INSPECTION 1. Unpack and Inspect the MX54s package Your MX54s was carefully packed at the factory in a protective carton. Nonetheless, be sure to examine the unit and the carton for any signs of damage that may have occurred during shipping. If obvious physical damage is noticed, contact the carrier immediately to make a damage claim.

DESCRIPTION REAR PANEL Mic Input: 1 - 3: XLR balanced inputs for connection to any standard dynamic or condenser microphone. Right and Left Outputs: Transformer balanced XLR output jacks for connection to the next device in the signal chain such as a signal proces- sor or amplifier. Right and Left Trim controls: Screwdriver adjustable controls to vary the level of each output. NOTE: These controls are set at mic level from the factory. Turning them counter-clockwise increases the output level. These controls do not effect the Aux/Headphone Output. FRONT PANEL Mic Level 1 - 3: These controls adjust the level of the corresponding Mic channel. The level varies from -infinity (off) to +60 dB of gain (typical). PAN 1 - 3: Adjusts the relative right/left level of each channel. Phone/Aux: 1/4 TRS jack which may be connected to a pair of head- phones for personal monitoring, or to an unbalanced input of a signal processor or amplifier. Power LED: Indicates the MX54s is on. Clip LED: Indicates that clipping is about to occur or occurring in the MX54s circuitry. This LED begins to light 3dB below actual circuit clipping. Power Switch: Applies power to the MX54s. Located on the right side of the unit is the +12 VDC power jack for connec- tion to an optional +12 VDC (outside of the ring is positive) external power supply. We recommend the Rolls PS27. Locatd on the left side of the unit is the battery compartment which houses two 9-Volt (alkaline preferred) batteries. Also on the left side are the Phantom Power and Low-Cut switches. As shown here, under each number is a P indicating Phantom Power, and an L which indicates Low-Cut. When the P switch is DOWN, the phantom power is ON, when it is UP, the phantom power is OFF.When the L switch is UP, the low-cut is ON, when it is DOWN, the low-cut is OFF.
