BALANCED MICROPHONE

IMPORTANT NOTE: The use of an unbalanced Microphone (two leads) is not recommended. For best results in a PA Application always use a Unidirectional, Low Impedance, Balanced Microphone (three leads).

CABLE LENGTH - If the distance between the Microphone and the Amplifier Input is greater than 15 ft (4.5 m) a Balanced Microphone must be used.Use a two conductor shielded wire and connect Microphone to Amplifier as per Diagram in Fig. 5A.

MICROPHONE CABLE ROUTING - The Microphone Cable should be carefully routed. Improper Cable routing will cause spurious oscillations, regenerative noises, hum, etc. that may permanently damage the Amplifier.

l Do not route cable next to power lines.

Do not route cable near or over Fluorescent Fixtures.

Do not route cable next to Speaker Wires.

Do not install cable inside Power Line Conduits.

Avoid the use of staples that may penetrate the cable.

UNBALANCED MICROPHONE

Attach the Microphone leads to the terminal strip as per diagram in Fig 5B. Be sure the cable length does not exceeds 15 Ft.(4.5 m).

MIC 1 - TELEPHONE INPUT SWITCH SELECTOR - Locate the MIC 1 - TEL Selector Switch above the Input Ter minals and Set Switch to the TEL position.

WIRING - The Amplifier is interface ready for the Telephone line in applications requiring paging from the telephone system. The Telephone line Paging Output (Tip and Ring) can be directly connected to the MIC/TEL input and to the HOT and COM as shown in the wiring diagram Fig. 6B.

CABLE - Use a two conductor twisted wire.

DO NOT GROUND THE TIP OR RING WIRE TO THE CHASSIS OF THE AMPLIFIER

VOICE ACTIVATED MUTING (VOX) - Muting of the AUX 1 or AUX 2 channels (music muting) during Paging is automatic via the Voice Activated Muting System. No contact closure for the Muting Circuit is required from the Telephone system. For additional information on the Muting operation refer to the Muting Functions section of this Manual.

25 VOLT AND 70 VOLT CONSTANT VOLTAGE DISTRIBUTION SYSTEMS - In applications requiring a large number of speakers that are located at a far distance from the amplifier a 25 Volt or a 70 Volt Constant Voltage method is most widely used.

MAIN ADVANTAGES IN USING THE HIGH IMPEDANCE METHOD

1) All speakers are connected in parallel usually on to a single speaker line.

2) The Amplifier Output Voltage is constant over a very wide range of load impedance.

3) The Amplifier Output Voltage remains practically constant if loudspeakers are connected or disconnected from the line.

4) Different acoustic power can be allocated in each area as required by using the power taps on the speaker line transformer.

5) Since the system provides a higher voltage at a lower current, resistive loss in the cable is reduced resulting in a higher efficiency.

6) Calculations of the output power needed and the speaker power requirements are simple and easily accomplished.

Fig. 13 - 70 Volt Constant Voltage System Diagram

INSTALLATION TIPS

1) Determine the amount of speakers required for the installation and their location.

2) Choose the power output needed for each speaker (typically 1.25 Watt for background music applications and 510 Watt for paging horns).

3) Add all the speaker taps wattage (see Fig. 13) and be sure that the total power needed does not exceed the Rated RMS Power Output of the Amplifier

4) Procure a jacketed, two conductor cable of at least 18 gauge.

5) Carefully route cable starting with the farthest speaker in the system and until all speakers are reached by the cable and terminating at the Amplifier location. The best cable route is determined by the individual application.

6) Connect each speaker in accordance to the power output required by selecting the corresponding Power Tap. IMPORTANT NOTE: Make sure that the unused stripped power tap wires are INDIVIDUALLY INSULATED and do not touch each other or an amplifier overload will occur.

7) Connect the speakers cable to the

25 Volt

70 Volt

and

COM

output terminals of the Amplifier, turn the system on and balance the various speakers accordingly.The selection of the Constant Voltage (25 Volt or 70 Volt) is determined by the speakers used.All speakers must operate at the same constant voltage and cannot be mixed.

LINE ATTENUATORS In installation requiring that one or a group of speakers have an independent level control a Line Attenuator can be utilized.The Fig. 13A shows the use of a PASO model VC20 - 20 Watt Attenuator used to control two speakers simultaneously. The wire colors pertain to the VC20, if other types are used follow the directions supplied with the unit.

By turning the stepped switch of the VC20 the level of speakers SPK 1 and SPK 2 can be adjusted, up or down, from 0 (no output) to the maximum output determined by the tap utilized on the speakers (in this example 2.5 Watt max.). Speakers SPK 3 and SPK 4 are not affected.

NOTE: The total power required for all the speaker or speakers to be controlled should not exceed the Power Handling rating of the Attenuator.Example: the maximum load for the VC20 is 20 Watt.

INPUT CONTROLS

MICROPHONE INPUT CONTROLS

Four separate microphone volume controls are provided to adjust the level of the respectiv e microphone inputs .Rotate control clockwise to increase volume.Set the controls to ``0'' position when the microphone inputs are not in use.

TELEPHONE PAGING LEVEL CONTROL Microphone Input 1 can be switched to Telephone Paging Input by setting the MIC/TEL Switch, located on the rear panel, to the TEL position. The telephone Paging level ca be adjusted by using the front panel control marked MIC 1/TEL.

AUX 1/CD INPUTS CONTROL

A front panel Volume Control is provided to adjust the level of the Aux 1/CD inputs.Rotate control clockwise to increase volume.This control adjusts the level of both the AUX 1 and the CD inputs.Only one input at the time should be used. Set this control to ``0'' position when the inputs are not in use.

MIC 4/AUX 2 CONTROL

Microphone Input 4 can be switched to AUX 2 by setting the MIC 4/AUX 2 Switch, located on the rear panel, to the AUX 2 position. The Microphone Input 4 and the AUX 2 level ca be adjusted by using the front panel control marked MIC 4/AUX 2.

ACOUSTIC CORRECTION

CAUTION:EXCESSIVE BOOST SETTING OF EITHER BASS OR TREBLE CONTROLS, MAY DAMAGE SPEAKERS.

BASS CONTROL

Use this control to set the tonal balance of the amplifier.The control center position, indicated by a ``0'', provides a flat response. To reduce the Bass response (bass cut) rotate control counterclockwise.To increase the Bass response (bass boost) rotate control clockwise.

Use this control to minimize Acoustic Feedback (howling) by setting the control in the CUT range 0 to -5. ALWAYS set control in the BASS-CUT position when using horn type speakers. Excessive bass response may damage the speaker's driver diaphragm.

TREBLE CONTROL

Use this control to set the tonal balance of the amplifier.The control center position, indicated by a ``0'', provides a flat frequency response.To reduce the High Frequency response (high cut) rotate control counterclockwise.To increase the High Frequency response (high boost) rotate control clockwise.USE this control to minimize possible white or hiss noise by setting control in the HIGH-CUT range 0 to -5.

TURNING THE AMPLIFIER ON

PRECAUTIONS

POWER SWITCH

DO NOT turn the amplifier On until all input and output connections have been made. MAKE SURE that all volume controls are in the ``0'' position before turning the amplifier On.Excessively high setting of the volume con-

trols may damage the speakers.Turn amplifier ON by setting the front panel POWER SWITCH to the ON position.The pilot light on the front panel should glow normally.
