大小与SR 32.4一样
Onyx 24.4 和32.4 调音台是Mackie 老牌模拟调音台SR24.4 和32.4 的升级产品。同样保留了24- 和 32- 输入通道两个型号；在话放、电路结构、Perkins EQ 等设计上做了重大提升；同时增加了内置可分配的立体声压缩/ 限幅器部分；采用100mm Panasonic 推子。极大提升了系统的适用性和性价比。
全新设计体现一流音质
积15 年模拟调音台生产经验, 凝聚一流设计团队, Mackie 倾力打造出Onyx4-Bus 系列。从电子元件和集成电路芯片的选择, 到机械构件的设计, 全部体现高标准的要求。各级电路之间采用平衡式级连, 极大提高了信噪比和整体电声性能, 具有在同类产品中超乎寻常的音质表现。值得一提的还有:Onyx 4-Bus 系列采用了Onyx 话筒前置放大器、Perkins EQ 电路和全新THAT Corporation 4301可分配的立体声压缩/ 限幅器。总之，全新的理念，全新的产品，用户尽可在这一新型系列上自由挥洒。
Onyx 话筒前置放大器
原来的SR 系列采用的是在同类产品中领先的XDR 话筒前置放大器, 新型Onyx4-Bus 系列则进一步提升采用Onyx 话筒前置放大器, 音质更纯净, 具有更高的保真度和射频抑制比(RFI)、更大的输入信号余量、更宽的动态范围。例如, 技术指标可达到:123dB 动态范围;-129.5dBm 等效输入噪声;0.0007% 总谐波失真...... 时间和实践已经向业内证实了Onyx 前置话筒放大器的卓越性能。
Perkins EQ:“ 英国式均衡”之声, 滤波控制更强大
由资深音频设计师Cal Perkins( 和Greg Mackie 先生一起, 开创Mackie产品鼻祖的一流设计大师) 主持设计的Onyx EQ 电路—— Perkins EQ, 采用经典的 Wein 电桥振荡电路, 具有更大的滤波和相位调节功能, 再现六、七十年代风靡全球的英国式调音台之声。Perkins EQ 设计为 具有扫描式中低频和中高频的4- 段式均衡,—非常适合现场扩声。
内置可分配式立体声压缩/ 限幅器
音响工程师在现场混音处理时经常要用到压缩/ 限幅器, 以在各种信号电平情况下保证平滑、自然的音质效果。鉴于这样的原因, 我们在Onyx 24.4和 32.4. 系统中集成了一组高质量的THAT Corporation 立体声压缩/ 限幅器, 提供真正的RMS 检波和根据音乐频谱特性设计的精确自动增益控制。该压缩/ 限幅器还具有独立的噪声门、压缩比及快/ 慢起控控制, 可以分配至左/ 右路主输出推子后( 用于系统限幅和保护) 或编组1 / 2 或编组3 / 4输出推子前( 用于对编组信号进行压缩处理, 例如打击乐或背景声), 这些功能都是现场扩声处理中最实用的。

How do you improve upon a hugely successful mixer? With a heavy dose of R&D, that's how. Building on the success of the legendary SR32·4, Mackie is proud to introduce the new Onyx 32.4 32-channel / 4-bus live sound console. Retaining the same convenient footprint as its predecessor, the ultra state-of-the-art Onyx 32.4 brings dozens of new features and enhancements to the party: 100mm Panasonic? faders, premium Onyx mic preamps, completely redesigned analog circuitry with more headroom, greater routing flexibility, new Perkins EQ, and a built-in assignable stereo compressor/limiter. And we're barely scratching the surface.
BETTER SOUND BY DESIGN
The Mackie Onyx 32.4 sounds noticeably better than any comparably-priced 32-channel mixer on the market today. And with good reason. The difference starts with premium Onyx mic preamps on every channel (click here for an interactive tour of the Channel strip), which offer greater dynamic range and transparency versus any other mixer mic preamp on the market. Newly designed 4-band Perkins EQ offers the sweet, musical sound of the legendary British consoles of yesteryear, yet with greater filter control. And while the 32.4 is not the first mid-format console to offer an onboard compressor/limiter, we specified a THAT? Corporation 4301 assignable stereo compressor/limiter, and then had it custom tailored specifically for the Onyx 4-bus Series. Finally, overall mixer sound quality and headroom has also been raised, thanks to the use of premium components, completely redesigned summing bus circuitry, and an electronically balanced design throughout the entire signal chain. Taken together, the Onyx 32.4 gives you big, full-range sound and even lower noise than esoteric mixing consoles costing much more.
