DESCRIPTION

The Model SPK300L, a Portable Speaker User Station, is a component used in the TW INTERCOM SYSTEM. Each User Station is a communications unit along a multi-unit conference bus.

Figure 1, “TW System Concept Block Diagram,” on page ii, shows User Station interconnection, and User Station connection to the system power supply.

User Station interconnection can be: 1) centrally wired, with each cable coming from a central point, or 2) distributed, where all the user stations are looped together from one to another, or 3) a combination of both. The centrally wired interconnection not only reduces interchannel crosstalk, but also allows for easier expansion into an assignable channel, multi-channel system.

Figure 1, "SPK300L Block Diagram," on page 3, shows user station functional components, input/output connections, and controls.

The SPK300L User Station has the following

functional components:

• a microphone preamplifier with limiter
• an electronic microphone switch
• a "bilateral current source" line driver
• a listen volume control
• a headphone amplifier
• a speaker amplifier
• a speaker switch
• a channel selector switch

The Microphone Preamplifier/limiter converts the small microphone signal to a strong line level signal conditions the signal strength from loud and soft talkers to be almost the same sends the signal to the line via the microphone switch and a "bilateral current source".

The Bilateral Current Source adds signal, via the channel select switch, to the line without affecting any signals already on the line. The bilateral current source also extracts the listen signal from the line and sends it to the headphone amplifier via the volume control. Some of the user's own voice signal ("sidetone") is also fed to the headphone amplifier.

The Channel Selector Switch selects the channel on which the user will talk and listen. The headphone amplifier output drives the user's headphones.

The Volume Control also feeds the speaker amplifier via the speaker switch and the speaker dim network.

The User Station Voltage Regulator takes power from channel 1, regardless of the channel selector switch setting (exception: local power option units). The regulator not only supplies regulated power to the user station, but also prevents unwanted interaction between the user station and the intercom line which is supplying the power. Because the regulator takes power from channel 1, channel 2 can be expanded into many channels by using a switch and, for each channel, a separate wire and a termination network consisting of a 200 ohm resistor and a 10 microfarad capacitor in series. (See the Application Diagrams in the TW Intercom Systems Technical Manual).

A TW System Power Supply terminates a line with 200 ohms.

Operational Controls

The SPK300L User Station has the following controls, described and shown in Section 3:

• Channel Select Switch
• Latching-action Microphone ON-OFF toggle switch.
• Momentary-action Microphone ON-OFF pushbutton switch.
• Speaker/Headphone Volume Control
• Call Switch /indicator
• Speaker ON/OFF switch
• Sidetone Adjustment

Connection, Inputs and Outputs

The SPK300L User Station has four input/output connectors:

• Dynamic Microphone type headset or handset
• Carbon Microphone type headset or handset
• Line Input (ties the station to the intercom line
- Loop/extension (allows another station to access the line through the first station. Also called loop-through.

DIMENSION

MECHANICAL INSTALLATION

The Model SPK300L Portable Speaker User Station is 4.0 inches (101.6 mm) high X 8.0 inches (203.2 mm) wide X 8.0 inches (203.2 mm) deep. Additional depth should be allowed for the rear panel XLR-type line connectors. When installing this unit, allow space for control access, cabling and servicing. Provide space for: cabling service loops, reaching XLR-type connector lock releases, and headset connector/cables. If the headset connector is remotely located, allow space between this cable and interference sources such as video/TV monitors, power supplies and equipment with internal power supplies. There are no ventilation requirements.

Headset Requirements

Dynamic microphone headset type:

• 50 to 1000 ohm microphone
  • 25 to 1000 ohm headphone(s)

High efficiency headphones are recommended because less line current is required from the power supply. Use headphones with an impedance of 25 ohms or greater. Low impedance 8 ohm headphones are not recommended. Headphones with good acoustic isolation (20 to 40dB) improve communication in high ambient noise environments, and allow the user to use the headphones at a less tiring, lower volume.

In the headset connecting cable, prevent coupling between the microphone and headphone leads by using a shielded, twisted pair for the microphone, and a separate, twisted pair for the headphones. Do not allow headphone ground to contact microphone ground or shield. Tie the shield to microphone ground or "mic low". The headset cable can be made longer when the microphone and headphone pairs are physically separated. The wider the separation, the longer the cable length which may be used. Estimated maximum usable headphone cable lengths are as follows:

Single cable,

Two shielded twisted pair 10 ft. (3 m).

Dual ribbed cable,

Two shielded twisted pair: 30 ft. (9 m).

