Operation Manual, RA2400 & RA7300 Power Amplifiers REAR PANEL Page 9 RA7300 Shown A Audio Inputs There are two types of audio input connections: ● XLR type input jacks can be used to connect to the outputs of a preamplifier, receiver with preamp-out connectors or other sound source devices for the RA2400/RA7300. ● DB25 “balanced analog audio in 1-8” connector is used to connect the Datasat RS20i (home cinema audio processor) output to the RA2400/RA7300. A DB25 cable is included with the RA2400/RA7300.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 10 used. C Remote Trigger Input The remote trigger input is used for remote activation of the RA2400/RA7300 by an external device. The trigger is used to connect in a separate device in the system so when it powers on it also powers on the RA2400/RA7300. Use the Remote Trigger jack to connect a compatible preamp, source device or other product (with a 3.3-24VDC output) that that you wish to use to remotely power on the RA2400/RA7300.

J Ground Terminal Occasionally, audible hum arises when a preamplifier is connected to the RA2400/RA7300. Should this occur, running a ground wire between the preamplifier and the RA2400/RA7300 may restore noise-free operation.

Operation Manual, RA2400 & RA7300 Power Amplifiers Page 13 SPEAKER CONNECTIONS To ensure the high quality signals produced by your RA2400/RA7300 are carried to your speakers without loss of clarity or resolution, we recommend that you use high quality speaker wire. Many brands of wire are available; the choice may be influenced by the distance between your speakers and the RA2400/RA7300, the type of speakers you use, personal preferences or other factors.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 14 Using Wire to Speaker Terminals Loosen the knobs of the RA2400/RA7300 speaker terminals far enough so that the pass through hole inside the terminal is revealed. If using bare wire, pass the wire through the hole. Following the proper connection instructions for your system with regard to which terminals are used, twist the cap back to the terminal so that the connection is secured. The bare wire should make contact with the terminal metal.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 15 USING THE REMOTE TRIGGER Remote Turn On/Off Control Connections The RA2400/RA7300 features a built-in remote trigger that can be setup to automatically activate the amplifier when another device in the sound system is switched on. When Using Products Equipped With a Low Voltage Trigger Jack Switch the RA2400/RA7300’s rear panel power switch so that it is in the ON position. Then, using an accessory cable with a 3.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 16 AC POWER CONNECTION Once all audio and system connections have been made, connect the supplied power cord(s) to the RA2400/RA7300 first and then connect it to an AC power source. Note that the RA7300 uses two power cords whereas the RA2400 uses one. IMPORTANT: Make certain that the amplifier is turned off and that any auto on/off trigger device (if used) is off BEFORE connecting the amplifier’s power cord and plugging it into an AC outlet.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 17 Automatic (Trigger) On First, make certain that the connection from the RA2400/RA7300 to the controlling device is correct. Turn on the controlling device and verify that the RA2400/RA7300 is automatically activated after a short pause. Remember, this pause is intentional and is used to protect your speakers from damage while the amplifier stabilizes. You may also hear a slight relay click during start up and this is also normal.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 18 CARE AND MAINTENANCE Cleaning If the RA2400/RA7300 becomes dirty, wipe it with a clean, soft, dry cloth. If necessary, first wipe the surface with a soft cloth slightly dampened with mild soapy water followed by a fresh cloth dampened with clean water. Wipe dry immediately with a dry cloth. NEVER use benzene, thinner, alcohol or any other volatile cleaning agent. Do not use abrasive cleaners, as they will damage the finish of the metal parts.

Potential Ground Loops in a Complex A/V (audio visual) System Suggestion #1: To determine if a cable TV connection is responsible for the hum, first turn all components off. ● Disconnect the cable TV feed to your sound system at the first place where it connects to the components.
Operation Manual, RA2400 & RA7300 Power Amplifiers Page 21 ● The ultimate solution to this type of problem is to re-wire your house with an isolated, star typegrounding configuration. We recognize, however, that this may be impractical and expensive. In some cases, the use of an approved AC Power Isolation Transformer of sufficient capacity may solve this problem.
