1050 Overview

The CA (controllable audio) series of products from Calypso bring high quality, fully

controlled

audio to classrooms, board rooms, training facilities and other small room applications in need of

compact,

easy-

use

integrated audio. The CA-500 and CA-1000 audio amplifiers deliver 32W

of extraordinarily clean power, optimized f

4 ohm and 8 ohm speakers, while providing full IR

and Serial control. The CA-

500

delivers

a single balanced or unbalanced input and stereo

output

, while the CA-1000 offers three stereo and one mono input, with an on-board mixer for

defining presets, digital gain control and automated ducking when microphone input is

detected.

And when more power is needed, the CA-

1050

pre-amp can be used for multi-

channel control over nearly any consumer or professional quality amplifier, still within the same

compac

t format.

CA Series setup is through its on

board serial programming port, using its companion

-Config

software utility, a simple, graphical interface used to configure all variable settings on CA-

500,

-1000 and CA-1050 units. This user manual rev

iew

s all three CA models and CA-

Config

software, which automatically detects which model it s connected to, and presents the

appropriate configuration options for that model. CA-Config is

not

designed to function as an

end

-user interface, but is intended as a configuration utility used only by authorized Calypso

resellers

Program mode vs. Run mode

CA Series products have

two (2) basic modes of operation:

Program M

ode

allows general configuration of the device

plus IR/Serial Tr

igger.

Run

ode

allows IR and SERIAL triggers to be

recognized

and

decoded.

The device MUST BE IN PROGRAM MODE in order for it

communicate with CA

Config

software

If the serial settings on the device remain at their factory settings1, and properly connected via a

serial cable, the device will

automatically

placed in

Program mode by CA-Config software

when

the software is launched. Program mode is indicated by a blinking blue LED on the

surface of the CA device.

If, however, the serial settings on the device have been modified, e.g., to enable remote, serial

control of the amplifier or pre

amp, CA

Config will not be able to initiate communications with the

device nor put it into Program mode. When this happens, the device must be forced int

Program Mode, using the following steps:

Unplug power

Short a 2

terminal block

by connecting a wire that runs between pin

1 and pin

-2

(hint:

a broken paperclip works well)

Insert the shorted

terminal block

into the

pin serial connector

slots on th

e right side of

the device

Power up the device

Immediately remove the shorted jumper

Connect the serial cable attached to the computer running

Config software

he unit will now be in Program mode and the top, blue LED will

blink continually.

mini audio jack.

1.2.6

Channel 4

Audio Input

(CA

1000 and CA

1050 only)

Channel 4 will accept a mono input via a 2

screw

down terminal

block

on the left side

of the unit.

NOTE ON CHANNEL INPUTS

: All channels are stereo (ch1, ch2, ch3)

except

channel4 (mono).

Channel

4 has

a permanent jumper linking its l

eft and right side

. Ch

annels 1 through

annel

have separate left and

right stereo

lines

While monitoring for

microphone input levels

(typically,

but not necessarily on channel 4), the system searches only the LEFT side. Hence single

channel

microphone

s must be connected to the LEFT side input. Alternatively, the channel

used for mi

crophone input should be set to operate in mono mode.

1.2.7

Speakers

(4 ohm and 8 ohm)

Left and right 4 or 8 ohm speakers are wired via a 5

screw

down terminal block

found

on the right side of the unit.

Two pins are used for the left speaker, two are used

for the

right speaker and the middle pin

can be

used as a common ground.

1.2.8

IR In

put

IR signals can be transmitted to the unit in two ways:

(a)

The 3 triangular holes on the right side of the case allow for over

the

air IR

reception, good for line

sight t

ransmission, up to approximately 30 feet.

(b)

IR signals may also be sent to the unit via hardwire, using the middle two pins on the

pin connector located on the right side of the unit

labeled

/GND and IR1+ IN

Note that pin

3 is a shared ground conne

ctor.

1.2.9

Headphones

Using CA

Config Software

Once the unit is wired and powered up, CA Series configuration is managed entirely by CA-

Config software, which is provided on a CD with the unit. CA-Config software must be install

on the PC connected to the CA-1000 unit via the serial programming cable.

After

launch

ing the

software

select the

appropriate

serial port from the pull-

down;

should

automatically

initiate

communications

with the CA unit2. Note that reselecting the serial port from the drop-

down

menu re-initializes the application.

-Config is a single-screen interface that provides all

settings and options with simple

push

buttons and pull

down menus.

Refer to section 1.1 for instructions on manually putting the unit into Program Mode.

1.3.1

Input Channel Settings

The CA-500 CA-Config interface will provide access to Channel 1 In only, whereas all

channels will be active for CA-1000 and CA-1050 products. For each active channel, the

column of push buttons provide the following functions:

Enable / Disable

turns the channel on or off

Stereo / Mono

set the channel to stereo o

r mono input

hannels 1

3 only)

Gain + / Gain

Use this setting to normalize volume across multiple inputs

, with 32 steps.

Ignore PA3

available as an input to channel 4 (mono) only, this feature detects activity

on a PA system

and automatically triggers an automat

ed mute on input channels 1, 2 and

The PA Detect circuit is triggered when the corresponding input on channel 4 exceeds

the defined Threshold setting.

This button rotates between three states:

Ignore PA

do nothing

PA w/norm

upon PA detect, mute

channels 1,2 and 3

and amplify channel 4 input

as per most recent (current) channel 4 settings. Note that current amplifier

settings may include low volume (determined by channel 4 Gain and Master

Volume) and/or mute, either of which would compromise the effectiveness of the

PA announcement.

oPA w/preset

upon PA detect, mute channels 1,2 and 3 and amplify channel 4

input as per a preset channel 4 PA volume. Use the Set PA Volume button to

define the PA preset volume condition, as per

Master Out s

ettings

. Note that when using the PA

w/preset condition, channel 4 mute is automatically

turned off upon detection of a PA input.

In addition,

The

PA Restore

pull down defines the amount of time the amplifier waits between

the end of an active PA sig

nal and un

muting other channels

Mic Off / Mic On

use to define whether a microphone is connected

as the input device

the channel.

Note that t

he system allows for

only a single microphone input

Microphone detect and PA detect are mutually exclusive channel 4 conditions

Page

In multi-channel audio applications, microphones are often treated as a special input

device, capable of triggering automated ducking , where the volume of other inputs

automatically drop to preset levels, allowing microphone audio to be the dominant

source.

Accordingly, when a Mic On button is selected the Level setting for the active

microphone channel is changed to a Threshold setting, which is the microphone gain

threshold at which automated ducking of other channels initiates. Note that the

microphone threshold setting can be set manually, using the Thresh+ and Thresh-

buttons, or automatically, using the Scan Level button for the appropriate (i.e.,

microphone) channel.

Note: While monitoring for microphone input levels (typically, but not necessarily on

channel 4), the system searches only the LEFT side. Hence single channel

microphone

must be connected to the LEFT side input or plugged into a input set to operate in mono

mode.

After defining the ducking threshold level, one must also set the

setback

level of the other

audi

o inputs, using the existing, yellow

Setback

+ and

Setback

buttons.

Finally, the Mic restore pull down defines the amount of time the amplifier waits between

the end of an active microphone signal and resetting the other channels to their normal

volum

e levels.

1.3.2

Master Out

Note: The amp waits 2 seconds after power on until output is enabled.

The settings on the Master Out menu bar determine audio output from the

device.

Channel Pull Down
