Mackie FR M.1400, FR M.1400i Specifications

M•1400/M•1400i
M•1400/M•1400i
The Mackie M1400/M•1400i is a dual channel, high
output power amplier 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 efciency and output device reliability.
The M1400/M•1400i is rated at a continuous out-
put of 250 watts per channel into 8Ω, 425 watts per channel into 4Ω and 630 watts into 2Ω. In bridge mode the M1400/M•1400i is rated at 850 watts into 8Ω and 1260 watts into 4Ω. Variable low-cut lters 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 M1400/M•1400i. Speaker connections on the M1400 are Speakon® and binding posts, while speaker connec­tions on the M1400i are 1/4" and binding posts.
To effectively deal with clipping, an amplier must
be able to recover almost instantaneously. That is the denition 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.

Architects’ and Engineers’ Specications
1. GENERAL. The amplier shall have a free-standing
frame with front and rear brackets for rack-mounting, and supplied with four resilient feet suitable for table­top placement. The amplier shall be capable of two­channel operation, with a switch to place the amplier into single-channel operation by bridging the outputs of the two channels.
2. POWER OUTPUT. The two-channel power ampli-
er shall deliver a rated continuous average sine wave power output over a 20Hz to 20kHz bandwidth of 250 watts RMS into 8 ohms per channel, 425 watts into 4 ohms, and 630 watts into 2 ohms with both channels operating, with no more than 0.05% total harmonic dis­tortion. 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 amplier 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.
ages for the amplier 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 amplier. 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 mon-
aural 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. Each channel shall
have an associated six-segment LED meter appearing on the front panel, capable of displaying signal present, –20 dB, –9 dB, –6 dB, –3 dB, and overload. Each chan­nel shall have internal status LEDs appearing on the front
All necessary operating volt-
High-Current Power Amplifer
panel to indicate activation of protect mode and short-cir­cuit protection. Two temperature status LEDs shall appear on the front panel, one to indicate normal operation (COLD) and one to indicate thermal protection (HOT).
7. PROTECTION FEATURES. The amplier shall pro-
vide delayed activation of the outputs at turn-on. Each channel shall have a short-circuit protection circuit for detecting excessive current ow at the output that, when activated, mutes the output for four seconds. The short­circuit protection shall continuously cycle on and off until the shorted condition is remedied. The amplier shall have a thermal protection circuit to protect the power devices from over-temperature operation. The circuit shall activate when the internal temperature crosses the safe­operating threshold and, when activated, mute the out­puts until the internal temperature cools to a safe-operat­ing temperature, at which time amplier shall resume normal operation. The amplier shall have a fan to cool the heat-producing internal components, drawing cool air in from the front, and exhausting warm air out through both sides. The fan shall operate at two speeds, the speed being determined by the internal temperature and the signal level present at the output. The amplier shall have an SCR crowbar circuit to protect the speakers against a catastrophic amplier failure. The circuit shall activate in the presence of continuous DC at the speaker outputs, and shall shut the amplier down by turning off the high-voltage rails.
8. OUTPUT CONNECTIONS. M•1400i: Each channel
shall have a heavy-duty 5-way binding post speaker out­put connector appearing on the rear panel, with 3/4" spacing for accommodating standard double banana plugs as well as spade lugs or bare wires. Each channel shall have a 1/4" TS phone speaker output jack appearing on the rear panel in parallel with the binding post.
M•1400: Each channel shall have a heavy-duty 5-way binding post speaker output connector appearing on the rear panel, with 3/4" spacing for accommodating stan­dard double banana plugs (120V versions only) as well as spade lugs or bare wires. Each channel shall have a Neutrik brand Speakon® speaker output jack appearing on the rear panel in parallel with the binding post output.
9. AMP MODES. The amplier shall have a three-way
switch appearing on the rear panel for selecting the mode of operation, which shall include stereo (two channels in, two channels out), mono (one channel in, two chan­nels out), and bridge (one channel in, one channel out, bridged between both speaker outputs).
10. OUTPUT APPLICATIONS. The amplier shall
have a three-way switch appearing on the rear panel for

selecting limiter on, limiter off, and subwoofer mode. The defeatable electronic limiter circuit shall sense the onset of clipping and shall limit the input signal and thereby prevent the output from clipping. The amplier shall have a two-way switch appearing on the rear panel for select­ing between a 63Hz and 125Hz low-pass cutoff frequency when subwoofer mode is selected.
11. LOW-CUT FILTER. Each channel shall have a low-
cut lter with a variable frequency control appearing on the rear panel covering a range of 10Hz (OFF) to 170Hz.
12. CONSTANT DIRECTIVITY HORN EQ. Each chan-
nel shall have a two-way switch appearing on the rear panel for selecting a constant directivity horn equaliza­tion circuit. When selected, this circuit shall provide a
6 dB per octave high-frequency boost. The EQ shall have a variable frequency control appearing on the rear panel covering a range of 2kHz to 6kHz. The 6kHz position shall be called AIR.
13. PHYSICAL CONFIGURATION. The amplier
shall be rack-mountable with rear support rails for extra support, and shall have a steel chassis frame painted gray-black. The amplier shall be 19" wide (483mm), 3.5" (2U) tall (89mm), and 15.25" deep (387mm), and shall weigh 36 pounds (16.3 kg).
14. DESIGNATION. The power ampliers shall be
a Mackie M1400 and M1400i.

The M1400/1400i uses a unique T-Design
constant-gradient cooling tunnel that draws air in through the front of the amplier and forces it out through the amplier’s sides. 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 amplier has a subwoofer mode that allows
you to turn on the built-in subwoofer crossover. When activated, the signals appearing at the left
M•1400/M•1400i
and right inputs are summed, directed to a low-pass lter, 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 lter at either 63Hz or 125Hz.
