INSTALLATION AND WIRING
INPUT CONNECTIONS
AUXILIARY INPUT
The AUX input is provided for high level program source. The out­put from a Satellite Receiver Tuner, Tape Cassette Deck, CD Player or other high level program source may be directly connect­ed to this input.
AUX INPUT SENSITIVITY ATTENUATOR
The AUX Input is equipped with a Sensitivity Attenuator that allows the interface of the AUX Input with Devices having a wide range of Output Levels.
TYPICAL OUTPUT LEVEL OF MUSIC DEVICES: Satellite Receivers = 1 to 5 Volt Digital Tuners/Receivers = 100 to 300 Mv CD Players/Changers = 2 to 3 Volt Tape Decks = 500 to 700 Mv
By adjusting the Input Sensitivity to the level that matches the device used the correct interface with the Amplifier is achieved resulting in lower overall distortion and better frequency response characteristics.
SETTING THE AUX INPUT ATTENUATOR
Connect a Music Source to the Amplifier. Turn Attenuator (rear panel) fully counterclockwise. Tu r n AUX Front Panel Control to about 2 o’ clock. Switch Amplifier and Music Source ON. Turn rear panel Attenuator Control clockwise slowly until desired Output Level is achieved. Adjust AUX Front Panel Level Control Up-Down as desired.
STEREO SUMMING
Since most Music Source Devices provide a Stereo Output the Amplifier is equipped with two Jacks for the AUX Input (L and R). The two Inputs are internally buffered and electronically mixed to Mono. This system ensures that the Music Device is properly loaded and that the Stereo Signals are correctly summed (L+R) to Mono without distortion.
CABLE
To connect the music source devices to the AUX Input use two sin­gle conductor shielded audio cable terminated in a single prong phono plug on both ends.
CAUTION: TO PREVENT POSSIBLE DAMAGE TO SPEAKERS OR THE AMPLI-
FIER ALL INPUT CONNECTIONS MUST BE MADE WITH THE AMPLIFIER OFF.

INSTALLATION AND WIRING
OUTPUT CONNECTIONS
SERIES - PARALLEL - SERIES PARALLEL INSTALLATIONS
In applications requiring a small number of speakers, the speaker line can be connected to the 8 ohm impedance output of the Amplifier. The speakers available should be wired either in series, parallel or series parallel combinations to match the output imped­ance of 8 ohm. Impedance matching is essential to provide maxi­mum power transfer and efficiency.
CAUTION
1) If the total load impedance of the speakers used is greater than 8 ohm less then the total power of the amplifier will be transferred to the speakers.
2) If the total load impedance of the speakers used is lower than 8 ohm the mismatch will cause an overload of the output and may trip the Amplifier Overload Protective System.
Fig. 18B - Series-Parallel Connection Diagram
PRECAUTIONS: THE AMPLIFIER UTILIZES A BALANCED SPEAKER OUTPUT SYSTEM ON BOTH 8 OHM AND 25/70
VOLT SYSTEM OUTPUTS.
1) DO NOT CHASSIS GROUND THE SPEAKER OUTPUT TERMINALS.
2) MAKE SURE THAT THE SPEAKER WIRES ARE NOT SHORTING OUT AT THE TERMINAL STRIP.
3) MAKE SURE THAT THE OUTPUT TERMINALS PROTECTIVE COVER IS REPLACED AFTER ALL THE SPEAKER WIRING AND CONNECTIONS ARE COMPLETED.
4) PRIOR TO THE INSTALLATION AND WHEN USING THE 70 VOLT LINE SYSTEM CHECK THE LOCAL ELECTRICAL CODES REGULATING THE WIRING OF THE SYSTEM.

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. 19 - 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
or
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.
