Radio Systems DI-1000/DI-2000 Single and Dual Line Digital Phone Hybrid Manual
Page Product Description
The DI-1000/DI-2000 is a digital adaptive hybrid designed to interface between the telephone line and
professional audio equipment. The DI-1000 is a single line unit while the DI-2000 is a two-line device.
Both products occupy a single unit of rack space. While the DI-2000 allows conference calls (DIP switches
selectable) both units feature ring detect, auto answer, automatic line release, separate modes of operation
and audio inputs/outputs for cue - hold - air, producer phone control, a speaker amplifier, and full remote
control. Additionally, an Intelligent Console Control interface is provided.
Radio Systems DI-1000/DI-2000 Single and Dual Line Digital Phone Hybrid Manual
Page Installation
All audio wiring is made to 3 conductor 1/4” phone plugs. Wiring a DI-2000 (dual unit) is identical to a DI-1000
unit (single unit) with the exception of the Main and Cue Outputs. It is possible, with a dual hybrid, to provide a
Main Output that is a mix of line 1 and line 2. The same is true for the Cue Output. See DIP switch programming.
Inputs
Inputs are normally wired balanced. Tip is “+”, Ring is “-” and Sleeve is ground. When wiring an unbalanced
piece of equipment to the input of the hybrid, connect the Ring and the Sleeve together.
Cue Inputs
Connect audio to be sent to the caller when the hybrid is in the Answer/Cue Mode (front panel answer/cue switch is illuminated). This would normally be an uninterrupted DJ microphone. This will
allow the hybrid to handle off air conversations with the caller.
Hold Inputs
Connect audio to be sent to the caller when the hybrid is in the Hold Mode (front panel hold switch is
illuminated). This would normally be the air monitor signal. This will allow the caller to listen to the
program while keeping their radio turned down.
Mix-Minus Input
Connect audio to be sent to the caller when the hybrid is in the Air Mode (front panel air switch is illuminated). This would be a mix of all signals (going to air) minus (except) the caller.
Outputs
Outputs are normally wired balanced. Tip is “+”, Ring is “-” and Sleeve is ground. When wiring the hybrid outputs
to an unbalanced piece of equipment make connections to the Tip and Sleeve only. Leave the Ring unconnected.
Cue Output
Provides caller audio when the hybrid is in the Answer/Cue Mode (front panel answer/cue switch is
illuminated). Connect to the console’s external cue input. This will allow the hybrid to handle off air
conversations with the caller. The DI2000 (dual unit) can provide a mix of line 1 and line 2 Cue Output if desired. In this instance, wire only between the Line 2 Hybrid and the console. Set DIP Switch
4 to the on position. See DIP Switch Programming.
Main Air Output
Provides caller audio when the hybrid is in the Air Mode (front panel air switch is illuminated). Connect to the console’s caller input channel. The DI-2000 (dual unit) can provide a mix of line 1 and line
2 Main Air Output if desired. In this instance, wire only between the Line 2 Hybrid and the console.
Set DIP Switch 3 to the on position. See DIP Switch Programming.
Cue Speaker Output
Identical to Cue Output except that a speaker amplifier and level control is provided. Connect a 32ohm speaker between Tip and Ring. Do not make a connection to Sleeve or ground.
Record Output
Provides a mix of caller output and either the Cue Input (if Answer/Cue Mode is selected) or the Mix
Minus Input (if AIR mode is selected) for recording purposes.

Remote Control Wiring
A 25 pin “D” connector provides remote control. Dual hybrids have a separate connector for each line. Unless
noted, all switches are momentary pull to ground. To activate make a momentary connection between the desired
pin and either ground pin. All indicators are open collector current sinking outputs and will drive a maximum of
100mA at 25 volts. Connect indicators from either +5 volt pin to the desired indicator pin. A series current limiting
resistor is recommended.

Page Operation
Manually answering a call (line ringing - Answer/Cue Indicator flashing with breaks - ring
cadence)
Pressing the Answer/Cue or the Hold or the Air switch will answer a call and place the hybrid into the
desired mode.
