Introduction
With the variety of telephone systems in the world today, from cellular to
digital to analog, it is becoming increasingly difficult to have all callers
sound the same on-air. To help bring uniformity and high quality sound
to a broadcast talk show environment, we have created the Digital
Hybrid 30 (DH30). The DH30 provides a high quality telephone interface between a telephone line and audio equipment. This telephone
interconnection system uses digital hybrid technology, invented by
Gentner, to continually adapt to telephone-line conditions—providing
consistent high-quality sound. Its auto mix-minus generation and
acoustic echo cancellation allow the DH30 to be used in any studio
environment.

OVERVIEW • ABOUT THE DH30
2
Overview
About the DH30
The DH30 continually adapts to telephone-line conditions, providing the
best, most-reliable null possible. This ability, along with its programmable auto-answer, auto-disconnect, and caller control functions, makes
the DH30 a truly smart digital hybrid. The DH30 has selectable auto mixminus and acoustic echo cancellation, allowing it to operate in a variety
of closed or open studio environments. It also has call monitoring capability with a built-in 2-watt monitoring amplifier and front-panel volume
control. AES/EBU connections let you establish a direct digital audio
link between the DH30 and a digital console. Analog connections are
made using the send and cue inputs and the caller and aux outputs.
Each input and output has its own adjustable gain control, ensuring the
best audio mix in every application.
Audio Processing
The DH30’s 24-bit digital signal processing (DSP) produces high-quality
audio with expansion, compression, equalization, and bass boost capabilities. The downward expander, compressor, and 3-band EQ allow you
to fine tune the sound of the caller audio, making the DH30 the best
sounding telephone hybrid on the market.
Telephone Echo Cancellation
Gentner-developed DSP technology provides a high quality telephone
interface between a standard analog telephone line and user audio
equipment. The primary function of the hybrid is to separate send and
caller audio (null). The hybrid provides >55 dB send/caller isolation
between 250 Hz to 3.5 kHz.
User-Adjustable Controls
The DH30 is easily customized. The Enter, Esc, ▲/▼ buttons, along with
the LCD display, provide useful control options, including:
• Selectable answer and disconnect options
• Integrated monitor amplifier with push-button volume control
• Adjustable caller audio control
• Adjustable three-band equalization
• Password protection
• Adjustable compressor/limiter and expander

OVERVIEW • OPERATIONAL REQUIREMENTS
Presets
Presets are the programmable operating parameters that control how
the DH30 responds to the telephone line. The DH30 can store up to
three presets. The unit ships with Preset 1 containing a set of default
values. You can keep these settings or modify them, and you can also
set up two additional presets. The Presets feature allows you to easily
change to a completely different operating profile. If power is lost, the
DH30 powers up with the last preset used, custom presets are not lost.
Operational
Requirements
The DH30 is designed to work in almost any acoustic environment.
However, to improve audio quality and ease of installation, we recommend that you take the following factors into consideration:
Acoustic Room Treatment
Rooms that have large areas of windows, white boards, hard floors, etc.,
are acoustically live. These areas increase the amount of audio reverberation in the room which, in turn, reduces audio quality. To achieve
the best results using the DH30, you should minimize the amount of
audio reverberation wherever possible. You can improve room
acoustics by installing acoustic panels, drapes, and other wall fabrics.
Another way to improve overall room acoustics is to keep room noise
(i.e. computers and fans) to a minimum.
Environmental Requirements
The room temperature at which the DH30 can operate ranges from
32–100 degrees F / 0–38 degrees C, with relative humidity of
0–80 percent.
Telephone Line Requirements
The DH30 operates on standard telephone lines and connects to a
standard RJ11C modular jack. If you do not have an RJ11C jack where
you want to install the DH30, call your telephone company for installation.
Equipment Placement
The DH30 is designed for installation in a standard 19-inch equipment
rack.
Power Requirements
The DH30 automatically adjusts to voltages between 100–240 Vac,
50–60 Hz. Manual voltage switching is not required.

