This Omnitronic PM-404F review covers the £225 four-channel DJ mixer. The PM-404F offers two phono/line channels, two line/line channels, per-channel filters, and an independent mic channel. All four channels can use the built-in Bluetooth receiver as a source, and the unit features a removable crossfader with an adjustable curve, reverse switch and a short cut-in distance. The mixer is housed in an all-metal chassis and is positioned as a budget four-channel option aimed at beginners and use in home or club settings.

Master and booth outputs are provided via balanced XLR and RCA, and the front panel includes mic, headphone and crossfader controls, a Bluetooth pairing button and a record output. Each channel has a two-band EQ and per-channel bipolar filters with fixed resonance. Line inputs are described as phenomenally loud while the phono inputs are quiet. Dimensions are 240 x 110 x 338 mm, the weight is 2.85 kg, and the PM-404F is around 12% larger in size than the Pioneer DJ DJM-250mk2.

The Omnitronic PM-404F is a four-channel DJ mixer designed to offer versatile connectivity and reliable performance. Each of its channels can handle either phono/line or line/line signals, making it adaptable to various input needs. The mixer includes an independent microphone channel, per-channel filters, and a built-in Bluetooth receiver that allows all four channels to utilize wireless audio sources. This feature enhances the mixer’s versatility for both home DJs and professionals handling requests.

The hardware features a removable crossfader that boasts an adjustable curve, reverse switch, and short cut-in distance, catering to DJs needing precision and customizability. Physically, the PM-404F measures 240 x 110 x 338 mm and weighs 2.85 kg. It is built with an all-metal chassis, ensuring durability. Outputs include balanced XLR and RCA for the master and booth, although 6.3mm jacks for booth outputs are not present. The front panel is equipped with controls for microphone, headphones, and crossfader, alongside a dedicated Bluetooth pairing button and record outputs.

Each channel is equipped with a two-band EQ and per-channel bipolar filters with fixed resonance to allow basic sound adjustments. Its line inputs are particularly loud, whereas the phono inputs are quieter, accommodating different source priorities. Compared to its predecessor, the PM-404F adds per-channel filters and competes well in the budget mixer category, especially for beginners or smaller venue setups. This mixer is slightly larger, measuring 12% more than the similar Pioneer DJ DJM-250mk2.

The PM-404F uses a two-band EQ on each channel and does not include a three-band EQ. Each channel also features per-channel bipolar filters with fixed resonance. A quoted observation states: “The PM-404F has a two-band EQ, the same as Omnitronic’s rotary TRM-202, but without its cousin’s three-band isolator, meaning frequency sculpting is much less flexible.” The addition of per-channel filters differentiates this model from the PM-422P, which had a three-band EQ but no filter.

A quoted summary of the mixer’s sonic character reads: “Its sound profile is a bit flat, but tracks sum well enough, and while the low-end doesn’t have half as much attack as more expensive mixers, I can see the PM-404F being a solid pick for use at smaller venues.” Line inputs are described as phenomenally loud, while the phono inputs are quiet. These input-level characteristics affect how sources need to be matched when preparing mixes.

All four channels can use the built-in Bluetooth receiver as a source, and this capability is described in a quoted line as “a win for everyday home listening and DJs that deal with a lot of requests.” The two-band EQ combined with the per-channel filters constitutes the primary tone-shaping toolkit on the PM-404F. The mixer’s quoted strengths include its I/O roster and the presence of per-channel filters alongside Bluetooth functionality.

The PM-422P is described as Omnitronic’s previous four-channel model and features a three-band EQ while lacking a filter. This contrasts with the PM-404F lineup decision regarding EQ and filters as indicated in the source material. The PM-422P’s three-band EQ represents a different approach to frequency control compared with other models mentioned in the same context. The PM-422P is presented as the direct predecessor within Omnitronic’s four-channel range.

Behringer’s DJX900USB is priced below £200 and is noted to include a suite of sound effects. A quoted observation states:

Behringer’s DJX900USB comes in even cheaper at under £200 and has a suite of sound effects, though online commenters complain about its build and sound.

The DJX900USB is therefore positioned as a cheaper alternative in the budget four-channel market but carries reported user feedback about build and sound quality. The Reloop RMX44BT is listed at around £270, placing it at a different price point compared with the other two alternatives.

Taken together, these models differ across price, EQ configuration and feature sets, with the DJX900USB emphasising effects and the PM-422P offering a three-band EQ without filters. The RMX44BT’s listed price of around £270 identifies it as a higher-priced option among the three alternatives cited. These factual differences are presented in the source material to contextualise the PM-404F within the budget four-channel mixer segment.

At just £225, the PM-404F is one of the most affordable four-channel DJ mixers on the market.

The PM-404F offers two phono/line channels, two line/line channels, per-channel filters, an independent mic channel, and Bluetooth capability.

The removable crossfader is also simply superb for the price – it’s no Innofader, but has an adjustable curve, reverse switch, and tiny cut-in distance.

Omnitronic scores another huge win with the PM-404F’s input and output roster.

Its sound profile is a bit flat, but tracks sum well enough, and while the low-end doesn’t have half as much attack as more expensive mixers, I can see the PM-404F being a solid pick for use at smaller venues.

The PM-404F has a two-band EQ, the same as Omnitronic’s rotary TRM-202, but without its cousin’s three-band isolator, meaning frequency sculpting is much less flexible.

A two-band EQ isn’t the end of the world, but the PM-404F is a budget mixer that will be bought by those looking to get comfortable with club-style workflows.

I’m less of a fan of the cue buttons, which are made of a tacky rubber and wobble around their central point of contact.

All four channels have the option to use the built-in Bluetooth receiver as a source — a win for everyday home listening and DJs that deal with a lot of requests.

Behringer’s DJX900USB comes in even cheaper at under £200 and has a suite of sound effects, though online commenters complain about its build and sound.

Still, if your only concern is the number of channels on offer, then fantastic I/O, surprisingly good sound quality, per-channel filters, and a handy Bluetooth feature make the PM-404F a solid value buy.

CONCLUSION

At £225 the PM-404F is presented as an affordable four‑channel DJ mixer that combines two phono/line channels, two line/line channels, per‑channel filters, an independent mic channel and a built‑in Bluetooth receiver usable on all four channels. It includes a removable crossfader with adjustable curve, reverse switch and a short cut‑in distance, and offers balanced XLR and RCA master and booth outputs. The unit is housed in an all‑metal chassis, measures 240 x 110 x 338 mm and weighs 2.85 kg, and is around 12% larger than the Pioneer DJ DJM‑250mk2. The feature set is positioned toward beginners and use in home or smaller club settings.

Noted limitations include a two‑band EQ per channel rather than a three‑band EQ, phono inputs that are quieter compared with the phenomenally loud line inputs, and a sound profile described as “a bit flat” with less low‑end attack than more expensive mixers. The PM‑404F lacks 6.3mm jacks for booth outputs. The removable crossfader is described as having strong performance for the price but not matching an Innofader. These strengths and constraints together define the PM‑404F’s value proposition within the budget four‑channel mixer segment.
