MODULE & CARD DESCRIPTIONS

Full-featured Input modules are described throughout this manual. Limited-function versions (minus the Send or Utility bus controls), Net-only versions (no connectors) and Limited-function Net-only versions (no connectors nor Send and Utility bus controls) are also available.

Microphone Preamplifier Module

Five mic preamps, each with a trim pot under a security cover , come standard on the BMX 8 and -14. Ten preamps come standard on the other frame sizes. A second five or ten input Mic Preamp Module can be field installed.

Mic preamps take balanced input signals (from

-65 dBu to -30 dBu) and output balanced +4 dBu outputs for direct connection to a Universal Input module or to outboard processing equipment.

Universal Input

This module features two inputs (A and B), each can come from an analog or a digital source (source selection is set via a module DIP switch). DIP switches also set the analog input level or the digital attenuation. Each input has a fully independent parallel logic circuit for remote control of the module and/or module control of the source equipment. Each module has independent mic/

The Universal Input module has controls for the following functions: A/B input selection, input mode selection, channel on/off, fader level, solo, cue, pan/balance, two Send selectors and level controls, and ten output bus selectors (four program, four utility, and two off-line buses). A twoline display shows the A and B input source names .

Two 24-pin connectors connect logic wiring to/ from external peripherals or control panels for the A and B inputs. Two 14-pin connectors allow remote talkback (active when microphone logic is selected) for the A and B inputs. Four 8-position DIP switches set logic and module function options independently for the A and B inputs.

T elc o/C odec Input Module

An optional module that provides audio and logic connections for a telephone hybrid or a codec (satellite transceiver, ISDN interface, etc.). Up to six Telco modules can be installed in the frame.

Telco modules have digital and analog inputs (the active input is set via DIP switch) and the same controls as a Universal Input—minus the A/B input selector . Additional module controls include: telco monitor bus and telco record output assignment buttons, a Talk to Codec function, a Source Selector and a Take button (for source selection with a VistaMax, Ext. RLS or a router).

Each Telco module has an associated mixminus (Foldback) of an y combination of the program, utility or send buses and two off-line mix buses. An Auto-Foldback function can automate switching Foldback between an off-line mix and the assigned bus with module off and on.

Remote Line Selector Input Module

An optional module that offers source selection from a VistaMax system, an external remote line selector or a router . Each module has a digital and

an analog input (active input set by module DIP switch). Front panel controls are the same as the Universal Input, minus the A/B selection. Instead, there is a Source Selector and Take button.

Session

meter source selection, and event timer controls. There are eleven Aux Meter selector buttons (for viewing any External Input, Send, Utility bus, or T elco Record output) and two Main Meter selectors (PGM 1-4 and UTL 1-4) for viewing the Program or the Utility buses on the four Main Meters (on the BMX the buses to show one at a time on the Main meter).

Selector and two buttons: Take and Save. A twoline display shows the session currently being used and either the next session to be loaded, or when the Session Selector is being turned, the various sessions available in alphanumeric order.

Studio Module

This optional module has the monitoring and talkback controls for two separate studios or voice booths, plus talkback audio and control inputs for a producer/call screener position and for an external position.

The Producer and External audio inputs are line level. The Mic Preamp module may be used as needed for these inputs. A Producer Talkback / IFB Panel (PRE99-1188) is also av ailable. It provides a mic and preamp for the Producer along with T alk buttons for thirteen locations .

T he Studio module has two parallel logic connectors for the Studio 1 and 2 dim, mute, and Studio W arning Lamp interface controls .

The Studio module also has monitor and talkback selector controls, and monitor and talkback level controls. All of the controls operate independently for each studio.

Output Modules

There are three Output modules. The Output 1 module has the digital-to-analog converters and mix matrices for creating mix-minus foldbacks to support up to six Telco/Codec modules. It also contains individually mixed outputs for Telco monitoring and recording. Two monaural mix-minus outputs for each Telco/Codec module, one with talkback (IFB) and one with a clean feed, are on this module.

Digital and analog outputs are provided for the mix-minus and recorder feed outputs. For digital outputs, sample rates of 48 kHz and 44.1 kHz are supported. The mix-minus analog outputs are fixed at +4 dBu. This module features output sample rate selectors for digital outputs and gain trim controls for the analog Telco record mix output and IFB level.

