Two-Way Speaker Design: The Mackie SRM450v3 powered
loudspeaker features a two-way driver design with a 1.4" titanium dome
compression tweeter and 12" high-output woofer. A precision 2-way crossover
splits the high and low frequencies between the tweeter and woofer.
1000W Peak Power: The Mackie SRM450v3 employs an
ultra-efficient Class-D amplifier (400W RMS/800W Peak) to drive the woofer for
dynamic low frequency response at all volume levels. It also features a
traditional Class AB power amplifier (100W RMS/200W Peak) to drive the tweeter
for clear high frequency performance.
Application Specific Speaker Modes: The Mackie SRM450v3 lets you
choose between four different speakers modes to optimize the speaker for your
type of application.
- PA: This mode is full-range, but focuses on midrange clarity
where vocal often reside; great for most sound reinforcement applications.
- DJ: This mode boosts the lows and highs with a mild tuck to the
mids; perfect for music playback.
- Monitor: This mode features a low frequency roll-off and a
reduction around 2kHz to ensure maximum gain before feedback in monitor
- Solo: This mode features a low frequency roll-off to get rid of
unwanted thumps and adds boost and sparkle to midrange and high frequencies;
perfect for sign-songwriters.
Automatic Feedback Destroyer: The SRM450v3's Automatic Feedback Destroyer
feature gets rid of nasty feed with a single button push. You get instant
assessment and correction of feedback with up to four incredibly narrow 1/16th
Gain Knobs: The gain knobs (1-2) adjust the input sensitivity of the
mic, line, and/or RCA inputs. This allows signal from your connected external
source to be adjusted to run through each channel at optimal operating levels.
2 Wide-Z Inputs: Both channels (1-2) feature Wide-Z inputs with
combo jacks that may accept balance/unbalanced XLR and 1/4" TR/TRS connections.
The gain range of the Wide-Z inputs may handle anything from an instrument or
mic level to a line-level signal such as from a mixer.
Stereo RCA Input: The stereo unbalanced RCA inputs allow you to play a
CD player, portable audio player, or other line-level audio source through the
Mackie SRM450v3 loudspeaker.
XLR Thru Output: This male XLR-type connector produces exactly the
same signal that is connected to the main input jack (1) or a mix of channels
1-2. Use it to daisy-change several SRMv3 series loudspeakers together of the
same signal source(s).
Smart Protect DSP: Mackie Smart Protect DSP provides
intelligent system protection to safeguard the powered loudspeaker and ensure
long life, plus great sound every time. Mackie's Smart Protect DSP includes the
following protection circuits.
- Limiter: Each driver has its own transparent
compression circuit, which helps protect them from damaging transient peaks.
- Over-Excursion : An 18 dB/octave high-pass filter, inserted just
before the low frequency amplifier, protects the woofer from bottoming-out
when the low-end is driven to the maximum.
- Thermal: Separate thermal switches activate and shut down the
high and/or low frequency amplifiers until they cool down.
Impact-Resistance, Portable Enclosure: The cabinet is
constructed of high-pressure injected polypropylene. The enclosure features
reinforcement ribbing and structural strengthening resulting in a strong,
super-rigid design provide ideal acoustical characteristics.
Mounting Options: There is an integrated pole mount cup for
use with an optional pole mount system (sold separately). The trapezoidal
cabinet has also been designed to provide an ideal floor monitor position. In
addition, the speaker is fitted with suspension points to hang the speaker in
