PRELIMINARY
The MA models’ amplifier power-up delays are approximately
• 10 seconds for 70 V or 100 V output, 8 seconds to hear the relay click
• 8 seconds for 4 ohm or 8 ohm output
Wiring for 4 ohm or 8 ohm speakers (MA models)
The maximum power output when an MLS 304MA or MLS 406MA is wired
for 4 ohm or 8 ohm speakers is 20 watts per channel.
1. Flip the toggle switch down (Direct) to select 4 ohm or 8 ohm connection.
2. Use the appropriate wiring for the load as shown in the following
illustrations.
Two 8 ohm speakers wired in
parallel equal a 4 ohm load.
