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.

CONSTANT VOLTAGE DISTRIBUTION SYSTEMS
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.

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 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. 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.
Total Speaker Load Calculation
T L = SPK1+SPK2+SPK3+SPK4
T L = 2.5+2.5+2.5+2.5 = 10 Watt MAX.

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.

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.
INPUT JUMPERS - SWITCHES SETTING
The Diagram indicates the various Input Settings for this application. Some settings
may be already “Defaulted” when the Amplifier is shipped and do not need re-setting.
