3.5mm Mono Jack Plug to Single RCA Cinch Plug Cable 3m [3m/3m]

Thanks heaps! Could I use this one? https://www.amazon.com.au/6-35mm-Interfaces-Microphones-Guitar-Production/dp/B0F3HXNGTV?th=1 The Eris 5 has a single RCA input (unbalanced) at the back. Presumably for using them as a L&R speak system. Could I use that input as a mono signal with a cable like this?https://www.amazon.com.au/kenable-3-5mm-Single-Phono-Cable/dp/B019M5AFDA/ref=sr_1_4?crid=27FI1F95SUPGS&dib=eyJ2IjoiMSJ9.e2GRepRo_FnsNnkRK2TVANlvW741W9CjbLhIVJi2HNm2j3R2HVwXFrysDJAOkHoH10Zw1NN8ZaP4pV-UZwalZV1UgTH24ZCZrBbU6IKCizqxQcydSKfU0YazIT5YJbEn3ZQPeh16GrPrwwnsUKutsCLYe_6bQVtuP8kZiga3rOVIQFHNgbZUTxG7XNyWMgvg1OLcwtA4aQWZLkpsRT4ryghQAcXPzTqp0q4Qj67ZIh3LJNmQJpAUQOMVVs3Ob7ZmPzqDJoORM4UhnIfE5yl_Z7eQwNd3WqM1UACY9kiekI0.xq_9wSkNYlgQGY6a9nAglYm_EJ7v_Xs8ku_Bsyhi85s&dib_tag=se&keywords=stereo%2Bto%2Bsingle%2Bmono%2Brca&qid=1781672418&sprefix=stereo%2Bto%2Bsingle%2Bmono%2Brca%2Caps%2C221&sr=8-4&th=1

wow ok. thanks very much! Could I use the (unbalanced) RCA input, using a stereo (3.5mm) to SINGLE RCA cable like this: https://www.amazon.com.au/kenable-3-5mm-Single-Phono-Cable/dp/B019M5AFDA/ref=sr_1_4?crid=27FI1F95SUPGS&dib=eyJ2IjoiMSJ9.e2GRepRo_FnsNnkRK2TVANlvW741W9CjbLhIVJi2HNm2j3R2HVwXFrysDJAOkHoH10Zw1NN8ZaP4pV-UZwalZV1UgTH24ZCZrBbU6IKCizqxQcydSKfU0YazIT5YJbEn3ZQPeh16GrPrwwnsUKutsCLYe_6bQVtuP8kZiga3rOVIQFHNgbZUTxG7XNyWMgvg1OLcwtA4aQWZLkpsRT4ryghQAcXPzTqp0q4Qj67ZIh3LJNmQJpAUQOMVVs3Ob7ZmPzqDJoORM4UhnIfE5yl_Z7eQwNd3WqM1UACY9kiekI0.xq_9wSkNYlgQGY6a9nAglYm_EJ7v_Xs8ku_Bsyhi85s&dib_tag=se&keywords=stereo%2Bto%2Bsingle%2Bmono%2Brca&qid=1781672418&sprefix=stereo%2Bto%2Bsingle%2Bmono%2Brca%2Caps%2C221&sr=8-4&th=1
