Wireless amplifier all-in-one speaker with CD/SD/USB/Bluetooth! Certified with technical standards mark.

Due to its high output of up to 120W, it is used for lectures, meetings, and school events (sports days, cultural festivals, clubs). Additionally, it is equipped with casters, making it easy for anyone to move. It can also wirelessly output simultaneously to other companies' audio equipment (existing facility audio, microphone connection issues, or speakers that can no longer use audio functions). Of course, it can also operate simultaneously with OKAYO (GPA series, JL series, JDL series). This product complies with the technical standards certification specified by the Radio Law. Using equipment without the technical conformity mark may violate the Radio Law, so please be cautious about purchasing unapproved devices or using equipment that complies with the old spurious emission standards. Sales Start: GPA-828 (800MHz analog band) from July 2017 JDL-710 (800MHz digital band) from September 2022 GPA-828DU-M2 GPA-828DU-M1 GPA-828DU-HT GPA-828DU-HTD GPA-828-BP GPA-828-HH OKAYO high-power portable speaker set

For product purchases, please use "Okayo Direct" with after-sales service from OkayoJapan! https://ec.okayo-japan.com/ OkayoJapan Co., Ltd. provides audio equipment centered around small to medium-sized wireless speakers/amplifiers that can also be utilized for events and disaster prevention measures. Since it comes standard with a battery, there is no need for cumbersome power cords, allowing for use both indoors and outdoors. Additionally, a key feature is the ability to occupy one tuner for speaking only while pressing a button, enabling the necessary number of microphones (DL-8H Pro) to be in standby mode. This allows for the construction of traditional multi-user system configurations simply by "adding more microphones." For example, in situations such as committees, press conferences, and community briefings where there are a certain number of speakers, the need to pass microphones around is eliminated, making it very useful. With a cumulative total of over 6,000 units sold domestically, OKAYO products continue to spread across various industries. Leading the world in wireless communication technology, OKAYO ELECTRONICS.
