About Discs

Only handle discs by the edge. Do not touch the silver disc surface. If a disc requires cleaning, wipe it with a soft cleaning

cloth moving from the centre outwards. Do not wipe the disc in a circular motion. When not using discs, store them in a case.

Never place the disc on a surface out of it’s case as the disc will be permanently damaged. A disc damaged by marks and

scratches may no longer play. Even if it does play, the audio quality may be degraded.

Red Book Standard

Stream III is a ‘Red Book' standard CD player and as such will play any genuine red-book disc. These discs will normally carry

the Compact Disc logo. Some discs have been manufactured using various forms of copy protection such as Cactus and

the Sony BMG system. These discs, which do not normally carry the registered logo, may produce erratic behaviour when

played in Stream III and have been the subject of much controversy. More information on this subject and listings of corrupt

titles are available on various websites. Even if a copy protected disc does play, the audio quality may be compromised. Try

to avoid purchasing this type of disc wherever possible.

Discs That Cannot Be Played: Stream III is designed to play audio CDs only. CD-R discs optimised for audio use and

some ‘silver’ CD-R discs may also play correctly. Non-silver CD-R discs will not play. The player will play all discs fully

conforming to the Philips red book standard but may not play discs with some types of copy protection.

Introduction STREAM III

Overview

STREAM III

Overview

Stream III is much more than a CD player. It is also a high-performance 24bit/192kHz DAC with multiple inputs and USB

CODEC. Also, by the use of our LIPS interface technology, Stream III may control aspects of the complete audio system. For

example, if a source other than CD is in use, simply selecting play will automatically switch the amplifier to the CD input and

select a default low volume level. Stream III may also be fully controlled by LIPS, enabling wired integration with control

systems such as Procontrol™or Crestron™.

LIPS - Leema Intelligent Protocol System

LIPS is a proprietary communication system which enables Leema audio components to talk to each other. A degree of

intelligence is instilled in each unit allowing the units to make decisions based on user requirements and system

configuration. For example, in a multi-channel system, the components understand which of them are required for normal

stereo material and which are required for multi-channel playback. When the user switches between input formats, the units

respond by powering up or down as required. In this way, the system is made much easier to use and energy is not wasted

powering units that are not required. Stream continues this theme and is able to control other units in the family, allowing the

majority of the system to be hidden away if required, in an air conditioned cupboard for example.

Making a LIPS connection

LIPS cables are directional and have one black end and one red. If Stream III is controlling other units, the black connector

should be plugged in to either LIPS socket on Stream and the red connector plugged in to the first amplifier component, e.g.

Pulse III. If Stream III is to be controlled, the black connector is connected to the master device and the red connector is

plugged in to either LIPS socket on Stream III.

Front & Rear Panels STREAM III

Power Inlet

Ensure that the voltage

indicated is correct for your

area. This will normally

either be 230VAC or

115VAC.

‘LIPS’ bus connectors

These allow communication

between various Leema

system components.

RCA Audio Outputs

Use phono leads to connect

these outputs to conventional

unbalanced amplifier

Inputs.

Rear Panel

DIGITAL Output

Use a dedicated digital phono

lead to connect this output to

an SPDIF digital input.

DIGITAL connectivity

Three inputs to the 24 bit

192kHz DACs are provided,

along with a USB connector

for use with a computer.

Remote

STREAM III

Remote

1. POWER - The power button toggles Stream III between On and Standby. If a

LIPS connection is used, the power status of any other Leema components

connected via LIPS will also be controlled.

2. TRAY - The tray button ejects the disc if loaded.

3. INPUT -/+ If the systems includes a Leema amplifier, these buttons are used

to cycle through the available amplifier inputs. If a LIPS connection is used,

the amplifier may be out of sight of the remote, in an air conditioned

cupboard for example. If LIPS is not used, the remote will command the

amplifier using infra-red.

4. VOLUME -/+ The volume level of a Leema amplifier product may be

controlled from the Stream III remote. If a LIPS connection is used, the

amplifier may be out of sight of the remote, in an air conditioned cupboard

for example. If LIPS is not used, the remote will command the amplifier using

infra-red.

5. PLAY - The play button also provides a pause function if the disc is already

running. Tracks may be ‘queued’ by selecting pause and then NEXT/PREV to

queue the required track.

