Using The Controls/ Back Panel

Power

Using the controls/ Front Panel

Power

The front panel switch will manually switch the MI5 Powered
Amplifier on or off. A blue led behind the faceplate lens indicates its
power status. Whe never the amplifier’s power switch is in the “ON”
position and the amplifier is in ”active” status the lens is illuminate
blue. If the amplifier is “ON” but in the “standby” status the lens is
illuminated RED.

The MI5 Powered Amplifier can be turned on and off independently
via a switc h on the front panel, by signal sensing, or remotely by a
triggered DC input. There is a switch located on the lower edge of
the rear panel of the amplifier to select how you would like to turn
on the MI5 pow er Amplifier. If you would like to cont rol the unit’s
power On/Power off status manually from the front, place the
switch in the unit’s power On/Power off status by means of signal
sensing, place the switch in the “ Auto On” position. If you would
like to control the unit’s power On/Pow er off status by a DC
Remote trigger, place the switch in the ”TRIGGER” position, and
connect the remote triggering device to the terminal labeled “
TRIGGER IN” next to the switch.

You should use a 3.5mm phone plug in the “IN” connector to make
this connection. The tip of the connector is positive, and the sleeve
of the connector is negative. A second terminal in the same block is
labeled “OUT”. This allows for remote turn-on of other devices
when the MI5 powered Amplifier is powered on. Use the same
polarity for the terminals of this plug. Please read the owner ’s
manual for any devices you are attempting to connect in this
manner to ensure compatibility.

Note: The front panel power switch must be in the “ON”
Position for the triggers or “Auto ON” features to operate.

Master Level Control

Each channel is able to control its volume independently relative to the
other channel. At the bottom left of the rear panel, there are 2
screwdriver adjustment knobs which correspond to the volume level of
the channel identified by a channel designator below it.

The volume range is labeled Minimum to Maximum and has 1 steps
(clicks) at a center position as a reference. Rotate the knob clockwise
to increase output, and counter clockwise to decrease output.

These adjustments set the master level and if not set up an initial setup
of the MI5 Powered Amplifier will or may adversely affect the
performance of the amplifier.

To set the Master Lever controls begin by adjusting the front panel
“Volume Trim” to its fully clockwise position. Also set the front panel
“Balance Trim” to its center position. Now adjust both the left and Right
Channel Master Level controls to set a “Maximum” desired volume for
the MI5 Powered Amplifier in its application, as well as setting an
appropriate “Balance” from left to right.

Now the front panel Volume and Balance Trim controls can make fine
adjustments to your set up in this application.

RCA input

As an example, if the “line 1 Input” source was a CD Changer, The delay
could be adjusted to prevent switching back to the “Line 2 Input” source
while the changer moves from one disk to another.

Speaker Level Input

The MI6 Powered Amplifier also provides a pair of speaker level input
for those applications where either of the sources has only speaker
level output signal available. This input may be switched to be used in
place of the line 1 or line 2 input.

Mode Switch

To the right to the master Level controls is a switch labeled “MODE” with
“STEREO” and “BRIDGED” as options. If you will be connecting one or
two pair of speaker to the amplifier, place the switch in the “STEREO”
position.

If you will be suing a pair channel to power a single mono speaker,
place the switch in the “BRIDGED” position, and be sure to read the
section titled “Speaker Terminals” below.

When you are using the amplifier in “Bridged Mode”, the amplifier is
now a single channel mono amplifier. The two channels have been
internally connected in series by the “Bridge” switch. The MI6 Powered
Amplifier is now capable of 250W, bridged into 8 ohms with less than

0.2% THD+N.

There are a total of 4RCA inputs on the back panel of the MI5 Powered
Amplifier. These RCA inputs are labeled as “Line 1 Input” and “Line 2
Input”. They are also designated with an “R” or an “L” as Right channel
or Left Channel inputs respectively.

“Line 2 Input” should be used as the “primary” or normal input for
various line level sources that may be available locally to the amplifier.
“Line 1 Input” is a priority switching input that can be used for a second
input, such as, the output of a second source, and will take over as the
primary input whenever a signal with a minimum of 5mv of level is
present. Whenever, there is an absence of signal at the “Line 2 Input”
RCAs input signal. An adjustable delay of from 3 motet the nature of
the source connected to the “Line 1 Input” RCAs.

For the amplifier to operate properly in the bridged mode you should
have both the “right and left” inputs connected to the amplifier. The
amplifier will sum these signals and create your mono source.