The Output 2 and Output 3 modules contain the AES digital output drivers, digital-to-analog converters, and analog line amplifiers for the Pro-

Net Card

Specifications

The specifications for the BMX nificantly more complete, and the related test conditions are more defined, than those usually shown for consoles in this class. Be sure to follow the test conditions and measure in the units as stated.

The specifications are for a fully loaded BMX-

digital

38-input mainframe.

Test Conditions:

Specifications are for the basic signal paths, per channel, with >1 k ohm loads connected to the analog main outputs.

0 dBu corresponds to an amplitude of 0.775 volts RMS regardless of the circuit impedance. This is equivalent to 0 dBm measured into a 600 ohm circuit for convenient level measurement with meters calibrated for 600 ohm circuits. Noise specifications are based upon a 22 kHz measurement bandwidth. The use of a meter with 30 kHz bandwidth will result in a noise measurement increase of approximately 1.7 dB.

Total Harmonic Distortion (THD+N) is measured at a +18 dBu output level using a swept signal with a 22 kHz low pass filter.

POWER SUPPLY

The 99-1205 power supply requires 2 RU of rack space within the console cabinetry , below and to the left or right of the supporting countertop. The 48 Volt Power Supply must be installed so that the 30 foot power supply cable (90-1709) is not under any tension when routed through the cabinet and connected to the mainframe’s rear panel connectors.

Connecting the Power Supply

The power supply cable has two connectors:

• A 5-pin connector to supply 48 volt DC power to the console.

• A 4-pin connector to supply power status information (Imminent Power Loss) to the console.

Both connectors must be attached to the back

digital

of the BMX

and to the power supply.

GROUNDING AND SHIELDING

The broadcast facility’ s technical ground can be connected to the mainframe chassis using the threaded insert on the rear of the console (shown in the Power Connections drawing on this page). Use a 10-32 screw and crimp lug to terminate the facility’s technical ground wire.

Connect the cable shields at both the console and the peripheral end when all system components share a common ground potential and are using isolated ground A C outlets tied individually back to the main technical ground.

If isolated ground A C outlets are not available, connect the cable shields at the console end only. The shields should be floated (left unconnected) at the peripheral device end. Ensure the peripheral devices connect to a clean ground through their power cords, or through separate ground wires to the facility’s technical ground.

• Analog audio connections require twoconductor, stranded, insulated, foil-shield cable using a separate shield drain wire (equivalent to Belden 8451, 9451 or 8761).

• AES/EBU connections require 110 ohm two-conductor, stranded, insulated, foilshield cable containing a separate shield drain wire (equivalent to Belden 1800A).

• Logic control cables require stranded, 22 AWG, multiple-conductor, non-shielded, jacketed cable (equivalent to Belden 9423, 8457 or 9421). The number of conductors used is determined by the application. Typically cables with five and eight wires are most often used for constructing logic cables. Ev en though there are eighteen distinct signals on the Logic Interface connector, only a handful are typically used for any given application.

AMP MOD IV Receptacle Contacts

Follow these steps for audio wire preparation: 1 Strip the cable insulation jacket and foil shield

A ratcheting AMP crimp tool with contact holder is included. The tool crimps both the insulation and wire barrels on the AMP MOD IV receptacle contact in one crimp. To use the ratcheting crimp tool:

1 Insert the contact into the contact holder with

the barrel openings up. Typically the middle holder is used (for 20 - 24 AWG wire). Flip the holder up so it magnetically latches against the crimp tool. The end of the insulation barrel will be about 2 mm from the end of the die. Close the tool one click (only until the anvil holds the contact in place, as shown in the cutaway view, above.)

2 Insert the prepped wire into the contact until

the insulation hits the tool’s wire stop. Hold the wire in place while squeezing the tool

handles to crimp the contact onto the wire. The tool handles automatically release and spring open after the crimp cycle is complete.

