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 wonder if I can attach a smallRIG handle on top ?

A: It should connect via the top cheese-plate.

Q: 2. am I able to use 3 labs with beachtech?

A: You can use up to 2 lavalier mics with the Beachtek DXA-MAX.

Q: 3. I'd like to use this with my Sony a6300 which has a 3.5 mic input, but no headphone/line out. Will I be able to monitor sound while recording? Also, will I need a line to microphone attenuation cable or does this feature mic out?

A: This audio adapter will allow you to monitor the audio before it goes out to your camera. The output level is set to MIC Level, and a 3.5mm cable is provided to connect to your camera.

Q: 4. How do I use the meters on the unit when I am likely more interested to go by the meters on the DSLR where the recoding is being made? I guess I am confused at to their role.

A: The meter display onboard the Beachtek DXA-MAX 2-Channel Active Audio Adapter for DSLR shows levels at one stage of the audio signal chain. These are useful to confirm that the signal coming into the Beachtek is adequate and not clipping before sending down the chain to the next stage in the camera for further monitoring and adjustment if needed.

Q: 5. Am I able to connect to a separate set-up of additional wireless and lav mics?

A: Ye. You may add your own wireless microphone receiver(s).

Q: 6. Is this audio adapter compatible with the Sony HXR-MC2500 Camcorder?

A: Yes, the Beachtek DXA-MAX is compatible with any camera that has a 3.5mm microphone input.

Q: 7. Does the 3.5mm input jack work with the Deity D3 Pro microphone? Does the jack provide plug-in power?

A: The Deity D3 Pro has a internal battery, it does not need the Beachtek to provide it with power. Just make sure to charge the microphone with the USB-C cable that they provide you with in the box.

Q: 8. looking to use 3 lav. to record audio for my Sony mirrorless camera. I currently have the beach tech which only records 2.?

A: The Beachtek DXA-MAX 2-Channel Active Audio Adapter for DSLR (BH #BEDXAMAX • MFR #DXA-MAX) can only record up to two microphones/channels/tracks. To record more than two lavaliers, consider a 4-track recorder such as the TASCAM DR-70D 6-Input / 4-Track Multi-Track Field Recorder with Onboard Omni Microphones (BH #TADR70D • MFR #DR-70D).

Q: 9. 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: 10. Does the battery power LED indicate when the internal battery is low by turning red or something?

A: Yes it will glow red/orange when the battery level is low.