Note: This Amplifier will produce excess of 200 watts with a
bridge pair of channels. Please verify that your speaker are

capable of handling suck power to avoid possible damage!

Speaker Terminals

Each channel has two pair of multi-way binding post. These are the red
and black screw posts on the rear of the amplifier. Terminals are
provided for “A” and “B” Pairs of speaker for each channel. If you will
be suing the amplifier as a stereo amplifier (not a bridged amplifier) you
will connect the speakers positive (Red) terminal to the amplifiers
positive (Red) terminal using the appropriate gauge speaker wire, and
the speakers negative (Black) terminal to the amplifiers negative
(Black) terminal (immediately below the positive terminal) using the
appropriate gauge speaker wire. If you would like to use on pair of
channels bridged, place the “mode” switch in the “bridged” position and
use both red terminals to connect to the speaker. (See illustration on
page 5)

Applications
Powering Speaker Outdoors

Whenever you are using loudspeakers outdoors, you should be
Aware that sound does not travel like it would in your home.
Without the reflective surfaces of walls and ceilings, sound outdoors
will dissipate quickly. Therefore, in an outdoor situation the MI6
Powered Amplifier provides the opportunity to bridge adjacent
channels, effectively doubling the available power for your speakers,
This can help to overcome the problem of using speakers outdoors
assuming the speakers chosen are capable of handling the additional
power.

It should be noted th at the MI6 Power ed Ampli fie r is rated to
ope rat e into minimum 8 -ohm bridged l oad. T her efore, if y ou
are usi ng more th an single 8-ohm loud spe aker in bridged m ode you
should consider using an impedan ce matching speaker selector,
such as the SV CC-6 or possibly usi ng an impedance matching
volume co ntrol, su ch as the SVC-3 00, VKR-120 or VMS-3 00 in a
weatherpro of hou sin g a vailable at your favorite DIY s tor e o r e lec tri ­cal supply. The ch oic e of a volume co ntrol would allow you the
additional fl exibility of bei ng able to attenuat e t he volume whenev er
necessary.

Stereo Setup

In this configuration, the mono switch is set to stereo for stereo
operation. Connect the line out jacks from a stereo preamplifier or
source to the Line 2 input jacks of your MI5 Powered Amplifier. Next
connect your speakers to the terminals marked “SPEAKER A”
observing proper polarity (see “speaker terminals” Page 5). Connect
a second (optional) pair of speakers to the terminals marked
“SPEAKER B”. Select between the “A” and or “B” speakers using
front panel speaker selection buttons.

Mono Setup

In this configuration, the mono switch is set to bridged. Connect the
line out from a preamplifier to the right and left Line 2 input of your
MI5 Powered Amplifier. Connect your mono speaker to the terminals
of your MI5 Powered Amplifier, following the instructions in “Speaker
Terminals” on Page 4. Use the “Master Level” controls on the rear
panel to adjust the volume. Leave the balance set to the center
detent position.

The distributed audio is then passed on to be used by additional zones
or sub zones in the distributed system via the Line 2 outputs. The
Audio output of a local source, such as MP3 Player, CD, television,
computer, etc.. Is connected to the MI5 Powered Amplifier via the
television, computer etc.. Is connected to the MI5 Powered Amplifier
via the Line 1 inputs, and whenever the local source is active its signal
will take priority over the distributed audio signal present at Line 2.
However, the distributed audio signal will still be present at the Line 2
input. In this circumstance the audio output of the local source will be
heard via the MI5 Powered Amplifier. Once the local source is turned
off or muted, the MI5 Powered Amplifier will automatically switch back
the distributed audio system as an audio source, assuming the
television is remains inactive. The delay time adjustment determines
when switch back to the normal source will occur.

This set up assumes all incoming signals are at line level and not at
speaker level. If the Whole House Distributed Audio was only available
as a speaker Level signal you could connect it the “speaker In”
connections and set the switch above to the “Line 2” position, or
toward the right hand position of the switch.

Setup For Multiple Sources

In the application shown below, a distributed audio system is
connected to the MI5 Powered Amplifier as a local zone amplifier via
the Line 2 inputs. Normally the distributed audio system will be the
audio source for the MI5 Powered Amplifier.

The distributed audio is than passed on to be used by additional
zones or sub zones in the distributed system via the Line 2 outputs.

If you have any questions regarding how to set this up, please call
OSD AUDIO support at [phone].
