Please read this Owner's Manual carefully and understand how to operate the device correctly before use. We hope that you will fully use the features of this unit for many years to come. After reading this manual, please keep it in a convenient place for future reference. Overview The LA-40MKIII has 4 internal circuits to convert unbalanced inputs to balanced outputs and 4 internal circuits to convert balanced inputs to unbalanced outputs. In addition, the Audio Distributed Amplifier (ADA) function allows single inputs to be assigned to multiple outputs using the INPUT LINK switches between each channel. for the entire unit · Each channel has an INPUT/OUTPUT LEVEL switch that allows input and output levels to be switched between -20 dBu and +4 dBu · Level indicator LEDs that show signal presence · Semi-fixed TRIM controls for fine level adjustment of ±12 dB · Rack mount brackets · Three-prong AC power outlet (Not on EUR model) · GND LIFT switches to turn the ground ON and OFF for each balanced connector · ALL LIFT switch that turns the ground ON and OFF Supplied accessories The following items are included with this product. · Main unit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 · Power cord set. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 · Rack mount screw set . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 · Owner's Manual (this document) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 · Warranty card . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Contact your TASCAM supplier if any of these items are missing.

[. . . ] w Level indicator LED switch If this switch is ON, LEDs light when input signals are present. If this switch is OFF, the LEDs do not light regardless of the presence of input signals. e GND connector When multiple pieces of equipment are connected, use this to make the chassis of each piece of equipment have the same electrical potential. The GND LIFT switches do not cut the ground for the INPUTS 6. 6 TASCAM LA-40MKIII E_LA-40mkIII-OM_RevC. indd 6 08. 12. 19 1:03:23 PM 2­Names and Functions of Parts r Power outlet (see NOTE below) Use this three-prong outlet, which is not affected by the power switch, to connect AC equipment with a maximum power consumption of 400 W (or 3A). The specifications are displayed on the top of the unit. NOTE The EUR model does not have this power outlet, so the panel here is blank. t AC IN connector Connect the included power cord.
