Falcon 15 manual Fm Version Description, 11.3AC CONNECTION, 11.4OUTPUT CONNECTOR

FM VERSION DESCRIPTION ENG

11.3AC CONNECTION

The Falcon 15 uses a power entry module with AC switch just closed to the IEC power cord receptacle. It can operate on 110 or 240 VAC, 50/60 Hz AC mains voltages. If the unit is to be used with a mains voltage different to that for which the unit is supplied, set the voltage change-over switch, which is placed inside the box, closed to the AC transformer.

The power supply socket has an integral fuse drawer containing the AC power fuse and a spare, both of the same value.

-for 220/230 V AC the fuse is rated at 500 mA T

-for 110/115 V AC tension the fuse is rated at 1 A T

11.4OUTPUT CONNECTOR

Depending on the version, Output BNC connector (50 Ohm impedance) features Stereo Composite Signal (MPX) and/or RDS signal (with or without signals injected from Aux 1 and 2 mixed into).

You can adjust the overall output level through the menu (MPX Level control in the MPX MODULE SETUP page) in the – 9 dBm to +15dBm range. Factory preset: 0 dBm (2.2 Vpp).

Output connector can provide a reference tone consisting of a 500 Hz / 0 dBm sinusoidal signal. This tone corresponds to the maximum frequency deviation. To enable it, see par.

12.3.3.

11.5SYNC-IN AND SYNC-OUT CONNECTORS

Sync In:

It is disconnected (not used)

Sync Out

This TTL-level (5Vpp) 19 kHz square wave output can be used as the reference signal for any SCA generator that operates at 57 kHz or other multiple of the 19 kHz pilot frequency. Using the 19 kHz clock from the Falcon 15 makes it much easier to phase lock the external signal to the pilot frequency. This is extremely helpful in order to remove intermodulation components. For RDS coders, this feature is also very useful.

The Sync Output is disabled by default (see par. Output Sync menu 12.3.5 for enabling).
