Mini size and powered by DC 5V, easy to carry and convenient to use in most scenarios. Warm tips: 1. Without power adapter, and EQ5 needs to be powered by separate USB power supply, don't use the USB port of computers or share the power supply with audio source, otherwise common ground noise will be caused.2. Stereo RCA and 3.5mm AUX input are in parallel, two inputs and outputs will work simultaneously, so please don't connect RCA and 3.5mm AUX input at the same time avoid signal mixing.3. EQ5-PRO can input and output audio signal without power supply in bypass mode, but the signal without any preamplification, the VU meters also don't work.

TOA 900 Series EQ-910A mono Graphic Equalizer 10 band line or mic in/out WORKS!
ONE NICE TOA 900 Series EQ-910A Graphic Equalizer Super reliable brand! Super reliable product! PICTURES ARE SAMPLES - The product you receive will be one or like one of the ones shown, (select QTY2 if you need a pair for stereo) all have some signs of use/storage or scratches. Fully working and tested does not include any front cover, but there are 2 stand off posts you can attach a cover to if needed. ONLY WHAT IS SHOWN IS INCLUDED MODEL NUMBER(S) MARKED ON THIS ITEM IS: EQ-910A DIMENSIONS of THIS ITEM (In APPROX INCHES) ARE: 8.5x9x3.5 Z Long (Deep) x X Wide x Y High Approx. Unpacked net weight: 5lbs 6oz WHAT WAS TESTED ON or WITH THIS SPECIFIC ITEM: Plugged into power, connected an audio source in and out and tested all faders, EQ in/out Hi and Lo cut, gain. Also we tested with a mic. Although I believe these are designed as line level devices, we were surprised to find plugging in a Shure SM58 mic to XLR in and the xLR output to an XLR mic jack on our mixer amp, it had enough level to pass good level audio and allow tonal adjustments, so I guess if you have a good gain structure, you can add one of these EQs as an individual mic equalizer. (note we tested with our mixer amp phantom power OFF, and do not recommend using with a phantom powered system or mics as that could damage the input on this unit) May work good for a ham CB radio mic EQ as well depending on your impedance and levels. WHAT WE FOUND:* Light comes on, all controls affected sound as expected. *To assist our buyers, we test most items before listing as noted above. This is only to guide you as to what we experienced and does NOT guarantee the same results when used in your situation or with variables at your end. ----------------------------------------------------------------------------------------------------- SAFE, HONEST SELLER— See our HIGH FEEDBACK and bid confidently!

SHIPPING ARRIVAL TIMES: · We generally ship items within same day or up to 1 - 5 business days depending on our schedule, then it takes an additional 2-6 BUSINESS DAYS in TRANSIT, depending on your location, so it may take 1-2 weeks before your item arrives.
