The Model 2950 Channel One With 24/96 Analog to Digital Converter Module 2376 from SPL is a single channel strip which includes a number of powerful onboard tools for corrective and creative sound design when recording voices, instruments, and other or analog or digital sources (with optional A/D module). The unit e is built in the tradition of earlier SPL channel strips: the Frontliner, the original Channel One, and the Track One with an updated faceplate design. The device accepts three separate inputs: a balanced XLR-3F microphone input with selectable +48V phantom power, 180&Deg; phase reverse, and 50 Hz subsonic filtering; a 1/4" TRS low impedance line input with a precise balancing stage for connecting to studio grade equipment; and a low-noise high-impedance instrument input that can be easily accessed from the front panel.

The preamplifier stage of the processor features a transistor/12AX7-LPS tube design with a range from +8 dB to +68 dB of mic gain. The line signal gain range reaches from -12 dB to +22 dB, and instrument signals can be amplified between +48 dB and +39 dB.

The first processing module in the signal chain is a De-Esser which allows you to use a single knob for subtle and effective reduction of sibilants in the outgoing signal. The processor uses phase cancellation with the original signal which employ filters that only reduce s-frequencies without interfering with the remainder of the audio spectrum. An integrated auto threshold function allows the processing to occur independently of the input level, even at varying distances from the microphone.

A switchable insert send and return loop button allows for the use of external equipment for effects such as delay or reverb. The presence of the insert loop expands the flexibility of the device to an even wider range of recording applications.

The next processor in the signal chain is a compressor/limiter/noise gate module with a dedicated limit switch, a soft knee compression control knob with a maximum ratio of 1:2.5, a make up gain knob from 0 to +22 dB, and a noise gate that can operate over the signal's complete dynamic range.

The compressor module is followed by a three band EQ and FET distortion module that can be switched to operate before or after the compressor. A low mid frequency control covers a range form 30 to 700 H, a LMF-/+ knob determines the amount of boost or cut at the selected frequency between ±14 dB. Similarly, a mid/high frequency filter can be set between 680 and 15,000 Hz with a controllable gain or boost at this Q frequency within ±12 dB. An AIR Band module uses a coil-capacitor-filter with a center frequency of 17,500 Hz and a maximum possible accentuation of +10 dB or a maximum dampening of -10 dB. The FET distortion allows you to add distortion from 0% up to distinctly perceptible harmonics.

The next module provides an output gain control from -20 dB to +5.5 dB. A mute switch allows you to mute the output signal.

The final two controls include a playback control that regulates the volume of the playback signal that is passed to a musician who is monitoring with the included front panel 1/4" TRS stereo phono jack as well as a volume control for setting the volume of the microphone, instrument, or line signal.

For visual feedback the unit includes LED metering for s-detect, clip, signal presence, tube warm up, gain reduction, and PPM output. The unit can be modified with the installation of Lundahl I/O transformers.

The low-impedance Line input has a balancing stage for connecting studio equipment
The low-noise, high-impedance instrument input is accessible on the front panel

Subtly removes offending sibilants by eliminating only the "S" sounding frequencies with phase-cancelling processing technology. The unit's auto-threshold assists in constant processing even with varying microphone distances

Allows for insertion of external processors or can be used to record the pure preamplifier signal

Operates in a way such that even reverberation are recognized and not cut off

Provides an EQ design optimized to process vocals, acoustic and electronic instruments.
Low, Mid Hi, and Air-Bands allow for both corrective adjustments and/or effective sound designing processing

Applies distortion to signals

Provides an individual mix for the singer or speaker without the latency problems often associated with digital systems

The Analog/Digital Converter Module 1090 is the digital output section of the Channel 1 with a plug-and-play design for easy installation. It offers an S/P-DIF output with both coaxial and optical connectors in parallel. The heart of the module is a 24-bit converter with a variable sample rate of up to 192 kHz. Quartz oscillators help ensure a clean, low-jitter master clock signal. The internal sample rate can be switched between 44.1, 48, 88.2 and 96 kHz. Other sample rates (32, 176,4 and 192 kHz) can be set by external synchronization. The converter can be synced to other digital devices via a S/PDIF input.

The internal oscillators are automatically disabled when an external clock signal is present to prevent interference. An extremely effective voltage stabilizing circuit ensures that the converter continuously receives sufficient and stable voltage - an important prerequisite for clean, transparent audio. The compact design minimizes the signal path to the converter. Grounding surfaces on both sides of the circuit board effectively reduce interference and ensure optimal separation between analog and digital components.

Related Questions and Answers

Q: 1. Does this mixer provide a multi-track USB output, or is the USB output just a stereo mixdown?

A: The USB output is stereo only.

Q: 2. does this board offer compression for each line in?

A: Unfortunately not, the Mackie Onyx24 24-Channel Premium Analog Mixer with Multitrack USB does not offer dedicated compression for each line in channel.

Q: 3. How can we use 4 speakers from the L&R main outs for our school auditorium? We currently use two powered PA speakers with the mixer, but we need two more PA speakers.

A: Your two existing speakers will most likely have a line output or "thru" connection on the back that will allow you to connect the output from one speaker to the input on an additional powered speaker. So you can easily expand your existing setup by daisy-chaining more speakers on the left and right sides. As long as you are connecting powered speakers, you can daisy chain as many speakers as desired.

Q: 4. made from where?

A: According to the information in our system, provided to us by Yamaha, at this time the MGP24X is manufactured in China.

Q: 5. Does Mackie have a multitrack application for Mac/PC?

A: Yes the Mackie Onyx24 will do that via USB.

Q: 6. Is the zone 96 compatible with redkordbox dj?

A: Rekordbox DJ is officially compatible with specific Pioneer units only, but it may run on this mixer. It is not mapped out for the software and there may be some quirks.

Q: 7. is this outboard gear compatible with protools?

A: The mixer has a USB input/output interface. Assuming that your PC is running Pro Tools and that this program accepts input via the USB port on your computer, then it should be compatible. Also, the mixer comes with a free download of Cakewalk's Sonar LE, which performs a similar function. I would recommend that you test Pro Tools to make sure it can use the USB interface first.

Q: 8. hi! how do I lower the sound from the computer through the usb on the mixer to use the mic with low music and high mic volume?

A: Hello, Thank you for contacting Samson Technologies. We would like to assist you better and learn what configuration you are looking to accomplish. Please email us at info@samsontech.com and we can assist you through some different options. If you have any other questions or inquiries, please let me know at any time. Best Regards, James
