Thank You

Your decision to purchase this Luxman M-800A Amplifier singles you out as one of the most discriminating music listeners. Luxman has been hand-crafting exquisite audio reproducing equipment in Japan since 1925. Luxman's relentless dedication to Quality is your assurance that you will receive many years of musical enjoyment from this unit.

Please take a short time to read the information in this manual. We want you to be as familiar as possible with all the features and functions of your new Luxman.

Front Panel Controls

Diagram Description: The front panel features several controls and indicators. Numbered callouts point to: 1. Power Indicator (LED), 2. Power Stand-by / ON button, 3. Operation Indicator (LED), 4. Balanced Input selector button, 5. Balanced Indicator (LED), 6. Output Meters, 7. Display Mode Switch, 8. BTL (Mono) Status Indicator (LED).

1. Power Indicator: LED blinks gently initially to show warming up, shines constantly when the M-800A is fully operational. Yellow in stand-by, blue when operational.
2. Power Stand-by / ON: Push button turns the amplifier ON or OFF (stand-by).
3. Operation Indicator: LED glows blue to show that the amplifier is operational.
4. Balanced Input: This is the input selector. Depress the button to select the Balanced input.
5. Balanced Indicator: Blue LED shows that the Balanced input is active.
6. Power Meters: Indicate the power delivered to the loudspeakers. The meters respond to all the musical information being produced by the amplifier.
7. Display Mode Switch: Toggles between varying intensity of the Power Meters and finally turns them off completely. Pushing the button again cycles through the modes.
8. BTL (Mono) Indicator: Blue LED shows that the Bridged Monaural output is engaged.

Rear Panel Controls

Diagram Description: The rear panel provides various connection terminals and controls. Numbered callouts point to: 9. Power Socket (AC), 10. Line Phase Sensor, 11. Power Switch (ON/OFF), 12. Remote On/Off, 13. RCA Inputs, 14. Balanced Inputs, 15. Speaker Terminals, 16. Grounding Post, 17. Stereo / Mono BTL switch.

9. Power Socket (AC): Connect the M-800A power cord to a live AC outlet. Caution: The supplied AC Power Cord should not be connected until after the Loudspeaker Connections have been made. Failure to observe this could result in Electric Shock.
10. Line Phase Sensor: This device checks the phase of the AC electricity. If the AC outlet is incorrectly wired (live and neutral swapped), a red LED will turn on to warn you. Press it once during installation to check wiring.
11. Power Switch (ON/OFF): It is safer to turn the mains power off when not using the amplifier for a prolonged period or during a lightning storm. However, the amplifier may be left on in the standby mode for prolonged periods safely.
12. Remote Trigger ON/OFF: Receives a 12-volt DC trigger from a LUXMAN C-1000f, C-800f, or C-600f to toggle between Stand-By and Operate. Uses a simple RJ-11 connector.
13. RCA Inputs: Standard input connectors for unbalanced audio signals.
14. Balanced Inputs: XLR inputs desirable for minimizing earth loop generated mains hum and ripple, or high frequency interference.
15. Speaker Terminals: Connect the right speaker to the terminals marked 'R+' and 'R-', ensuring 'R+' connects to the '+' terminal on your loudspeaker and 'R-' to the '-' terminal. Connect the terminals marked 'L+' and 'L-' to the left speaker similarly. Always use heavy-duty (16 gauge; 1.5mm, or thicker) stranded wire. The high-current binding post terminals can be used as screw terminals for cables terminating in spade or pin sockets, or for cables with bare wire ends.
16. Grounding Post: This terminal does not have to be used, but you may connect it to a suitable ground, which under some circumstances will reduce hum and ripple.
17. Stereo / BTL Mono: While inputs are summed when using the BTL switch (Bridge Tied Load) or bridged monoblocks, please be aware that a different speaker hook-up is required for Mono use from the normal Stereo configuration.

Note on Polarity: Please take care to observe the correct polarities. Otherwise, one or both speakers might be out of phase. When both speakers are out of phase, for example, the singer will not be clearly defined in the center of the soundstage, but smeared across the center. Bass will not be as taut.

How to Connect Loudspeakers

Prepare the Loudspeaker Hookup Cables by choosing one of the methods below:

Bare wire Cable:

Carefully remove sufficient insulation from the cable ends. If the cable is stranded, carefully twist the strands together as tightly as possible. The twisted ends can be tinned with solder to keep the strands together, or attach spade lug or banana connectors.

Spade Lug:

Insert the spade lug connector or prepared section of the cable end into the terminal side access hole, and tighten the terminal cap until the cable is firmly clamped into the terminal so the wires cannot slip out.

Banana Plug Connection:

Remove the black plastic cap in the center of the speaker terminal and insert the banana plug.

Note on Polarity: Please take care to observe the correct polarities. Otherwise, one or both speakers might be out of phase. When both speakers are out of phase, for example, the singer will not be clearly defined in the center of the soundstage, but smeared across the center. Bass will not be as taut.

Installation

The M-800A can be placed upright on a table (amplifier stand) or shelf, standing on its four feet. It also can be custom installed in a piece of furniture or cabinet of your choice.

Always provide adequate ventilation for your M-800A. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the M-800A directly above a heat generating component such as a high powered amplifier. If all the components are installed in a single cabinet, a quiet running ventilation fan should be utilized to maintain all the system components at the coolest temperature.

Allow at least 6 feet above the amplifier, 2 inches all around.

XLR Balanced Connection Pin Out

Diagram Description: An XLR connector is shown with three pins labeled: Pin 1, Pin 2, and Pin 3.

Normal Configuration:

1. Ground
2. Cold (-)
3. Hot (+)

Reverse Configuration:

1. Ground
2. Hot (+)
3. Cold (-)

In the USA, most balanced products use Pin 2 = Hot or + (this is the reverse switch setting).

Connections

Stereo Configuration

Diagram Description: This diagram illustrates the stereo connection setup. A CONTROL AMP is shown connected to a CD/DVD-A PLAYER and a CD/SACD PLAYER via RCA cables. The Luxman M-800A amplifier is connected to the CONTROL AMP using input cables (likely RCA or balanced, though the diagram focuses on the amplifier's rear). The amplifier's speaker outputs are connected to a SPEAKER SYSTEM (Left and Right speakers). The power cord is shown connecting to an AC outlet.

Mono Configuration

Diagram Description: This diagram illustrates the mono (BTL) connection setup using two Luxman M-800A amplifiers. A CONTROL AMP is connected to both amplifiers. Source components (CD/DVD-A PLAYER, CD/SACD PLAYER) are also shown connected to the amplifiers. The two amplifiers are configured for BTL (Bridged Tied Load) operation. The speaker outputs from both amplifiers are connected to a single SPEAKER SYSTEM (Left and Right speakers), with specific connections for bridged mode indicated.

M-800A Block Diagram

Diagram Description: The block diagram outlines the internal architecture of the M-800A amplifier. It shows the AC input feeding into the power supply section, which includes transformers, rectifiers, and regulators for various voltage rails (+B1L, -B1L, etc.). A Line Phase Sensor and Power Switch control the AC input via relays. The signal path includes input selection (balanced/unbalanced), input buffer amplifiers, the ODNF (Only Distortion Negative Feedback) circuit, main amplification stages, and output stages. The BTL amplifier configuration is shown for mono operation. Control circuits manage operation, mute, protection, and indicators. Speaker outputs are connected to the speakers, with protection circuits in place.
