Telos Hx1/Hx2 Digital Hybrid Telephone Interface

Introduction

Thank you for purchasing the Telos Hx1/Hx2 Digital Hybrid Telephone Interface.

This quick-start guide will take you through the basic steps to configure your new Hx1 or Hx2 to start delivering clean, clear caller audio to your show in no time. Before we get started, let's make sure you have what you need.

Items Required for Installation

• Telos Hx1 or Hx2 Digital Hybrid Telephone Interface
• AC Power Cable
• Rack Mount Hardware
• RJ-11 cable for POTS Line
• An available 1RU 19 inch rack mount enclosure slot
• POTS Phone Set
• Regular analog POTS line from the Telco

Initial Setup

Physical Connections

Install your Hx1 / Hx2 in a 1 RU high space on a standard 19" rack.

The rear panel of the Hx1 and Hx2 units feature several connection points:

• RJ-11 LINE (A): For connecting the POTS line.
• RJ-11 PHONE (B): For connecting a POTS phone.
• XLR SEND IN: For sending audio from your console to the hybrid.
• XLR RCV OUT: For receiving audio from the caller to your console.
• DIP Switches: For configuration settings.
• AC Power Input: For connecting the power cable.

For the Hx2, there are additional connections for a second hybrid:

• RJ-11 LINE (C): For the second POTS line.
• RJ-11 PHONE (D): For the second POTS phone.
• XLR SEND IN #2: For sending audio for the second hybrid.
• XLR RCV OUT #2: For receiving audio for the second hybrid.

1. Connect your POTS line to the “LINE” RJ-11 jack (A) with a supplied RJ-11 cable.
2. Connect your POTS Phone to the “PHONE" RJ-11 jack (B) with an RJ-11 cable.
3. For Hx2 users: To establish connections for HYBRID #2, connect your POTS line to the "LINE" RJ-11 jack (C) and connect your POTS Phone to the "PHONE" RJ-11 jack (D) for HYBRID #2 with an RJ-11 cable.

The initial connections for your Hx1 / Hx2 are complete and ready to be configured for audio input. Continue to the "Audio Configuration" instructions.

Audio Configuration

Establishing a Mix-Minus Output on Your Console

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.

Based on your model, proceed to the appropriate steps to set up either your Hx1 or Hx2.

Hx1 Audio Configuration

The Hx1 features one set of audio connections:

• SEND IN (E): Connects to your console's phone bus line output.
• RCV OUT (F): Connects to your console's line input for the channel designated for callers.

1. 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.
2. 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.

Making Your Own Cables?

If it is necessary to make your own cables to patch the system into your console, refer to the illustration for proper configuration. An XLR male connector has pins for Pin 1 (Ground/Shield), Pin 2 (Hot +), and Pin 3 (Cold -). An XLR female connector has corresponding sockets.

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, consider using a two-way, external balanced / unbalanced line level converter. Common models include the "Matchbox", "ProMatch", and "CleanBox Pro".

Hx2 Audio Configuration

The Hx2 features two sets of audio connections:

• SEND IN #1 (E): Connects to your console's phone bus line output for Hybrid #1.
• RCV OUT #1 (F): Connects to your console's line input for the caller channel for Hybrid #1.
• SEND IN #2 (G): Connects to your console's phone bus line output for Hybrid #2.
• RCV OUT #2 (H): Connects to your console's line input for the caller channel for Hybrid #2.

1. 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.
2. 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.
3. 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.
4. 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, 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 caller's audio will be sent to the opposite hybrid for conferencing.

The audio configurations for your Hx1 / Hx2 are complete. Continue to the "DIP Switch Configuration" instructions.

DIP Switch Configuration

Rear Panel DIP Switch Control

The rear panel of the Hx1 and Hx2 hybrid units feature two banks of DIP switches:

• SETTINGS: Allows control over operational levels of various signal processing stages.
• OPTIONS: Provides additional configuration options.

The illustration (I) depicts the factory default settings for the Hx1 and Hx2. Please refer to the product manual for full descriptions of settings and functions.

Important Notes:

• If 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.
• If no special settings are required, ensure DIP switches are in the default position.

The Hx1 / Hx2 is configured and ready to make or receive calls. Continue to the "Test Your Connection" instructions.

Testing Your Connection

Performing an Operational Test

Follow these steps to test your setup:

1. Connect the Hx1 or Hx2 to AC Mains (J). The unit will complete a self-test.
2. Check the front panel display (K). A dot should be present 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. For an Hx2 with two POTS lines connected, ensure a dot is visible on both displays.
3. Press the Hybrid ON button (L). A dial tone should be present on the hybrid's output and the RCV bargraph meter (M). For an Hx2 with two POTS lines, perform this step for each line independently.
4. Verify correct mix minus operation: The RCV bargraph (M) should show the dial tone at a nominal level. The SND bargraph (N) should show only the microphone or audio present on the device feeding the Hx SEND IN. If you see dial tone on both SEND and RCV meters, check your mix minus configuration.
5. Press the Hybrid OFF button (O) to end the test.

Your Setup is Complete! You are now ready to experience the Telos Hx1/Hx2 for optimal caller audio quality.

Using the Attached Phone

To make an outgoing call:

1. Ensure the hybrid is off (no dot on the display (K)).
2. Using the POTS phone attached to the PHONE jack, seize the line, wait for a dial tone, and dial the desired number.
3. When 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.

To screen an incoming call:

1. Answer the call on the POTS phone attached to the PHONE jack on the rear of the Hx.
2. When 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.