ONYX MIC PREAMPS: AFFORDABLE "BOUTIQUE" QUALITY
Although our highly-acclaimed XDR mic preamps set high standards for quality and performance, Onyx mic preamps offer even greater fidelity, headroom and transparency—as well as better radio frequency (RFI) rejection and wider dynamic range than ever before. Numerous magazine and online reviews have confirmed Onyx preamps sound just as good as many "boutique" standalone mic pres—with specs like 123dB total dynamic range, -129.5 dBm Equivalent Input Noise, and 0.0007% Total Harmonic Distortion. Click here to learn more about Onyx mic pres. Read more.
PERKINS EQ: SWEET "BRITISH" CONSOLE SOUND, ONLY BETTER
We called on veteran audio engineer Cal Perkins to develop the EQ circuitry for the Onyx Series, and in turn Cal designed an extremely effective and musical 4-band EQ, with sweepable low- and high-mids—perfect for live sound mixing. Called the Perkins EQ, Cal's new circuitry builds on the classic Wein Bridge circuit used in the British mixing desks of the '60s and '70s, providing greater filter and phase shift control. Perkins EQ offers more control over harmonic content than any other EQ on the market, and it's only available on Mackie products. Read more.
ASSIGNABLE ONBOARD STEREO COMPRESSOR/LIMITER SECTION
Compression is an indispensable tool in a sound engineer's arsenal. That's why we integrated a high-quality master compressor/limiter chip from THAT? Corporation into the Onyx 32.4. This assignable analog stereo compressor/limiter was designed and manufactured in the US by veteran analog engineers, offering true RMS Detection and Auto Make-up Gain for extremely accurate and musical results. Controls are provided for Threshold, Ratio and Fast/Slow Attack, and the compressor can be assigned post-fader to the L/R main mix (for system limiting and speaker protection) or pre-fader to Group 1/2 or 3/4 outputs (for grouped signal compression, like drums or background vocals). This reduces the need for separate outboard processing.
MASTER SECTION
If total control over signal routing, talkback/monitor mixing, and external effects processing is what you seek, then look no further—the Onyx 4-Bus Series Master section has everything you've come to expect from a Mackie mixing console, and more. The onboard 6 x 2 Matrix Mixer is the solution to the “not-enough monitor send” blues. Not only can you use the Aux Sends to generate up to six monitor mixes, but the Matrix Mixer can be used to generate two additional independent mixes—ideal for IEM (in-ear-monitor) systems, cry rooms, green rooms or other zoned outputs. Visual monitoring of Solo, Main output and compression/limiting is expertly handled via four, giant 12-segment LED ladders. And even the Sub Groups feature 4-segment LEDs, so you know what signal levels are at glance. Click here for a guided tour to the Master section.
BALANCED MIC/LINE DIRECT OUTPUTS
If you plan to use the Onyx 32.4 for live recording, we've included another invaluable feature: convenient balanced Mic/Line direct outputs for every channel. No longer will you need to run a splitter, or take inpidual direct outs from the board to your tape or hard disk recorder. Thanks to four DB-25 female connectors on the rear of the console (configured with standard Tascam? pin outs), you can quickly route all mic/line signals to an external device. All of these balanced direct outs are pre-fader and switchable via internal jumpers as either pre- or post-EQ. So there are only four cables between the Onyx 32.4 and your recorder—it just doesn't get any easier than this.
BUILT MACKIE TOUGH
Because we at Mackie know how tough the road can be on equipment, we designed the Onyx 4-Bus Series to handle almost anything you can throw at it. Vertical aluminum supports are placed strategically to maximize the structural integrity of the solid-steel chassis. And because these boards get moved around a lot, we designed comfortable carry handles right into the sides—even though they are portable enough to just tuck them under your arm and go.
Designed with a practical and easy to understand layout, anyone from a Sunday morning volunteer operator to a seasoned professional engineer can quickly learn to operate the Onyx 32.4 console. This makes it perfect for a wide range of live applications including churches, small- to medium-sized clubs, touring bands, and rehearsal facilities, just to name a few. With stunning sound quality and renowned Mackie engineering—combined in a full-featured, portable, highly affordable, mid-format mixing console—the Onyx 32.4 is destined to set the new standard.
