The Technics Panasonic SA-HE70 AV Control Receiver technical specifications:

1. **Power Output:** The power output, measured in watts per channel (WPC), indicates how much power the receiver can deliver to connected speakers. For example, the SA-HE70 might output around 70 watts per channel into 8 ohms.

2. **Channels:** Specifies the number of channels supported by the receiver. For instance, the SA-HE70 might be a 6-channel receiver, supporting configurations like 5.1 surround sound.

3. **Audio Decoding:** Lists the audio decoding formats supported by the receiver, such as Dolby Digital, DTS, and possibly other formats like Dolby Pro Logic II.

4. **Video Processing:** Describes the video processing capabilities of the receiver, including features like upscaling, pass-through of various video resolutions, and support for different video connections (e.g., HDMI, component, composite).

5. **Input and Output Connections:** Specifies the types and number of input and output connections available on the receiver, such as HDMI, optical, coaxial, RCA, etc. This includes both audio and video connections.

6. **Frequency Response:** Indicates the range of frequencies over which the receiver can accurately reproduce sound. It's typically expressed as a range (e.g., 20 Hz - 20 kHz) along with any attenuation tolerances.

7. **Signal-to-Noise Ratio (SNR):** Measures the ratio of the desired signal to background noise, typically expressed in decibels (dB). A higher SNR indicates better performance with less audible noise.

8. **Total Harmonic Distortion (THD):** Measures the amount of harmonic distortion present in the receiver's output signal compared to the input signal. Lower THD values indicate cleaner amplification.

9. **Remote Control:** Describes the features and functionality of the included remote control, such as the ability to control various audio and video settings, switch between inputs, and adjust volume levels.

10. **Dimensions and Weight:** Provides physical dimensions and weight of the receiver, which are important for determining placement and compatibility with existing home theater setups.
