[. . . ] WARNING: When using electrical products, basic cautions should always be followed, including the following: Do not use this apparatus near water. Do not block any of the ventilation openings. install in accordance with manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. [. . . ] These should be connected to each pin accordingly. Stereo Inputs Channels 7 and 8 provide two inputs for each channel. These are intended for stereo use, as each input (Left, Right) has a fixed assignment to the Left and Right output buses. additionally , a sum of both inputs is fed simultaneously to the Aux output bus. Although you cannot change the distribution of these inputs, you can determine if they are stereo or mono. The Mode switch, when enabled, will sum both connectors, feeding both to the Left and Right outputs simultaneously. These connectors accept nominal levels of -10 dBV. This allows for only one input to be used to feed stereo mix buses. The cabling for these connectors should be of the standard, consumer unbalanced shielded type. If you are using a 2conductor shielded cable, make sure to connect the negative side of the signal to the shield. Note: Unbalanced signal sources should be located within approximately 6' of the SMRTM821a. Configuration Since the SMRTM821a is an analog product, there is not a lot of configuration to worry about. no software , no data cables , no networks and no headaches. However, there are a few things to remember while you begin to use your new SMRTM821a mixer. The SMRTM821a is shipped from the factory ready to go. You should be able to follow the steps below and get audio through the unit. The first step is to calibrate your gain settings for the inputs. each microphone input has a Gain Control and a Level Control. These controls work together while the Status LED and the master Level Meters provide a visual indication of the control's behavior. To properly adjust the SMRTM821a for optimal performance, follow these simple steps for each input channel: 1. adjust the Channel , Left , Right and Aux Level Controls so they are at the midpoint. There is a center detent on the control which indicates this position. [. . . ] The transformers can only be inserted into the board one way. Place a transformer into the circuit board and solder in place. Repeat process for each transformer being installed. re-installing the Circuit Board and Re-assembling the Unit 1. [. . . ]