CONNECTING THE EQUIPMENT • CONSOLE CONNECTIONS
Console
Connections
The DH30 ties into console functions through these connectors:
Analog Audio
Send In
This is the audio that the caller will hear. Connect a mic or line output
from the studio console to the Send In input of the DH30.
If the DH30’s echo canceller feature is disabled, you must send mixminus audio to the Send In connector. If you are using a microphone
connected directly to the DH30 that requires phantom power, you will
need to activate the phantom power circuit. Refer to Appendix J.
Cue In
This is the audio the caller will hear when the cue feature, located on
the front panel, is activated. Connect a mic or line output from the studio console to the Cue In input of the DH30.
No auto mix-minus or acoustic echo cancellation is performed on the
Cue audio and therefore the audio sent to this input must be a mixminus.
Caller Out
This is the output of the callers voice. Connect the Caller Out to an input
channel of the studio console.
Aux Out
This is the output of the caller audio and the send or cue audio
(whichever is selected via the Cue button). Connect the Aux Out to an
input channel of your studio console or recording device.
The caller/send mix is programmable through the front panel LCD display.

Auto Mix-Minus and
Acoustic Echo
Electronic echo is the echo caused by the caller’s audio being sent
back to the caller through the mixing console. This can be prevented by
creating a mix-minus at the mixing console. Mix-minus is the mix of
everything you want the caller to hear minus the caller’s own audio.
Acoustic echo is the echo in a room environment. In an application
such as a talk show, speaker audio may be picked up by microphones
and fed back to the caller. Acoustic echo cancellation prevents this
audio from being fed back to the caller.
Mix-Minus/Acoustic Echo Cancellation
Mix-minus and acoustic echo cancellation (AEC) are turned on and off
through the Echo Canceller menu in the LCD panel. Although the DSP
automatically adjusts to cancel echo, it is recommended you train the
echo canceller to the echo when you first install the DH30. (See EC
Train, page 22)

acoustic echo.
Training the DH30
Select Echo Canceller/EC Train in the LCD display. The display shows
both the Echo Return Loss (ERL) and the current Echo Cancellation
(EC).
1. Place a call and route it through the DH30, or have someone
call in. If echo is present, continue with steps 2–7.
2. Select EC Train from the Echo Canceller menu and press
Enter. This sends a constant burst of white noise out of the
Caller Out output. The EC Train uses this white noise to monitor
how much noise comes back to the DH30 through the acoustic
and electronic environment.
3. View the ERL reading on the DH30 LCD display. The ERL
should be at a reading of 0 or below.
4. If the reading is in the positive, decrease the speaker monitor
level and/or the caller audio level of the program mix until the
ERL reading is 0 or lower.
5. Press Esc. This stops the white noise.
6. Have the person on the other end of the telephone line tell you
if an echo is present.

Setting Caller Processing
The Caller Processing menu category in the LCD panel includes six
submenu items for controlling various facets of the caller audio.
EQ (Equalizer)
The equalizer function is used to modify the tonal quality of the caller
audio. The basic function is a simple three-band graphic equalizer. The
adjustments to each band determine how much adjustment is made to
the caller audio signal.
When active, the graphic caller equalizer will have the following characteristics:
• LowBand = 250 Hz – 715 Hz
• MidBand = 715 Hz – 1,645 Hz
• HiBand = 1,645 Hz – 3,500 Hz
Adjustment in each band is from -12 to +12 dB.

