MACKIE 1604 VLZ3 PDF

Mackie's VLZ Pro mixers gained a reputation for punching above their weight. Could this next generation do even better? Mackie's range of compact VLZ mixers have acquired almost legendary status over the years as solid, reliable, versatile and good-sounding desks. There was a brief manufacturing period when internal wire links became somewhat undependable, but this issue was resolved quickly and easily on those desks that suffered from it, and the reputation remained untarnished in the minds of most users, myself included. The manufacturers seem proud of the advances made, citing an improved mic preamp design, more refined EQ and improved mix-bus headroom. Although the VLZ Pro models punched well above their weight anyway, these are all areas in which they were, if you were to be really picky, a little weak.

Mackie's VLZ Pro mixers gained a reputation for punching above their weight. Could this next generation do even better? Mackie's range of compact VLZ mixers have acquired almost legendary status over the years as solid, reliable, versatile and good-sounding desks. There was a brief manufacturing period when internal wire links became somewhat undependable, but this issue was resolved quickly and easily on those desks that suffered from it, and the reputation remained untarnished in the minds of most users, myself included.

The manufacturers seem proud of the advances made, citing an improved mic preamp design, more refined EQ and improved mix-bus headroom. Although the VLZ Pro models punched well above their weight anyway, these are all areas in which they were, if you were to be really picky, a little weak. In fact, it always struck me that the remarkable quality of the original XDR mic preamps was let down by the rather average mix bus and limited headroom imposed by the rest of the mixer.

So I was as keen as anyone to see if the new VLZ3 really could raise the bar to a new level. The ergonomic and operational features of the new desk remain almost identical to the previous model. In fact, the only obvious differences I could find are changes to the centre frequencies of the four-band EQ on the stereo channels and the inclusion of a mains input voltage selector. The block diagram published in the handbook is even identical to that for the previous generation console.

But then, it obviously makes sense to follow the old adage of 'if it ain't broke, don't fix it', since the mixer has always been a well thought-out console, which is both easy to use and very versatile. Why change that? Given the operational similarity to the previous model I'll only give a brief guided tour, as there is little new to see here.

Phantom power is switched globally across the whole console, but only appears on the XLR sockets, of course. A second TRS socket is provided on each channel for an unbalanced insert point which can also be 'bodged' to serve as a pre-fade direct output by partially inserting an output plug. The second pair have orange knobs and are fixed post-fader. As with previous designs, a centre detent identifies the unity gain position, and a further 15dB of gain is available if required.

The absence of such a switch is frustrating, as it would not only allow unused EQ circuitry to be bypassed, it would also make it far easier to determine whether EQ adjustments are actually helping to improve a source or just making it louder and brighter! At the bottom of the channel strip is a pan control Adjacent to the top of the 60mm fader are two dual-purpose LEDs. A red one flickers when the signal level nears clipping, and lights steadily when the channel Mute button is pressed.

The first two stereo channels, and , are equipped with mono mic inputs as well as stereo line inputs. The mic input appears on both channels of the stereo pair and is equipped with the same 60dB gain trim and high-pass filter as the mono channels. There is no insert point on these stereo channels, though, as the socket has been reallocated to serve as the second channel line input.

In all cases, plugging a source into only the left line input routes the signal to both channels in dual mono. All the stereo channel facilities are identical to the mono channel: the same four Aux sends are provided, along with the same bus-routing switches, and so on.

The only difference is that instead of a three-band EQ with sweep mid, the stereo channels are equipped with a fixed four-band equaliser. The top and bottom sections provide the same shelf responses at 12kHz and 80Hz, but the two mid bands centre on 2. This is the first radical departure from the previous version of the desk, as that had centre frequencies of 3kHz and Hz.

The new lower settings — especially the low mid — seem to be much more appropriate for tweaking commercial music and thinning out sources like synth pads. Clearly, this change has resulted from the feedback of end users, and is a worthwhile improvement. The output section of the console is, once again, almost identical to its forebear. Only the first two aux sends are provided with master level controls, again with unity gain centre detents and 10dB of extra gain available.

Each of these aux sends also has a solo after fade button and associated warning LED. Aux sends three and four simply appear on balanced ground compensated output sockets on the rear panel, with no master level controls, and no AFL monitoring. Below the two aux masters is a pair of LEDs to indicate the presence of mains power and the status of phantom power, both being switched on and off from the rear panel.

To the right of the aux send controls is a section handling four dedicated stereo effects returns. Each has an input level control with up to 20dB of gain, and each is routed to the main stereo mix bus by default. However, the first return can also be sent as a mono sum to the aux 1 bus through a separate level control, and the second return can be routed similarly to aux 2. These facilities are ideal for sending reverb to a vocalist's headphones, for example.

The third stereo return can be switched away from the main stereo bus and routed, instead, to either pair of subgroups. The four stereo returns can be solo'd en masse by a dedicated push-button. A group of four push-buttons is used to select the monitored source from the stereo tape return, each pair of subgroups, and the main stereo mix bus.

The tape return is equipped with a rotary level control, providing up to 20dB of gain, and a push button allows the signal to be routed straight to the main mix bus, if required. The tape inputs are provided on a pair of RCA phono sockets, along with a second pair to provide a recording output from the stereo mix bus, all optimised for dBV nominal levels. A 12V gooseneck lamp feed is also provided on a BNC connector.

