Whether you're an audio pro or setting up your home theater for the first time, this EQ makes it easy to fine-tune your sound to perfection. The REQ42 comes in black or silver and includes rack ears for optional rack mounting.

What You’ll Need:

• Rockville REQ42 Equalizer
• RCA cables
• RCA to AUX cable with phone dongle (if using a mobile device)
• Amplifier or receiver
• Passive speakers

Step-by-Step Instructions:

1. Rack Mount Installation (Optional)

• Locate the included rack ears and screws.
• Align the rack ears with the screw holes on each side of the REQ42.
• Secure each ear using the four provided screws.
• If mounting to a rack, remove the feet from the bottom of the unit to ensure a proper fit.
• Mount the unit using the four corners on your rack.

2. Understanding the Layout

• The REQ42 features a sleek design with blue LED lighting for a professional look.
• On the back, you’ll find four RCA inputs labeled: DVD, Tape, Tuner, and Aux/MP3.
• Two RCA outputs are available to connect the EQ to your amplifier or receiver.
• There's also a 3.5mm AUX input on the front for convenient MP3 or mobile device connections.

3. Connecting to Your System

• Use RCA cables to connect the EQ outputs to the RCA input on your receiver or amplifier.
• To connect an audio source like a phone:
  • Plug your dongle into your phone.
  • Use an RCA to AUX cable to connect from your phone to the AUX/MP3 RCA input on the back of the REQ42.
• For other sources (e.g., DVD player, tuner, etc.):
  • Connect the output of the source device to the corresponding input on the EQ using RCA cables.
  • Press the matching button (DVD, Tape, Tuner, Aux/MP3) under the display to select the correct source.

4. Using the Equalizer

• 21 Frequency Bands: Adjust the sliders for both left and right channels:
  • Bass (Low Frequencies): 32 – 275 Hz
  • Midrange: 250 Hz – 4 kHz
  • Treble (High Frequencies): 4 kHz – 18 kHz
• Spectrum Analyzer: Visual display shows how your EQ settings are affecting the sound.
• Buttons Under Display:
  • High/Low: Adjust the display brightness.
  • Direct: Bypasses the EQ, playing the raw audio.
  • EQ: Activates the equalizer with your custom settings.

5. Playback Demo

• Start with the EQ button off to hear your audio in its raw form.
• Then press the EQ button to activate the equalizer and hear the enhanced sound.
• You’ll notice improvements like boosted bass and clearer highs and Mids.

Important Note About Bluetooth:

• The REQ42 must process audio before it reaches your receiver.
• Bluetooth connections directly to your receiver will bypass the EQ, meaning you won’t hear any changes.
• To use the EQ effectively, connect your source devices to the EQ first using RCA cables, not Bluetooth.

Troubleshooting & FAQs

Q: Why doesn’t my EQ affect the sound from Bluetooth?

A: Bluetooth audio goes straight into your receiver, bypassing the EQ. Use RCA inputs on the EQ for it to work properly.

Q: Can I connect multiple devices?

A: Yes, the REQ42 has four RCA input options. Use the front panel buttons to switch between sources.

Q: The unit won’t fit in my rack. What do I do?

A: Remove the rubber feet on the bottom of the unit for a better fit in your rack mount.

Conclusion:

Setting up the REQ42 Equalizer is quick and easy, and it makes a big difference in your home theater sound quality.
