Powering DownYou can turn the preamp off (place in standby mode) by holding any of the 6 buttons until the device powers down (about 1 second).Premium IR Remote Control OperationThe group of six buttons on the remote control mirrors the front panel buttons. Pushing any of them will power the device on and/or engage the associated preset and/or mute the unit. The top button acts as mute/standby button and does the exact same as the preset buttons except it does not switch presets. This is mainly useful because the remote control unit obviously does not have LEDs to indicate which preset is engaged and sometimes you just want to mute the device regardless of what was playing.The volume up/down buttons operate as they do anywhere else. The LED on the volume knob will come on to provide easy visual feedback of the volume setting.Standard IR Remote Control OperationThe standard-issue RC unit works slightly differently. The button in the middle of the quadrants turns the preamp on or off (hold 1 second for off). Press this button once for mute or unmute. Pushing on the left and right quadrants of the ring cycles through the 6 presets. The top and bottom quadrants control the volume. The two lower buttons are not used.Android® and iOS®Your preamplifier is fitted with a Bluetooth® module to allow access with a mobile device.
