Frequently Asked Questions:
How does the Sigma DM-15+'s onboard tuner and digital chromatic tuner contribute to its overall functionality as an acoustic guitar amplifier?
The Sigma DM-15+'s onboard tuner and digital chromatic tuner are essential features that enhance its overall functionality as an acoustic guitar amplifier. With the built-in tuner, players can quickly and easily tune their guitars without having to carry around a separate tuning device. This is particularly useful in live performances or studio settings where time is of the essence. The digital chromatic tuner allows for precise and accurate tuning, making it easy to achieve the perfect pitch every time. Overall, these features contribute significantly to the DM-15+'s versatility and practicality as an acoustic guitar amplifier.
"How does the Sigma DM-15+ differ from traditional acoustic guitars in terms of pickup and amplification technology?"
The Sigma DM-15+ electric-acoustic guitar by Yamaha is a unique instrument that combines the warmth and richness of an acoustic sound with the versatility and control of an electric guitar. Unlike traditional acoustic guitars, the Sigma DM-15+ features built-in pickup and amplification technology, which allows for direct connection to an amplifier or PA system without the need for a separate microphone or external preamp. The Sigma DM-15+ uses a specialized transducer system to capture the natural sound of the guitar's body and strings, which is then amplified and processed through an onboard preamp and equalizer. This technology provides exceptional tonal accuracy and clarity, as well as greater control over the guitar's volume, tone, and resonance. Compared to traditional acoustic guitars, which rely solely on their inherent acoustics and may require a separate microphone or DI box for amplification, the Sigma DM-15+ offers several key advantages:
1. Direct connection: The built-in pickup system allows for direct connection to an amplifier or PA system, without the need for a separate microphone or external preamp. This simplifies setup and reduces the risk of feedback or interference. Greater tonal accuracy: By using a specialized transducer system to capture the natural sound of the guitar's body and strings, the Sigma DM-15+ provides exceptional tonal accuracy and clarity, even at high volumes. Enhanced control: The onboard preamp and equalizer offer greater control over the guitar's volume, tone, and resonance, allowing for more precise adjustment to suit different playing styles and venues. Versatility: The electric-acoustic design of the Sigma DM-15+ allows for a wider range of playing styles and techniques, from fingerpicking and strumming to lead guitar work, than is possible with traditional acoustic guitars alone.
What is the precise method for calibrating the high-pass filter on a Sigma DM-15+ digital multimeter to accurately measure the acoustic guitar's piezoelectric pickup impedance?
1. Connect your piezoelectric pickup to the multimeter's input, ensuring the correct polarity. Set the multimeter to measure impedance (Z) in ohms. Choose a suitable frequency range for calibration. For most acoustic guitar pickups, this is around 100 Hz to 10 kHz. Use an external signal source, such as a function generator or a sine wave oscillator, to provide a calibrated AC voltage at the desired frequency. Set the multimeter's high-pass filter cutoff frequency (CFC) to its maximum value, typically above 20 kHz. This will disable the high-pass filter and allow you to measure the pickup's impedance without filtering. Measure the pickup's impedance using the signal source from step 4. Take note of this value as your reference point. Gradually decrease the CFC frequency in small increments (e. Hz) while re-measuring the pickup's impedance at each step. Identify the CFC frequency that results in a measured impedance closest to the reference value obtained in step 6. This is likely the optimal high-pass filter cutoff frequency for your specific pickup and application. Verify the calibration by measuring the pickup's impedance with the CFC frequency set to the newly determined value, using both the signal source from step 4 and an actual acoustic guitar signal. It's worth noting that some pickups may have a resonant peak or dip in their impedance curve due to their design or construction. In such cases, the optimal high-pass filter cutoff frequency might need to be adjusted based on the specific characteristics of your pickup.
What specific adjustments can be made to the tone and resonance of a Sigma DM-15+ acoustic guitar using its built-in active electronics system?
1. Bass Roll-off:** The active electronics system features a bass roll-off control that allows you to adjust the low-end response of the guitar. Turning this control clockwise will reduce the amount of low-frequency energy present in the signal, resulting in a brighter, more trebly sound. Counterclockwise will increase the low-end presence, adding warmth and depth to the tone. Mid-Boost:** The mid-boost control allows you to enhance or attenuate the midrange frequencies (typically between 200 Hz and 500 Hz). Turning this control clockwise will emphasize the midrange, resulting in a more pronounced presence and clarity in the sound. Counterclockwise will reduce the midrange emphasis, creating a smoother, less forward sound. Treble Boost:** The treble boost control allows you to adjust the high-frequency response of the guitar. Turning this control clockwise will increase the amount of high-end energy present in the signal, resulting in a brighter, more aggressive sound. Counterclockwise will reduce the high-end presence, creating a warmer, less edgy tone. Resonance:** The resonance control allows you to adjust the amount of feedback and sustain produced by the guitar's electronics system. Turning this control clockwise will increase the amount of feedback and sustain, resulting in a more resonant and articulate sound. Counterclockwise will reduce the amount of feedback and sustain, creating a drier, less resonant tone. In terms of specific tonal adjustments, here are some general guidelines:
* For a brighter, more aggressive sound, try:
+ Bass roll-off: 12 o'clock to 3 o'clock
+ Mid-boost: 9 o'clock to 12 o'clock
+ Treble boost: 3 o'clock to 6 o'clock
+ Resonance: 9 o'clock to 12 o'clock
* For a warmer, more balanced sound, try:
+ Bass roll-off: 3 o'clock to 6 o'clock
+ Mid-boost: 3 o'clock to 6 o'clock
+ Treble boost: 6 o'clock to 9 o'clock
+ Resonance: 6 o'clock to 9 o'clock
Keep in mind that these are general guidelines, and the best settings for your guitar will depend on your personal playing style and musical preferences. Experiment with different combinations of settings to find the tone and resonance that works best for you.

The Sigma DM-15+ is a remarkable acoustic guitar, setting itself apart from other popular models through its innovative features and high-quality craftsmanship. This instrument boasts a solid cedar top with mahogany back and sides, providing a rich, warm tone that resonates with both beginners and seasoned musicians alike.
One of the key technical aspects that makes the Sigma DM-15+ unique is its built-in microphone system. Unlike traditional acoustic guitars, this feature allows for amplification without compromising the natural sound of the instrument. This is especially useful for live performances or recording sessions where a larger volume is required.
Additionally, the Sigma DM-15+ has an adjustable truss rod that ensures proper neck alignment and prevents warping over time. The rosewood bridge and fingerboard add to its luxurious feel, while the open-gear tuners offer precise tuning adjustments.
Compared to other popular acoustic guitars such as the Yamaha FG800 or the Taylor 114ce, the Sigma DM-15+ stands out due to its unique blend of traditional craftsmanship and modern technology.
