Hybrid send & return in consoles Solidyne 2300 series
The 2300 series consoles with master Solidyne 2307 provide connection to send and return hybrid;
through a stereo jack ¼" located on the rear panel. In this way the external hybrid is also managed
from the hybrid's fader, avoiding having to use input channels for connection of the hybrid.
You can ask Solidyne on purchase of hybrid, the cable to connect to 2300 console. Or you can
assemble yourself. The cable will have a stereo plug (TRS 1/4") that connects two shielded cables
(shield and one conductor). One cable connects the tip to a mono plug (TS 1/4") and the other one
connects the ring to a female XLR. The following table shows the connection.
I/O connection to an external hybrid in Solidyne 2300 consoles. Stereo plug brings two cables (Y-cable) (shield and conductor; Belden type).
For Solidyne consoles of other models, and for consoles of others marks, check the
user's manual for send and return conections to external hybrid.
If the console do not have conection Si la consola no tiene conexión para envío/retorno
de híbrido externo, el HL-202 deberá conectarse a un canal de línea, como se explica
más adelante.
In the console 2300, external hybrid signal is sent to the hybrid control at Master module. See the
manual for the operation console with external hybrid.
Remember that the three-line hybrid built on consoles Solidyne 2300, is kept working when you
connect an external hybrid, able to work in conference with internal and external lines (console with
serial # ending in "C").
2.4.3 Recording output
The recording output mix the incoming signal from telephone line and the hybrid's local audio ('Send
to phone line' input). This enables the recording of conference including the Studios. The output level
is fixed (0 dBu / 10Kohms).
2.4.4 Connection to consoles that have no external hybrid I/O (studio and live show
consoles)
In consoles that have no connection to send and return for external hybrid, the hybrid will connect to
a line channel. The output of HL202/203-VQ (Output to console) is balanced XLR. This output must
be connected to a balanced line input on the console to send calls to air (PGM)
To connect this output to an unbalanced input, leave pin 3 unconnected (connect only 1=GND;
2=signal).
Send to phone-line is the audio input of the hybrid, which receives audio from console and sends it to
the phone line. This input is connected to a secondary output of the console, unlike the program output
(Aux, Rec, FX, etc). Logically, the channel through which the hybrid signal enters, do not be assigned to
the mix that is sent to the hybrid (Aux, Rec, FX, etc) because it will cause a feedback loop.

Never use the program out to send audio to the hybrid, because will cause a feedback
