Description
<h1 style="text-align: justify;"><strong>The <a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> is a digital mixer with 18 inputs and 14 outputs. The <strong>SuperStrip</strong> of each individual channel is replaced in this model by touchscreen controls on the <strong>iOS app for iPad</strong>, which offers the same ability to adjust preamps, high-pass filters, parametric EQ, GEQ, gate, compressor, and pan as the version with onboard controls. 4 effects processors can be configured as inserts or sends from the channel or mix bus. The <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> integrates a 32 In/32 Out USB audio interface for multitrack recording to USB mass storage devices or for integrated use with DAW software. Through the <strong>QU-Pad (iOS) app</strong>, scenes and presets can be saved and recalled on the mixer.</h1><h2 style="text-align: justify;"><strong>Capture all the details with <a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong></h2><p style="text-align: justify;">The Allen & Heath Qu-SB has been designed from the ground up to deliver professional sound quality from input to output. The Qu-SB mixer features sixteen digitally controlled AnalogiQ preamps. The AnalogiQ preamp design has been perfected to offer transparency and minimal distortion, with extremely low noise floor. All while maintaining a warm and musical sound that some digital consoles unfortunately lack. Input signal conversion occurs at 24-bit with high-end, low-latency converters. The same applies to digital-to-analog conversion to ensure the same output quality.</p><h2 style="text-align: justify;"><strong>High-level effects and signal processors </strong></h2><p style="text-align: center;"><img alt="gli effetti della serie Allen & Heath Qu derivano dalla serie iLive" src="/images/uploads//effetti.jpg" title="gli effetti della serie Allen & Heath Qu derivano dalla serie iLive" />h</p><p style="text-align: justify;">The <strong>RackFX</strong> dynamics processors and effect algorithms of the <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> <a href="https://www.algameko.com/it/tag/i-mixer-digitali-della-serie-qu-di-allenheath">Qu</a></strong> series are derived from the iLive series. Some of the most renowned sound engineers have chosen to use RackFX during their tours for convenience and quality, preferring onboard effects over plugins or external effects racks. The <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> boasts 4 stereo RackFX engines, carefully crafted emulations of legendary classic reverbs, gated reverbs, delays, modulators, flangers, and much more. The effects are returned to the mix on dedicated return channels; therefore, they do not occupy mono or stereo input channels, and each stereo FX return has a dedicated 4-band parametric EQ.</p><h2 style="text-align: justify;"><strong>Total control via the QU-Pad app</strong></h2><p style="text-align: center;"><img alt="Tramite l'app Qu-Pad abbiamo a disposizione tutti i controlli della superstrip e tutte le funzioni del mixer" src="/images/uploads//channel strip.jpg" title="Tramite l'app Qu-Pad abbiamo a disposizione tutti i controlli della superstrip e tutte le funzioni del mixer" /></p><p style="text-align: justify;"><strong>The <a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB is entirely controlled via the iOS app (not available on Android) Qu-Pad.</strong> On its main screen, the master fader section is located on the left side of the screen, the controls for the various faders are in the central part of the screen, and at the top, there is the option to view effects and signal processors which can be selected on the left side of the screen.</p><h2 style="text-align: justify;"><strong>I/O Patching</strong></h2><p style="text-align: center;"><img alt="tramite I/OPatch possiamo gestire il routing routing completo del mixer" src="/images/uploads//in out patching.jpg" title="tramite I/OPatch possiamo gestire il routing routing completo del mixer" /></p><p style="text-align: justify;">Through the I/O Patch screen, we can set the signal path for inputs and outputs of a stage box connected via dSNAKE, monitor routing, and the configuration of the 32 USB channels if we want to connect the <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> to any DAW software.</p><h2 style="text-align: justify;"><strong>Effects Configuration</strong></h2><p style="text-align: justify;"><strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> has 4 internal stereo effects processors. These are effects found in the flagship <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> iLive</strong> digital mixing system and are based on emulations of popular effects that have become industry standards over time. We can access the effects linking menu via the <strong>'back panel'.</strong></p><p style="text-align: center;"><img alt="il signal flow degli effetti viene impostato tramite la schermata dedicata dell'app Qu-Pad" src="/images/uploads//fx routing.jpg" title="il signal flow degli effetti viene impostato tramite la schermata dedicata dell'app Qu-Pad" /></p><p style="text-align: justify;">From here we can select the signal flow of our effects.</p><p style="text-align: justify;"><strong>Mix>Return -</strong> Known as a “system effect”.</p><p style="text-align: justify;">It uses a bus to send a mix of channels to an effect and a dedicated stereo FX Return channel to add the "wet" effect to the original "dry" sound. It is used for effects such as reverb and delay. Choose which mix bus to use as input; for the <strong>Allen & Heath Qu-SB</strong>, the dedicated buses for this are FX1 and FX2. If you want to use FX3 or FX4 as another system effect, you can patch the effect to an input of Mix1-10 buses.</p><p style="text-align: justify;"><strong>Ch>Return –</strong> This is similar to Mix>Return</p><p style="text-align: justify;">System effect, but in this case it is fed from a channel rather than a mix of channels. It uses the assigned Direct Output as its source. Some examples include a delay on a vocal channel, a gated reverb on a snare, or a chorus added to the guitar.</p><p style="text-align: justify;"><strong>Insert –</strong> Here the effect is patched in-line with an input channel or master mix. It is inserted using the channel's Insert control. Effects applied with inserts have a Dry/Wet control to balance the effect with the original signal.