Dear Customer! Thank you for choosing our product. LINE MIDI SWITCHER (LMS-1) is a bidirectional, passive switcher of the audio signal with galvanic separation between A, B, C, D outputs/inputs. The LMS-1 can be used as amps switcher in “one of four” mode (guitar connected to an input of selected amp) without occurring of the ground loops.
Power supply LMS-1 should be supplied from 9V (DC) regulated source with capacity 100 mA or more. Before plugging the power supply please check the pin polarization. The device is protected against opposite polarity. If this protection switches on it is needed to disconnect the power supply and wait few minutes before reactivation of the device.
Working mode switches The LMS-1 posses two working modes set by DS1 switch - DS1=OFF, one input/four outputs, Y IN/ABCD OUT, this working mode enables for example to choose the amp to which the guitar will be plugged in - DS1=ON, four inputs/one output, ABCD IN/Y OUT, this working mode enables to choose signal source (e.g.
Way of connecting Scheme No. 1 (on the inside front cover of the manual) shows the way of connecting in mode one input – four outputs (Y IN/ABCD OUT). Scheme No. 2 (on the inside back cover of the manual) shows the way of connecting in mode four inputs –...
AB GND and ACD GND ground switches In the mode one input/four outputs (Y IN/ABCD OUT). The AB GND and ACD GND grounds switches enable to set the grounds connections in the way that eliminates ground loops occurring or to connect the grounds in order to eliminate hums and switching noises.
In the mode four inputs/one output (ABCD IN/Y OUT). When the guitars (or other signal sources not connected to the grounding) are connected to the ABCD inputs the AB GND and ACD GND switches should be set to ON position. MIDI functions To set the MIDI channel on which the LMS-1 receives the commands serves the MIDI CHANNEL rotatable knob.