6. STOP - Stops the disc. Pressing stop repeatedly, while the disc is already

stopped, will cycle through the DAC external digital inputs.

Remote STREAM III

7. PREV - If SCAN is not selected, the PREV button decrements the track selection. If SCAN is selected, PREV becomes SCAN

BACKWARDS (<<).

8. NEXT - If SCAN is not selected, the NEXT button increments the track selection. If SCAN is selected, NEXT becomes SCAN

FORWARD (>>).

9. SCAN - This button toggles between normal play and scan mode. In scan mode, the NEXT and PREV buttons function as

SCAN FORWARD (>>) and SCAN BACKWARDS (<<). It is also possible to exit SCAN, by pressing PLAY.

10. MUTE - Leema amplifiers may be muted with this button. Again, it is available in LIPS or infra-red modes.

Front Panel Operation -Front panel control is via a navigation style switch cluster. The cluster has up, down, left,

right and centre (standby) buttons.

1. Standby -

any other Leema components connected via LIPS will also be controlled.

2. PLAY/PAUSE - Pressing the top button once will start playback. Pressing a second time places the unit in PAUSE.

3. NEXT/PREV - Pressing the right & left buttons will select the next and previous track. Pressing the buttons before the disc is

playing will scroll the track number allowing fast access to higher numbered tracks.

4. SCAN - If the disc is already playing, pressing and holding the NEXT/PREV buttons for a few seconds, will enter high speed

SCAN forward and backwards. Pressing PLAY will cancel SCAN mode.

5. STOP - Pressing the lower button while the disc is playing, will stop the disc.

6. EJECT - If the disc is stopped, pressing and holding the bottom button will eject the disc.

7. DAC Input - If the disc is stopped, repeatedly pressing the bottom button will cycle through the DAC external inputs.

8. LIPS Modes - Pressing the left & right buttons simultaneously when in STOP will enter the LIPS mode editor. The LIPS modes

may then be selected by using the left or right buttons. After a few seconds, the editor will exit and the machine reverts to

normal operation. See LIPS for more details.

9. REPEAT Modes - Pressing the up & down buttons simultaneously when in STOP will enter the repeat editor. The repeat modes

may then be selected by using the up or down buttons. After a few seconds, the editor will exit and the machine reverts to

normal operation. The repeat options are: NORM - Normal Play, SHUF - Shuffle All, SRPT - Shuffle Repeat All, RDSC - Repeat Disc

and RSNG - Repeat Song.

The Standby button toggles Stream III between On and Standby. If a LIPS connection is used, the power status of

Connections

Output

Connect the Left and Right outputs to your amplifier CD input using good quality phono-to-phono (RCA) interconnects to

provide maximum audio performance.

Digital connections

SPDIF coaxial digital output > This output provides a transformer isolated standard Sony/Philips digital interface. Use a good

quality cable designed for SPDIF applications. Audio cables must not be used as they will seriously degrade the data stream.

OPT 1> This input may be connected to digital optical outputs carrying a SPDIF (PCM) stereo data stream, such as satellite TV

boxes etc. Ensure that the data stream is not multi-channel, such as AC3. The DAC can decode all data rates up to

24bit/192kHz, however 176.4kHz is not supported.

OPT 2> As OPT1.

SPDIF >This input may be connected to digital coaxial outputs carrying a SPDIF (PCM) stereo data stream, such as satellite TV

boxes etc. Ensure that the data stream is not multi-channel, such as AC3. The DAC can decode all data rates up to

24bit/192kHz, however 176.4kHz is not supported.

USB >A computer may be connected here for playback or recording. The USB codec supports formats up to 16bit/48kHz. It

may be used for streaming playback or for recording CD playback in the digital domain.

Connections STREAM III

LIPS

The LIPS cables are directional and must be connected the right way round for the system to operate. No harm will be done if

cables are connected the wrong way round, the system will simply not work correctly. The black plug is inserted in to the

sending unit and the red plug in to the receiving unit. The chain will normally be:

Player (e.g. Stream) > Amplifier (e.g. Pulse) > Accessories

If a home automation controller is to be installed, the order would be:

Controller > Player > Amplifier > Accessories

This type of installation can be quite complex and is best performed by a Leema dealer.

