Pairing
Can be perfectly paired with the E70, E70 Velvet and L70 to instantly unlock a more comprehensive system of high quality music experiences, from digital sources to speakers and headphones
Features
- THD+N: <0.0004%
- Inputs: XLR/TRS/RCA
- Fully balanced
- High SNR and DNR Performance
- Bypass Volume Control Function
- 12V Trigger Input for Seamless Integration
- Combo Connectors (Compatible with XLR and TRS) and RCA Connectors
Impressive Output Power in a Compact Package
Despite their small size, the PA7 series amplifiers pack a punch, delivering 210W x 2 (PA7) or 300W x 2 (PA7 Plus) to a 4-ohm load at 10% distortion. With a 1% distortion standard, the output is 200W x 2 (PA7) or 245W x 2 (PA7 Plus) for a 4-ohm load. These power outputs and low distortion levels are more than enough for most speakers and applications.
Multiple Input Options
The PA7 and PA7 Plus offer two sets of input connectors: Combo connectors (compatible with XLR and TRS) and RCA connectors, ensuring compatibility with a variety of audio sources.
Stack ‘Em Up
Pair the PA7 or PA7 Plus with the E70, E70 Velvet, and L70 for a comprehensive high-quality music system, utilizing XLR, TRS balanced, or RCA cables for signal transmission. Control the volume on the amplifiers or bypass their volume control to use a dedicated pre-amplifier.
12V Trigger Input for Seamless Integration
Both the PA7 and PA7 Plus feature a 12V Trigger input interface, allowing you to connect them with other devices for synchronized on/off switching.
