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 or digital input. 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.

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 1-12: Configure each Input (1-12) 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

• The CI 8-150 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 - Line 1, Line 2
• Zone B: Zone Channel - Output 3, Output 4; Zone Input - Line 3, Line 4
• Zone C: Zone Channel - Output 5, Output 6; Zone Input - Line 5, Line 6
• Zone D: Zone Channel - Output 7, Output 8; Zone Input - Line 7, Line 8

USING CI 8-150 DSP IN A HOME THEATRE SYSTEM:

• For a standard 5.1 or 7.1 home theatre setup, it is recommended to use CI 8-150 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 280W per channel into 8 ohms. Use Inputs 7 and 8 with Outputs 7 and 8 for the surround channels.

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 a Line input (1-8), Optical 1, Optical 2, Coaxial 1 or Coaxial 2 to a Zone. For example, select Line 1 from the drop-down list as the desired Zone Input for Zone A.
• When Line 1 is selected, Line 2 is automatically paired and assigned to the Output Channels of the Zone being configured. The same applies to Line 3-4, Line 5-6 and Line 7-8.
• If Optical 1 is selected for the Zone being configured, the Output Channels assigned to that Zone will have Optical 1L and Optical 1R as their Zone input. The same applies to Optical 2, Coaxial 1 and Coaxial 2. For example, Coaxial 1 is the selected input for Zone A where the assigned Output Channels are Output 1-2 and Output 3-4. Output 1 will have Coaxial 1L, Output 2 will have Coaxial 1R, Output 3 will have Coaxial 1L and Output 4 will have Coaxial 1R.
• 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 Profile: 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 Profile: 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 amplifiers or imported from previously created configurations.
• To apply the same DSP settings to other channels or presets, the Duplicate function can be used to copy a profile 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. Off: 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 Line1 to Line 8 to serve as test signal for the specific output channel. Pink noise is useful in setting up audio and equalization levels.
• 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 [▲] 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.
