Performance
Frequency Response: ±0.1 dB from 20 Hz to 20 kHz at 1 watt.

Phase Response: ±10° from 10 Hz to 20 kHz at 1 watt.

Signal-to-Noise Ratio: (A-weighted) Greater than 105 dB below rated continuous average output from 20 Hz to 20 kHz. (No weighting) 100 dB below rated continuous average output from 20 Hz to 20 kHz.

Harmonic Distortion (THD): Less than 0.05% at rated output from 20 Hz to 1 kHz, increasing linearly to less than 0.1% at 20 kHz.

IM Distortion (IMD): Less than 0.05% from 10 milliwatts to full rated output.

Damping Factor: Greater than 1,000 from 10 Hz to 400 Hz.

Slew Rate: Channel 1, greater than 30 volts per microsecond; Channel 2, greater than 13 volts per microsecond.

Voltage Gain: 20:1 ±6% or 26 dB ±0.25 at +26 dB input sensitivity and the maximum level setting. The sensitivity varies by model and channel when the input sensitivity is set to 0.775 V as listed below:

Macro-Tech 24x6 Channel 1 (2400): 83:1 ±6% or 38 dB ±0.5 dB.
Macro-Tech 24x6 Channel 2 (600): 54:1 ±6% or 35 dB ±0.5 dB.
Macro-Tech 36x12 Channel 1 (3600): 124.6:1 ±6% or 41.9 dB ±1.0 dB.
Macro-Tech 36x12 Channel 2 (1200): 64:1 ±6% or 36 dB ±0.5 dB.

Controls
Enable: A front panel pushbutton used to turn the amplifier on and off.

Level: A 31-position detented rotary potentiometer for each channel located on the front panel used to control the output level.

Sensitivity: A three-position switch located inside the PIP compartment used to select one of three input sensitivities for both channels: a sensitivity of 1.4 volts for full rated output, a fixed voltage gain of 26 dB or a sensitivity of 0.775 volts for full rated output.

Ground Lift: A two-position back panel switch used to isolate the signal ground of the phone jacks from the chassis (AC) ground.

Reset: A back panel switch for each channel used to reset the circuit breaker which protects each channel’s power supply.

Indicators
Enable: This amber indicator lights when the amplifier’s Enable switch is turned on and the low voltage power supply is operating.

Signal/IOC: Each channel has a green front panel indicator that flashes to show amplifier output. If a channel’s output waveform differs from its input by 0.05% or more, the indicator flashes brightly to show distortion. This function provides proof of distortion-free performance.

ODEP: Each channel has an amber front panel indicator that shows thermal-dynamic energy reserve. Normally, each ODEP indicator is lit to show available reserve energy. In the rare event that a channel has no reserve, its indicator will dim in proportion to ODEP limiting.

Input/Output
Input Connector: Two balanced ¼-inch phone jacks on the back panel and two balanced 3-pin female XLR connectors on the factory-installed P.I.P.-FX.

Input Impedance: Nominally 20 k ohms, balanced. Nominally 10 k ohms, unbalanced.

Input Sensitivity: Settings include 0.775 V and 1.4 V for rated output, or a fixed voltage gain of 26 dB.

Output Signal: Unbalanced, two-channel.

Output Connector: A pair of color-coded 5-way binding posts (for banana plugs, spade lugs or bare wire) for each channel. Note: Because of its higher output power, the Macro-Tech36x12 has an additional set of binding posts for Channel 1.

Output Impedance: Less than 10 milliohms in series with less than 2 microhenries.

DC Output Offset: (Shorted input) ±10 millivolts.

Protection
Macro-Tech amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature, chain destruction phenomena, input overload damage and high-frequency blowups. They also protect loudspeakers from input/output DC and turn-on/turn-off transients.

If unreasonable operating conditions occur, the patented ODEP circuitry will proportionally limit the drive level to protect the output transistor stages, particularly in the case of elevated temperature. Transformer overheating will result in a temporary shutdown of the affected channel; when it has cooled to a safe temperature, the transformer will automatically reset itself. Controlled slew-rate voltage amplifiers prevent RF burnouts. And input overload protection is provided by current-limiting resistance at the input.

Turn On: Four second turn-on delay with no dangerous transients.

Construction
Black coated steel chassis and aluminum front panel with Lexan overlay. Chassis utilizes specially designed flow-through ventilation from front to side panels.

Cooling: Internal heat diffusers with forced air cooling for rapid, uniform heat dissipation.

Dimensions: 19 inch (48.3 cm) standard rack mount (EIA Std. RS-310-B), 3.5 inch (8.9 cm) height, 16 inch (40.6 cm) depth behind mounting surface, 2.5 inch (6.35 cm) in front of mounting surface.

Weight: Center of gravity is approximately 6 inches (15 cm) behind the front mounting surface.