Automatically answering a call (line ringing)
The hybrid can automatically answer an incoming call and enter the desired mode of operation if it
was previously placed in any of the Auto Answer Modes. To do so, depress the Drop Switch and then
momentarily press the Answer/Cue, Hold or Air Switch. Then release the Drop Switch. The associated indicator will flash slowly. When the line rings the hybrid will answer the call with the desired
mode. When the caller hangs up the hybrid will automatically go “on hook” and resume the Auto
Answer Mode. Momentarily pressing the Drop Switch will cancel the Auto Answer Mode.
Answer/Cue Mode
This mode can be entered at any time by pressing the Answer/Cue Switch. The Answer/Cue LED
will illuminate. It will take the hybrid “off hook” and answer a call. The incoming caller’s audio will
be routed to the Cue and Cue Speaker Output. The caller will hear the audio connected to the Cue
Input. The producer’s phone is disabled.
Hold Mode
This mode can be entered at any time by pressing the Hold Switch. The Hold LED will illuminate. It
will take the hybrid “off hook” and answer a call. The incoming caller’s audio is muted. The caller will
hear the audio connected to the Hold Input. The producer’s phone is enabled.
Air Mode
This mode can be entered at any time by pressing the Air Switch. The Air LED will illuminate. It will
take the hybrid “off hook” and answer a call. The incoming caller’s audio will be routed to the Main
Output. The caller will hear the audio connected to the Mix Minus Input. The producer’s phone is
disabled.
Drop Mode – hybrid “on hook”
This mode, which will terminate the call, can be entered at any time by pressing the Drop Switch. All
LEDs will extinguish. The producer’s phone is enabled.
Automatic Release
The hybrid automatically monitors line loop current. If the caller hangs up the hybrid will detect the
change in the loop current and go “on hook”.
Producer’s Phone
A producer’s phone (desk set) may be connected (optionally) to the hybrid. The hybrid restricts usage
of the phone to when the hybrid is “on hook” or in the Hold Mode. When the producer is speaking to the
caller the Answer/Cue Indicator will continuously blink and pause. If the producer’s phone is taken “off
hook” when the hybrid is in the Hold Mode, the hybrid will exit the Hold Mode and release the line. The
producer should press the hybrid’s Hold Switch to put the caller back on hold.
Conference
The DI-2000 (dual hybrid) allows conferencing between two phone lines if desired. There are two
modes of possible conferencing – each has a separate DIP switch that must be set.
Radio Systems DI-1000/DI-2000 Single and Dual Line Digital Phone Hybrid Manual
Page Answer/Cue conference – allows callers on both lines to talk to each other when in Answer/Cue
Mode with DIP switch #2 has been closed (down position).
Air Conference – allows callers on both lines to talk to each other when in Air Mode when DIP switch
#1 has been closed (down position).
A conference inhibit switch is available through the remote control. As long as the switch is closed all
DIP switch-programmed conferencing will be inhibited.
Combined Audio Output (Conference Mode)
When in conference mode (cue and/or air), it may be useful to have the cue and/or air outputs
combined into one audio feed. To accomplish this, set DIP switch #3 on (down) to combine the air
feeds into air feed output #2 (air output #1 is not used). Set DIP switch # 4 on (down) to combine
cue feeds into cue output #2 (cue output #1 is not used). Note - Combined audio outputs do not function independently of the conference modes (i.e. DIP switch #1 must be on for switch #3 to work; DIP
switch #2 must be on for switch #4 to work
Audio Mix Minus Input (Conference Mode)
Mix Minus inputs are not combined in the conference mode. That is, it is still necessary to wire separate mix minus audio inputs for both callers 1 & 2. Typically mix minus #1 would be minus caller #1,
and mix minus #2 would be minus caller #2.
Intelligent Console Control
If desired the console channel assigned to the incoming caller can control and show hybrid status.
Wiring must be made between the hybrid remote control and the console channel remote control.
Note that the console used must provide access to the off button (ready) lamp, as well as provide
multiple remote momentary closures when the channel “off” or “on” button is pushed.
Console Ready (channel off) Lamp
Off when hybrid is in the Drop Mode “on hook”.
Illuminates to indicate that the hybrid is in the Answer/Cue Mode.
