Thank you for viewing. This is a Roland U-110 sound module (body only). It's quite old, but it's the first model in the U-series, a groundbreaking PCM sound module at the time. It has 99 built-in sounds and can use up to four SN-U110 series expansion cards simultaneously, the most in the series. The unit has been tested for basic functionality (e.g., sound generation via MIDI input) after power-on, but please note that not all functions have been fully verified. The backup battery has been replaced. *Sound expansion cards are not included. 【Specifications】 ■ DC-PCM System 31 voices / 6-part multitimbral 1U rack-size sound module. 99 tones. 【Set Contents】 ■ Roland U-110 Body ■ Instruction manual and other attached documents ■ Box included *There is damage due to aging 【Condition】 ■ Operation confirmed (power-on, basic operation, and sound confirmation) ■ Battery replaced ■ Appearance: No noticeable scratches ■ Dimensions: Width 48.2 x Depth 35.8 x Height 4.5 cm ■ Weight: 4.5 kg Shipping will be done using the product box as is, so please understand.
