GS1U-051 TIME CODE & REFERENCE CLOCK
DISTRIBUTION AMPLIFIER

The Glensound GS1U-051 has been developed especially for use with the BBC ATM project. It is a distribution amplifier for a master reference frequency of 153.6KHz mixed with a standard time code signal. It is essential that the 153.6KHz reference frequency is not modulated with the time code and great care has been given to ensure an excellent performance.
Provision is made for two separate inputs of both reference frequency and time code. Front panel LEDs indicate the presence of signals and, along with front panel multi-turn presets, permit the correct levels to be set.

8   64 individually buffered 200 ohm outputs
8   4 outputs provided on each of 16 RJ45 front panel connectors
8   4 separate inputs provided on rear panel XLR connectors
8   XLR input sockets are paralleled with plugs to simplify interconnection of 2 units
8   Time code inputs are > 10k ohms and accept 0.5 to 5.5 volts pk to pk signals
8   Reference frequency inputs are 600 ohms and accept 1 to 4 volts pk to pk signals
8   Automatic selection of second source if first source fails
8   Reference frequency sources are checked for frequency and amplitude
8   Modulation products within +/- 500Hz of the ref frequency are > 90dB down
8   Output level of reference frequency alone = 2v pk to pk into 200 ohms
8   Output level of time code alone = 1v pk to pk into 200 ohms
