Page 8: The Am-16/B Master Crosspoint Switcher
Expander Modules connect to the master unit by a single flat cable and are self-powered. They require no controls, and are designed for use only with the AM-16/B master. A maximum of three expanders may be connected to a single master. -
Page 9: Remote Control Capabilities
Section 2.41 describes selection of MIDI or EIA-485 communication modes from the front panel. EIA-422 is a receive-only port on the AM-16/B. It is possible to connect a number of switchers to a single 422 cable in a multi-drop configuration, with each listening on its own channel. -
Page 10: Using Midi & Eia-485/422 At The Same Time
Appendix E. 0.33 USING MIDI AND EIA-422/485 AT THE SAME TIME When the 422/485 port is used, the AM-16/B is not listening on the MIDI input port. However, MIDI program maps (see section 2.30) and bulk data transfers may still be transmitted through the MIDI output port. -
Page 11: Ac Power
1.12 FUSE The A.C. fuse is located on the rear panel of the AM-16/B. Replace it only with the same type and rating. For 120 volts, use a 1-amp, 3AG slow-blow. For 230 volts, use 1/2-amp, 3 AG slow-blow. -
Page 12: Audio Input Connections
1.23 BALANCED VS SINGLE-ENDED GAIN STRUCTURE The gain of the AM-16/B depends on the type of connection made to it. A gain of unity might be obtained with a balanced input connected to the + and - input terminals, and a balanced output measured between the + and - output terminals. -
Page 13: Front Panel Audio Jacks
Pin 9 1.31 MIDI INPUT PORT Use a standard 5-pin MIDI cable to connect the MIDI IN of the AM-16/B to the MIDI OUTPUT of a MIDI equipped computer or MIDI program number transmitter. Any device capable of sending program numbers via MIDI may be used to control the AM-16/B, i.e. -
Page 14: Interface Port To Am-16/E Expander Modules
Jumper JP1 (located on the front panel printed circuit card) selects whether the AM-16/B operates as a 16 x 16 monaural switcher, or whether programs are paired together for stereo, as an 8 x 8 unit. Place the jumper between the center pin and the appropriate outer pin. -
Page 15: Eia-422/485 Termination Jumper
AM/16-B Audio Switcher Place the jumper between the center pin and the appropriate outer pin. One is marked "MIDI", and the other is marked "485". Be certain to select the "normal" (MIDI) or "485" communications mode as described in section 2.41. 1.43 EIA-422/485 TERMINATION JUMPER When using long lines to send data via EIA-485 to the switcher, improved wave shape can be achieved by resistively terminating the line. -
Page 16: Using The Am-16/B Audio Switcher
2.01 THE EDIT BUFFER As a convenience to the user, the AM-16/B allows all editing to be done in a temporary memory space called the Edit Buffer. Information placed in the Edit Buffer can be altered, deleted and reviewed without fear of damaging "real information"... -
Page 17: Remote Program Selection
2.12 REMOTE PROGRAM SELECTION Programs can also be recalled through remote program change commands without touching the front panel buttons. To receive them, set the AM-16/B to the channel number on which the programs are to be transmitted. (See section 2.60) When a program number is received, the switcher retrieves the program from memory and configures itself accordingly. -
Page 18: Multiple Input Assignments
AM/16-B Audio Switcher The right display indicates the DESTINATION to which an input will be assigned. Select a destination first, using the arrow buttons under that display. The center display indicates the SOURCE to be assigned to that destination. Use the arrow buttons under the center display to select the source. Selection of a source must be done after the destination has been selected. -
Page 19: Storing Edited Paths As A Program Number
2.24 THE STORE-PENDING TIMER In the "Store Pending" mode, the AM-16/B's computer is waiting to see if a program number is selected and finally stored. Four seconds are allowed to complete the operation. If at the end of that interval the STORE button has not been pressed a second time, the store-pending mode will be exited. -
Page 20: Copying Programs
AM/16-B Audio Switcher memory protect off, and resume the store operation. Memory protect also affects remote control STORE commands. Note that Memory Protect must be Off in order to use the unit with an AM-16R Remote Control. It is a good idea to use the "System Exclusive" data transfer capability to create external backup copies of memory. -
Page 21: Program Send Mode
AM/16-B Audio Switcher 2.30 PROGRAM SEND MODE Each of the 100 stored programs carries with it a set of eight program change commands, which are transmitted from the MIDI output port each time a new master program number is selected. Each program change command within the set of eight consists of a channel number and a program number;... -
Page 22: Storing Midi Program Maps
AM/16-B Audio Switcher particular PROGRAM SELECT number within the switcher. If this number was selected earlier, it may now be stored as described in the following Section 2.32. 2.32 STORING MIDI PROGRAM MAPS Press STORE once. The PROGRAM SELECT mode will be entered, and the STORE PENDING LED will light. -
Page 23: Program Send Enable Mode
At times the MIDI program send information may not be wanted at the equipment it was intended for. For example, a digital reverb under MIDI control will always select the program commanded by the AM-16/B, while you may have need for something different. -
Page 24: Selecting A Stored Chain
AM/16-B Audio Switcher Once a chain has been recalled, it may be incremented using either the front panel controls, remote control commands or a momentary footswitch. 2.51 SELECTING A STORED CHAIN Chains are selected from the front panel by entering the PROGRAM CHAIN mode, selecting a chain number from 1 to 27 with the left arrow buttons, and pressing ENTER to initiate step one. -
Page 25: Storing A Chain
AM/16-B Audio Switcher 2.53 STORING A CHAIN Press STORE once to enter the store-pending mode; if the chain number appearing in the left display is suitable, press STORE again to write the chain to memory. If not suitable, use the arrow buttons under the left display to select another number between 1 and 27. -
Page 26: Selecting Chain Steps Through Midi
MIDI controller #97 decrements the chain step number. 2.60 RECEIVE CHANNEL MODE The AM-16/B receives remote control data on MIDI channels 1-16, and in Omni mode, which is all channels simultaneously. It can also be turned off and ignore all incoming channel data. When a new channel number is selected, it will be stored in non-volatile memory. -
Page 27: Mono/Stereo Modes
AM/16-B Audio Switcher 2.70 THE MONAURAL MODE The AM-16/B is shipped from the factory set for 16 x 16 monaural operation. The MONAURAL LED on the display indicates this mode. Note that when operated in the monaural mode, the stereo mode switch described below is not active. -
Page 28: Programming Bypass
Connect a MIDI cable between the MIDI OUTPUT of the computer and the MIDI IN of the AM-16/B. The switcher will recognize system exclusive data as soon as it appears, and load it into the RAM. -

Page 46: Appendix Hoperation At 38.4K Baud
APPENDIX H OPERATION AT 38.4k BAUD The AM-16/B operates at 31.25k baud because that rate is used by all MIDI equipment. MIDI interfaces are available on a number of computers, including the ATARI 1000. MIDI ports may be added to IBM-compatible computers with the ROLAND MPU-1PC or MPU-401 MIDI adapters.
