The mic input channels have a 2 band EQ. There is an echo reverb effect on the mixer, which can be applied to the two mic channels. The control of the effects include repeat, interval and level. Pan control and peak LEDs are available on all channels. Volume controls are available for the USB player, each input channel, headphone and main outputs.
USB Recorder and Player
After inserting a USB stick, the transport buttons are utilised for the recorder/player, along with an LCD screen. The buttons allow for moving through the USB directory easily, and to select the files for playback. Long presses on the forward and backwards transport keys will increase and decrease the volume. Once a USB stick is inserted, any files on board will start playback automatically. A short press of the menu button provides the ability to select playback modes, such as random or repeat, EQ application, directory selection or deletion of files. A long press of the menu button enters the recording mode. File formats can be selected here as well, including lossless APE and FLAC.
When no USB stick is inserted, pressing the press any key quickly, and select BT mode. The bluetooth name of this module is BT-SPEAKER. Once paired with your device, streaming is automatic.
