Unpacking and Placement unpacking your amplifier Carefully unpack your power amplifier according to the supplied instructions, and remove all accessories from the carton. Please take care when lifting the amplifier, as it is extremely heavy with weight somewhat concentrated near the front right corner. Important! Keep all packing materials for future transport of your Classé amplifier.
custom installations Drawings are included in this manual to facilitate special installations and custom cabinetry (see the section Dimensions). Contact your Classé dealer for more information. serial number The serial number for your power amplifier is found on the rear of the unit. Please note and record this number on the page entitled Important Safety Instructions for your future reference. operating voltage The operating voltage of your Delta MONO is indicated on the rear of the unit.
Special Design Features highly refined This Classé amplifier utilizes our latest technology, implemented with the circuit design highest quality parts. A combination of careful part selection and circuit layout combined with an extended class A operating area enables superior performance under all conditions. It delivers enormous power into low-impedance loads and achieves extremely low distortion throughout the audio band, most notably maintaining its low-distortion profile even at high frequencies.
1 2 3 Front Panel 1 Standby/ON Button & Status Indicator LED The front panel Standby button will toggle the amplifier between operate, its fully operational state, and a standby mode. (See also Wake on Network). The current state of the amplifier is indicated by the LED status indicator in the Standby button.
Caution! If you see the Standby LED indicator blinking red, please check that all external connections are cleanly made and secure. If no fault is immediately obvious, try to reset the amplifier by pressing and holding the standby button. If the unit does not reset or continues to enter protection mode, please call your authorized Classé dealer for assistance. 2 ICTunnel™ Air Intake The Intelligent Cooling Tunnel removes heat from the amplifier by pulling cool air through the intake on the front panel.

POUR RÉDUIRE LE RISQUE DE CHOC ÉLECTRIQUE LA FICHE CENTRALE DE LA PRISE DOIT ÊTRE BRANCHÉE POUR MAINTENIR LA MISE À LA TERRE THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.
If you are using your Classé power amplifier with a Classé preamplifier/ processor, you’re all set – just remove the supplied shorting pins (between Pins 1 and 3) from the amplifier’s XLR connector(s), take standard balanced interconnect cables and plug them in. If you are using another brand of preamplifier or processor, please refer to its operating manual to verify that the pin assignments of its output connectors correspond to those of your amplifier.
4 Classé CAN-Bus Control Ports These RJ-45 connectors are reserved for control and communication applications using a Classé implementation of the Controller Area Network (CAN) Bus specification. Refer to the CAN-Bus section located later in this manual for more information. 5 IR Input and Output Your Classé amplifier includes two 1/8th-inch mini mono-jacks in order to support the IR remote controls that are ubiquitous today.
7 Auto Standby / Wake on Network The Delta MONO employs power saving features to ensure that it consumes a minimal amount of power while not in use. Auto Standby will switch the amplifier off if no audio signal is present for approximately 20 minutes (and if a DC trigger isn’t overriding it). The default mode is for the Auto Standby feature to be disabled.* If you want this feature to be enabled, press the button to toggle it on. You will see a green LED through the hole (next to the button) light up.

11 AC Mains Input (AC IN) An IEC standard power cord (supplied) is used with the Delta MONO. Plug the cord into the IEC receptacle on the rear panel, and the other end into a suitable wall outlet. 12 AC Mains Fuse Your Classé power amplifier has an AC mains fuse, accessible on the rear panel.
Installation Your new Classé amplifier is quite simple to set up and enjoy. Please follow the steps outlined below in order to safely set up and use your new amplifier. Important: It is always a good idea to power up your power amplifier(s) last, after everything else has been powered up and has stabilized. . Conversely, it is good practice to power the amplifier(s) down first when shutting down the system, as this prevents any transients from other components from getting through to your loudspeakers. 1.
The Delta MONO utilizes premium quality binding posts that provide an optimum torque feature which ensures the correct pressure or tightness of the connection while preventing damage that can result from overtightening. Secure the speaker cables by tightening the binding posts until you hear the clicks indicating you’ve reached the proper torque for the connection. 5. Double-check all your connections.
CAN-Bus CAN-Bus Classé’s Controller Area Network, or CAN-Bus, allows communication and control between similarly featured Classé components. When the amplifier is connected with other CAN-Bus-equipped Classé components, the different elements in the system are in constant communication, creating a “global” network that delivers system wide status information and shared operational features, all through the preamp/processor’s touchscreen display.
using CAN-Bus CAN-Bus is controlled via the touchscreen of any Classé component that is so equipped. There is no master component, so Classé series systems where two or more units have a touchscreen can be controlled through any of the touchscreens. However, it is probably easiest to start using CAN-Bus through just one. CAN-Bus is accessed by pressing the menu button on the face of the unit or remote, then the status button, followed by the more button (right arrow) in the upper right corner of the screen.
Global Standby By setting all your components to Global Standby you can bring your entire system in and out of standby by pressing the standby button of any unit or remote. All CAN-Bus software updates automatically set the updated unit to Global Standby. If you want a particular unit to be excluded from Global Standby, deselect Global Standby for that unit.
Care and Maintenance To remove dust from the cabinet of your amplifier, use a feather duster or a lint-free soft cloth. To remove dirt and fingerprints, we recommend using a microfibre cloth and static free lens cleaner such as you would use for cleaning a flat panel display. Special care should be taken to gently clean the meter lens to avoid marking it in any way. Caution! DO NOT use paper towels as they may scratch the meter lens surface.
Troubleshooting In general, you should refer any service problems to your Classé dealer. Before contacting your dealer, however, check to see if the problem is listed here. 1. No sound, and Standby LED is not lit. • The amplifier is not plugged into the AC mains, or the AC mains are down (circuit breaker, fuse). • A brown-out or short-term loss of power might require the internal microprocessor to be reset. Unplug the unit for at least 30 seconds and then plug it in again and try powering it up.
4. The AC mains fuse is blown. There is a specific troubleshooting procedure for a blown AC mains fuse, since this rare occurrence sometimes indicates a significant problem. Please use the following steps, in order: a. Disconnect your amplifier from the AC mains, as well as from its input connections and speaker connections, and remove the fuse cover on the rear of the unit. b. Check the fuse for continuity using an ohm meter, where the resistance should be essentially zero ohms.
