Trident 78 32 Channel 8 Buss Console

Trident 78 32 Channel 8 Buss Console is a 32-channel analog recording console in a split/inline architecture with eight subgroups — a semi-modular platform positioned below the fully modular Series 88, designed for recording studios, educational facilities, houses of worship, and live sound applications where the full per-channel modularity of the 88 is not required. It shares the 88's discrete Class A preamp and meter bridge design; the cost reduction comes from grouping channels into four-way panels rather than individual modules, which lowers manufacturing cost while maintaining serviceability at the panel level.

80B EQ and In-Line Architecture as the Recording Workflow Foundation

The equalizer section is taken directly from the Series 80B console — four bands consisting of two selectable shelving filters (high and low) and two swept parametric mid bands (low-mid and high-mid), with a switchable 50 Hz high-pass filter at 12 dB/octave operating independently. The EQ section has its own dedicated insert, allowing external processors to be patched directly into the EQ loop without disturbing any other part of the signal path. A selectable EQ path switch moves the full four-band EQ from the input path to the monitor path, doubling its utility at mixdown without additional cabling. In split/inline operation, each of the 32 channels runs two independent signal paths, yielding effectively 64 separately processed inputs feeding the stereo bus at mixdown.

Aux Routing and Bus Architecture

Six auxiliary sends per channel — four mono and one stereo (5/6) — each switchable pre or post fader independently. Stereo Aux 5/6 can additionally be routed to the monitor section, extending its utility for headphone or cue mix management. The eight subgroups are arranged in two panels of four, each group strip controlling its associated bus outputs; groups function as audio subgroups for bus compression or as additional summing outputs. All signal connections across the console use DB-25 connectors, with the exception of mic inputs (XLR) and main/speaker outputs (XLR) — a topology that eliminates individual cable management at the patch point and accelerates initial setup. The master section is built as a fully independent module, allowing it to be serviced or replaced without touching any input channel.

KEY FEATURES
