Introducing the innkeeper 2/4™

Innkeeper 2 and innkeeper 4 will allow you to send and receive audio over
analog telephone lines. While this may seem like a simple task that any
telephone can do, the challenge is getting the best quality audio from such a
miserable audio path.

What is a Digital Hybrid?

The innkeeper 2/4 digital hybrids connect audio signals to a standard analog
telephone line without the variations in quality found with analog hybrids. The

main function of a hybrid is to bring in the caller’s voice from the phone line as

clear and clean as possible. In the real world, when you send your voice down

the telephone line it has a tendency to bleed over into the caller’s audio. The

hybrid must adapt to the phone line in order to properly separate transmit and
receive audio. We use a 16 bit DSP (Digital Signal Processor) to continuously

monitor the phone line and local audio signals to deliver excellent trans-hybrid

loss, also known as separation. Our dual-convergence algorithm can achieve

excellent separation, typically exceeding 50 dB.

Ready to go?

The innkeeper 2/4 controls and connectors are clearly marked and ready for

operation. If this is your rst exposure to a hybrid, we suggest that you read the

entire manual to allow you to take advantage of all these features.

Any Questions?

Before you pick up the phone... Please thumb through the rest of this manual.

You might nd those deep technical questions are covered on later pages.

Transmit Signals

The goal is to drive the phone line at high enough levels to avoid phone line

noise, but not so loud as to cause excessive clipping. Adjust your <Send> audio
signals to a level slightly less than the point where you see occasional ashes of
red on the Transmit LED. These ashes should occur during loud speech bursts
only. If the Transmit LED stays lit red for extended periods, you can assume

that much of your speech is being clipped or distorted. In this case you should
lower the audio levels for the signal that is causing the clipping. The innkeeper
2/4 menu will also allow you to adjust your input levels in 1 dB increments over a
+/-10 dB range.

Receive Signals

The innkeeper 2/4 menu will allow you to adjust individual Caller output levels in
1 dB increments over a +/-10 dB range to give you the best signal level at your
equipment. The Caller level control in the menu will not change what you see on
the Receive LED.

Auto-Answer

The Auto-Answer feature can be activated through the innkeeper 2/4 menu. You
may select which phone lines will have auto-answer enabled as well as how
many rings before autoanswer. When Auto-Answer is enabled, you can still take

calls manually using the call button. When nished, you can either drop the call

manually or allow the call to auto-disconnect. Innkeeper 2/4 will look for a CPC
disconnect signal or ROH message from the phone company to determine when
a call has disconnected. This can take up to a minute.

Remote Terminal Block

Remote Jack

The 10 pin RJ-50 jack on the back of the innkeeper 2/4 provides a proprietary
connection to the supplied remote terminal block. A 1-meter cable is provided for
this connection. This jack can also be used to connect to the optional JK Audio
RIU-IP remote interface unit (page 12).

Remote Terminal Block

The Remote Terminal Block includes an Off-Hook signal pin and a Call/Drop
control pin for each phone line channel. The OH signal pin is current limited to 50
mA, 5 VDC. The control pin toggles the corresponding phone line off-hook/on­hook with a connection/break from ground.

This terminal block was designed to allow remote off-hook/on-hook control and
status for each phone line. The innkeeper 2 model also provides on/off control
and status for the Conference feature. Use only the included RJ-50 cable to
connect the Remote Terminal Block to the <Remote> jack on the innkeeper 2/4.

Connecting the Line OH Control pin to the Ground pin will take the line off-hook,
breaking this contact will release the line and disconnect the call.

The OH Status pin will provide 5V, 50mA current when the corresponding line is
off-hook. You can use this pin to drive a relay, light an LED, etc.

Setting Up

Although each application will require a slightly different setup, following is a

general cable conneciton setup and explanation.

1. Connect the supplied RJ-11 phone line cable(s) between the jack marked

<Line> and your wall jack(s). Be sure these jacks supports standard single

line analog telephone operation. The innkeeper 2/4 will not work with "dry
pair" phone line connections

2. Connect to your mixer using the Mix-Minus method. See Figure 7a.

A mix-minus signal is an audio signal that contains a mix of your local

microphones plus any other audio, minus the Caller’s own voice. Sending
the Caller’s audio back to the innkeeper 2/4 will cause an echo, or feedback.