SETUP AND OPERATION • CUSTOMIZING THE SOUND OF YOUR SYSTEM
25
Compressor
The function of the compressor is to keep the caller output at the same
level regardless of the incoming level. The caller level should be set to
accommodate the quiet callers. The DH30 compresses, or attenuates,
the louder levels.
The compressor works in conjunction with its threshold setting. The
threshold setting is the level at which compression will begin. The ratio
determines the attenuation applied to levels above threshold. For example, a 2:1 ratio means that for every 2 dB the caller is above threshold,
the audio level will increase only 1 dB. The larger the ratio, the more
compression is applied. The limiter setting keeps the level from exceeding the threshold. The bypass setting disables the compressor.
Ratio options are: Bypass, 2:1, 3:1, 4:1, 6:1, and Limiter.
Threshold is referenced to the level of the caller audio on the
VU meter. Adjustable from –20 dBu to 20 dBu.
Post gain adds gain to all audio to compensate for compression.
Adjustable from 0 to 20 dB.
Attack sets the time required to compress when audio exceeds
threshold. Adjustable from <1 to 50 ms.
Release sets the time required to release compression when
audio falls below threshold. Adjustable from 100 ms to 2000 ms
(2 seconds).
Expander (Downward expander)
The expander reduces telephone line noise when the caller is not talking by decreasing audio gain when caller audio falls below the threshold level. As long as the caller audio remains above the threshold, the
expander function remains at unity gain (no expansion). When the
caller audio sample drops below the expander threshold, the expander
function decreases the gain by the ratio determined at setup.
The expander has the following characteristics:
Expansion ratio is adjustable in the following ratios: Bypass, 2:1,
3:1, 4:1, or 6:1.
Threshold is referenced to the caller out level.
Adjustable from –50 dBu to 0 dBu.
Expansion attack time adjustable from <1 to 50 ms.
Expansion release time adjustable from 100 ms to 2000 ms
(2 seconds).
TECHNICAL SUPPORT: 1.800.283.5936 (USA) OR 1.801.975.7200
If the expander threshold is
set too high, the DH30 may
treat the caller as noise.
This results in downward expansion
of caller audio.
!
26
SETUP AND OPERATION • CUSTOMIZING THE SOUND OF YOUR SYSTEM
If you have increased the
bass in the Caller
Processing menu, you may
need to add echo reduction to
compensate.
✍
Bass Boost
Boosting the bass gives a fuller sound to the caller’s audio by enhancing frequencies below 250 Hz. The front panel LCD program allows you
to adjust the Bass Boost feature over a range of 0 to 10, with 10 being
most enhanced.
Caller Control
Caller control allows the talent to talk over the caller, reducing caller
audio whenever send audio is present. When send audio is present, the
caller will attenuate/duck by the amount adjusted. You can adjust the
amount of caller attenuation provided, from 0 to -30 dB. A typical setting
would be –6 to –12 dB.
Noise Burst
If activated, a momentary noise burst will be sent to the telephone line
when turning the hybrid on. The noise burst allows the DSP to adapt the
telephone echo canceller and provides a better null at the beginning of
the call. Without the noise burst, the DSP may add attenuation on the
caller audio until the DSP has adapted to an acceptable null.
The tradeoff in setting noise burst on is that the caller hears a momentary noise burst, but the telephone audio is immediately adapted.
Setting the noise burst off spares the caller the brief noise, but the
DH30 may require 5 to 20 seconds to adapt.
Training the Telephone Echo Canceller
To retrain a connection to a telephone line, momentarily press
the On button after the hybrid is already connected to the
telephone line. This initiates the same noise burst mentioned
above and retrains the hybrid.
System Parameters
These parameters control the telephone connect and disconnect
modes, remote control switching mode, quality of audio sent to the Aux
Out jack, sample rate for equipment synchronization, passcode protection, notice of the firmware version level, and the panel locking feature.

microphone.
TEC. Telephone Echo Cancellation. The process of removing echo
before it returns to its source over a telephone line.
TERL. Telephone Echo Return Loss. The amount of echo returned to
the audio source over a telephone line.
Telephone Hybrid. A device that converts a telephone line (2-wire,
low-level signal) into a balanced, 4-wire, line-level signal with independent send and receive ports. A telephone hybrid provides the necessary
electronic matching between the telephone line and the audio
equipment. Generally referred to in this manual as simply “hybrid.”
Telephone Line. The line delivered by the telephone company to an
individual subscriber. Sometimes known as a POTS (Plain Old
Telephone Service) line, this is an analog line required by fax machines
and modems. The DH30 requires analog telephone lines for its phone
line connection. PBX systems or other digital telephone systems must
be equipped with an analog extension for use with the DH30.
Threshold. A predetermined point for the start of operation of a circuit.
Unbalanced Audio. A circuit that is referenced to ground.
Wet Line. A telephone circuit over which voice signals are transmitted
and which contains DC offset voltage.

