It\u2019s a true stand-alone 16-track production recorder compact enough for bag work, yet engineered as a serious location tool with disciplined metadata, redundancy, and professional sync.<\/p>\n<p>A major part of the SX-R4+ appeal is that it delivers this performance in a machined aluminum chassis with a genuinely portable footprint (200 \u00d7 50 \u00d7 144.5 mm) and very low weight for its class (960 g without battery \/ 1.2 kg with 48 Wh battery).<\/p>\n<p>The machine is also built for real set pace: it boots in 4 seconds and is ready to record immediately. Its 2.4&Prime; pressure-based touchscreen remains usable in challenging conditions when gloves make capacitive screens impractical, you can still operate the UI reliably using a pen\/stylus.<\/p>\n<p><strong>Fast operation and user-assignable shortcuts<\/strong><\/p>\n<ul>\n<li>\n<ul>\n<li>Beyond raw audio performance, the SX-R4+ is built to stay fast on set. Key functions and the most-used menus can be assigned to quick-access \u201chot spots\u201d, so the operator can jump straight to what matters without digging through layers.<\/li>\n<li>Depending on the context, a simple press or a long press on a designated area of the touchscreen can trigger an action or open a specific menu. The same principle applies to the front-panel rotary\/push control: press and long-press can be mapped to different functions for immediate access during takes.<\/li>\n<li>This customizable action concept extends to compatible SONOSAX expansion accessories equipped with buttons and\/or rotary controls, allowing operators to assign shortcuts and functions to external controls to match their workflow.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Recording, redundancy, and metadata<\/strong><\/p>\n<ul>\n<li>\n<ul>\n<li>The SX-R4+ records up to 16 tracks as uncompressed BWF with iXML metadata.<\/li>\n<li>It supports 44.1 to 192 kHz at 24-bit or 32-bit and offers 0.1% pull up\/down for NTSC workflows.<\/li>\n<li>For reliability on set, the SX-R4+ uses dual SD cards and can record to both simultaneously in Mirroring mode for instant redundancy.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Inputs &amp; digital expansion including the 26-pin AES input connector<\/strong><\/p>\n<ul>\n<li>\n<ul>\n<li><strong>4 \u00d7 XLR-3F inputs<\/strong>, individually configurable as:\n<ul>\n<li><strong>Analog<\/strong> mic\/line (electronically balanced) with phase reverse, 48 V phantom, LF cut, and front-panel level control<\/li>\n<li><strong>Digital<\/strong> AES3 or AES42 (transformer balanced) with individual ASRC, plus phase reverse, LF cut, and front-panel level control<\/li>\n<\/ul>\n<\/li>\n<li><strong>2 \u00d7 balanced line inputs<\/strong> on TA-3 with front-panel level control<\/li>\n<li><strong>TA-3 AES3 I\/O<\/strong> (transformer balanced) that can be switched as input or output<\/li>\n<li><strong>3M MDR 26-pin connector<\/strong>: 4\u00d7 AES inputs + command bus<\/li>\n<li>On the right side panel, the SX-R4+ includes a 3M MDR 26-pin multipin connector that carries 4 \u00d7 AES3 inputs (AES 1\u20132 \/ 3\u20134 \/ 5\u20136 \/ 7\u20138) and the SX-R4+ command bus for system expansion.<\/li>\n<li>Internally, the recorder implements four independent AES receivers, each with its own ASRC, allowing connection of non-synchronized digital sources. These AES receivers can be allocated either to the 26-pin AES inputs or to the XLRs when configured as digital (AES3\/AES42).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Powering<\/strong><\/p>\n<ul>\n<li>Removable 14.4 V \/ 48 Wh smart battery (SMBUS capable)<\/li>\n<li>External 9\u201318 V DC on Hirose 4-pin, SMBUS capable and electrically isolated<\/li>\n<li>12 V regulated DC output for accessories (up to 7 W)<\/li>\n<\/ul>\n<p><strong>Expansion ecosystem\u00a0<\/strong><\/p>\n<ul>\n<li><strong>SX-AD8+ preamplifier: <\/strong>The SX-AD8+ expands the SX-R4+ input capability to up to 12 microphone inputs, enabling larger bag setups while keeping SONOSAX preamp quality across the rig.<\/li>\n<li><strong>SX-LC8+ linear fader control surface + USB MIDI controller:\u00a0<\/strong> The SX-LC8+ adds 8 linear faders with function switches for more comfortable mixing control in the field.

In addition, it provides power distribution (Hirose connectors), an additional headphone output, and a slate microphone capability.<\/li>\n<li><strong>SX-RX8+ wireless-focused expansion module: <\/strong>The SX-RX8+ is an 8-channel HF extension module designed to integrate multi-channel wireless workflows with the SX-R4+.
