Connections, Indicators, and Controls

E Audio output connector — Insert a 3.5 mm, 5-pole captive

screw connector into this connector for a balanced or unbalanced 1 kHz sine wave audio tone.

NDo not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could pull out.

CAUTION

For unbalanced audio, connect the sleeve(s) to the ground contact.

DO NOT connect the sleeve(s) to the negative (-) contacts.

F Power connector — Plug the external 12 V power supply into this 2-pole captive screw connector. The power supply is included with the unit. Figure 7 shows how to wire the connector.

CWhen connecting the power supply, voltage polarity is extremely important. Applying power with incorrect voltage polarity could damage the power supply and the BBG 6 A. Identify the power cord negative lead by the ridges on the side of the cord or the black heat shrink wrapping around it.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

As an alternative, you can use an Extron P/S 100 Universal

12 VDC Power Supply (part #60-357-01), which can power up to ten BBG 6 As or other Extron 12 VDC devices using only one AC power connector.

G Version label — Differentiates the standard (NTSC and PAL signals) versus Japanese (BBG 6 A J, NTSC signals only) versions of the BBG 6 A.