APPENDICES • APPENDIX C: SERIAL COMMUNICATIONS PROTOCOL
The RS232 port on the DH30 is a serial communications port used to
control DH30 operations through an external device such as a PC or a
control device. This appendix describes the protocol and serial commands used to control the DH30.
Appendix C:
Serial
Communications
Protocol
The RS232 serial port runs at 9600 baud, no parity, eight data bits, and
one stop bit.
Serial commands to the DH30 can control the following types of operations: Hybrid On/Off, Cuing, Recording, Monitor volume, Preset
selection and Detection of an Incoming Call.

APPENDICES • APPENDIX C: SERIAL COMMUNICATIONS PROTOCOL
The structure of serial commands is an option/value, followed by a
carriage return:
command x
Commands can be either UPPER CASE or lower case terminated by a
carriage return. Characters are not echoed back to the sending device
as they are sent. After a command has been sent, including the carriage
return, the command is echoed back in uppercase with the new value
followed by a DH30> command prompt.
For example, a command to turn Cue on would be formatted like this:
CUE 1<cr>
(CUE =function command, 1=On, as shown in the facing table.)
The returned response would be:
CUE 1
DH30>
If the Cue feature was off and the toggle Cue command was sent:
CUE 2<cr>
The returned response would be:
CUE 1
DH30>
Indicating that the Cue feature had been turned on.
To get status back on what the current setting is, send the command
without a parameter. For example if the Cue function is on when the
command is sent:
CUE<cr>
The response would be:
CUE 1
DH30>

Appendix H:
Compliance
FCC Part 15 Compliance
This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the
interference at his/her own expense.
Changes or modifications not expressly approved by Gentner
Communications Corporation could void the user’s authority to operate
the equipment.
FCC Part 68 Compliance
A label containing the FCC registration number and Ringer Equivalence
Number (REN) for this equipment is prominently posted on the top
plate near the rear of the equipment. If requested, this information must
be provided to your telephone company.
USOC Jacks: This device uses RJ11C and RJ21X terminal jacks.
The REN is used to determine the quantity of devices which may be
connected to the telephone line. Excessive RENs on the telephone line
may result in the devices not ringing in response to an incoming call. In
most, but not all areas, the sum of the RENs should not exceed five (5).
To be certain of the number of devices that may be connected to the
line, as determined by the total RENs, contact the telephone company
to obtain the maximum RENs for the calling area.
If this equipment causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of
service may be required. If advance notice is not practical, the telephone company will notify the customer as soon as possible. Also, you
will be advised of your right to file a complaint with the FCC if you
believe it is necessary.
The telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect the operation of the equipment. If this happens, the telephone company will provide advance
notice for you to make the necessary modifications in order to maintain
uninterrupted service.

IC Compliance
NOTICE: The Industry of Canada label identifies certified equipment.
This certification means that the equipment meets certain telecommunications network protective operational and safety requirements. The
Department does not guarantee the equipment will operate to the
user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications
company. The equipment must also be installed using an acceptable
method of connection. In some cases, the company’s inside wiring
associated with a single line individual service may be extended by
means of a certified connector assembly (telephone extension cord).
The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by Gentner
Communications. Any repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure, for their own protection, that the electrical ground
connections of the power utility, telephone lines, and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Safety Information
CAUTION: Users should not attempt to make such connections
themselves, but should contact the appropriate electrical inspection
authority, or electrician, as appropriate.
