Inputs Each input may be personalized.
· Label is the name of the input as it appears on the display. Select a predefined label or manually enter a custom label.
· Offset is a variable amount of gain applied to each input to fine-tune its volume level so that source components connected to all inputs may have similar levels.
· Home Theatre Bypass disables volume control in this device. This mode sets the preamp volume to unity gain for use with a separate audio-video receiver or home theater processor. There is an additional prompt to confirm that a device with its own volume control is connected to the input of the MOON 641 before activating this mode.
· Enable makes an input available to select. It may be disabled to reduce the number of unused inputs to scroll through.
· ARC (Audio Return Channel) HDMI is an audio input for use with a TV. CEC (Consumer Electronic Control) enables multiple devices to share commands–such as Standby and volume– from a single remote control.

CEC Settings
· Audio Only enables audio but disables CEC commands. · Audio + CEC Volume enables audio and CEC volume control but disables other CEC
commands. · Complete enables audio and all CEC commands.

Analog Outputs Each pair of analog outputs may be configured independently as a Variable-volume output for use as a preamplifier or as a Fixed-volume output for use with a device with its own volume control (like an integrated amplifier).

When both pairs of outputs are set to Fixed, volume commands are relayed to the next MOONLink device in the signal chain.

Caution: The fixed volume level is extremely high! Before setting the analog output of this device to Fixed, lower the volume of the preamp or integrated amp to which it is connected.
Multiroom The MiND Controller mobile app includes a feature to join multiple MiND 2 Zones together to play audio as a cohesive system. In addition to streaming audio via the MiND 2, this device may also share audio from any of its inputs with the other multiroom devices.

· Original mode maintains the original signal through this device while digitally sharing a digitized audio signal with other multiroom devices on the network.
· Synchronized mode forces all the multiroom devices to share one synchronized digital audio signal.

Bluetooth Audio Devices may connect to this device to transmit their audio via Bluetooth to play through this device. Before connecting for the first time, the two devices must be paired to each other.

· Pair makes the device visible to nearby devices in pairing mode for up to 30 seconds. · Disconnect an audio source when it should no longer transmit through this device.

Functionality Remote Control This unit may link with up to two BRM-1 remote control units at a time.

· Link Remote searches for a nearby MOON BRM-1 remote control, displaying its unique ID on both devices and permitting them to be associated.
· Unlink Remote displays associated BRM-1 units permitting them to be disassociated from this device. · Information displays useful details about the associated BRM-1 units.

Refer to the separate Guide included with the BRM-1 for more information.

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.

· 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 Reset the name and ID to their default values to remove a device from a Group.

o Firmware verifies the firmware of the selected device and updates it when necessary.

· Available Devices lists devices on the network that could be added to a Group.

· MOONLink with Wi-Fi permits devices to form a MOONLink Group while one device is connected to a wireless

network (Wi-Fi). Since connecting an Ethernet cable to this device normally disables its Wi-Fi connection,

MOONLink with Wi-Fi enables the device to remain simultaneously connected to a Wi-Fi and hard-wired to

MOONLink-compatible amplifiers.

This device must be configured for the Wi-Fi before enabling MOONLink with Wi- Fi. Once enabled, only connect devices with MOONLink functionality to the Ethernet ports on this device. A MOONLink Group should include no more than one preamplifier. Holding the Standby button on the front panel for two seconds automatically toggles Standby mode on all the devices in the MOONLink Group. Display Display On The display may be disabled so that only user interaction temporarily activates the display.
Brightness The display brightness is variable and may be customized.
· Brightness Level is a value from 0% to 100%. · Adaptive Brightness uses sensors to adjust automatically to ambient lighting in the environment. · MOONLink Brightness Sync duplicates the brightness adjustments of this device on other devices in the
MOONLink Group.
Background Image This device displays a pre-defined background image or none at all.
Screen Saver Two screen saver styles are available, which may also be disabled.
· Mode determines what triggers the screen saver. o One mode activates the screen saver after 20 minutes of silence. o One mode activates the screen saver after 20 minutes of inactivity.
· Style sets the automatic screen saver to display a blank screen or a floating MOON logo.
Volume Settings The highest volume setting of the preamp is 80.
· Startup Volume sets a default initial volume level. · Maximum Volume level sets an upper threshold to prevent accidents.
Standby Settings · Full Power keeps most of the electronics powered up while in Standby. · Low Power powers down most of the electronics while in Standby. · Auto-Standby engages Low Power Standby after 20 minutes of inactivity.
Firmware Certain hardware components in this device require firmware to function.
· Versions displays the various firmware versions currently installed. · Update begins the procedure of verifying and, if necessary, updating the firmware with on-screen guide prompts.
Information Device information, including its serial number, and certifications are displayed for referencing.
Reset The Reset procedure reverses all customizations (including input configurations) to factory default settings. It does not revert the firmware to an earlier version.
