The AMB-5 is a single rack space five by one automatic mixer designed to be configured with a computer and appro- priate software. Once initially setup the computer becomes optional. The key to the ability of the AMB-5 operating as a stand alone automatic mixer is distrib- uted intelligence™. In an IQ System the brains of the system live out in the sys- tem. This means the audio system is not going to be lost even if the computer or communication cables fail. The AMB-5 is a unique mixer because it is capable of sensing ambient crowd or machine noise. It uses this as a reference to ad- just the gain of the five main audio in- puts. The AMB-5 also has a non-auto- mated output which may be used for monitoring or other purposes. HARDWARE BLOCK DIAGRAM Refer to the pictures of the front and rear panels shown above and the block dia- gram of the AMB-5 mixer on Page 2. Audio Main Inputs: Six balanced inputs with removable 3 pin barrier block. The preamp stage in- cludes: • M/L/P switches set each input to line level (L) with 0 dB gain, mic level (M) with 25 dB additional gain, or phantom (P) which is 25 dB additional gain and +44 VDC phantom power. • A trim pot at each input allows for prefade gain adjustment of –12 dB to +21 dB gain after the M/L/P switch. • Main input 6 is the noise sensing input. Although it is used differently than the other main inputs, it has the same basic features as main inputs. Prefade sensors at the output of each preamp stage sense input audio level just before the input signal is delivered to the processor controlled VCAs. There are two VCAs under processor control at the output of each sensor. One VCA controls the gain from input to output mix 1 and the other VCA controls gain from the input to output mix 2. The net result is 11 VCAs total, five per output mix with one VCA to route ambient noise (input 6) to output 2. Note that in the AMB-5 there is no VCA control for input 6 to output 1. Audio Stack Inputs: Two inputs, one per output mix. Connec- tions are via unbalanced RCA phono jacks. These inputs are op-amp isolated. There is no processor control of audio coming into these inputs. The purpose of the stack inputs is to allow construc- tion of a wide mixer with more than six inputs by taking the outputs of one mixer and going into the stack inputs of a sec- ond mixer. This means that main inputs do not have to be used to expand the effective size of the overall mixer. Audio Main Outputs: There are two summing buses. Each summing bus provides the out- put mix for the corre- sponding output chan- nel. Op-amps buffer the summing bus to the output connec- tion and balance the audio output. The outputs are via 3 pin removable barrier blocks. Audio Bus Outputs: In addition to the two main outputs, there are also two bus outputs. Bus outputs 1 and 2 provide the same audio output as main outputs 1 and 2. Op-amps buffer the summing bus to the output connection and balance the audio out- put. What makes the Bus Outputs dif- ferent are relays under processor con- trol which may be used to turn on or off the Bus Output drive. 3 Pin removable barrier blocks are used. Aux Port: The unit is equipped with a TB-3M type mini-XLR port. This port may be used to provide a control signal or sense a con- trol signal. Pin 1 is ground reference. Pin 2 is output under processor control. When on it provides 10 VDC at 16 ma. When off it is open collector (high im- pedance). Pin 3 is sensing input. +5 to +30 VDC is sensed as a logic high. The circuit floats, therefor tie to ground or TTL source for definite high or low. Indicators: A Power light on the front panel indicates the unit is powered. A DSPI data signal presence indicator indicates communi- cation. Crown Bus Port: The Crown Bus is a serial data loop where components are connected into the loop and one component serves as system interface for all. This unit may serve as a system interface or may sim- ply operate as a component on a Crown Bus data loop. Although the Crown Bus may function on a variety of media, Crown uses a two-wire 20 ma current loop for input and output Crown Bus connections. On this unit connections are made via 4 pin removable barrier block. Even if the unit is communicating directly with a PC via its serial port, it always functions in software as an ad- + – AUDIO IN 1 L M P 0 -5 -10 -12 5 10 15 21 ADD 25 FOR MIC + – + – AUDIO OUT 1 MAIN BUS STACK IN AMB-5 Automatic Mixer (Page 1 of 5)