AUDIO CONNECTIONS

Audio connections take advantage of the threepins per row design of the three- and six-pin AMP MOD IV housings. Three-pin housings are used for balanced digital connections while six-pin housings are used for balanced analog connections. One important exception is the Mic Preamp module, which uses three-pin connectors for balanced analog microphone inputs.

Pin Numbers for Analog &

Digital Audio Connectors,

3 2 1

3-pin

connector

Pin numbering shown from the wire insertion end,

oriented from the board operator’s perspective.

All audio wiring, when plugged into a module connector, has this orientation:

• The audio shields are on pins 1 and 4 (the pins closest to the board operator).

• The audio low wires (typically the black wires) are on pins 2 and 5 (the middle pins).

• The audio high wires (typically the red wires) are on pins 3 and 6 (the back pins).

For stereo applications, the left channel wires plug into the left column of pins and the right channel wires plug into the right column of pins (from the board operator’s perspective).

When a six-pin input comes from a mono source (such as an external microphone preamp output), the left and right inputs should be paralleled together (pins 1 and 4 tied together, pins 2 and 5 tied together and pins 3 and 6 tied together). If this is not done, then the module’s mode buttons will have to be set for mono operation (see page 35 for L/R Mode information on the Universal Input Module).

Analog Connections

There are no analog interstage patch points

input or output modules. To use the console with a patch bay, connect the line level outputs from the peripheral devices directly to the patch bay. Normal these signals to the appropriate analog input modules.

digital

Likewise, the BMX

’s analog outputs may be routed through a patch bay normalled to standard peripherals such as analog on-air processing gear , recorders, telephone hybrids, etc.

The Mic Preamp module’ s line-level outputs (+4 dBu, nominal, balanced, mono outputs) can also be routed through a patch bay normalled to an input module, or to external mic processing .

When a mic processor with only a microphone level input is used, the microphone is connected directly to the mic processor , with the processor ’s line-level output either directly connected to an input module (using the mono wiring pinout shown below) or through a patch bay normalled to an input module.

UNBALANCED CONNECTIONS

Although all analog inputs and outputs are active and balanced, unbalanced consumer or “semipro” equipment can be connected to the console. For best results, connect an unbalanced device through an IHF-PRO match box and keep the unbalanced cable lengths as short as possible.

DIGITAL CLOCK REFERENCE

The BMX rate timing, with sample rate converters on each input to synchronize/convert external digital signals to the console’s internal 48 kHz sample rate.

The console can synchronize to an external AES3 digital reference signal (of 48 kHz, ±100 ppm only) when using the optional Ext. Input DSP card (99-1356-1). A 3-pin connector on the card has a green LED next to it to indicate whether the internal or external reference is active. When a valid external reference signal is present, the LED is off. If the LED is still lit with an external signal connected, it indicates the reference signal is not present or is out of range.

modules have built-in logic I/O interfaces that can control, or be controlled by, peripheral devices connected to the console. For example, a CD player connected to a module can be automatically started when the module is turned on. Then, at the end of the cut, the CD Player logic can turn the module audio off and control the off button illumination to indicate that the cut has been played.

When a mic remote control panel is connected, its On, Off, Cough and Talkback buttons control the module while tally outputs from the module control the button tallies on the mic panel.

BMX connectors:

• Universal Input modules have two MAIN connectors for the devices connected to the A and the B inputs and two T/B OPTION connectors for separate talkback control for the A and B mic inputs.

• Telco/Codec and RLS modules have a single LOGIC I/O connector for the device connected to the module.

• The Session module has three EXT TIMER connectors for resetting studio or producer timers, a D AT A (RJ-45) connector for connecting the console to a local LAN and the connectors for the factory-installed wiring that ties the mainframe to the meter panel.

• The Control Room module has a LOGIC connector for the warning light, mute, dim, and talkback. A CUE CNTL connector allows external cue input control.

• The optional Studio module has two LOGIC connectors for dim, mute, and warning indications and two talkback connectors (PRODUCER and EXTERNAL).

• The Output 1 module has a PRODUCER IFB LOGIC connector.

Note: F or complete isolation of the console and a peripheral device, use only the opto-isolated control connections. Both logic ground and +5 VDC are referenced to the console’s power supply and ground and should only be connected to isolated devices like mic control panels or other Harris Accessory Panels. Connecting logic ground to a nonisolated device may result in a ground loop between the console and the peripheral device.