1. Connect a line-level audio signal to the innkeeper 2/4 <Send> jack(s):

a. <Send> jack(s): Audio will only be sent down the

corresponding line.

b. <Master Send> jack: Audio will be sent down either or both phone

lines based upon your selections in the menu. Each caller output
jack will contain audio only from its corresponding phone line.

2. Connect the <Caller> jack to a line-level input(s) on your

mixing console. Local audio and audio from alternate phone lines will

not be present on these jacks. Innkeeper 2 has the ability to send

isolated caller audio, mixed caller audio, or mixed caller and local audio

from the Caller XLR depending on selections made in the Conferencing
menu.

For whichever input channel you have the <Caller> connected to on

the mixer, turn the corresponding <Aux> control to minimum. All other
<Aux> controls should be set for audio sent to the phone line. Each
<Aux Send> bus is completely separate from all other outputs, so

these Aux controls will not affect what is heard on the Main outputs or
on any other Aux buses. We recommend using an <Aux Send> bus

that is pre-fader, so you can use the fader controls to set the levels
of each channel to the main output without affecting what is sent to
the phone line. If your mixer does not have an <Aux Send> bus, you
can use <Pan> controls with the Left and Right outputs. Pan all the
microphones, etc. to the Left output and pan the Caller to the Right
output. Then connect only the <Left> output to the innkeeper 2/4

<Send>. Or, you may use an external Mix-Minus box that will create

this signal for you.

3. Connect the supplied AC power cord to the back of the innkeeper and then

to an AC power outlet.

Your innkeeper 2/4 is now ready to take calls. You may want to connect an
auxiliary telephone to the innkeeper <Aux> jack so you can dial out and set up
calls, or use the <Auto-Answer> feature to answer incoming calls.

Conference

One press of the <Conference> button will join the audio paths of both Line 1
and Line 2, provided there are calls present on both lines. A second press of
the <Conference> button will break the audio paths between the calls. An auto­dropped or manually dropped line will automatically break the conference. By
default, Line 1 <Send> and Line 2 <Send> audio will be mixed together digitally
and sent into both phone lines. Line 1 caller will hear Line 2 caller audio. Line 2

caller will also hear Line 1 caller audio. In the menu, this conguration is referred

to as Send-Mix, Caller-No Mix. This default conguration is by far the most
widely used. Advanced options are available for Conference mode; however for
most situations it will not be necessary to change these default options.

Innkeeper 2 Advanced Conference Options

The factory default conference mode provides both callers with a mix of Line 1
<Send> and Line 2 <Send> audio. Additional mix options can be found in the
Conguration menu. These options allow you to enable and disable <Send> and
<Caller> mix features. Keep in mind that no matter what options are selected,

both callers will always be able to communicate with each other in Conference
mode.

Send = Mix (default)

Line 1 <Send> and Line 2 <Send> audio is mixed and sent to both Callers.

Send = No Mix

Line 1 <Send> audio to Caller on Line 1.

Line 2 <Send> audio to Caller on Line 2.

Caller = No Mix (default)

Caller 1's voice/audio will only be on the Line 1 <Caller> output XLR.
Caller 2's voice/audio will only be on the Line 2 <Caller> output XLR.

<Send> audio will not be present on these outputs.

Caller = Caller Mix

Callers 1 and 2 voice will be mixed on both <Caller> XLR outputs.
<Send> audio will not be present on these outputs.

Caller = Full Mix Minus

A full mix of all audio on each of the caller XLR outputs, minus the <Send>

audio for that phone line.
Line 1 <Caller> XLR contains Caller 1 + Caller 2 + <Send> 2.
Line 2 <Caller> XLR contains Caller 1 + Caller 2 + <Send> 1.

FCC and International telecom rules require that we drop the connection if
power is lost for any period of time. We strongly suggest that you use a low
cost, computer style UPS system if uninterrupted service is required.

5. Does the innkeeper2/4 use a line polarity reversal to drop a

call automatically?

No, innkeeper 2/4 does not use line polarity reversal as means of
dropped-call detection.
