Summary

FEATURES

Audiophile Design

Highlights sophisticated design and premium internal components for superior sound quality and reliability.

Advanced Protection

Each channel is individually protected; only affected channels shut down during faults, others continue playing.

Flexible Input Selection

Assigns a variety of source inputs to each of the 12 channels for custom audio installations.

Bridging

Combines adjacent channels to provide extra power for a single mono channel.

Individual Channel Level Adjustments

Allows independent adjustment of each channel's output level for balanced room audio.

InstaLLock™ Connector Outputs

Simplifies speaker connections using optional, separately purchased InstaLLock™ connectors.

Multiple Power Modes and Output Trigger

Offers constant, trigger, and audio sense modes for seamless integration and external device activation.

SYSTEM DESIGN & OPERATION CONSIDERATIONS

Multi-Room

A system design playing the same source simultaneously in all rooms, with synchronized changes across locations.

Multi-Zone

A system design allowing different sources to be played independently in each room or zone.

Bridging

Describes combining two channels to create a single mono channel for increased volume in specific areas.

Source

Defines a source as any component providing an audio signal, such as CD players or tuners.

Channel

Explains a channel as a distinct amplifier unit providing output to one speaker.

Level Controls

Allows independent adjustment of each channel's output level to balance volume across different areas.

BUS*AUX*LINE Switch

Enables each channel to play inputs from the BUS, AUX, or its own LINE input.

R R+L L Switch

Selects the left, right, or combined left/right audio signal for channels using BUS or AUX inputs.

Bus Input

Allows a single source signal to be distributed to multiple channels on the amplifier.

Auxiliary Inputs

Permits a secondary source signal to be distributed to any of the amplifier's channels.

Impedance Switch

Allows selection between 8Ω or 4Ω to optimize amplifier performance with various speaker loads.

Power Mode Selection

Details three methods (Constant, Trigger, Audio Sense) for turning the amplifier on and off.

SYSTEM DESIGN EXAMPLES

Multi-Room Installation Example

Illustrates distributing audio throughout a home, where all speakers receive the same audio signal.

Multi-Zone Example #1

Shows providing an independent audio signal to one area using a separate source.

Multi-Zone Example #2

Demonstrates listening to different audio signals in each zone, relying on multi-zone preamplifiers.

Home Theater / Multi-Room Example

Explains accessing home theater receiver sources for use in a multi-room installation.

INSTALLATION

Installation Considerations

Guidelines on proper placement, ventilation, and avoiding heat or moisture for optimal amplifier performance.

Select the Power Mode Selection

Guides on selecting Constant, Trigger, or Audio Sense modes for amplifier power-up.

Selecting Inputs

Details how to select sources (BUS, AUX, LINE) and stereo signals (L, R, R+L) for each channel.

Selecting Bridge Mode

Explains how to combine two adjacent channels for increased mono power output to a single speaker.

Select the Impedance Setting

Instructions on setting the impedance switch to 8Ω or 4Ω based on speaker load requirements.

Control Output

Describes the 12V output for triggering external devices when the amplifier is active.

Connecting Speaker Wires

Explains using standard binding posts or optional InstaLLock™ connectors for speaker connections.

Connecting Line Level Audio Inputs

Details connecting sources via BUS, AUX, or LINE IN inputs for optimal system integration.

AC Power

Instructions for connecting the amplifier to a power source and avoiding switched outlets.

OPERATION

Power Switch

Explains the function of the front panel power switch for complete amplifier shut-off.

Active LED

Indicates when the amplifier is powered on and operational.

Protection LEDs

Alerts users to faults in wiring, speakers, or the amplifier causing channel shutdowns.

Level Adjustment Knobs

Allows independent adjustment of each channel's output level for balancing system audio.

TROUBLESHOOTING

No Sound on All Channels

Addresses issues like incorrect cable connections, bad cables, or blown internal fuses.

No Sound on Some Channels

Covers incorrect input selection, bridging switch issues, or speaker connection problems.

Hum or Buzzing Sound

Discusses potential causes like ground loops, AC power issues, or faulty cables.

Amplifier Will Not Turn On

Troubleshooting steps for power outlet issues, the power switch, and incorrect Power Mode settings.
