Several of our products have the option for an AMPLIFIER OUTPUT connection.
These outputs connect to a P/A amplifier or a mixer. The signals are line-level, meaning they will not drive a speaker (the signal needs to be amplified).
The signal connectors are RCA-style (as shown here). You may need an adapter plug (or adapter cord) to connect our lockout system your sound system.
Note: the internal speaker sounds whether an external amplifier is connected or not.
SIGNAL AND ISOLATION
The output signal is the same signal that’s fed to the internal speaker, but the output signal first passes through a built-in isolation transformer. The outer ring of the RCA jack is NOT grounded to our system. This prevents ground loops and possible noise-coupling from the lockout system’s power pack.
Signal Amplitude: approx 1Vrms w/ 5K load (output impedance approx 800 ohms)
ALTERNATIVES
We’ve had many customers who do not connect directly to an external amplifier. Instead, they put a microphone close the quiz lockout console and amplify the sound the box is making.
