Styled in natural bamboo veneer, the LS1a from Grimm Audio is an active all-in-one stereo speaker system designed to combine the best aspects of a high-fidelity system with the accuracy of top-tier studio monitors for demanding musicians, engineers, producers, and audiophiles. Part of the LS1 family, the LS1a is the most moderately priced option; it does not included the LS1USB interface and scales back on a few of the most advanced features in favor of a non-magnesium woofer, a lighter foot plate, and a lacquered cabinet. It is also constructed without some of the labor intensive modifications and individual acoustic calibrations made on the LS1v2 and LS1be models.

Why choose between having accurate, professional-quality monitoring or having a high-fidelity system for audiophile listening when the LS1 series has been specifically designed to deliver both? The speaker incorporates top-quality DSP, converters, and amplifiers to completely control all the critical aspects of audio reproduction and ensure pure, ultra-accurate sound.

The LS1a possesses all these essential qualities and therefore performs at a true reference level in all key areas for artists and music lovers alike. The speaker retains the low distortion and extremely linear amplitude and phase response the LS1 series is renowned for (achieved through Computer Aided Calibration during production). In addition, the form factor makes positioning close to a wall possible without wall-reflection interference. The speaker features a DSP-controlled frequency curve and is unidirectional down to 250 Hz with a well-behaved off-axis response.

The flat, wide cabinet design lowers the baffle step frequency, allowing sound below the 250 Hz range to be radiated in all directions equally, while higher frequencies, where phase problems are more perceptible, are more forward focused. The rounded legs also help to reduce the deterioration of the stereo image, while the shallow cabinet moves the resonance along the depth axis inside the box, significantly above the crossover frequency of the 8" low-frequency driver, helping to avoid boxiness. The 1" Seas tweeter’s exceptionally low distortion in the midrange allows a fairly low crossover frequency that benefits vertical dispersion. Its small constant-directivity horn ensures an even spread of high-frequency sound.

Digital input signals are re-clocked by a state-of-the-art ASRC circuit, which is based on the same oscillator as the legendary Grimm CC1 clock. Analog inputs are first converted to digital with a high-performance A/D converter. The signal then enters the DSP, which has a datapath of 48-bit wide with a 76-bit accumulator. Each driver then has its own high-quality D/A converter. The output of the D/A converters is directly fed into 120W Hypex Ncore power amplifiers. The optional LS1s subs have an additional 400W amp each. Hypex Ncore power amplifiers have extremely low harmonic distortion and are the perfect choice for the LS1a due to their linearity and excellent transient response. Throughout the whole circuit, careful attention has been paid to component selection like capacitors and resistors. Critical parts, such as power supply regulators, are of Grimm's own discrete design.

The LS1a has versatile connections for analog and three digital AES/EBU sources. With the optional USB audio interface, any computer can become your audio source. The LS1r controller or an MU1 music player (both available separately) allow for convenient control of volume and source selection.

An LS1a covers the full-frequency range as an elegant two-way system. By adding an LS1s or even an SB1 subwoofer set, the LS1a becomes a very-low distortion, three-way loudspeaker that can handle all music styles in any size room.

Related Questions and Answers

Q: 1. I assume this would hookup to an iPAD, but my question is would it supply power to an iPAD also?

A: No

Q: 2. What else do I need to purchase to work with full face motorcycle helmets?

A: In addition to this system, Midland recommends the AVP-H2 Helmet kit.

Q: 3. Do both units support mic and headphone? Basically, is it 2-way?

A: The Wi Digital AudioStream Pro EL is 2-way as a system, but not standalone. 2-way communication is achieved when the transmitter is connected to a computer or iPad, and then you connect a headset mic with a TRRS connection into the receiver. This allows users to wirelessly connect to a device, and have the ability to send and receive audio.

Q: 4. Can you use a turntable with Antelope Satori?

A: Unfortunately the Satori is not made to take a turntable. There are no phono pres just mic and line inputs.

Q: 5. What type of frequency is used UHF or VHF?

A: The Midland LXT500VP3 uses FRS and GMRS services which operate in the UHF band.

Q: 6. How would you gauge & control levels when you attach 1 lav to the stereo jack, 1 XLR to the right, & 1 lav to the mono left?

A: You can only use a maximum of two microphones, one connected to the left channel and the other connected to the right channel, with the Beachtek DXA-MAX 2-Channel Active Audio Adapter for DSLR. However, if you are using the stereo input, we suggest not connecting any other microphones as it would create phase and/or level issues.

Q: 7. How many devices are in the box

A: This is a single device. Compatible speakers and microphones are sold separately.

Q: 8. Does this identify as 4x separate outputs (mains & monitors) in a DAW?

A: No, this will only give you the main stereo output signal in both main outs and headphones.

Q: 9. Can multiple transmitters be synced to a single receiver with the AudioStream Pro EL? I want to mic multiple speakers and have all voices blended into a single channel.

A: You can't do quite what you want yet. But Wi Digital AudioStream systems are very unique and versatile.

Q: 10. Hello, What is difference between this model and the Beachtek DXA-MAX 2-Channel Active Audio Adapter for DSLR?

A: This item is the Beachtek DXA-MAX 2-Channel Active Audio Adapter for DSLR.
