FUNCTION SWITCHES AND JUMPERS

UNDERSTANDING THE INPUT FUNCTIONS

VOX AND MUTE - The Amplifier provides an independent VOX and MUTE SYSTEM

FUNCTION SOCKETS - EACH INPUT IS PROVIDED WITH A VOX (V1) AND A MUTE (M1) SOCKET.

INPUTS VOX AND MUTE FUNCTION - All Inputs provide a VOX SEND and a MUTE RECEIVE functions. The VOX and MUTE functions are SWITCHED-ON, on each Input, by Internal Jumpers provided for each Input.The VOX BUSS SEND (V1) and the MUTE BUSS RECEIVE (M1) can be independently SWITCHED-ON or OFF to suit the application requirement.

Fig. 8 - Any Input VOX and MUTE Functions

JUMPER SETTINGS - The VOX and MUTE Functions are

SWITCHED-ON or OFF by setting the JUMPERS on the VOX (A) and MUTE (B) SOCKET. See Fig. 8A.

The SOCKETS are located on the Main PCB inside the Amplifier as shown on the SWITCHES and JUMPERS LOCATION DIAGRAM in this Manual. Each Socket is identified by an ID NUMBER and the FUNCTION and DEFAULT settings are listed on the FUNCTION SWITCHES and JUMPERS DEFAULT SETTING TABLE in this Manual.

TO SET: Lift the Jumper and reset as required. making sure that the JUMPER is properly positioned over the two shorting pins.

The VOX JUMPER has two positions: OFF, and V1 The MUTE JUMPER has two positions: OFF, and M1

The figure below shows how the VOX 1 Logic Switch is switched ON and the MUTE 1 Logic Switch is SWITCHED-OFF by moving the Jumpers as indicated. When the Input is activated by a Source signal the corresponding VOX Signal is sent to the V1 BUSS. When the VOX 1 is activated by any Input the MUTE Signal is present on the MUTE 1 BUSS and it will MUTE any Input with the MUTE M1 turned on.

SETTING THE VOX AND MUTE JUMPERS

Fig. 8A - VOX and MUTE Sockets

IMPORTANT NOTE

BE SURE NOT TO SET BOTH THE VOX AND CORRESPONDING MUTE ON THE SAME INPUT OR THE INPUT WILL MUTE ITSELF WHEN ACTIVATED.

INSTALLATION AND WIRING

CONNECTING TO AN EXTERNAL EQUALIZER

The Amplifier is equipped with an External Equalizer Link to allows the use of an External Equalizer for applications requiring

Frequency Selective Acoustic Correction

. The Amplifier is furnished with the two jacks of the Link bridged by a SELECTOR SWITCH. When the EQ LINK Switch (REFERENCE 21) is the EXTERNAL position the internal Preamplifier to Amplifier Link (Reference 21) is broken allowing the insertion of an External Equalizer.

INSTALLATION TIPS

1) Use high quality, short length audio cables and position the Equalizer in close proximity to the Amplifier. Avoid mounting the EQ on top of the Amplifier unless is Rack mounted.

2) Be sure that the Amplifier input controls and the EQ level control are set at zero prior to turning the system On.

3) The Amplifier TONE BY PASS SWITCH (Reference 18) should be set to ON ( linear response position).

4) Carefully adjust the EQ Level Control to avoid distortion caused by excessive signal boost.

5) Follow the instructions supplied with the Equalizer.

WIRING

To connect to an External Equalizer use two (2) single conductor shielded audio cables terminated in a single prong phono plug on both ends.

NOTE:

When calculating the Wire Resistance for each run using a two conductor Wire the wire Resistance should be doubled.

EXAMPLE: The Total Resistance of a 1000 Ft. run of a AWG 24 two conductor Wire is:

25.67 X 2= 51.34 Ohm

REMOTE VOLUME CONTROL

The Amplifier features a Remote Volume Control Capability:The INPUT 3 (AUX

1) Remote Volume (Reference 10). A 10 K ohm Potentiometer is required. Mount the 10 K Pot on a suitable Wall Plate or any other convenient surface and connect to the Amplifier RVC Terminals as shown in the Diagram. The Paso Model RVC10W Decora Style Remote Volume Control may be used.

