Connecting speakers to your REDBACK A4395 500W Mixer Amplifier is straightforward. Here's how to ensure a proper setup:
-
Speaker Connections:
- For speakers with a total impedance between 4 and 16 ohms, connect them to the terminals labeled "4-16Ω" on the amplifier's rear panel.
- If your speakers use 70V or 100V line transformers, connect them to the corresponding terminals on the rear.
- Crucially, make sure the total power handling of all connected speakers does not exceed the amplifier's 500-watt output to prevent damage.
- When working with speakers that have line transformers, you'll need an impedance meter. A standard multimeter won't provide an accurate reading.
-
Wiring for 70V & 100V Line Speaker Systems:
- When using multiple speakers in a single circuit, speakers with line-matching transformers are necessary. This setup prevents issues related to parallel connections and cable signal loss.
- To calculate the total wattage load on the amplifier, add up the primary tap ratings of all the line transformers.
-
Measuring 70/100V Line Speaker Impedance:
- Use an impedance meter to determine the AC resistance of your speaker network. A regular multimeter measures DC resistance, which isn't suitable for this purpose.
-
Impedance Values for 70V and 100V Line Transformers:
- Consult the REDBACK A4395 user manual for a table detailing the impedance values at various load settings for speakers equipped with 70V and 100V line transformers.
Following these steps will help you connect your speakers correctly and optimize the performance of your REDBACK A4395 500W Mixer Amplifier.
