General
- Product Name: Integrated Amplifier
- Brand: Yamaha
- Model Number: A-U671
Audio
- Total Power Handling: 140 watts (How much amplifier (amplified) power (wattage) that can be handled before damaging the product.)
- Minimum Frequency Response: 10 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Total Harmonic Distortion: 0.05 percent (Measurement of the harmonic sound distortion. The lower the percentage, the cleaner the sound.)
- Maximum Frequency Response: 40 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Amplifier Class: A (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Signal-to-Noise Ratio (SNR): 95 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
- Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
Inputs
- Line-Level Inputs: true (Also referred to as low-level inputs. Enables the amplifier to receive a sound signal from another device via RCA cables.)
Features
- Bridgeable: false (Bridging an amplifier increases the power it supplies to the speaker(s).)
