Connecting and Powering the Device

WARNING: All connections between the Classic Integrated Amplifier and other devices in the system must be made with all devices turned off. Failure to observe this rule may cause damage to the Classic Integrated Amplifier or other equipment.
WARNING: to ensure compliance with European standards for electromagnetic compatibility, use connection cables no longer than 2m, both between the sources and the Classic Integrated Amplifier and between it and the speakers.
Refer to chapter 2, “Back Panel”.
Connect the speaker cables to the output terminals of the Classic Integrated Amplifier.
WARNING: never connect the positive (red) output terminals to ground. This could cause overloading of the final stage and damage to the amplifier.
If you have one, connect a turntable to the Classic Integrated Amplifier’s phono input. Set the phono input operating mode selector to “MM” or “MC” depending on the type of cartridge mounted on the turntable. If you don’t have a turntable, you can connect a high-level source (CD player, streamer, tuner, recorder) to this input by setting the operating mode to “LINE”.
ATTENTION: to avoid switching noises that could damage the amplifier and/or the speakers, operate the phono input operating mode selector when the Classic Integrated Amplifier is turned off.
Connect other sources to the other single-ended inputs and/or, if you have a source with balanced outputs, to the balanced input.
If you want the Classic Integrated Amplifier to be triggered by another device or multi-room controller, connect a mono cable equipped with 3.5mm jack connectors between the trigger input of the Classic Integrated Amplifier and the trigger output of the other device. Similarly, if you need to send the trigger signal to another device, connect a mono cable equipped with 3.5mm jack connectors between the trigger output of the Classic Integrated Amplifier and the trigger input of the other device.
NOTE: The trigger input operates in parallel with the main power switch, so the main power switch must not be operated if you want the trigger to turn the Classic Integrated Amplifier on and off at mains power level. If the Classic Integrated Amplifier’s main power switch is pressed, the trigger will affect the amplifier’s standby state.
Connect the supplied power cable to the Classic Integrated Amplifier’s power socket and to a power outlet.
Operate the front panel power switch or the incoming trigger signal to turn on the Classic Integrated Amplifier.

Cleaning the Appliance

The Classic Integrated Amplifier should be cleaned with a soft, slightly damp cloth. Do not use alcohol or other cleaners to avoid damaging the unit.
Be careful not to let the liquid drip inside the appliance. Dripping of any liquid into the appliance will void the warranty.
Be careful not to scratch the aluminium front panel and not to damage the silk-screen printing.

Using the “Pre Out” output

The Classic Integrated Amplifier delivers a minimum power of 60Wrms per channel into 8 Ohm speakers and 100Wrms per channel into 4 Ohm speakers. In addition, its dynamic performance (short-term power output) allows it to deliver up to 150Wrms into 8 Ohms and 240Wrms into 4 Ohms. This is sufficient for realistic listening in an average-sized room with medium- or high-range speakers. high efficiency. On the other hand, installations with low efficiency diffusers, especially in large rooms furnished with curtains, rugs or carpets, may require higher powers.
For this purpose, the Classic Integrated Amplifier is equipped with an output that makes the internal preamplifier signal available to drive an external power amplifier with greater power than the integrated one. When using this option, the speakers are connected to the external amplifier. The integrated power amplifier of the Classic Integrated Amplifier remains active but, as it is not loaded by speakers, it does not consume power and does not heat up.
Another way in which the “Pre Out” output can be used is for passive bi- amplification of the speakers if they have separate input terminals for the high and low channels. In this configuration, a second power amplifier is driven by the “pre out” output of the Classic Integrated Amplifier and each pair of terminals of each speaker is connected to the output of the same channel of each power amplifier. Generally, if the external amplifier is more powerful than the one integrated into the Classic Integrated Amplifier, the low way terminals of the speakers will be connected to it, while the high way terminals will be connected to the one integrated into the Classic Integrated Amplifier. Vice versa if the external amplifier is less powerful than the integrated one. If you use the Classic Power Amplifier, which is structurally the same as the power amplifier integrated in the Classic Integrated Amplifier, it is still advisable to have the former drive the low ways of the speakers.

Trigger
The Classic Integrated Amplifier accepts 12VDC trigger signals. It is possible to use a trigger signal to automatically activate the Classic Integrated Amplifier by another device (a source or a multi-room or home automation controller), so that the entire system is turned on and off via the control of turning on the object that generates the trigger signal.
The trigger signal operates a relay placed in parallel with the main power switch, so the Classic Integrated Amplifier will still be turned on if there is a trigger signal on its input, regardless of whether the main power switch is on or off. less activated.
The only difference in the case in which the main power switch is activated and the trigger signal is applied and then removed is that, when the trigger signal disappears the Classic Integrated Amplifier will go into standby as if the relevant switch had been pressed. button and, when the trigger signal is applied again, it will exit standby.
The Classic Integrated Amplifier is also equipped with a trigger output which makes a 12VDC voltage available to drive the trigger input of another device (for example, the Classic Power Amplifier or another external power amplifier), so that the latter turns on when you turn on the Classic Integrated Amplifier. This voltage is turned on when the Classic Integrated Amplifier is turned on or put out of standby and is turned off when the Classic Integrated Amplifier is turned off or put into standby.

WiFi Interface
The Classic Integrated Amplifier is equipped with a WiFi interface through which you can connect it to your home’s WiFi network to control it via the smartphone app available on iOS and Android platforms. In the event of a lack of local WiFi network, the Classic Integrated Amplifier interface functions as an access point, generating its own network to which the user’s smartphone can connect. This option is active when the device is first turned on and can be recalled at any time by holding down the “MUTING” button when turning it on. Once the smartphone is connected it is possible, when the wifi network is present, to enter the connection data to that network and then order the Classic Integrated Amplifier to reset the interface to connect to the network. Pressing the “STANDBY” button when switching on causes the interface to be reset if it is necessary to connect it to a different network.
When the interface is not used it can be deactivated using the appropriate switch located near it on the rear panel.

Precautions for Use
Please pay close attention to the following instructions to safeguard the appliance and for the safety of those who use it.
Never short-circuit the red terminals of the speakers together or with the black terminals: it is very likely that in this way the fuses protecting the final stage will blow or that the final transistors will be damaged.
Never turn the volume knob to maximum when listening to music if speakers are not connected or when listening with headphones, or when a 3.5mm to 6.35mm headphone jack adapter is inserted into the headphone jack : maintaining this condition for prolonged periods can damage the final stage.
Never connect the amplifier to a socket with a different voltage than that indicated on the amplifier packaging label: the power supply protection fuses could blow or the amplifier could be damaged.
Never cover the ventilation slots of the amplifier cabinet, as the final stage could overheat. Although the amplifier is protected against overheating, its operation would be prevented by the continuous intervention of the thermal protection.
Do not insert any metal objects into the amplifier through the ventilation slots.
Be careful not to spill liquids inside the amplifier.
After moving the amplifier from a very cold and humid environment to a warmer one (for example, from the trunk of your car to your living room), wait for the amplifier to reach room temperature before turning it on.
If you suspect that one of the internal fuses of the appliance is blown, avoid working on the appliance yourself and contact a qualified technician to replace the fuse and inspect the appliance: very often, the fuses trip following damage more or less visible to the appliance circuits.