Separate level controls are provided for the main control-room monitors and the dual headphone output, as well as a separate level control for setting the solo'd signal volume. The headphone amplifier is a very beefy design indeed, capable of producing quite deafening levels — so use with care. Finally, at the bottom of the section, the four subgroup faders are provided with buttons to route their outputs to either or both of the two mix bus channels.

Turning now to the rear panel, all but the main outputs are balanced using the versatile ground-compensated topology, while the main outputs XLR and TRS feature fully active output drivers. The first eight input channels are provided with post-fade direct outputs on TRS sockets, and the four subgroup outputs are doubled up across eight output sockets, to make connection with an eight-track recorder simpler. Group 1 also feeds output 5, group 2 feeds output 6, and so on.

The four aux sends are also presented here on TRS sockets, as are the four stereo returns. The control room monitoring outputs are on another pair of TRS sockets, along with duplicates of the main mix-bus outputs, and a pair of unbalanced inserts are provided for the main mix bus.

A summed mono main output is also provided on a single TRS socket, with a separate volume control adjacent to the socket. A pair of male XLRs provides the main stereo mix output, and a recessed push-button allows the level to be attenuated by 40dB, allowing the output to feed the mic input of a recorder or another mixer.

I've already mentioned the two rocker switches which turn on the mixer and activate phantom power. A recessed slide switch determines the input mains voltage, with options for , and V AC. The mixer's steel-framed chassis is as strong and sturdy as we have come to expect, and the front edge under the faders is recessed on this new range to form a convenient carrying handle. The overall styling has been refreshed to look more modern than its predecessors, but the revised form hasn't detracted from the function in any way.

Unlike the earlier versions of the console, the connector section is fixed and can't be rotated to facilitate rack or desktop mounting, but rackmount ears are optionally available, if required.

Usefully, a series of graphics printed on the rear panel shows the appropriate connector wiring requirements. The VLZ3 series compares favourably with most analogue mixers in the same price range. If you are looking for alternatives for comparison, Mackie's Onyx series offers similarly good quality, but with a much more coloured, warmer sound.

All the key features that we associate with Mackie desks have been retained: sealed potentiometers, steel chassis, control knobs designed to pass forces to the console metalwork rather than into the pot mechanisms, and so on. Most of the improvements to the new console are hidden beneath the top panel, and concern refinements to the circuitry. An important improvement in the new XDR2 preamp is a significantly extended frequency response, but not at the high end: the vital change is in the low frequency LF extension.

In my experience, LF headroom and extension is what differentiates an average mic pre from a great one, and it also helps to avoid heavy phase shifts building up as the signal passes through other circuit stages. The distortion figures are also much improved, with total harmonic distortion falling to a superb 0. RFI rejection also remains a cornerstone of the input design — important when the circuitry has such a wide bandwidth — and the input impedance has been raised from 1.

The other major change to the console is in the mix bus, with a revised topology that keeps the signal level depressed through the mix amps and bus faders, before making up the gain in a post-fade buffer. This provides greater headroom, making it easier to mix lots of hot signals with less distortion. Indeed, the overall console THD figure has been halved in comparison with the previous design, to just 0. Strangely, though, the crosstalk figures appear to have worsened slightly in the new console, up 2dB from dBu in the previous console to dBu in the new VLZ3.

Similarly, the main mix noise with all faders at unity is also a little worse, up 4dB from to In practice, though, I doubt whether anyone would be able to tell the difference, and with the greater headroom and lower distortion offered it is now easier to drive the desk harder than before anyway, permitting a greater dynamic range.

I have long been a fan of the original VLZ Pro consoles and their XDR preamps, which have always been amongst the best of any budget console and, for that matter, nipping at the heels of many high-end consoles. Indeed, I regularly use a little VLZ Pro mixer for recording 'serious music', with excellent results. The new design seems to have retained the sonic neutrality of the original as opposed to the definite 'sonic flavour' introduced with Mackie's Onyx preamp design , but it is noticeably cleaner and less strained when handling hot signals.

Noise levels seem much the same, but the bottom end sounds fuller and more natural. Mix bus headroom was always a weak point in the original designs, but there has been a significant step forward with the VLZ3.

The other important change is to the stereo channel EQ. Reducing the centre frequency of the low-mid band has made it much easier to apply tonal correction that works musically.

It's surprising just how significant that change is in practice. Overall, then, it seems clear that the Mackie engineers have been listening to customer feedback, and have used it to improve an already very good budget console to something that can stand proud among many high-end professional designs. Based very closely on the previous VLZ Pro model, the new VLZ3 retains the key features of the original but delivers even better sound quality, thanks to several critical circuitry revisions.

The sonic neutrality of the previous generation of console has been retained, but with greater headroom and a less strained sound when driven hard. Alternatives The VLZ3 series compares favourably with most analogue mixers in the same price range.

Pros Even better sound quality, overall. Robust build but with refreshed styling. Versatile facilities. Professional quality at budget prices. Cons The lack of an EQ bypass still rankles. Modest changes to crosstalk and noise specs illustrate the 'swings and roundabouts' nature of circuit design! Summary Based very closely on the previous VLZ Pro model, the new VLZ3 retains the key features of the original but delivers even better sound quality, thanks to several critical circuitry revisions.
