I was originally thinking of getting a used RX1602, but I'm now glad to have not gone down that path.
When intending to buy a used Eurorack Pro RX1602 Mixer, it may be worth considering a new one instead. They appear to hold their price well at around AUD $150 to $200 (if you can find one at all). There is not a lot of money saved chasing a used RX1602 mixer. A new one, on the other hand (at between AUD $210 to $280), comes with a three year warranty (with conditions) and possibly even free shipping.

Review and Description
(Rating 5.8 / 10 - would / could have been better but didn't outlast its warranty period)
The 19" rack mount Eurorack Pro RX1602 Mixer is compact, simple and effective solution when you need to mix up to 8 stereo Line Level signals. This is a 1RU (single rack unit), no-frills, but a good audio quality mixer that delivers exactly what it claims. The RX1602 is Ideal for submixing, particularly when you just need a single stereo output.
This article is about the original RX1602, not the V2 version.
Up until 26/04/2020 ... The Eurorack Pro RX1602 Mixer had been a part of my rig for around 2½ years, with a daily run-time between 2 to 4 hours (approx. 2500+ hours total). While quietly practicing one evening, the RX1602 failed spectacularly, with much loud noise. Fortunately (perhaps) 6 months prior to the 3 year (conditional) warranty expiring.
Most of this review was already completed at the time of failure, but has since been updated where appropriate. Going forward, there is a very good chance that the RX1602 will in due course be replaced by the Sampson SM10 - Line Mixer, which has some additional features - just thought that might be worth a mention.
The field of analogue rackmount line mixers is not a huge one and it quickly gets much smaller when you add the criteria: 16 channel or 8 channel stereo and 1RU. If you open the link below there is a search prepared for those who are after mixer product comparisons.

An important pre purchase consideration was a device that used minimal rack realestate.
From a functional perspective, the layout of the RX1602 Mixer is about as tightly packed as you can get while keeping to a 1RU format.
There are controls on the rear panel (Level Switch +4dB / -10dB) that I would have preferred to have on the front and there are internal circuit board links (Pre / Post Fade Monitor) that I would also have preferred to be switches available on the front panel.
While Behringer call this is a 16 Channel mixer, it is really only 8 channels that can be implemented as either Mono or Stereo. If used for 16 distinct mono channels the balance would become a part of the level control and there would be no actual panning available.
Behringer claim it to be an Ultra-Low Noise Line Mixer. While prefixes like ultra tend to make me Ultra-Suspicious ... well ... it is quiet. The Eurorack Pro RX1602 Mixer has no noticeable noise issues and can deliver full output without signs of distortion - I would not hesitate to call it 'Studio Grade'.
Each of the 8 Stereo (or Mono) Channels consists of:
- Monitor / FX Send Level Control (Mono).
- Balance Control for stereo (Pan Control when used with Left / Mono input only).
- Mute Switch with an LED that doubles as a Clip Indicator.
- Channel Level Control with up to 15dB Gain. Unity Gain at 12 o'clock position.
See my illustration below showing Channel [15/16] as an example. Click on the illustration for a larger image of the whole mixer.
To the right of the 8 channel sections there is the Output and Monitoring section (shown above):
- Monitor / FX Send Master Level Control, for Mono Output via 6mm (1/4") jack on the rear of the device. Can be routed to headphones via To Phones switch.
- Main Left and Main Right Level Controls set the stereo Left / Right output levels
This could have been done better.
- Level Meters 8 segment LED display (nothing exciting here)
1st segment green - Just a Power On Indicator
Segment 2 to 7 are -24dB to +12dB
Segment 8 red - Clipping Indicator
- Headphones Level Control.
- Headphones Output Stereo via 6mm (1/4") jack.
Could be used as an AUX Stereo Out.
- Power Switch at the far right.
See illustration above showing Output Controls and Metering.
The rear panel of the Eurorack Pro RX1602 Mixer consists of:
- 8 balanced Stereo (or Mono) input sections (Channels 1 through 16). Each channel pair with an input level selection switch for +4dBu (Pro Audio) or -10dBV (Consumer Audio).
- An unbalanced Mono Monitor Output.
- A Stereo Main Output.