</p><h2 style="text-align: justify;"><strong>DCA Groups</strong></h2><p style="text-align: justify;">The <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> gives us the ability to create <strong>DCA groups</strong> to control multiple faders simultaneously. These groups can be muted, and the command to do so can be mapped to the <strong>soft keys</strong>. To access the masters and to name and assign the groups, we use this submenu:</p><p style="text-align: center;"><img alt="tramite questa schermata possiamo assegnare con un tocco i canali che vogliamo ai gruppi DCA" src="/images/uploads//DCA groups.jpg" title="tramite questa schermata possiamo assegnare con un tocco i canali che vogliamo ai gruppi DCA" /></p><p style="text-align: justify;"> It can be useful to assign a mute or a DCA group to the effects returns, thus providing a quick way to mute or reduce effects between tracks.</p><h2 style="text-align: justify;"><strong>Inputs and Outputs</strong></h2><p style="text-align: center;"><img alt="Ingressi e Uscite dell'Allen & Heat Qu-SB" src="/images/uploads//in out.jpg" title="Ingressi e Uscite dell'Allen & Heat Qu-SB" /></p><p style="text-align: justify;"><strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> has 16 inputs for line-level signals on ¼” TRS connectors or for microphone signals on XLR connectors, a footswitch input, and 1 stereo line input on 2 ¼” TRS connectors. As for outputs, we have 10 mix outputs on XLR connectors, 2 XLR Main mix L/R outputs, a headphone output on ¼” TRS, a stereo MTRX 1-2 output on 2 ¼” TRS connectors, a dSNAKE port, USB type B for DAW connection, a <strong>Qu-Drive</strong> USB input for mass storage devices, and an RJ45 network port.</p><h2 style="text-align: justify;"><strong>Computer-Free Recording</strong></h2><p style="text-align: center;"><img alt="registrazione multitraccia diretta su memorie di massa USB" src="/images/uploads//qudrive.jpg" title="registrazione multitraccia diretta su memorie di massa USB" /></p><p style="text-align: justify;"><strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> features a built-in multitrack recorder, providing 18 channels of 48 kHz, 24-bit recording and playback directly to USB mass storage devices, making it easy to record shows or studio performances. A selectable stereo pair can be recorded along with the 16 mono channels, and multitrack audio can be played back to the 16 mono inputs plus ST1. In addition, Qu-Drive also provides stereo recording, patchable from any pair of Mix outputs, Main LR (pre, post, or summed to mono), or even from the PAFL bus, with 2-track stereo playback to ST3.</p><h2 style="text-align: justify;"><strong>AMM: Automatic Mic Mixer</strong></h2><p style="text-align: justify;"><strong>AMM</strong> is highly functional in applications such as conferences and meetings where multiple microphones are open simultaneously. <strong>AMM</strong> works by reducing background noise, minimizing the risk of feedback, and keeping all sound sources at the same level, ensuring that each speaker's contribution is heard clearly, thanks also to the D-Classic gain algorithm, inspired by industry-standard automixers.</p><h2 style="text-align: justify;"><strong>Customizable monitor mixes for musicians with the Qu-You app</strong></h2><p style="text-align: center;"><img alt="tramite l'app Qu-You i musicisti possono personalizzare i prorpi monitor mix" src="/images/uploads//qu-you.jpg" title="tramite l'app Qu-You i musicisti possono personalizzare i prorpi monitor mix" /></p><p style="text-align: justify;"><strong>Qu-You</strong> is an <a href="https://www.algameko.com/it/brands/allen-heath"><strong>Allen & Heath</strong></a> app designed for musicians, allowing up to seven artists to control their monitor mixes via WiFi using an iPhone®, iPad®, iPod Touch®, or Android device.</p><h2 style="text-align: justify;"><strong>USB audio streaming and MIDI control</strong></h2><p style="text-align: justify;">Want to live stream? Easy. Just send a stereo mix via USB, and your streaming software will do the rest. The <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> can be used as a multitrack interface; the device will be recognized by all computers with Asio drivers and the most commonly used DAWs including Logic, Cubase, Reaper, and Pro Tools. Standard MIDI control is sent via the USB connections and the network port, which allows us to map DAW faders using the <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> MIDI Control</strong> app, providing easy setup and emulation of HUI or Mackie Control protocols.</p><h2 style="text-align: justify;"><strong>Three-tier security lock</strong></h2><p style="text-align: justify;">For control security, three user profiles are available:</p><p style="text-align: justify;"><strong>Admin -</strong> has access to everything. Can configure the mixer and set user permissions and passwords.</p><p style="text-align: justify;"><strong>Standard - </strong>Can control the live mix but is locked out of system and configuration functions.</p><p style="text-align: justify;"><strong>Basic -</strong> Can only control faders and mutes and may be excluded from certain channels or limited only to custom fader levels.</p><p style="text-align: justify;"> Passwords can be set for each of these three users, which are required for access and surface lock. The Qu-Pad app follows the same user permissions. The administrator can set a separate password for Qu-You and Qu-Control users. Standard and Basic users can also be restricted to using only selected scenes.</p><h2 style="text-align: justify;"><strong>Robust and Quiet</strong></h2><p style="text-align: justify;">Made from cold-rolled 18-gauge Zintec steel, the chassis of the <strong><a href="https://www.algameko.com/it/brands/allen-heath">Allen & Heath</a> Qu-SB</strong> has been designed and tested to ensure strength and durability. </p>Silence is a precious commodity both in live sound and in the studio, and no one wants it ruined by the hum of cooling fans. Keeping this in mind, **Allen & Heath** has designed a series of mixers capable of optimal air recirculation without the need for fans.
