INSTALLATION | 9
A problem with this arrangement is a result of a hybrid with too much leakage combined
with the system delay. If the hybrid isn’t doing a good job of preventing the send audio from
leaking to its output, the special remote send mix-minus is corrupted. Remember, if any of the
announcer audio from the remote site is returned via the monitor feed, it will be delayed by the
digital link, causing an echo eect. e Telos Hx really shows its stu in this situation. Because
it has such good trans-hybrid loss, leakage is not at all likely to be a problem. And should there
ever be a problem, you can solve it by increasing the amount of ducking. See Section 4.2.
Note
The Telos Hx has the more common pin-outs used for three pin XLR inputs & outputs. You
can easily remember the correct signals when wiring connectors using the phrase “George
Washington Bridge.” Pin 1 = G = Ground, Pin 2 = W = “+” = White (typical color in mic cable, if
there is no white there will be a red conductor), and Pin 3 = B = “-” = Black.
2.3 Hx2 Internal Mix Minus
e two hybrids in the Hx2 unit may be congured so that a single mix-minus feed may be used
for both hybrids, with each hybrid’s output fed into the other’s input internally at unity gain (so
that the callers can hear each other) and sums each with the audio from the consoles mix-minus
output. Only the SEND IN #1 input is used to feed both hybrids.
Both hybrid outputs still function independently. e two hybrid outputs are NOT summed
together, so you should provide a fader for each hybrid. e consoles mix-minus must be
congured so that no hybrid’s output gets sent to its own input.
