For switching mains ac supply and the corresponding LED shall lit. Mains LED shallnot lit whenever only DC back up supply is connected.
2. INDICATION LEDS Indication LEDs are : Power for incoming mains AC ; Protect LED to indicate that theunit is under protection mode when the temperature rises to a maximum level and theincoming signal is muted ; Clip to show that the incoming signal level is too high,typically above +4dB ; and Signal LEDs with two levels of -40dB and -10dB.
3. AFS INDICATORS This optional feature - Auto Fault Sensing can be monitored via the LEDs. ON Ledshows the the AFS is switched on ; Fault LED indicates that the unit is diagnosed asfaulty ; and the Pilot Tone LED shall lit at intervals to indicate that a 20kHz signal isbeing sent and received to check the condition of the unit. Whenever a Pilot Tonesignal is being sent, you shall notice that the signal level LED shall lit too. This isnormal.
5. DC SUPPLY Connect back up DC supply from batteries to the connectors using approriate cablesize. Check the rating of amplifier used and the corresponding cable load-size asundersize wire may cause cable overheat and eventually lead to fire.
6. SPEAKER OUTPUT Speaker terminals are available in 4 Ohm, 70 and 100V line outputs. Use only onetype of loading, ie. do not tap 70V output together with 100V line.
Total load should not exceed the capacity of the unit’s rating. The total speakerscombined should have impedance higher than stated in the corresponding outputterminals to avoid overloading.
Do not parallel two amplifiers in order to gain higher power rating as this may causeoverloading in the event that any one of them failed. The amplifier is not designed forparallel configurations.
4. FRONT VENT Ventillation holes for hot air which is blown out from the unit. Kindly ensure there issufficient clearance for heat dissipation in your installation.

PARTS IDENTIFICATION
7. CIRCUIT BREAKERS Manual resetable circuit breakers replaces the conventional fuse replacement, thuseasier maintenance. AC circuit breaker is for the mains whereas the DC is for theinternal DC voltage. To reset, simply press the button after any fault is removed.
8. VENT FAN External cool air is drawn to the unit’s heat sink via the dual speed fan. Whenever theheatsink temperature rises to above 45 deg celcius, the fan speed shall be automaticallyincreased.
9. FAULT CONTACT Whenever a faulty condition is detected, a dry contact shall be established. This port isconnected to Amperes AX700 to enable changeover to take place. This terminal is NOin normal condition. Close contact is establised too when the amplifier is switched off.
10. PT SWITCH The AFS feature can be switched off if required. Switching it off shall render the unit torun as any other normal amplifiers. Switching it ON shall be indicated by the front AFSLEDs.
11. GROUND LIFT
12. INPUT JACKS Incoming signal to the unit is via 3 pin XLR female socket and the adjacent male jack isconnected parallel for linkage to the next unit.
13. VOLUME KNOB Output volume is adjustable from -15dB to 0 dB.
NOTES
EARTH LOOP To avoid hum or noise to the output, the chassis earth and the electrical earth should beseparated by switching Ground Lift Switch ( 11 ) located at the rear panel.
MICROPHONE INPUT The signal input to the amplifier should be line level balanced type using XLR connector.Balanced signal generally cause less noise as compared to unbalanced type. Should anunbalanced signal is to be connected, short the pin 1 and 3 together at the XLR jack.Always remember to have either both ends of cable in balanced or unbalanced mode toavoid undesired results.
SPEAKER CONNECTIONspecified. Connecting speakers to 100V line shall have load equivalent to the sum of all therating of the speakers. Connecting the same loudspeakers to the 70V line shall onlyonsume half of the power. Thereby, twice the number of speakers of the said rating can beconnected to the 70V line terminal.
SPEAKER POLARITY Speakers with ‘+’ terminal should be connected to 100V line output. Sound clarity may becompromised when anti phase connections are made and is apparent when they areinstalled closed to each other.
The sliding switch allows separation of body earthing from signal common to preventhum
Total speakers connected to the output terminals should not exceed the unit’s rating
INTRODUCTION TO AUTO FAULT SENSING (AFS)
Page 5amperes electronics .... www.ampereselectronics.com
The above block diagrams shows a general method of monitoring the condition of the power amplifiers. Somemanufacturers may have different version of sensing but in general, the above concept applies.
Amperes PX series differs from the rest by only injecting Pilot Tone at intervals. This may cause a slight delay indetection of faults but in the long run, it may prevent premature amplifier failure. At cool intervals when pilot tone isnot injected, it means that no signal shall appear and thus no loading. Continuous PT injection may result in fasterdetection, however, it means continuous loading too. Although PT is not audible ( 20 KHz ), it does present at thespeaker ends and this represents pushing the unit to work all the time even though audio signal is not injected.
Amperes identifies the setback of continuous monitoring, thereby we employ a moderate method, ie. to inject atintervals. *** request for continuous monitoring can be fulfilled upon request.
AFS forms an integral part of Amperes PX series of amplifiers and thuseliminates the need to add external module for the monitoring of the powerpack. This does not only reduces the cabling complexities but also in overallcost of installation. Connecting the PX amplifiers to Amperes AX autochangeover panel shall then form an automatic amplifier monitoring systemwhich initiates a standby amplifier takeover, thus ensuring continuous anduninterrupted paging setup.

The standard feature available in PX series can beswitched off if required, thereby rendering the unit tobe operating like any other type of normal amplifiers.
This can be done by sliding the switch to OFFposition. In this condition, the front section AFS LEDindicators shall be turned off as well.
For a complete setup, link PX amplifiers to AmperesAX700 with the contact port connected to the correspond-ing triggering terminal at the latter.
The quantity of AX700 shall be according to the number ofamplifiers available in the system. Each AX700 can caterfor 6 ut duty and 1 standby amplifiers. Cascade AX700 ifnecessary.

In rack installation, where large quantities ofamplifiers are to be installed, it is recommendedthat a ventilation panel to be mounted on top ofeach unit.
On top of the rack, a suction fan should beinstalled to draw off warm air produced by theamplifiers.
Rear panels or door of the rack should be ventedand in some cases, a suction fan should beinstalled to allow better air flow within the enclosedarea.
Optimum operating temperature of the power pack shall be below 45 ~50 deg C. The temperature measured isreferred to the exit end of the heat sinks where thermistors are located.
Do not be alarmed when the fan speed rises above normal as this is activated automatically when the internaltemperature rises above 45 deg C. Under extreme condition, the unit shall be muted when the heat rises to 85 deg C. This can be caused by accumulated heat around the units which is then blown back to the amplifiers dueto poor ventilation design... or if the output from the amplifier is shorted which causes the heat to rise exponen-tially.