ELECTRICAL

Power

The SPK300L receives electrical power from either:

(1) a system power supply (26 to 32 volts DC on line connector pins 2 (+) and 1 (com) (1 or two channel operation); or
(2) a local power supply option (14 to 26 volts DC). A user station requires 18 to 33 volts to be a 10,000 ohm bridging impedance across the powering line, but the station can otherwise operate (as in the local power option) from 12 to 33 volts.

When using a local power supply option, each channel requires a 200 ohm load. See Figure 1-1. It is necessary to do this only once for each channel string.

Model SPK300L current requirements range from 30 to 100 mA; Since, in (1), above, the power and communications signals may share conductors, it may be necessary to overcome power losses by increasing conductor size over long runs (over 1/2 mile (804 m)). Typical operating distance for one SPK300L station is 1/2 mile (.80 km), and for one SPK300L, 1/3 mile (0.53 km) using a normal # 22 AWG conductor size.

Signal

The required number of conductors to interconnect user stations is as follows (For standard unbalanced TW user stations):

# of Channels	# of Conductors
1	2 *
1	3	*	*

23***

*Using a TW power supply (and possibly operating on a TW system).

**Using a non-TW power supply.

***Using a TW power supply and operating on a TW two channel system.

Use shielded cable to interconnect user stations in areas of possible electrical interference, (areas such as those near: digital equipment, high current primary power conductors ("mains"), transformers, transmitters, and lamp dimmers).

Most two channel applications may use either standard microphone cable (for convenience) or two-twisted-pair cable (considerably less expensive than microphone cable). Standard wire size for the TW Intercom System is #22 gauge wire for interconnection. For permanent installations it is recommended that each channel should have individually shielded twisted pair of at least #22 gauge wire, such as Belden #8723 for 2 channels. Connect the shield to system common but do not tie the shield to chassis, earth or connector shell ground.

Crosstalk Control

In the TW Intercom System all channels share a common circuit ground return. Crosstalk due to common ground resistance can be lowered by reducing the common ground resistance. Reduction of ground resistance can occur as a side benefit of using shielded cable, since the shield drains can be tied together and electrically parallel the circuit ground. Another way of lowering resistive crosstalk is to "homerun" all interconnecting cables to a central or "home" location. In this configuration, the ground path is short and the corresponding ground resistance is small. Crosstalk due to mutual capacitance occurs when the signal on one wire of a twisted pair couples into the other wire. Separating the two conductors with a shield greatly reduces the capacitive crosstalk.

To reduce both capacitive and resistive crosstalk and to afford a degree of RF and electrostatic shielding, use a cable which has a shielded twisted pair for each channel. Each pair consists of a conductor for the channel, a conductor for circuit ground return and a shield around the two conductors. The shield is accessed via a drain conductor. This drain conductor and the shield can augment the circuit grounds and thus lower the ground resistance.

USER STATION CONNECTIONS

Routing the TW Intercom System cables along the same ductways and pathways as power cabling can increase the noise and hum levels.

Moisture / Contamination Protection

When using equipment in the rain, always protect the equipment with plastic covers----also, make sure all cable connectors are lifted out of the mud or snow and protected with plastic bags. Water, mud and snow in connectors can cause considerable audible noise.

Hum Prevention

Prevent inducing hum into the system by not locating user stations near hum sources such as power transformers, electrical switch panels, lamp dimmers or TV cameras. When the microphone switch is turned on, the dynamic microphone acts as a sensitive antenna for hum sources.

EN5541 - Installation, Local Power Option, RMS300 and SPK300L

The RMS300 and SPK 300 can be powered from an external (local) power supply of between 18 to 33 volts DC. the local power option, as supplied by RTS Systems, uses a power supply assembly (RTS # 9020-4425-00), which is 117 VAC, 60 Hz in, 24 VDC 400 mA out.

To modify the RMS300 or SPK300L for local power operation, do the following:

1. Remove diode D26 from the CC300 P.C. board.
2. Add J6, 4-pin jack (Calrad #30-454, RTS # 2013-0005-00), to the back panel.
3. Wire, as shown in the diagram below. Pin 1 = common, Pin 2 = external supply + (18 to 33 VDC).

Operating Controls

1. Wire PG, 4-pin plug (Calrad #30-453, RTS # 2013-0016-00) to the external supply: Pin 1 = common, Pin 2 = external supply +.
2. Plug P6 into J6 on the RMS300 or SPK300L back panel.

NOTE: If using RTS local power option kit 9002-5541-00, the external supply will already be wired to P6. Obsolete products have been discontinued and are no longer available for purchase.
