channels to a Zone. For example, to configure
Zone A, select the desired OUTPUT channel from the drop-down list. When Output 1 is selected, Output 2 is automatically paired and assigned to Zone A. · Each Zone can be assigned from one up to four pairs of OUTPUT channels. However, doing so may limit or completely use up the available OUTPUT channel options for the other Zones. · If the same pair of OUTPUT channels are assigned to a different Zone, they will be removed from their original Zone assignment. – For example, Output 1 and Output 2 are initially assigned to Zone
A, and then select them also for Zone B during configuration. A confirmation prompt will appear. Upon confirming (Yes), Output 1 and Output 2 will be reassigned to Zone B and automatically removed from Zone A.
ZONE INPUT · Assign an Input (1-8) to a Zone. For example, select Input 1 from the
drop-down list as the desired Zone Input for Zone A. · When Input 1 is selected, Input 2 is automatically paired and assigned
to the Output Channels of the Zone being configured. The same applies to Input 3-4, Input 5-6 and Input 7-8. · Changes to the Zone Input are reflected in the Output section of Input/Output menu.
MUTE · Mute or restore audio output of the selected Zone.
GLOBAL INTERRUPT A, GLOBAL INTERRUPT B ON/OFF · When GLOBAL A or GLOBAL B is set to ON, the input connected to the
GLOBAL IN terminal overrides all other active line input channels. · If GLOBAL B is ON and GLOBAL A is OFF, the GLOBAL B input becomes
the active source. · If both GLOBAL A and GLOBAL B are ON, GLOBAL A takes priority and
becomes the active input, overriding GLOBAL B and all other inputs. · GLOBAL A takes priority over GLOBAL B.
ZONE SLEEP · Enable Zone Sleep to automatically switch off the channels assigned
to a Zone when not in use. Sleep duration can be set to 15 seconds, 30 seconds, 1 minute, or disabled (OFF). · When a Zone enters sleep mode, its corresponding Output Channel LED indicators will turn off. · The Zone automatically reactivates and the Output Channel LED indicators illuminate when the connected source becomes active again.
ZONE STATUS · Indicates the Zone is active or inactive. For example, if Zone A goes to
Zone Sleep mode after 15 seconds, Zone Status is OFF. When Zone A becomes active again, Zone Status is ON.
