C INPUT/OUTPUT
1 INPUT
GLOBAL INPUTS
• There are two Global Inputs - Global A and Global B. Global A (Global
Interrupt A) and/or Global B (Global Interrupt B) can be toggled ON
or OFF in the Zones menu. All four Zones offer the option to enable
Global Interrupt A and/or B, which, when activated, will take priority and
override all other active line inputs within the selected zone(s).
• GLOBAL A takes priority over GLOBAL B.
• Global A or B input will override any active line. Once Global A or B
input stops receiving audio signal, the amplifier will automatically revert
to the previous input source.
a NAME
• Rename GLOBAL A and/or GLOBAL B by entering preferred name or
identification in the input field.
OPERATION
ENGLISH
11
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
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.
• 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
The CI 8-120 DSP 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 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’s default configuration. Inputs 1–5 should be used for a
5.1 system, and Inputs 1–7 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
12
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.
E DSP
DSP CONFIGURATION AND OPTIMIZATION
The amplifier’s DSP capabilities allow the installer to fine-tune the audio
system to address acoustic anomalies caused by the room environment or
to optimize speaker performance.
DSP Setup Procedure
1 Select Output Channel
Begin by selecting the output channel to which the DSP filter will be applied.
2 Check Existing DSP Preset
The interface will display if a DSP preset has already been assigned to
the selected channel.
3 Enable Test Tone
Activate the test tone for the selected output channel. Use the Type
option to choose between the internal pink noise generator or an
external signal source. Adjust the Volume so the internal test tone is
approximately 30–40 dB above the ambient noise level in the room.
4 Measure Frequency Response
Use a spectrum analyzer (not supplied) to measure the speaker’s
frequency response in the room.
5 Create a New DSP Prole
Under Parametric EQ, select a preset from the drop-down menu to
begin editing. Preset selection is required before adjustments can be
made. Assign a name to the preset—such as the speaker model or room
location—for easy reference.
6 Apply EQ Adjustments
Make the necessary adjustments to the EQ parameters as required by
the measurement results.
7 Activate New Prole
Return to the DSP Preset section and select the newly created profile for
the active channel.
8 Repeat for Other Channels
Proceed to the next output channel and repeat the process.
NOTES
• DSP presets can be saved and exported for use on other ampliers or
imported from previously created congurations.
• To apply the same DSP settings to other channels or presets, the
Duplicate function can be used to copy a prole to another preset.
1 CHANNEL SETTINGS
OUTPUT CHANNEL, DSP PRESET
• Assign a DSP Preset (Preset 1-9) to each Output Channel (Output 1-8) as
desired.
• Ensure the selected DSP Preset has been properly configured and
saved beforehand.
2 TEST SIGNAL
A test signal can be sampled or loaded through all the channels.
This is useful for checking audio level of each channel or comparing/
balancing audio levels among the channels.
a TEST SIGNAL
• On: Activate the test signal for the selected output channel.
• O: Deactivate the test signal for the selected output channel.
b TYPE
• The test signal can be a pink noise generator or actual input
signal from any of the line input channels.
• Select from the drop-down list Pink Noise or Input 1 to Input 8
to serve as test signal for the specific output channel.
• Pink noise is useful in setting up audio and equalization levels.
OPERATION
ENGLISH
13
c VOLUME
• Drag the slider icon to adjust the test signal audio level within a
±12dB range.
• Alternatively, the desired test signal audio level can also be
entered directly in the input field next to the slider icon.
3 PARAMETRIC EQ
Parametric equalization (EQ) is a highly flexible type of audio filtering
that allows precise control over individual frequency bands.
a PRESET SELECTION AND CONFIGURATION
Under Parametric EQ tab, select a preset from the drop-down list (Preset
1–9).
i. Choose the preset number to either configure new settings or recall
previously saved parameters.
ii. Configure the following parameters to be stored in the selected
preset (e.g., Preset 1):
• Master Gain
• HPF, Band 1-5, LPF
• Slope
• Gain
• Frequency
• Q
• Delay
• Peak Limiter
• RMS Limiter
• Tilt Control
• Phase
MASTER GAIN
• Adjusting the Master Gain affects all output channels
simultaneously. This ensures uniform gain control across all output
channels.
• Drag the slider to adjust the level within a ±12 dB range.
• The numerical value of the adjusted gain level is displayed next to
the slider.
• Alternatively, the desired gain level can also be entered directly in
the input field next to the slider icon.
HPF, BAND 1-5, LPF
• Select o icon beside HPF, Band 1-5 or LPF to enable particular band
and configure the parameters.
SLOPE
• Slope refers to how abruptly frequencies are attenuated by the filter
once the cutoff frequency is passed. Slope is quantified in decibels
per octave (dB/octave). Available selectable filter (roll off) slope
values are 6 dB, 12 dB, 18 dB and 24 dB per octave.
GAIN
• Adjust the amplitude (boost or cut) of the selected frequency. Gain
level can be adjusted to ±10 dB.
FREQUENCY
• Set the frequency level where applicable configured parameters
will be enabled.
Q
• “Q” setting refers to the depth the bandwidth can be adjusted. Q
level is from 0.1 up to 24. Bandwidth is wider at lower Q level and
narrower with higher Q level.
DELAY
• Delay can be used on output channels to improve time alignment
between multiple speakers, compensating for varying speaker
distances to the listening area.
• This can be set by measuring the distance from the speaker to the
main listening area and entering values in feet or meters. Value can
also be entered in milliseconds.
PEAK LIMITER
• Peak Limiter reduces the amplitude of the loudest peaks of an audio
signal to protect speakers and amplifiers from potential damage. It
can be used to avoid clipping or distortion.
RMS LIMITER
• RMS Limiter is an additional layer of protection for speakers
connected to the output channel by matching the long term
power of the amplifier to that of the speakers.
TILT CONTROL
• Tilt control can be used to make adjustments to the overall tonal
balance of an output channel by boosting or cutting high or low
frequencies.
PHASE CONTROL
• Phase control can be used to correct time alignment issues
between a subwoofer and speaker channels which maybe caused
by the subwoofer position in the room.