UNIVERSAL LOGIC INTERFACE

A block diagram of the Universal Input module logic interface is shown on page 2-13. Logic outputs (shown on the right side of the illustration) are isolated from the peripheral device by six solidstate “relays. ” T he “relay contacts” can switch logic voltages of up to 60 volts at 350 mA.

Pressing the On button generates a 220 ms contact closure from pin 5 (Start Command Pulse). A sustained contact closure while On is available on pin 23 (Start Command Sustained). It stays closed as long as the module is On. Pressing the Off button generates a 220 ms closure from pin 4 (Stop Command Pulse). These three command outputs are tied together at pin 13 (Command Common).

Module DIP switches DS2-2 (for the A input) and DS4-2 (for the B input) , set whether a single pulse is output when the module status changes (Off to On, or On to Off), or if each additional press of the On or Off buttons produces another contact closure. The default setting (switch 2 set to OFF) is a single contact closure. When DS2-2 or DS4-2 is set to ON, then each additional press of the On or Off button produces another 220 ms contact closure.

T he remaining outputs; Logic Active/Cue Tally [pin 15], On Tally [pin 17], and Off Tally [pin 16], are tied together at Tallies Common [pin 14]. T hey present sustained logic outputs for each function.

There are six logic inputs on the left side of the illustration: Reset, Ready, On, Off, Cough and Talk to Control Room/Ext. Cue. These inputs are optoisolated and current limited so any logic voltage from +5 to +40 VDC can be used. Reset and Read y have both high (+) and low (-) input pins so that either polarity logic can be used. The other inputs use active low logic (pull to ground) that typically come from a mic control panel (although On and Off could be triggered by a peripheral device). To use these inputs, pin 18 (Activate Logic Inputs) must be jumpered to the + logic voltage. Typically

this is pin 6 (Logic Supply +5 VDC), but it can also be supplied by the peripheral device.

The Audio Reset and Ready inputs can use either active low logic (pull to ground) or active high logic (pull to +VDC) from peripheral devices. With active high logic, Ready (-) and Audio Reset (-) are tied to logic ground on the peripheral device. Ready (+) and Audio Reset (+) then connect to the appropriate logic outputs on the peripheral device.

When active low logic is used by the peripheral device, Read y (+) and A udio Reset (+) connect to the logic supply voltage on the peripheral device, and Ready (-) and Audio Reset (-) connect to the appropriate logic outputs.

Pin 15’s signal (Logic Active Tally / CueTally) changes depending upon whether the channel logic switches (DS1/DS3) are set to mute any location. When any mute is set (DS1/DS3, switches 2 - 5

are set to On), the module is set as a microphone and the Logic Active Tally output (pin 15) is closed when that input (input A for DS1 or input B for DS3) is active. When no mute is set, the module is set for line logic and pin 15 becomes a Cue Tally.

Setting DIP Switches

When referring to a module’s DIP switch setting, a switch is Set to Off when it is to the right and it is Set to On when it is to the left (orientation is from the board operator’s perspective). In

the illustration, all odd numbered switches are shown set to On and all even numbered switches are shown set to Off.

On = set Left

Universal Input Module Logic and Mics

Microphone logic has three main functions: to mute the monitor speakers in the room with a “hot” mic; to command a hot mic warning light; and to activate logic functions like talkback and cough.

The warning commands come from the Control Room or Studio modules, but it is the Universal Input modules that tell the monitor modules that the input is a mic and where that mic is located (control room, a studio, or an external site).

Setting a Universal input module as a mic input is done by either setting DIP switch 2, 3, 4 or 5 to On on DS1 (A input) or DS3 (B input) or, when a console is tied into a VistaMax system, b y assigning the input using its Room Code. The Room Code is a VistaMax system function that sets the room using a Session file setting that is typically used when the mic is routed through the VistaMax system.

