Enhanced Bass Management

The AVR-3300 features superior bass management, which is responsible for ensuring that deep bass sounds do not arrive at the smaller center, front and surround speakers, at the same time ensuring that higher frequencies do not arrive at the subwoofer. The AVR-3300’s crossover fre- quency is set at 80 Hz for optimum subwoofer-to-main speakers blend.

During setup, the user can choose Large or Small according to the frequency characteristics of the system's speakersA. typical system would be configured as follows:

• Subwoofer:	ON
• Main (L/R):	SMALL
• Center:	SMALL
• Surround:	SMALL

However, some users will have large full range left and right speakers, which may even include amplified woofer sections. In this case, if the user chooses Large for the main left and right speakers, the subwoofer will only reproduce bass that appears in the LFE ( .1 ) channel. Many movie soundtracks that are 5.1 encoded actually have little or no deep bass in the LFE channel, so after a period of inactivity, the subwoofer might go into sleep/standby mode, and then miss the first few seconds of any LFE content that may appear suddenly.

The AVR-3300 allows the user to alternately select Large for the main left and right speakers and subwoofer on, and directs low bass within the main left and right channels to go to both the left and right speakers as well as the subwoofer. Bass content in the LFE channel is routed to the subwoofer. This can benefit users with large "power-tower"-type main L/R speakers with amplified woofer sections who also have a separate subwoofer in their system.

Power Supply/Power Amp Sections

The AVR-3300 features a high current, high power, all discrete power amplifier block that fea- tures identical design and identical performance for all five channels. Featuring high current wideband discrete power transistors, each amplifier channel is rated at 105 watts into 8 ohms (RMS), and has lower speaker impedance drive capability, without the need for power limiting impedance selector switching.

A large, high current 14 lb. power transformer is the heart of the power supply, with multiple stages and tight supply regulation for all stages. High current, low ESR power supply capacitors store the DC energy for delivery to the power amp block.

The power amp block features side-mounted power transistors, with a horizontal laminar finned aluminum alloy heat sink. For cooling, the AVR-3300 incorporates a smart fan system that is microprocessor-controlled. This remarkable system is designed to keep the power transistors at correct temperature levels, as well as keeping fan noise from being intrusive during quiet pas- sages.

The fan is mounted at the front of the power block with the exhaust slots on the rear panel. The fan has an off setting (passive cooling only), a low setting and a high setting (according to the