INPUT 3 (AUX 1) OPERATION

When connected the Remote Volume adjusts the INPUT 3 (AUX 1) Level only. Usually this input is utilized for the Music Source (Sat. Receiver, CD Player, etc.).

CABLE

To connect the Remote Control to the Amplifier use a two conductor wire not less than AWG 20. While the Remote Volume System uses DC rather than audio caution should be exercised in the layout of the wire. Always avoid routing next to power lines. If the total wire resistance exceeds 3 K ohm the Volume may not go down to zero.

OUTPUT CONNECTIONS

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.

CONSTANT VOLTAGE DISTRIBUTION SYSTEMS

Fig. 28 - 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. 28) 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. 28A 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.

RESTAURANT/DINER WITH MUSIC AND JUKEBOX - APPLICATION DATA 126

APPLICATION

This Note illustrates a typical installation in a Restaurant/Diner/Lounge using Background Music and a Jukebox. The Background Music can be automatically interrupted when the Jukebox is activated. The Background Music is then automatically restored once the Jukebox stops playing. This built-in feature of the DMA Amplifier eliminates the need of any external device.

PAGING MICROPHONE

PRIORITY PAGING MICROPHONE - A Low Impedance Dynamic Microphone can be connected to the Amplifier INPUT 1. The Microphone Input can be set to provide

Priority Paging

over the Music Program but not the Jukebox when activated.

Optionally Paging may be generated from the Phone system if desired.

PAGING FROM THE PHONE SYSTEM

PRIORITY PAGING FROM THE PHONE SYSTEM - Paging may be generated from a Phone System by using the TEL INPUT of the Amplifier. The TEL INPUT can be set to provide

Priority Paging

over the Music Program but not the Jukeboxwhen ctivated.

The TEL INPUT provides a 600 ohm Transformer balanced Phone interface.

MUTE DELAY

The Jukebox Configuration utilizes the VOX/MUTE 1 Buss. In order to prevent the premature JUKEBOX/MUSIC SOURCE switching (the Music Source cuts-in while the Jukebox is active) a MUTE TIME DELAY TRIMMER is available on the Rear panel to increase the MUTE DELAY as necessary. The MUTE DELAY can be adjusted from 3 to 60 Seconds. EXAMPLE: If the Jukebox is playing and the Tune has a long pause or the long pause while the Jukebox is cycling between CD’s it is possible that the Music Source (Background Music) may cut-in causing annoying and unwanted

chatter

while the Jukebox is still active. To prevent this problem the MUTE TIME DELAY TRIMMER should be adjusted accordingly.

JUKEBOX REMOTE VOLUME CONTROL

A Jukebox Remote Volume Control may be provided to adjust the Output Level independently from the Background Music Source.The Jukebox Music Level should be set in accordance to the ambient noise which may change during peak business hours. The AUX 1 Input (used for the Jukebox) is equipped with a Remote Volume Control Feature. Use the optional PASO Model RVC10W (10K) Volume Control mounted on a single gang plate.

MUSIC ON HOLD

The Zone 1 Amplifier provides a separate 600 ohm Transformer Balanced Music on Hold Output for the Telephone system. If the Zone 1 Input Selector Switch is set to Input 4/aux 2, the MOH Output receives only the PROGRAM from the the MUSIC SOURCE without Paging or the Jukebox interruptions.

ZONE 1 2 WATT - 8 OHM OUTPUT

The ZONE 1 Output may be used to cover small area with MUSIC ONLY without interruption from the Microphone or Phone Paging or the music from the Jukebox. The Program Source for THE 2 Watt Amplifier may be independently selected through Internal Jumpers (see Diagram). Output Level may be also independently adjusted by the separate Level Control.

ZONE 1 SPEAKERS

The Wiring Diagram shows the connection of up to 4 (8 ohm) Speakers for the Zone 1 - 2 Watt Amplifier. When 4 Speakers are used each Speaker Output will be a 1/2 Watt.