In a basic system comprising two audio units, the LIPS cable will be arranged as follows:

Black (Stream) > Red (Pulse)

The following section is intended for installers, system integrators and third party manufacturers.

What is LIPS?

LIPS or Leema Intelligent Protocol System, facilitates communication between various items in a Leema audio system. It

allows units such as Tucana, Antila, Pulse or Stream to control other items in a chain. Leema’s constellation 5.2 surround

system is a good example, where a Tucana controls a Hydra and Corvus. Key information including volume level, input

selection and power control is passed through the bus enabling other units to operate in synchronisation. Intelligence is

added within each receiving unit, for example, a Hydra installed as part of a surround system ‘knows’ that it won’t be required

when listening to a stereo source such as CD. Therefore, when the Hydra ‘sees’ the CD input, it powers itself down.

LIPS

STREAM III

LIPS modes STREAM III

Each Leema unit can be controlled via the LIPS bus. Controlling a Stream III externally for example, enables it to be used

within a home automation system.

LIPS Specifics

The LIPS bus is driven by an open-drain output. Leema can supply interface modules as required. The communication

standard follows the common RS232 format of No Parity, 8 data bits and 1 stop bit. The baud rate is 38400.

LIPS Packets

Each communication on the LIPS bus contains a packet of four data bytes as follows:

First a header is sent with a value of 255. This alerts the receivers to incoming data.

Next, a command header is sent.

Next, a value relating to the command is sent. For volume this would be 0 to 248.

Finally a tail byte is sent with a value of 0.

LIPS Protocol Headers For further information, please contact Leema Technical Support.

Additional functions

In addition to the normal functions as detailed in the user manual, Stream III has a number of 'hidden' edit functions. At the

time of writing these pertain to LIPS modes and disc repeat modes.

LIPS modes

Stream III may be used as a master to control other Leema components or as a slave to be controlled by other equipment.

Disc repeat modes

STREAM III

To enable these various modes, an edit menu is used to select the appropriate setting.

To enter the edit mode, with the unit stopped, press the left & right buttons simultaneously. The LIPS modes may now be

cycled through by repeatedly pressing the left or right button. If the buttons are not pressed for a few seconds, the edit mode

is exited and normal operation is resumed.

The modes are displayed in the display as follows:

Disc repeat modes

Stream has the ability to repeat tracks or complete discs as required. To enable the repeat modes, an edit menu is used to

select the appropriate setting. To enter the edit mode, with the unit stopped, press the up & down buttons simultaneously. The

repeat modes may now be cycled through by repeatedly pressing the up or down button. If the buttons are not pressed for a

few seconds, the edit mode is exited and normal operation is resumed.

The repeat modes are displayed as follows:

NORM - Normal Play, SHUF - Shuffle All, SRPT - Shuffle Repeat All, RDSC - Repeat Disc and RSNG - Repeat Song.

OFF This is the default setting and should be used when the player is being used on its own as a normal player.

SLAV LIPS slave mode. This allows the player to be remotely controlled via a LIPS interface unit.

TUC1 Master mode to control a Leema Tucana MKI.

TUC2B Master mode to control a Leema Tucana MKII - Stream III connected to the Balanced input. (RCA to XLR cable)

Infra-red codes

The following codes may be used to program universal remotes using Sony 12 bit protocol:

IR DEVICE = 17 (Stream/Antila specific)

16 = LIPS INPUT INCREMENT, 17 = LIPS INPUT DECREMENT, 21 = POWER TOGGLE, 22 = EJECT, 48 = PREV, 49 = NEXT,

50 = PLAY, 56 = STOP, 57 = PAUSE, 59 = SCAN TOGGLE

For direct track access (as per Sony CD1 format)

32 = num 0, 0 = num 1 ..... 8 = num 9, 39 = +10

The above are used as follows: +10, num, num e.g. +10,1,2 = track 12 etc.

In addition to Stream specific codes, the player is able to process amplifier codes for communication via LIPS:

IR DEVICE = 16 (Amplifier, e.g. Tucana etc.)

0 - 6 = INPUTS 1 - 7, 16 = INPUT UP, 17 = INPUT DOWN, 18 = VOLUME UP, 19 = VOLUME DOWN, 20 = MUTE TOGGLE

21 = POWER TOGGLE
