The Dynavox ESA-18 MK BT is the successor of the E-SA18 stereo mini amplifier, which has been successful for many years. Compared to its predecessor, the device has a completely revised solid metal housing with a massive 4mm front plate, slightly changed dimensions and BT reception. The Dynavox ESA-18 MK BT has 2 line and a microphone input. The microphone input can be adjusted in volume and echo. Switchable loudness, record out, separate treble and bass regulation as well as a switchable auto-standby control (device switches off automatically after approx. 30 minutes without signal output) complete the extensive equipment.This text is machine translated.
