1. SAFETY INSTRUCTIONS

1. Read Instructions — Read all the safety and operation instructions before operating the UP4000.

2. Retain Instructions — The safety and operating instructions should be kept for future reference.

3. Heed Warnings — Follow all warnings on the UP4000 and in these operating instructions.

4. Follow Instructions — Follow all operating and other instructions.

5. Water and Moisture — Do not use the UP4000 near water – for example, near a

bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, etc.

6. Ventilation — This UP4000 should be situated so that its location or position does not interfere with its proper ventilation. For example, it should not be situated on a bed, sofa, rug, or similar surface that may block any ventilation openings, or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air through ventilation openings.

7. Heat — Locate the UP4000 away from heat sources such as radiators, or other devices which produce heat.

8. Power Sources — Connect the UP4000 to a power supply only of the type described in these operation instructions or as marked on the rear panel.

9. Power Cord Protection — Route power supply cords so that they are not likely to be walked upon or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit the UP4000.

10. Object and Liquid Entry — Do not drop objects into or spill liquids into the inside of the UP4000.

11. Damage Requiring Service — The UP4000 should be serviced only by qualified service personnel when:

A. The power-supply cord or the plug has been damaged; or

B. Objects have fallen, or liquid has spilled into the UP4000; or

C. The UP4000 has been exposed to rain; or

D. The UP4000 does not appear to operate normally or exhibits a

marked change in performance; or

E. The UP4000 has been dropped, or its chassis damaged.

12. Servicing — The user should not attempt to service the UP4000 beyond those

means described in this operating manual. All other servicing should be referred to the Mackie Service Department.

13. To prevent electric shock, do not use this polarized plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.

Pour prévenir les chocs électriques ne pas utiliser cette fiche polariseé avec un prolongateur, un prise de courant ou une autre sortie de courant, sauf si les lames peuvent être insérées à fond sans laisser aucune pariie à découvert.

14. Grounding or Polarization — Precautions should be taken so that the grounding or polarization means of the UP4000 is not defeated.

15. This apparatus does not exceed the Class A/Class B (whichever is applicable) limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications.

ATTENTION —Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant las limites applicables aux appareils numériques de class A/de class B (selon le cas) prescrites dans le règlement sur le brouillage radioélectrique édicté par les ministere des communications du Canada.

WARNING — To reduce the risk of fire or electric

shock, do not expose this appliance to rain or moisture.

2. INTRODUCTION

The UP4000 Series Power Amplifiers are designed for continuous duty in speech, music, paging, and sound reinforcement applications in churches, schools, offices, and other venues demanding high performance, flexible features, and rugged dependability.

Two discrete inputs with priority are provided. The main program input is actively balanced and terminated to a barrier strip connection on the rear panel. The second input is unbalanced and terminated to a single RCA connector. A contact closure will give priority to the balanced input by muting the unbalanced input. The unbalanced input features a parallel output and 0 dB/20 dB sensitivity switch.

Output modes include 4Ω constant impedance and 25V, 50V, 70V, and 100V constant voltage. The smart output stage is fully protected against permanent damage caused by overloading, shorts, and extreme temperatures. Activation of the overload protection circuit turns on 18 VDC (300mA) power at a barrier connector on the rear panel, which may be used to drive a relay or indicating LED. The UP4000 Series will operate on either 115 VAC or 230 VAC, 50/60Hz, as determined by the Voltage Selector switch, and supplied by a detachable IEC power cord. Insulated terminals to connect a backup 24 VDC battery are provided on the rear panel. Switchover to DC is automatic. A programmable stand-by mode allows the amplifier to be turned on remotely with a contact closure.

The front panel provides a Master volume control, and Low and High EQ controls. The control knobs can be removed for security, and their recessed shafts covered with the supplied inserts. LEDs indicate power, stand-by mode, signal present at the output, peak, and output overload. 12 dB/octave Low and High shelving equalization with up to 12 dB of boost or cut at 100Hz and 10kHz can be applied to the output signal.

Accessories include a rack mounting kit.

The

indicator lights when the amplifier is in standby mode. Note: Standby mode is disabled by default. An internal jumper (J1 on the input board) must be changed to enable standby mode. See "Internal Settings" on page 8.

The

OVERLOAD

indicator lights when the amplifier is operating in overload, a condition generally caused by a problem on the speaker line. When the amplifier is switched on, the

OVERLOAD

light comes on for a few seconds. This is normal and does not indicate a problem.

The ON indicator lights when the UP4000 is

POWER INPUT

provides a means to connect an external 24 VDC power supply or battery as an alternative or backup power source. The UP4000 Series seamlessly switches to the backup supply if there's an AC power loss. When both AC power and 24 VDC power are connected, the DC power is switched off.

Note: The unit is not equipped with battery charging capability.

The

D.C. FUSE

protects the DC power input to the amplifier circuit. Replace with the same type fuse only.

POWER OUTPUTS

are screw-terminal connections for connecting speakers to the 4-ohm, 25V, 50V, 70V, or 100V outputs.

WARNING: To prevent the risk of electric shock, never touch the bare wires coming from the output terminals of the amplifier when it is switched on. When all connections have been made, insulate the output terminals of the amplifier using the protective cover provided.

Constant-Impedance Output

The total impedance of the speakers and cable connected to the "4Ω" constant-impedance output should be 4 ohms. Connect the "4Ω" terminal to the "+" (HIGH) speaker terminal, and the "0" terminal to the "–" (LOW) speaker terminal.

Constant-Voltage Output

In a constant-voltage system, each speaker must be equipped with a line transformer having an input voltage equal to that of the line (e.g., 25V, 50V, 70V, or 100V). Typically, these line transformers have selectable power taps (i.e., 2.5W, 5W, 10W) for connecting to the constant-voltage line. CAUTION: The sum of the wattage values of the speakers must not exceed the output power of the amplifier.
