MICROZOTL MZ3

Small and mighty. The highest expression of the patented microZOTL technology as a headphone amplifier, a preamplifier, and integrated amplifier in a desktop-sized package.

The result of three years of refining our flagship headphone amplifier, the award-winning microZOTL MZ2. The MZ3 is the highest expression of the patented microZOTL technology as a headphone amplifier, a preamplifier, and integrated amplifier in a desktop-sized package.The MZ3 has a beautiful new low-resonance aluminium chassis and offers reference-level sonics through upgraded internal components, premium tubes, and a digital control system with LED display.

Key specifications:

Inputs: 3 Stereo single ended RCA high quality connectors using sealed, silver contact relay control for a short signal path

Outputs: Headphone ¼” Phone jack, Dual preamp RCA outputs single ended, Stereo speaker binding posts

Amplifier class: Push-pull Class A, no feedback

Sensitivity: 0.6V RMS [full output]. Output impedance: (measured @ 0.5A, 60 Hz) 2 ohms for headphone and speaker outputs, 50 ohms for preamplifier outputs. Input impedance: 50k. Volume Control: Stepped attenuator constructed of 1025 steps of 50 ohms, with 100 positions selected to provide very fine resolution at the lowest volumes and a logarithmic control for higher volumes . Low noise, precision 1% Vishay Dale resistors and hermetically sealed silver contact relays are used for precise, isolated analogue signal attenuation. Balance Control: 100% channel isolation using stored differences of volume values. Maximum balance differential is 16 steps

Power Supply: Linear supply user-switchable between 110/120 and 220/240 (100V linear supply available for Japan). Uses dual banks of organic poly ultra low ESR capacitors (4 times MZ2) for over 100KuF of output choke isolated storage. Oversize transformer secured with aluminum and brass mountings (no steel). Regulation is performed using low noise Belleson super regulators. Current transformer controls output protection circuit

Power Supply Output:  12VDC 3 amp. Power Supply Umbilical Cable: premium low noise shielded cable with silver contact, spring loaded premium XLR connectors

Hum and noise: minimum 60mV RMS or 90dB below full output (20Hz-20kHz). Power consumption from ac power source: approx. 50W

Power output: with 4-ohm load: 1W, 1% THD, with 14-ohm load: 0.5W, 1% THD. Channel separation: (4-ohm loads) 46dB, 100Hz-10kHz, (14-ohm loads): 54 dB, 100Hz-10kHz. Frequency response full power: (4-ohm load) +0, -1dB 10Hz-20kHz, (14-ohm load): +0, -1dB 5Hz-50kHz. Voltage gain:  (4-ohm load): 10.3dB, (14-ohm load): 12.4dB

Front Panel Control: Functions include volume, input select, headphone/speaker output select, and amplifier power on-off.

Remote Control: All functions, including Mute and the configuration menu, are available from the remote, except power on-off and headphone/speaker output selection. Uses an Apple TV remote.  The remote is registered to unit to limit control from unintended remotes. The Right-Left buttons can be configured as balance controls.

Auto-save Features: Volume level per input is automatically saved and the unit powers on using the stored volume levels. Balance and all other configuration menu selections are all saved as a global level across all inputs. Display Controls: 16 levels of brightness and on-off selectable 7 second timeout.

Home Theater Mode: an input can be selected from configuration menu to set one of the inputs to a high volume level fixed input to allow surround sound device control the volume leve.

 

Size: Amplifier: 10 inches (25.5 cm)wide, 4 3/4 inches (12.0 cm) tall, 8 1/2 inches (18 cm) deep. Linear power supply: 12.25" (31 cm) long x 5.25" (13.5 cm) wide  x 4.25" (11 cm) tall. Net weight: Amplifier Unit 6 lbs. 15 oz. (3.15 kg.)  Power Supply 5 lbs. 3 oz. (2.45 kg.) Shipping weight: 17 lbs. (7.7 kg.).

 

Tube complement: 2 premium hand selected 12AT7 input tubes, and two premium hand selected 12SN7 output tubes.  (6SN7s can be used with jumper settings) 12AU7s are often substituted for the 12AT7s to lower the gain if higher headphone output is not required. 

Speaker sensitivity & room recommendation.

LTA amplifier owners have found great enjoyment using their amps with a variety of speaker outside of the below ranges. The below are guidelines, not rules. If you have questions about your specific speakers, chances are someone we know has tried them. Don’t hesitate to reach out with questions about your specific setup.

Critical listening environments: 105db sensitivity and above

Smaller rooms / lower volume levels / non-critical listening: 95db sensitivity and above.

Also, don’t forget we have a 14-day no-questions-asked return policy.

A couple of reviews & Videos:

I can’t say that I’m completely shocked that the new Linear Tube Audio Mz3 is such a great preamplifier. However, even with all of the great and expensive preamps I have had in my system over the years, I was still astounded at the level of improvement the MZ3 brought. The Audio Beatnik - Preamp Review // Integrated Amp Review

“My MZ3 has now really burned in well and has moved into the magical stage. You have to hear the sound to believe it. The very best, hands down, of any amp I have ever heard and pure magic. Sometimes it is so distracting I have to take the phones off to concentrate what I am doing. I find I just stop stare into space and listen and sometimes, I don't have time for that. Really. But hey, I will make the sacrifice at times. lol But it really has to be heard but does take some hours to get there but so very much worth it.”
