5. Setup

5.1 Speaker Connections

The RX4208 features 5-way binding posts for speaker connections, allowing for bare wire, spade connectors, pin connectors, or banana plugs.

1. Ensure the receiver is powered off and unplugged from the AC outlet.
2. Connect the positive (+) terminal of your left speaker to the LEFT (+) terminal on the receiver.
3. Connect the negative (-) terminal of your left speaker to the LEFT (-) terminal on the receiver.
4. Repeat steps 2 and 3 for the right speaker, connecting it to the RIGHT (+) and (-) terminals.
5. Ensure all connections are secure and that no stray wire strands are touching other terminals, which could cause a short circuit.

5.2 Audio Source Connections

Connect your audio components using RCA cables.

1. Connect the RCA output cables from your CD player to the 'CD' input jacks on the receiver (Red to Red, White to White).
2. For other auxiliary devices (e.g., media player, cassette deck), connect their RCA outputs to the 'AUX' input jacks.
3. For a turntable, connect its RCA output cables to the 'PHONO' input jacks. If your turntable has a built-in pre-amplifier, it is generally recommended to connect it to an 'AUX' input to avoid potential signal overload and distortion.

5.3 Antenna Connections

Connect the supplied antennas for AM and FM reception.

• FM Antenna: Connect the supplied FM wire antenna to the 'FM ANTENNA' terminal. Extend the wire for best reception.
• AM Antenna: Assemble the supplied AM loop antenna and connect its two wires to the 'AM ANTENNA' terminals. Position the loop for optimal AM reception.

6. Operating Instructions

6.1 Basic Operation

1. Power On/Off: Press the Power button on the front panel or remote control.
2. Input Selection: Use the Input Selector knob or buttons on the front panel/remote to choose your desired audio source (CD, AUX, Phono, Tuner).
3. Volume Adjustment: Rotate the Volume knob or use the Volume +/- buttons on the remote to adjust the sound level. Start at a low volume and increase gradually.

6.2 Tone Controls

Adjust the sound characteristics to your preference:

• Bass/Treble: Use the respective knobs on the front panel or buttons on the remote to increase or decrease bass and treble frequencies.
• Tone Direct: Press the 'Tone Direct' button to bypass the bass and treble control circuits. This provides a flat frequency response, often preferred for pure audio reproduction.

• Preset Stations: To store a station, tune to the desired frequency, then press 'Memory' followed by a preset number button (1-30). To recall a preset, simply press the corresponding preset number button.

7. Maintenance

Proper care ensures the longevity of your receiver.

• Cleaning: Wipe the exterior surfaces with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents.
