The Roland M160 is a rackmount 16-channel mixer ideal for keyboard rigs & home recording setups and can also be used as a summing mixer. It’s a compact unit in a 4U rackmount box and all connections are on the back panel, headphone jack excepted

Each channel has a linear fader, pan pot, three echo sends and one aux send. The first two channels are sensitive enough for microphones (-50 to -10 dBm) and the rest are line inputs (-20 to +4 dBm)

The three echo sends are post-fader and the aux send is globally switchable between pre and post-fader. Echo sends are mono and returns are stereo (mono if just the L jack is used). The aux send & return is mono

The headphone output is fed by the pre-fader mix output, and the back panel has a “Phones Mix In” jack to allow other sources to be monitored simultaneously

Roland has made provision for stacking multiple mixers: the back panel has bus in jacks for the four sends, so two mixers can share the same effects & aux sends. The mix out from a second mixer can be routed to a stereo echo return or patched to two channels. In this way it’s easy to combine the M-160 with other mixers

“It’s a 19″ rack mixer. Has good faders and good knobs. Feels very solid which is a good point. The thing has 3 buses, 2 auxes and 4 sends & returns”

“It sounds very clean and natural šŸ™‚ I really like this one. It would be in my rack for the next couple of years”

The M-160 packs a lot into a relatively small front panel but the layout is logical & easy to use. The channel faders and input pots have a nice feel and, with the exception of a broken master aux send knob, the knobs & fader caps are all in perfect condition. Each channel has a dual-colour LED to show signal & peak level and the main output has a pair of LED peak meters

The M-160 is ideal for submixes, headphone mixes, keyboards, effects returns, summing & etc – anything that requires lots of inputs in a small space. The three effect sends (plus an aux) make it easy to add reverbs and effect returns don’t eat up channels. It’s a great utility mixer & general problem solver

There’s lots of room inside the chassis and on the back panel for modifications, so if you wanted to fit D-sub connectors for inputs, add a 1/8″ socket for headphones or graft in a bus compressor, there’s plenty of space to do it

All inputs & outputs are on jacks. The main output is also on separate, balanced XLR connectors at a nominal +4 dBm level. The front-panel headphone jack has a dedicated volume control The unit has a mixture of operating levels. Main outputs and sends are a nominal +4 dBm, line inputs are -20 dBm, apart from inputs 1 & 2 which are -50 dBm, and the phones mix in is -10 dBm. The returns are globally switchable between +4 and -20 dBm This may seem like a big mish-mash, but it's actually well judged. The M-160 inputs work well with synthesisers, which typically produce lower levels than pro gear, whilst the outputs will interface with studio equipment working at a nominal +4 dBm or with semi-pro equipment at -10 dBm
19" 4U device suitable for all 19" racks. 230 Volt AC with a short, captive power cable with a standard UK mains plug
Owners manual
Very good used condition. There is damage to the left-hand rack ear at the lower mounting hole, some rack rash and a broken knob on the master aux send, but it's in good shape overall. Some of the pots are a little noisy but quieten down after a bit of exercise. Tested & working 100% All vintage gear will have case scratches and marks. It may also have, or develop, noisy pots and switches. I make my descriptions as accurate as possible and note any existing defects. I test each item before shipping, and and supply a test sheet, but please understand that vintageĀ gear will not be perfect and adjust your expectations accordingly