- DIN Power Connector.
- Compact 1 RU Rack Mountable.
- 8 Stereo (or Mono) Channels is a very useful / useable number of channels.
- Monitor / Effects Out is handy to have (e.g. For foldback or other Mono Send).
- Low Noise.
- Adequate Headroom (I've never seen the Clip Indicators come on).
- All detented rotary controls - useful for matching settings across channels.
- Shielded torroidal transformer used with power supply helps to reduce noise. Torroidal transformers are generally more efficient, smaller and quieter - and in this case probably necessary to be able to fit a transformer with +15V | 0V | -15V secondary windings into a case with only 1RU height.
- The +4dB / -10dB Level Switch should be on the front panel. When the RX1602 Mixer is rack mounted (as mine is), gaining access to the back to make changes is often a near impossible proposition.
- Pre / Post Fade Monitor should also be available from the front panel via a switch. Having to open the case and disassemble the mixer to add or cut a jumper lead on an internal circuit board is
rather barbaric approach - which amongst other things instantly voids the device's warranty - even though Behringer expressly explain exactly how to perform this procedure in the manual.
I purchased some very small switches, intending to add Pre / Post Fade Monitor switching to the back panel, to at least have that option - but, there's really no space for them.
- The front panel Mute Switch lights are red when the channel is muted, are off when the channel is active and green when there is clipping - not at all intuitive.
Green for on, red for clipping and off for muted, would have made more sense.
This would have been more challenging electronically, but you know, that's what you pay (those clever German?) engineers for.
- The separate Left and Right Master Output Level Controls (mentioned as a feature in the literature - really!) are nothing but a pain in the arse! - Having to change two knobs to adjust the system Output Level of a Stereo Device is at best a silly idea. A Dual Ganged pot (potentiometer) with independent Left / Right adjustment would have been a far superior solution and greatly improved ease of use.
All new and registered Behringer products come with a 3 year limited warranty. The catch of course is that the product should be registered within 90 days of purchase and the warranty is not transferable upon resale ... and you have to jump through their hoops, which is to say they try to put you off from doing this [For Warranty Info - Please go here].
There is nothing flash or frivolous about the the Eurorack Pro RX1602 Mixer. It is a relatively simple 1RU workhorse, designed to save space and money. It does both splendidly, but of course with some, perhaps to be expected limitations.
While the unit's power supply design is about as simple as it gets, it does make use of a shielded torroidal transformer (generally a sign of higher quality design) which is definitely a contributor to the better than average noise performance.
The RX1602 does a fine job for what it is - and is reasonable quality, but could be improved. The one I purchased almost outlived the three year warranty period. A less than spectacular outcome for a device that doesn't even have high output levels and was not under any kind of physical stress.
Would I recommend this mixer - No. I replaced it with a Samson SM10. Twice the price but a much better quality piece of gear.
I did shoot off an inquiry email to where I purchased the RX1602, but never got a reply. ;-)
So anyway, the RX1602 case is on the bench now and open.
At a quick glance I'm seeing some (minor looking) heat issues with the power supply section. The fuse of course is open circuit, but it's the fuse type that was a surprise. It is a slow-blow 350 mA.
This explains why there was about 30 seconds of most horrendous noise (very reminiscent of highly amplified mains hum) from the amplifier which is fed by the mixer, before the grand silence when the fuse finally blew. This could be relatively fortunate if the damage is confined to the power supply components.
It should be noted though, that the choice of fuse type (slow blow) gives a clue to the designer's expectations of this device. In this case, they are expecting that the RX1602 will on occasion over-reach its electrical limits. But rather than design/provide a better power supply, and to prevent the thing from constantly blowing fuses, a slow blow fuse is used to 'tolerate' these transient specification over-runs.
Common sense should suggest however, that there may well be a limit to how many times or for how long that will work, before component stress leads to ultimate failure. Well, it seems that around about 2,500 run-time hours will do it, by my estimation.
Another fine example of Behringer's design ethic of pushing everything to max, and then, just a little bit more. Got to make room for those new models.
Simply put, it's no doubt at least a part of the reason why Behringer's 'German designed' shit, occasionally blows up.