Direct Mic Connections

Pages 2-58 and 2-59 summarize setting up a Universal Input module as a direct microphone input, utilizing a PRE99-1198 Mic P anel (simplified schematic shown below). This is typically how mics in the control room or in a dedicated studio are connected. Both the mic audio and the mic

logic are wired directly to an input module’s connectors. This is typically how mics are wired even when the console is connected to a VistaMax system since the active input mic audio can be made available as a VistaMax source—allowing the mic audio to be routed to another console or other destination in the VistaMax system.

VistaMax Mic Connections

When a studio, voice-over booth, or other external location will be shared by multiple control rooms, then the shared mics should be routed through the VistaMax system. This then allows

digital

each BMX

console to independently control the mics (just as if they were directly connected to the console) via the VistaMax system.

The shared mics and their mic panels are wired directly to an Analog I/O and a Logic I/O card in a VistaMax frame. The logic signals for the mic panel are “bound” to the mic audio during setup. Thus, selecting a mic as a source by any console automatically routes both the audio and logic to that console through its Net Card. Tally commands from the console to the mic panel are routed through the Net Card and the Logic I/O Card.

For additional networked audio information refer to the VistaMax manual (Harris # 75-52).

pole, single throw) momentary contact switches with LED or lamp indicators. Lamps must be 6.3 volt type with a current draw of under 50 mA.

Tie one side of each switch and lamp to Logic Common (pin 1, 2 or 3 on the MAIN connector). The other side of the Cough and Talkback lamps are tied together to Logic Active Tally (pin 15).

Each switch is tied to its logic counterpart (the On switch goes to the On (-) input, pin 7, the Off switch goes to Off (-) input, pin 8, etc.). The on/off lamps are tied to their Tally outputs (On lamp to On Tally, pin 17; Off lamp to Off Tally, pin 16).

T allies Common (pin 16) is jumpered to +5 VDC (pin 6, 10, 11 or 12). Pin 18, Activate Logic Inputs (+), is also jumpered to +5 VDC (typically pin 6 is used).

Input Module Logic (Universal Input, T elc o/C odec , RLS) and Peripheral Devices

Peripheral devices are controlled through the Start and Stop Command Pulses, or through the Start Command Sustained logic, and the Commands Common connections.

In the basic logic connection example on pages 2-60 and 2-61, activ e low logic is used, thus Commands Common is connected to the logic ground on the peripheral device (labeled Command Common on the Denon CD player in the example).

In the complex logic example shown on pages 2-62 and 2-63, active high logic is used, thus Commands Common connects to +5 VDC.

Note: This voltage is more typically supplied directly by the peripheral device in order to prevent ground loops.

Peripheral devices control the module through the Reset and Ready logic inputs. In the example on pages 2-60 and 2-61, only the Read y function is used. The Ready function performs an audio Reset, which turns off the module without generating a Stop Command Pulse. In addition, it also controls the Off lamp illumination.

Pages 2-62 and 2-63 show an example where Reset (+) and Ready (+) connect to +5 VDC on the module. The Ready (-) command and the Reset (-) command are pulled low by the active low logic relay outputs on the peripheral device, which all tie to the module’s Logic Ground (pin 1).

For devices requiring a steady On signal, the Start Command Sustained output can be used.

Additional Logic Connections

There are additional logic connections on the Session module, Control Room module, optional Studio module, and Output 1 module.

Three 3-pin connectors on the Session module interface remote timers so they can be reset by the console timer reset logic. The Session module also has factory-installed cabling for the clock and timer , the talkback mic, the digital meters and the meter legend display data. For more information on the Session module’s logic connections and settings, see pages 2-32 and 2-33.

A 14-pin connector on the Control Room module carries the logic interface for the Control Room warning light, mute, dim and talkback. An 8-pin connector on the Control Room module controls the External Cue input. For more information on the Control Room module’s logic connections and settings, see pages 2-34 to 2-38.

The optional Studio module has two 14-pin connectors to control the two studios’ logic (warning lights, mutes, dims). The Studio module also has two 16-pin connectors: one for the talkback audio and logic for a producer , the other for talkback audio and logic from an external site. For more information on the Studio module’s logic connections and settings, see pages 2-40 to 2-49.

The Output 1 module includes an 8-pin connector to control the producer’s talkback to each mix-minus output. For more information on the Output 1 module’s logic connections and settings, see pages 2-50 to 2-53.
