Automix 4 User Manual Connections The inputs to the Automix 4 are balanced. This means that there are three wires for each connection, a positive, negative and shield. These should be connected to each pin accordingly. Also, each input has mic level connections AND line level connec- tions. However, only one set can be used at a time. Both connections feed the same gain stage. NOTE: On Channels 3 & 4, 48VDC phan- tom power is constantly supplied to the microphone inputs. Take care when con-

Connections The master output section features two independent sets of outputs, both from the final gain stage of the Automix 4. Normally, the main outputs that would be used to drive the primary power amplifier would come from the balanced output. The second- ary output, labeled LINE OUT is un-balanced. Both outputs can be used simultaneously. The MIC/LINE switch determines whether the balanced output is nominally at microphone level or line level. For driving power amplifiers, this switch

Automix 4 User Manual Each Channel of the Automix 4 has an insert connection that has several uses for connecting external components. The follow- ing examples and connection diagrams illustrate the most common method of using this powerful feature. For proper automat- ic mixing, the signal gain of the external component MUST be 0 db (unity). NOTE: These connections are unbalanced. Care should be taken when considering the distance, type of wire and type of external connection. This example s

Automix 4 User Manual Configuration Since the Automix 4 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 Automix 4 mixer. The Automix 4 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 in

Configuration The next step is to configure the Automix 4’s rear panel switches for your application. Although the unit is shipped from the factory with default switch values, you should make sure that these settings are correct for YOUR application. Let’s take a look at each one, and describe their functionality. First, there are the Channels 1-4 Insert Bypass/Enable switch- es. These switches determine the routing of the input Channel’s audio path. In the Bypass position, the signal is no

Automix 4 User Manual Restaurant The Automix 4 works very well in restaurant environments, since the gain management functionality provides an easy way to set up microphones, and not have to worry about levels or feedback. In this example, there are two paging microphones and a background music source. The areas where patrons are waiting for a table require voice paging. However, the paging is annoying to the main seating areas where people are eating. This configuration provides separate feed

Applications Airport Gate Area (Small airport facility) In an airport gate area, the sound system is often a stand-alone system that has feeds from the concourse system as well as the airport-wide system. In the gate area, several levels of priority exist. Mainly, emergency and critical announcements take priority, followed by local gate activity and concourse pages. This system is typically duplicated at each gate in the concourse. In this example, we show how this works easily with the Aut

Applications House of Worship Frequently, when designing systems for churches or other houses of worship, the sound system must accommodate multiple methods of operation. This example is typical when a large console is employed, yet the system still requires a simple operation method when a console operator is not available, or needed. When the facility is used for meetings, a small wedding or other application that requires only a few microphones, the Automix 4 can be easily implemented using
