M•1400/M•1400i High-Current Power Amplifier  The Mackie M•1400/M•1400i is a dual channel, high output power amplifier that incorporates a number of unique features including FR “Fast Recovery” design, high continuous-current output, built-in subwoofer crossovers, and a T-Design constant-gradient cooling tunnel for improved cooling efficiency and output device reliability.  The M•1400/M•1400i is rated at a continuous output of 250 watts per channel into 8Ω, 425 watts per channel into 4Ω and 630 watts into 2Ω. In bridge mode the M•1400/M•1400i is rated at 850 watts into 8Ω and 1260 watts into 4Ω. Variable low-cut filters on each channel, with a range from off to 170Hz, enable tighter bass response and a Constant Directivity Horn EQ improves high-frequency reproduction. The CD Horn EQ is 6 dB/octave and its “knee” position is sweepable from 2kHz to 6kHz. The built-in limiter is channel independent and helps eliminate clipping. Inputs are balanced/unbalanced 1/4" and XLR, and XLR thru connectors allow the full-range signal to be routed to another M•1400/M•1400i. Speaker connections on the M•1400 are Speakon® and binding posts, while speaker connections on the M•1400i are 1/4" and binding posts.  To effectively deal with clipping, an amplifier must be able to recover almost instantaneously. That is the definition of “Fast Recovery”. Rather than using negative feedback to help control clipping distortion, the M•1400/M•1400i employs a very sparse amount of negative feedback. The use of Baker Clamp circuits on the positive and negative voltage amp stages prevents saturation (and latching) during periods of overdrive. In addition, a transistor senses when the Baker Clamp is active and activates the internal limiting circuits. This results in no latching, instant recovery from overdriving the amp, and a superior sound.

In single-channel operation it shall deliver 850 watts RMS into 8 ohms and 1260 watts into 4 ohms, with no more than 0.05% total harmonic distortion. The power amplifier shall deliver a maximum continuous average sine wave power output at mid-band of 300 watts RMS into 8 ohms per channel, 500 watts into 4 ohms, and 700 watts into 2 ohms with both channels operating, with no more than 1% total harmonic distortion. In single-channel operation it shall deliver 1000 watts RMS into 8 ohms and 1400 watts into 4 ohms, with no more than 1% total harmonic distortion. 3. POWER SUPPLIES. All necessary operating voltages for the amplifier shall be provided by an internal power supply. A master power switch shall be located on the front panel along with a green power-indicating light. 4. INPUT CHANNEL CONNECTIONS. Each monaural input channel shall have an electronically balanced linelevel input, presenting no less than a 20k ohm impedance to the source. Each input shall have an input sensitivity of +4 dBu, requiring no more than 1.23V RMS to be driven to rated output into a 4 ohm load. The input connector shall appear on the rear panel as a female XLR-3 type connector. In addition, each monaural input channel shall have a parallel 1/4" TRS phone jack and a male XLR-3 type connector, which can be used as inputs or “thru” jacks for daisy-chaining the input signal to another amplifier. Pin 2 of the XLR connectors, and the tip of the 1/4" TRS phone jack, shall be non-inverting. 5. INPUT CHANNEL LEVEL CONTROLS. Each monaural input channel shall be equipped with a gain control appearing on the front panel, each having 20 detent positions, and calibrated in dB and volts. 6. FRONT PANEL INDICATORS.

The T-Tunnel design provides a shorter, more direct path for cool air. This allows for reduced heat build up and cooler transistor operation.  The amplifier has a subwoofer mode that allows you to turn on the built-in subwoofer crossover. When activated, the signals appearing at the left and right inputs are summed, directed to a low-pass filter, and routed to both output stages. The inputs are summed regardless of stereo, mono, or bridge amp mode selection. A switch selects the cutoff frequency of the filter at either 63Hz or 125Hz.
