Install your MOON 761
Consider the location and environment of the device carefully. Set it upon an open, stable, and flat surface. The device requires sufficient space above and around it to adequately disperse the heat it generates. Maintain a minimum gap of 5 cm (2″) around the sides and 10 cm (4″) above of the unit to enable airflow. When stacking multiple units, install MOON Bridges (sold separately) between them.
The performance of this device will continue to improve during the first 100 hours of listening.

FUSE magazine containing a power supply fuse
Please appreciate that while some users may report improvements in the performance of their audio equipment when original parts are replaced with after market parts, MOON cannot guarantee the proper functioning of its products under such conditions. Our engineers have ensured that the original fuse should protect your device from catching fire due to electrical calamities. All security, quality, and performance testing, as well as standards certification, is performed with specific components, and any modification from the original design may void its warranty.
POWER switch for toggling the device on [I] and off [O] With the power switch on, the unit may be toggled in and out of Standby using the button on the front panel, a remote control, the MiND Controller, or by MOONLink. The unit may require up to a minute to connect to the network. For best performance, the device should remain powered up and may be toggled into Standby when not in use. It should be powered down during extended absences by disconnecting the power cable. Always power on the preamplifier before the power amplifier. Always power off the power amplifier before the preamplifier.

Personalize your MOON 761 MOONLink
MOONLink technology makes MOON products more intelligent.
A single button press can trigger automated behaviours and simultaneously operate multiple devices over a network in a symbiotic MOONLink Group. MOONLink simultaneously toggles Standby and can adjust display brightness for all devices in the Group, while enabling volume control and automatic input selection of specific devices in the Group.
Use the Setup menu on any complementary model from the North Collection to add this unit to a MOONLink Group.
· MOONLink Group permits the customization of a Group. o Name identifies a device within the Group. o Group ID assigns a Group number to a Device. Assigning the same ID to other devices joins them together as a Group. o Status lists information about the device. o Firmware verifies the firmware of the device and updates it when necessary.
· Available Devices lists devices on the network that could be added to a Group. Holding the Standby button on the front panel for two seconds automatically toggles all the devices in the MOONLink Group into Standby.
