Line Level Inputs
90-
See Figure 3
The CD, Tuner, and Aux inputs of the control amplifier are analog “line level”
inputs. These inputs are for connecting components such as CD players or
other audio playback devices with an analog audio output.
The left and right channels are clearly labeled and should be connected to
the corresponding channels of the source component. The Left connectors
are white, the Right connectors are red. Use high quality RCA cables for
connecting input source components to the P5. Ask your authorized Michi
dealer for advice about cables.
Balanced (XLR) Inputs
7
See Figure 4
Two pairs of balanced XLR inputs accept audio signals from CD player, Blu-ray
player or other source components with XLR outputs.
NOTE: You should choose only one method of analog connection from a
source component to P5. Do not connect both the RCA and XLR outputs
of a source component to the P5 at the same time.
Digital Inputs
t
See Figure 5
There are three sets of digital inputs labeled 1, 2 and 3, for COAXIAL and OPTICAL
respectively. Connect the COAXIAL or OPTICAL PCM outputs of your source
component into these sockets. The digital signals will be decoded and played
by the P5. The unit is capable of decoding PCM signals up to 24 bit, 192kHz.
Output Connections
Line Output
=
The line output connectors can be used to send the analog audio to a separate
processor device. These outputs bypass the volume encoder and are full line
level output. They should be connected to the analog inputs of the processor.
As with other sources be sure to connect the Left and Right channels of each
device to the proper channels on the associated components. Use high quality
connecting cables to prevent loss of sound quality.
MONO SUB Output
q
There are 2 connectors for mono subwoofer output to connect to a subwoofer.
These mono outputs are summed with both the left and right audio signal.
They are parallel outputs allowing 2 subwoofers to be connected to the P5.
Preamp Output w
See Figure 3
The P5 RCA-type output connectors are compatible with most power control
amplifiers. As always, select high quality audio interconnect cables. Connect
the left and right channel outputs of the P5 to the corresponding inputs on
the amplifier or other component.
NOTE: There are two sets of RCA outputs on the P5. The second set of
outputs may be used in custom system configurations to drive a second
power amplifier or to supply a signal to a special signal processor.
Balanced (XLR) Output
e
See Figure 4
Two pairs of XLR balanced connectors supply an analog output signal from
the P5 to a power amplifier with XLR balanced input connectors.
NOTE: Do not connect both the RCA and XLR to the same control
amplifier at the same time.
Digital output
y
If you are using an outboard D/A converter or other digital processor, you will
need an unprocessed digital data stream from the P5. Using a standard 75
ohm coax/optical digital cable, connect the P5’s digital output to the digital
input connector on the outboard D/A converter.
Headphone Output
6
The headphone output allows you to connect headphones for private listening.
This output accepts a standard 6.3 mm (1/4”) stereo headphone connector.
Plugging in a set of headphones does not cut off the signal to the preamp
outputs. In most instances you should turn off the power control amplifier
when listening to headphones.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.
Bluetooth Connection
\
The Bluetooth Antenna
\
on the P5’s back panel is for wireless streaming
via Bluetooth from your device (i.e. mobile phones). From your mobile device,
look for “Michi Bluetooth” and connect to it. Connection is normally automatic,
but if prompted for a password, please press “0000” on your device. The P5’s
supports traditional Bluetooth, AAC and APTX Bluetooth audio streaming.
Rear USB Power Port
[
The rear USB port provides 5V/0.5 amps for charging or powering USB devices
including streaming music players. This port does not allow playback of audio.
The port can be configured to remain powered even when the P5 is in standby
mode through the front panel Setup menu (See USB Power part on page 16).
This configuration option allows the attached streaming source to remain
powered for use with the Signal Sense function for automatic power on/ off
control of the control amplifier.
NOTE: When configured to provide continuous power to the rear panel
USB port the P5 will consume additional power even when in standby
mode.
EXT REM IN Jack
o
This 3.5 mm mini-jack receives command codes from industry-standard infrared
receivers via hard-wired connections. This feature could prove useful when
the unit is installed in a cabinet and the front-panel sensor is blocked. Consult
your authorized Michi dealer for information on these external repeaters and
the proper wiring of a jack to fit the mini-jack receptacle.
RS232
]
The P5 can be controlled via RS232 for integration with automation systems.
The RS232 input accepts a standard straight DB-9 Male-to-Female cable.
