Audio Output

Several of our products have an AUDIO 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.

SIGNAL AND ISOLATION

The signal available at the connector is an isolated (transformer-coupled) version of the signal being fed to the speaker inside our lockout console. 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.

The optional audio output from our systems is an RCA jack.

Signal Amplitude: approx 1Vrms w/ 5K load (output impedance approx 800 ohms)

Internal speaker: sounds whether an external amplifier is connected or not.

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.
