Summary

Safety and Compliance

General Safety Warnings

Provides crucial warnings regarding fire and electric shock risks, emphasizing not to expose the appliance to rain or moisture.

Important Safety Instructions

Environmental Precautions

Advises against using the apparatus near water, to clean with a dry cloth, and to ensure proper ventilation.

Electrical Safety and Servicing

Covers plug safety, power cord protection, using specified accessories, and referring servicing to qualified personnel.

Unpacking and Placement

Setup and Information

Operating Voltage Settings

Amplifier is factory set for specific AC mains voltage; users or dealers cannot change it.

Amplifier Operation

Voltage Protection and Operation

Details protection circuitry for startup, over-voltage, and under-voltage conditions, with LED indicators.

Special Design Features

Robust Protection Circuits

Circuits protect amplifier and speakers from fault conditions like overload, DC offset, voltage, and temperature.

Front Panel Overview

Standby Button and LED Indicator

Toggles amplifier between operate and standby modes; LED indicates status (standby, initialization, operate, out of range).

Rear Panel Connections

Balanced (XLR) Input

Recommended for preserving signal nuances and rejecting noise/interference (EMI/RFI) for superior audio performance.

Single-Ended (RCA) Input

Common analog connection; Classé ensures good performance, but lacks balanced input's interference immunity.

CAN-Bus Control Ports

RJ-45 connectors reserved for future control and communication applications using Classé Audio's CAN-Bus.

High Voltage Danger Warning

Warns of dangerous voltages inside, prohibiting user access for safety; service must be referred to qualified personnel.

Initial Setup Guide

Important Setup Notes

AC mains connection last; power up amplifier last, power down first to prevent transients to loudspeakers.

Step 3: Configure Input Operation

Use Select/Mode buttons to configure balanced or single-ended input operation for each channel.

Step 4: Preamp Connections

Connect preamp using balanced or single-ended cables, ensuring snug connections for optimal signal integrity.

Step 5: Speaker Connections

Connect amplifier output terminals to loudspeakers using high-quality speaker wires, observing correct polarity.

CAN-Bus System Integration

CAN-Bus System Overview

Enables interaction between Delta series components for system-wide status and shared features via touchscreen.

Using CAN-Bus Control

Control via touchscreen of any Delta series component; accessing CAN-Bus via menu, status, and more buttons.

Protection Circuitry Event Log

Records events leading to protection mode activation (overload, temp, voltage, etc.) for diagnostics.

Care and Maintenance

Caution on Liquid Cleaners

Never apply liquid cleaners directly to the amplifier to prevent internal damage to electronic components.

Troubleshooting Common Issues

No Sound, No Channel LED Lit

Checks for power, AC mains issues, fuse, or voltage range problems; suggests microprocessor reset.

No Sound, Channel LED Blinking Red

Addresses protection circuitry activation; guides resetting and identifying upstream faults.

Amplifier Shuts Off Repeatedly

Checks ventilation, ambient temperature, and protection mode sequences for recurring shutdowns.

Blown AC Mains Fuse Procedure

Detailed steps for identifying and replacing the AC mains fuse with correct type and rating.

Standby/Channel LED Flashing Issue

Suggests resetting the unit by disconnecting/reconnecting AC power if both LEDs flash.
