Page 3: Aes-S3 (Aes Splitter):
Aes-s3 (aes splitter): why use an aes/ebu splitter: because of the high frequency content of an aes/ebu digital signal, the connection between a transmitter and receiver needs to be that of a transmission line. This means the cable must have a characteristic impedance equal to the output impedance o...

Aes-s3 connections input one aes/ebu xlr female outputs three aes/ebu xlr male specifications one transformer balanced input on xlr female input impedance = 110 ohms three transformer balanced outputs on xlr male output impedance = 110 ohms sample rate : up to 96khz jitter : 2.

Aes-d2 (aes/ebu channel divider): why use an aes/ebu channel divider: the aes/ebu digital signal contains two audio channels (left & right, also called a & b or 1 & 2) on the same transmission line. In some applications you may need a mono signal. The aes-d2 enables you to extract a mono signal from...

Aes-d2 connections input one aes/ebu xlr female outputs two aes/ebu xlr male specifications one transformer balanced aes/ebu input on xlr-f. Input impedance: 110 ohms two buffered transformer balanced aes/ebu outputs on xlr-m. Output impedance: 110 ohms channel selection on each output: aa, ab, bb, ...
Page 7: Using The Aes-Spd:
Aes-spd (aes/ebu s/pdif converter): why use an aes/ebu s/pdif converter: often, it is necessary to connect a professional device (aes/ebu) with some semi-pro or home studio equipment (s/pdif) or vice versa. The aes-spd solves this problem. Also all outputs are available simultaneously. Using the aes...

Spd-s4 (s/pdif splitter): why use an s/pdif splitter: because of the high frequency content of an s/pdif digital signal, the connection between a transmitter and receiver needs to be that of a transmission line. This means the cable must have a characteristic impedance equal to the output impedance ...

Clk-d4 (clock distributor): why use a clock distributor: because of the high frequency content of a word clock signal (even higher with super clock), the connection between a transmitter and receiver needs to be that of a transmission line. This means the cable must have a characteristic impedance e...

Connections inputs one clock input bnc four clock outputs bnc specifications: input on bnc. Input impedance : 75 ohms or open buffered output on bnc. Output impedance : 75 ohms jitter: 10
Page 13: Clk-C4 (Clock Converter):
Clk-c4 (clock converter): why use a clock converter: when working in a studio or on a project where both word-clock and super-clock equipment is being used it will be necessary to synchronise the two standards. The clk-c4 solves this problem by its ability to automatically detect and lock onto which...

Connections inputs one clock input bnc four clock outputs bnc specifications: input impedance : 75 ohms or un-terminated output impedance : 75 ohms led indication of word-clock or super-clock input led indication of word-clock to super-clock lock jitter: 12.
Page 15: Why Use A Clock Generator:
Clk-g4 (clock generator) : why use a clock generator: a clock generator is used to synchronise equipment in a digital audio environment. Most master clock generators on the market also synchronise with video for post production, this can make a master clock very expensive. For applications which do ...
