Remote turn on is easily accomplished by either audio or AC trigger sensors. If focused power is required a optional Hi-pass filter is incorporated. Master remote level control is easily done via an external 10k poteneometer and a line out makes easily to daisy chain amplifiers. The PA1001G can be used for many in many ways ranging from boardroom, restaurant, commercial paging and back ground music applications. 2 1 3 5 6 7 4 Front Panel 1. Power Switch This switch turns the AC Mains power to the amplifier on or off. 2. Power LED Illuminates Red when the power switch is depressed. Red means the amplifier has AC mains power to the unit and is standby or sleep mode. When LED is Blue the unit is active and will pass audio. 3. Limit LED The Limit LED will illuminate Red if either channel of the PA1001G reaches maximum output power or if a fault is detected with in the amplifier. The PA1001G features a true limiter circuit which help prevents the amplifier from hard clipping or from being over driven. An occasional flash of the LED is ok, if the LED is on continuously reduce the input level of the amp. After the reducing the input level and the Limit LED remains on, recheck the load connections to the amp. 4. Signal LED The Signal LED illuminates Green if there is audio signal present at the input of the amp. 5. Input Gain The Left and Right rotary control varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and counterclockwise to decrease the signal level. Note: This post the RCA mix level control. See mix function below. 6. Bass Control Normally set at the 12 o'clock position unity gain, rotating clockwise will increase (boost) bass frequencies to a maximum of +6dB at 100Hz. Rotating counterclockwise from the 12 o'clock position will decrease (cut) bass frequencies to a maximum of -6dB at 100Hz. Note: This feature affects both the Left and Right channels the same. 7. Treble Control Normally set at the 12 o'clock position unity gain, rotating clockwise will increase (boost) treble frequencies to a maximum of +6dB at 10kHz. Rotating counterclockwise from the 12 o'clock position will decrease (cut) treble frequencies to a maximum of -6dB at 10kHz. Note: This feature affects both the Left and Right channels the same. 1 5 11 2 7 8 9 6 4 3 10 Rear Panel 1. IEC AC Receptacle Connect this grounded power cord to 100VAC - 240VAC 50/60Hz circuits only. Serious damage may result otherwise. 2. AC Mains Fuse For 100v - 240v 50Hz - 60Hz operation use Slow Blow T1.6AL 250v, 5mm x 20mm. Note: Fuse is internal and should only be changed by a qualified technician. 3. UNSWITCHED OUTLET The un-switched outlet provides power for other devices such as video projectors, CD players or laptop computers. This AC outlet is live all the time as long as the power cord is plugged into a live duplex outlet. Keep the total power draw below 500W. This outlet can also be used to remotely turn on the PA1001G. See AC Sense Trigger for more detailed information (page 9). 4. RCA Input Unbalanced signals are accepted when using the Left and Right RCA connectors. These inputs are electrically summed into a mono signal. 5. AC Fault LED This LED will illuminate Red if a fault has occured with the AC spike supression circuity. Usually cause for this is a lightning strike, causing a voltage surge. The AC Unswitched outlet may still function but there may be no AC surge or Spike supression protection for the product connected to the outlet. It is recommended to have the amplifier looked at by certified technician. 6. Balanced Input Connections Left and Right balanced input signals can be accomplished by wiring the removable Phoenix type connector per the labeling on the rear of the amp. Note: The middle pin is the common ground connection for both Left and Right input ground. For unbalanced signals connect the (–) and (GND) pins together. 7. Speaker Connections A removable Phoenix type connector is supplied to connect your speakers to the PA1001G. It is recommended to use 16guage wire or higher for connection to the speaker. Note: Do not overload the amp by connecting to many speakers to the amp. Four ohms per channel is the maximum load. 8. Four Position Dip Switch Assignment Switch 1 - Sense On/Off, this switch activates the PA1001G remote turn on sensing circuits via either Audio or AC trigger. When the switch is in the “DOWN” position, all trigger circuits are bypassed. The only way to turn the amp On or Off is via the mains AC Power Switch located on the front panel. When in the “UP” position either the Audio or AC Sense turn on Triggers is activated. See switch 2 for selection. Switch 2 - Sense AC / Audio, when Switch 1 is in the “UP” position you may select the type of remote turn on trigger. Note the AC Mains Power Switch must also be in the “on” position. AC Trigger - This switch function is used if you have an external device is plugged into the Unswitched AC outlet and you want that device to turn on or activat...
