Trident 78 24-channel Console with LED Meter Bridge

The Trident 78 all analog consoles are all Trident through and through.

The Trident 78 is a cost effective mixing console tailored for engineers, studio owners, educational facilities, houses of worship, and live sound applications.

The 78’s are Split/lnline consoles with individual channels in 4-way panels. Using an 8 subgroup configuration and incorporating 6 Aux sends, its routing options are vast and simple to use. Connections are fast and easy with DB-25’s throughout the board and XLR’s for speaker and main outputs.

With the 80B EQ at its core, including selectable channel inserts and discrete preamps driving the inputs, the Trident 78 consoles offer a wide array of summing and mixing options. The uncompromised sonic quality and compact footprint of the 78’s are able to meet any demand.

Features found throughout the 78 make for a straightforward and powerful package, but paramount to all else is The Sound. Among the many styles, preferences and methods of recording exists the expectation that a board must have the ability to be pushed hard and sound big. This is a hallmark of the series 80 consoles and the 78 carries that tradition forward.

Bottom line: The Trident 78 was created with all of this in mind so that you can use it to make great sounding tracks.

Modularity Throughout

The 78’s by design are manufactured to be a more cost effective variant of the fully modular 88’s. Incorporating a similar chassis design and the same meter bridge, the 78’s have a rugged and proven core. Using a simi-modular design the 78’s are able to effectively reduce their overall costs without a significant sacrifice to serviceability.

• All input channels are individual boards, faders included, each in a 4 channel panel.
• Subgroups are individual boards, faders included, each in a 4 channel pack.
• Master Channel is an individual channel separated from all others.

Split/Inline Console:

Since the inception of this configuration by Trident Audio on the A-Range console in the late 1960’s it has been adopted throughout the industry and remains a standard configuration for our consoles today.

• Dual Inputs to the channels with line and monitor inputs
• 4 Band EQ with sweeping mid bands and selectable low and high bands
• 27dB of headroom
• Channel Inserts
• Selectable EQ Path

Microphone Preamp:

The 78’s incorporate the same high quality Class A Discrete preamp as the 88’s. These preamps have lots of headroom and high gain fully capable of driving ribbon microphones.

• 60dB gain preamp
• Balanced inputs
• Balanced inserts with full bypass
• Input Reverse Switch
• Mic/Line Switch
• Phantom Power Switch

Powerful EQ:

The 78’s incorporate the iconic Series 80B console EQ as the main channel EQ throughout the console. This EQ is known throughout the industry for its musicality and ease of use.

• Selectable high bands at 8k and 12k
• Sweepable High and Low Mid
• Selectable low bands at 60Hz and 120Hz
• 50Hz High Pass Filter
• Selectable Channel Insert

Master Section:

The master section of the 78’s are laid out for ease of use and have all the necessary features to manage your monitors, talkback, and stereo returns.
The 78’s master section is an independent channel from the rest of console to ensure that your console’s master output functions can be easily and quickly serviced with little or no downtime.

EQ

The Series 78 incorporates the classic four band equaliser which is identical to that employed in the Trident Series 80B console. It consists of frequency switchable high and low pass shelving sections, coupled with two swept low and high mid range bands and a switchable 50Hz, 12dB per octave filter. Furthermore the EQ has its own independent Insert. Either bypass the EQ or use any other outboard EQ or device in conjunction with each other.

Master Section

The master section features 6 AUX Masters each with Solo. AFL/PFL Master with level adjustment. In addition to the main speaker outputs there is also a separate ALT Monitor, each with level control, DIM, and on/off switches. The Monitor section allows the return of 2 separate stereo signals direct into the master section with level and mute. Or plug your portable device directly into the panel with a top mounted 1/8th inch TRS input. Through Talkback control you can talkback to the Auxes or the groups. Using either the onboard talkback mic or an external mic.

Monitor Section
The Trident 78 is a split in-line console. This means you can switch the inputs on each channel providing an easy workflow when tracking and mixing.

Aux Section
The Trident 78 features 6 Aux sends all with pre or post fade selection, accessible on every channel. Stereo Aux 5/6 can also be sent to the Monitor section.
