Emb Pro 700-watt Digital Rack Mountable Karaoke Mixer Stereo Amplifier EBK37B...

The EMB Pro EBK37BT is a rack-mountable stereo karaoke mixer amplifier made to combine vocal microphones with music playback in one component. It is designed for home karaoke rooms, parties, small venues, and installed entertainment systems using passive speakers. Its rated 700-watt peak output provides amplification while its onboard mixer controls help balance music and vocal sources.

Two front-panel microphone inputs let two performers connect at the same time for duets, hosting, or announcements. Each microphone channel has separate level, balance, echo, low, mid, and high controls, plus a -10 dB pad. This arrangement allows vocal sound to be adjusted independently before it is blended with the music program.

The EBK37BT supports Bluetooth streaming and USB playback for compatible digital music sources. It also includes RCA connections for VCD and DVD audio sources, allowing it to work with traditional karaoke players and other analog playback equipment. An input selector switches among USB, Bluetooth, VCD, and DVD sources.

Vocal processing is built around adjustable echo controls, including echo level, low and high tone adjustment, repeat, delay, and stereo/mono selection. Separate music controls provide volume, balance, and three-band low, mid, and high adjustment. A pitch control is also provided for music playback adjustment.

For system integration, the EBK37BT uses rear speaker binding posts for passive speakers and includes multiple RCA signal connections. Mic, record, and line outputs support expansion to compatible equipment, while the effects loop can accommodate an external processor or equalizer. Its rack-mountable format and included remote control make it suited to permanent karaoke systems as well as portable event racks.

Design & Installation

The EBK37BT has a rack-mountable chassis with side mounting wings and a control-focused front panel. Front-panel controls include microphone, echo, music, and master-volume adjustments, along with a USB port and microphone jacks. The published product information does not specify the chassis material or rack-unit height.

Connect compatible passive speakers to the rear binding-post terminals, observing correct polarity, and connect music devices through Bluetooth, USB, or the appropriate RCA inputs. Leave ventilation openings clear when placing the unit in a rack, and set the rear voltage selector correctly for the local power system before use. For an expanded setup, use the RCA line, record, microphone, or effects-loop connections with compatible external equipment.
