PACKAGE CONTENTS
• Leon OTO MCA 200 Amplifier
• OTO MCA 200 IR Remote Control
• AC Power Cord
Congratulations on your purchase of a Leon OTO MCA 200. This was
developed in collaboration with AudioControl®, 40-year veterans of the
performance-audio amplifier industry. The features of the OTO MCA 200
allow it to shine in both analog and digital audio systems, whether in an
audiophile stereo system, a home theater, or a commercial environment.
The amplifier includes a high-performance Wolfson® DAC (digital to analog
converter), and comfortably delivers 100 watts per channel at 8 ohms, 200
watts per channel at 4 ohms, or up to 400 watts bridged.
Additionally, the amplifier features options for control via IR remote, or via
RS232 for easy integration with third-party control systems. With integrated
switchable crossovers, multiple OTO MCA 200 amplifiers can be combined to
drive passive 2.1 systems. The AccuBASS® function allows detailed control
over bass response to help simplify speaker placement and tuning of the
room.
This manual will take you step-by-step through the features and operation of
the OTO MCA 200. Please read it thoroughly and carefully to ensure that you
get maximum performance from the OTO MCA 200. Keep this manual in a
safe place in case you need to refer to it in the future.

IR REMOTE CONTROL TOUR
A. Power On/Standby: Press this to awake the OTO MCA 200, or put it into
standby mode. In standby, the OTO MCA 200 will use minimal electricity.
During normal operation, the OTO MCA 200 will enter standby if no input
signal is sensed for about 8 minutes. This auto-standby mode can be
disabled using the Sleep Defeat DIP switch (see Pages 11-12). If the Power
On/Off switch is off, the amplifier will not turn on with the remote control.
B. Volume Up/Down: Press the plus button to increase the volume, and
the minus button to decrease the volume.
C. Mute: Press this button to mute or unmute the amplifier output.
D. Input Selection 1, 2, 3: Press these buttons to select the desired input.
The OTO MCA 200 front panel LED will light to reflect the selected input.
E. Headphones On/Off: Press this to turn on/off the OTO MCA 200
headphone output. All other outputs will be muted and the front panel
headphone LED will light when the headphone output is engaged.
F. AccuBASS® Up/Down: Press the arrows to increase or decrease the
amount of AccuBASS® enhancement.
G. AccuBASS® On/Off: Press this to turn on the AccuBASS® enhancement.
The front panel input LED will glow brighter when AccuBASS® is enabled.
H. Battery Compartment: The battery compartment on the back is
opened by pressing and sliding off the small cover. Remove a small
insulating strip from below the battery before first use. Always replace the
battery with the exact same type (3V lithium CR2032), and with the positive
(+) side facing outward.

3. Input Selection LEDs: These three LEDs indicate which input is
selected. Inputs 1 and 2 are digital inputs, and input 3 is analog. When the
OTO MCA 200 is muted, all input LEDs will be off. When the OTO MCA 200
receives a command from the IR remote or via RS232, the input LED will
flash. The selected input LED glows dimly under normal conditions, and
brighter when the AccuBASS® setting is enabled.
4. Headphone On/Off LED: This LED indicates if the OTO MCA 200
headphone output is enabled. When the headphone output is turned on,
all other outputs from the amplifier are muted. The headphone output is
controlled via the IR Remote.

6. Power On/Off Switch: This is the master power switch for the OTO MCA 200
amplifier. Keep the amplifier off while making connections or disconnections
from the amplifier. Use this switch to turn the amplifier off if it will not be used
for long periods of time.
7. Voltage Selection Switch: Ensure this is set to your region-specific line
voltage before plugging in the OTO MCA 200.
8. RS232 Control Input: Use this terminal block to connect a third-party
control system. The pins are as follows:
• Pin 1 – RX (RS232 receive)
• Pin 2 – Ground
• Pin 3 – TX (RS232 transmit)
9. Amplifier Control DIP Switches: These DIP switches affect the operation of
the amplifier. See Pages 11-12 for more details.
10. Speaker Outputs: Use this Euroblock terminal block for connections to
your speakers. Make a note of the polarity markings and ensure they match
those of your speakers (+ to +, - to -).
11. IR Output: This 1/8” jack allows a remote IR sender to be connected.
12. Bridged Mono Output: When the OTO MCA 200 is in bridged mode, this
RCA connector outputs the signal from the active input’s right channel only.
It is affected by the volume level, AccuBASS® level, and the 80Hz low-pass
crossover.
