5 Real Time Power Protection (R.T.P.P.) allows for thegreatest power output under all load conditions. Whenoutput reaches an unsafe level it will be reduced, unlikecurrent limiting which often causes premature protectionor failure to protect at all. To get a better understanding of the Punch let’s t...

6 B+/GND Power Connector LED Power Indicator REM Connector Four (4) custom, round, hex screws included in the acces-sory pack hold the unit in place. These screws are coveredwhen the end caps are installed. The Punch 4-Channel is turned on by connecting the blueremote turn-on wire to the source unit...

8 The amplifier’s signal input, female, RCA jacks should beconnected to the source unit’s signal outputs with high-quality RCA cables. The connectors have been plated ingold to eliminate the possibility of corrosion that can causesignal deterioration. These pass-thru connectors allow you to daisy-ch...

For safety, disconnect the battery ground cable priorto beginning the installation process. 6. Never run wires underneath t...

MOUNTING AND LOCATION The mounting location and position of the Punch 4-Channel will have a great effect on its ability to dissipatethe heat generated in normal operation. The Punch 4-Channel has a heatsink designed for heat dissipationand internal shutoff circuitry to avoid overheating. It isreason...

2. For the Punch 4040, place the protective boot onto the wire. Insert the wire into one end of the fuse holderso that the insulation is just inside the crimp area asshown in the diagram. Crimp the wire in place with thenotched portion of a crimping tool. Cover the crimpedarea with the protective bo...

14 Punch 4-Channel amplifiers are rated for safe operationinto loads of 2 Ω , or greater in stereo mode or 4 Ω in bridged/mono configurations. The primary loads on anyamplifier come from directly connected speakers withoutusing capacitors. The measured resistance for each sideshould not be less than...

ProblemAmplifier will not play – Remote turn-on light is off. Solution1. Check the DC voltage at the amplifier's B+ terminal with a voltmeter. The voltage should measure be-tween 11.5V - 15.5V. If voltage is not found, check the battery, fuse, fusehousing and wire connections. Fix, repair, or replac...

DYNAMIC POWER MEASUREMENTS About the Dynamic Power Measurements The Audio Graph PowerCube is a test instrument used to measure the output of an amplifier in accordance withIHF-202 industry standards. The IHF-202 standard is aDynamic power measurement and was developed as ameans of measuring power in...

A 4 ohm speaker may experience a drop in impedance 4-6 times lower than its nominal (printed) impedance. Aspeaker will also create phase shifts in the signal that ispassed through it. These phase shifts happen becausea speaker is an inductor (voice coil) and a capacitor(compliance of the surround/sp...

30 What is an Amplifier? An amplifier by definition is a voltage generating device,recreating the signal which is input to in an identical but amplified form. It will be connected to a reactive load (the speaker). The impedance of this load and phase of thesignal passing through the load will vary, ...
