AUDIO CONFIGURATION
ESTABLISH A MIX MINUS OUTPUT ON YOUR CONSOLE
1. A mix minus is the mix of all the sources you want the caller to hear, minus the caller. The caller can
already hear themselves on the phone (side-tone), so it is not necessary and undesirable to send the
caller’s audio back to the caller.
2. Based on your model, proceed to the appropriate steps to set up either your Hx1 or Hx2.
HX1 AUDIO CONFIGURATION
a. Connect one cable to the SEND IN XLR jack (E). Connect the other end of the cable to the phone
bus line output of your console.
b. Connect one cable to the RCV OUT XLR jack (F). Connect the other end to the line input for the
channel designated for callers on your console.

Telos recommends connecting your Hx1 / Hx2 to professional-grade audio equipment with balanced audio
connections. If your Hx1 / Hx2 must connect to semi-pro "unbalanced" audio inputs or outputs, we recommend
using a two-way, external balanced / unbalanced line level converter. Common models include the "Matchbox",
"ProMatch", and "CleanBox Pro", as well as other model names.
MAKING YOUR OWN CABLES?
If it is necessary to make your own cables to patch the system into your console,
please refer to the illustration below for proper configuration.

HX2 AUDIO CONFIGURATION
a. Connect one cable to the SEND IN #1 XLR jack (E). Connect the other end of the cable to the
phone bus line output of your console.
b. Connect one cable to the RCV OUT #1 XLR jack (F). Connect the other end to the line input for the
channel designated for callers on your console.
c. Connect one cable to the SEND IN #2 XLR jack (G). Connect the other end of the cable to the
phone bus line output of your console.
d. Connect one cable to the RCV OUT #2 XLR jack (H). Connect the other end to the line input for the
channel designated for callers on your console.
Hx2 TIP: If only one mix minus can be sent from your console, don’t fret! You can set up an
internal mix minus by setting the OPTIONS DIP #6 Switch on the rear panel to the ON position.
When this is done, the signal at SEND IN #1 will be sent to both callers and each callers’ audio will
be sent to the opposite hybrid for conferencing.

DIP SWITCH CONFIGURATION
1. NOTE: If you are using the Hx1 or Hx2 outside of the United States of America, please refer to the "Country
Specific Configuration Settings" Section in the manual for instructions and tables for setting the internal
DIP SWITCHES to the proper Telco Country setting.
2. On the rear panel of the Hx1 and Hx2 hybrid are two banks of DIP switches (I) labeled SETTINGS and
OPTIONS. The SETTINGS bank of DIP switches (SW1 & SW2) allows you to control the operational levels of
various signal processing stages of the hybrid unit.
3. The illustration (I) depicts the factory default setting for the Hx1 and Hx2. Please refer to the product
manual for full descriptions of settings and functions.
4. If no special settings are required, make sure DIP switches are in the default position.

PERFORM AN OPERATIONAL TEST
1. Connect the Hx1 or Hx2 to AC Mains (J).
2. The unit will complete a self test.
3. A dot should be present on the front of the display (K) if the phone line is properly connected. If a minus sign
is displayed, the unit does not detect the line voltage and your wiring should be checked. If you are testing an
Hx2 with two POTS lines connected, make sure a dot is visible on both displays.
4. Press the Hybrid ON button (L). A dial tone should be present on the hybrid’s output and RCV bargraph meter
(M). If you are testing an Hx2 with two POTS lines connected, this step should be performed for each line
independently.
5. Verify correct mix minus operation at this point by noting that the RCV bargraph (M) shows the dial tone at
a nominal level, and that the SND bargraph (N) shows only the microphone or audio present on the device
feeding the Hx SEND IN. You should only see dial tone on the RCV meter. If you see dial tone on both SEND
and RCV meters, check your mix minus.
6. Press the Hybrid OFF button (O) to end the test.

YOUR SETUP IS COMPLETE!
That’s it! You are now ready to experience the Telos Hx1/
Hx2 for optimal caller audio quality.
1. To make an outgoing call, make sure that the hybrid is off (dot on the display (K)). Using the POTS phone
attached to the PHONE jack, seize the line, wait for a dial tone, and dial the desired number. When you are
ready to place the caller on the hybrid, press the ON button (L), wait for the hybrid to take the caller and hang
up the POTS phone.
2. To screen an incoming call, simply answer the call on the POTS phone attached to the PHONE jack on the rear
of the Hx. When you are ready to place the caller on the hybrid, press the ON button (L), wait for the hybrid
to take the call, and hang up the POTS phone.
