I NTRODUCTION The Punch 360. 6 , is a 360 watt, 6 channel amplifier with integrated features for accommodating “single amplifier” system designs. Built into the amplifier are four internal XCards and a Signal Switching Network. These features simplify signal processing and enable custom signal distribution for each set of channels. Also integra[...]

T ECHNICAL D ESIGN F EA TURES – 2 – ◆ T RANS•ANA ( TRANSconductance Active Nodal Amplifier) The TRANS•ANA ( TRANS conductance A ctive N odal A mplifier) is a circuit that allows the audio signal to pass through the amplifier at low voltage . The signal is directly level-shifted to the fixed high voltage rails via a pair of driver transist[...]

◆ DSM (Discrete Surface Mount) Technology The DSM (Discrete Surface Mount) manufacturing process combines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manufacturer to have invested millions into this process. DSM components differ from conventional discrete components in diff[...]

◆ MOSFET Devices Rockford Fosgate is one of the few manufacturers in the sound community to utilize MOSFET devices in both the power supply and the output stages . MOSFET ( M etal O xide S emiconductor F ield E ffect T ransistor) devices offer several important inherent advantages over the 30 year old technology of bi-polar design. These advantag[...]

360. 6 D ESIGN F EA TURES 1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch amplifier dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs. 2. End Caps – The unique end caps conceal the wiring and input [...]

8. Input Sensitivity Controls – The input level controls are preset to match the output of most source units. They can be adjusted to match output levels from a variety of source units. 9. Bass EQ Control – The Bass EQ allows a narrow band adjustment of up to +18dB centered at 45Hz. The bass boost can be bypassed by turning the control to its m[...]

M OUNTING L OCA TION The mounting location and position of your amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. The design of our cast aluminum heatsink serves to easily dissipate the heat generated over a wide range of operating condi- tions. However, to maximize the performance of your am[...]

B A TTERY AND C HARGING – 9 – Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend checking your alternator and battery condition to ensure that the electrical system has enough capacity to handle the increased load of your stereo system. Stock electrical systems which are in good condition shoul[...]

– 10 – Mount the fuseholder within 18" of the battery using two (2) #8 screws. Disassemble the fuseholder. You should have 2 black plastic end caps, 2 gold-plated fuse clips, a plastic spacer and the fuseholder body. Trim the amplifier power cable to reach the fuseholder and strip the wire 3/8". Slide one of the end caps over the wire[...]

8. Connect the source signal to the amplifier by plugging the RCA cables into the input jacks at the amplifier. 9. Connect the speakers. Strip the speaker wires 5/8". Insert the bared wire into the speaker terminal and tighten the set screw to secure into place. Be sure to maintain proper speaker polarity. DO NOT chassis ground any of the spea[...]
