MASTERCALL ™ REMOTE RADIO STATION MONITOR
Description
The Mastercall Remote Radio Station Monitor provides media market observers with remote access to
radio station broadcasts for monitoring purposes.
Standard telephone dial-up access is used to establish a connection to the radio station broadcast audio.
Connection
• Line 2 of Mastercall is connected to the telephone line.
• Audio out (‘line’ level, 600 mV RMS nom.) from the radio is connected to the RCA connector.
• 12 Vdc is connected to the 2.1 mm concentric power input connector.
PIN Number Access
A PIN number may be programmed to prevent unauthorised access. Whenever line 2 of Mastercall is
called, Mastercall responds with “Hello this is Mastercall, please enter PIN”. If a valid PIN is
received, the telephone line is connected to the isolated radio audio source.
From the Mastercall keypad:
1. Press * # pppp #, where pppp = the required PIN.
• If no PIN is required, press * # 9999 #.
Forced Disconnect
To force Mastercall to release the telephone line, simply press # on the telephone dial pad and hang
up. For automatic disconnection, the telephone line connected to Mastercall must be programmed for
line category ‘Reversal on Idle’ (ROI).
