REAR PANEL INPUTS AND OUTPUTS /CONNECTIONS AND SETUP
Make all connections with the power turned “OFF” on both the subwoofer amplifier and your receiver or preamplifier!
1. Speaker Level Inputs
The Speaker Level inputs which allow this amplifier to be used in whole house distributed audio systems or with receivers that do not feature line or subwoofer outputs. You may connect either the inputs or outputs with Banana or pin connectors as well as stripped wire up to 12 gauge.
2. Line Level Inputs and Outputs
The Line Level inputs consists of a pair of stereo jacks and a single LFE RCA phono jack. Either one or both of the stereo jacks may be used. (Use a shielded, high quality subwoofer interconnect cable of appropriate length with RCA plugs on each end. Your dealer can help you select a suitable cable.) Use
the LFE jack when you are using the crossover built into your receiver or processor. The stereo inputs should be used when you wish to utilize the crossover built into the RSA-500. The Line Level outputs consist of a pair of gold plated stereo RCA jacks and a single LFE RCA phono jack. This set of outputs are unfil- tered pass through for both the Line Level and LFE input signals. They can be used to connect to a second RSA-500 amplifier or to connect back to your electronics if needed.
3. Phase Control
The Phase control on the RSA-500 is switchable between either 0˚ or 180˚. This control allows you to fine tune the performance of your subwoofer system by optimizing the blend with the main speakers. One of the positions may result in an audible increase in bass output depending upon room placement.
4. Equalizer Selection
The Equalizer switch has four settings which are labeled 1 through 4. In the “1” position, the EQ curve selected is opti- mized for the RW-5802 in-wall subwoofer. In the “2” position, the EQ curve selected is optimized for the AW-800-SW outdoor subwoofer. The position labeled “3” is for future use. The position labeled “4” is for future use.
5. Power Mode Selection
The Power Mode switch has three settings – “Trigger”, “Auto” and“On”. In the “Trigger” position, leave the Master Power switch in the “On” position and set the Power Mode switch to the “Trigger” position, then the amplifier will automatically turn itself on and off when 5-30 volts DC is detected or removed from the rear panel 1/8" Trigger jack. Tip is positive, ring is negative. There is no delay when using the Trigger function. In the “Auto” position, leave the Master Power switch in the “On” position and set the Power Mode switch to the “Auto” position, then the amplifier will automatically turn itself on and off when an audio signal is detected or removed from the rear low or high level inputs. There is a 2 second On delay and a 15 minute Off delay when using the Auto Power function. In the “On” position, the Master Power switch turns the amplifier on or off. Set the Master Power switch to the “On” position and set the Power Mode
switch to the “On” position, then the amplifier will turn itself on and off with the Master Power switch.
6. Speaker Level Outputs
The Speaker Level outputs may connected either with Banana or pin connectors as well as stripped wire up to 12 gauge.
7. AC Line Cord and Main Switch
The AC Line connection uses a detachable two-prong power cord. Insert the line cord into this jack, set the Master Power switch located above the cord to “Off”, then insert the power cord into an appropriate AC receptacle. Leave the Master Power switch off until all connections are completed. (We recommend leaving the Master Power and Power Mode switches in the “On” position for normal operation in most systems.)
CONNECTIONS AND ADJUSTMENTS
The RSA-500 is a high-performance, power amplifier with a built-in subwoofer crossover. It is designed specifically to drive one or two subwoofer modules, such as the RW-5802, to maxi- mum output without audible distortion or risk of damage. Although the amplifier’s connections and controls are simple, their use varies somewhat according to the subwoofer system’s application. Typical setup procedures are described in the following sections – one for digital systems and one for analog systems.
DIGITAL SURROUND RECEIVER OR
PROCESSOR CONNECTIONS
Today’s Dolby Digital® and DTS® digital surround receivers and processors, as well as all THX-certified models, have line-level subwoofer outputs and built-in subwoofer crossovers. If your system is built around one of these, it will almost always be best to use the RSA-500’s LFE input. This will bypass the crossover and level controls (Figure 3). Use a shielded, high quality sub- woofer interconnect cable of appropriate length with RCA plugs on each end. Your dealer can help you select a suitable cable. Be sure to go into your receiver or processor’s speaker setup menu and set Subwoofer to “On” or “Yes” in the subwoofer menu. Your receiver or processor may have additional bass management abilities beyond simply activating the subwoofer output. Consult your receiver or processor’s owner’s manual or your dealer for more information on the proper bass management settings for your system.
