11.3 AC 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
11.4 OUTPUT 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 .
11.5 SYNC-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).
