API 1608-II Recording and Mixing Console
BASIC 16-CHANNEL API AUDIO 1608-II CONSOLE SPECS
The API Audio 1608-II features a single audio path design, perfect for analog tracking, routing and monitoring, as well as:
- 16 Channels of Input, each with EQ & Mic Preamp
- 16 Faders (with optional automation)
- 8 Auxiliary Buses
- 8 Summing Buses
- 4 Stereo Returns (automatable)
- 1 Stereo Bus
- 8 Spaces for any VPR Alliance 500 Series module
CHANNEL YOUR ENERGY
Each channel of the API Audio 1608-II consists of one signal path for tracking or mixing. The core of each channel is the 548C Channel module, which provides for a variety of functions. The combination of the 16 channels, the 4 Stereo Returns, and the 8 Summing Bus masters provides 32 channels of audio for mixdown via the Program Bus.
The 548C Channel module provides everything you need to track and assign your audio signals. Employing a variation on the classic API 212L mic pre, the preamp section provides the essential tools of 48v phantom power, polarity reversal, a -20dB pad, a peak output LED, and up to +55dB of gain.
The default signal to the 548C preamp section is the balanced, low-impedance Line Input, which can be hit with a -6dB pad before it flows to the classic API 550A equalizer. At this point the channel Insert Send/Return can be utilized, operating post-EQ and pre-fader. The signal can then be run through a High Pass Filter of -3dB at 50Hz (with a 6dB/octave slope). The signal can be Soloed or Muted as necessary, and even assigned to a Mute Group.
By default, the 548C feeds the Direct Outputs on the rear panel D-sub connector, with a post-fader, balanced, line-level signal (this can be calibrated with the Trim-pot). The audio signal can simultaneously be panned between the Left & Right Program Buses or the Odd & Even selections of the 8 Summing Buses (when engaged).
For expanded versatility, the 548C Channel Module provides for 8 Auxiliary Sends. The Auxes are 4 mono and 2 stereo sends, each with level control, an ON/off switch (illuminated), and a pan pot for the stereo sends. All of the sends can be either pre- or post-fader. Aux Send 7/8 can also be routed directly to the Summing Buses 1-4.
CROSSING THAT BRIDGE
The API Audio 1608-II provides a meter bridge with full analog VU metering, in a classic black/red scale on a yellow background for easy visibility. All Input channels have a medium-size VU meter, with the first 8 doubling as meters for the Summing Buses. Over the Master Section, the 8 Auxes & 4 Stereo Returns have their own set of small meters, while the Stereo Program Bus is displayed on the largest pair. All meters are illuminated.
The 840C multi-function routing module provides the controls for the channel VU meters. The source for the channel meters can be either the Direct Output, Line Input, or Mic Preamp. The VU CH button cycles through these three options, which are indicated by an LED. Selecting VU BUS instead will display the output of the Summing Buses.
The 265C module provides a choice between using the 8 small VU meters for the 4 Stereo Returns (the default setting), or the 8 Auxiliary Sends.
The 845C Monitor Control module selects the source for the Main Stereo Meters; the default is the stereo program master, while the Aux Sends and Solo Bus can also be displayed, as well as 6-Track playback.
The Meter Bridge is completed by LED indicators for the power supply voltages, as well as a built-in talkback microphone.
MASTER OF YOUR OWN DOMAIN
The API 1608-II has a comprehensive Master Section that allows you to control and process your signals for both tracking and mixing. This section houses the controls for:
- Stereo Returns
- Auxiliary Sends
- Summing Buses
- Solo Bus
- Control Room monitoring functions
Key to the processing and color of your sound are the four Stereo Returns located on the 265C module; these can take their input from either a D-sub Line Level (default), the eight internal Auxiliary Buses, or the eight 500 Series slots in the Master Section. These inputs can be summed to Mono, after which a Stereo Insert Return is also available. This is followed by a 100mm long-throw fader, with up to +10dB of gain. The post-fader output is mutable, and can be assigned to the Program Bus or to the Summing Buses 7 & 8.
To maximize the utility of the Stereo Returns, load the 500 Series modules of your choice for compression, limiting and tone shaping of every description. These modules can be used in pairs in conjunction with the Stereo Returns, or as individually patchable processors. Complement the classic tone of the API mic pre/EQ with even more sonic sculpting.
The remainder of the 265C module contains the 8 Auxiliary Sends. These are situated in four pairs above their associated Stereo Returns (sends 1-2 are Stereo Return 1, etc). The Aux Sends have their own ON/off switch, and provide for an External Input, Level control up to +6dB, Solo control, Talkback insertion (headphone feeds), VU meter routing, and a balanced, line-level output from the D-sub connector.
API Audio’s 168C Summing Bus Module contains the routing and control for all 8 buses, as well as an external input to the Program Bus. Each Summing Bus has its own on/off switch, Level pot (up to unity gain), Solo button, and assignments for the Left & Right Program Buses (these can be overridden by the rear panel ¼” TRS input switching jacks).
CONTROL ROOM MONITOR
For the flexibility you’ll need to route and monitor for tracking and mixing, the 845C Control Room Monitor Control is the ultimate tool. Choose a Source to monitor from among the Program Bus, Aux Sends, or external 6-track playback for 5.1 monitoring. These are fed to the output control section, where it can be switched off, attenuated via the Dim Level pot, summed to Mono, and routed to the Main speakers, as well as two Alternative monitoring systems.
From there, the 268C Output Master takes over. The 268C’s six individual Monitor outs can be switched on/off, as well as allowing calibration of the trim pots before final send to the rear panel Control Room Output connectors.
AUTOMATE FOR LIFE
The 1608-II can be ordered with an optional Final Touch™ moving-fader and switch automation system, or added later as an upgrade. Final Touch™ is a cross-platform system that provides moving faders and automated Mute or Insert for all Channels, Stereo Returns and the Program Master, as well as 2 automated Control Group Masters, and MIDI and SMPTE timecode synchronization. A built-in computer and touchscreen provide the interface, and no external computer is required.
BRINGING UP THE REAR
The rear panel of the 1608-II has all the connectivity you need to interface with your studio equipment:
- 3-pin XLRs provide the Inputs for Microphone, Line, and 6-track playback; and L/R Outputs for the Program Bus, Alt 1 & 2 Control Room Monitors, and the 5.1 surround channels.
- 25-pin D-sub connectors provide the Direct Outs, Aux Send and Bus Mix Outs, and the Inputs for the Stereo Return and the 6-track playback, as well as all of the Alt Line Inputs to each channel.
- ¼” TRS jacks provide for all the Send/Return patching of the 1608-II. They are used for both the Large and Small Fader Path Sends & Returns; the Bus Mix Input, the Aux Sends External Input, the Stereo Return Inserts, the Return 500 Series slots, and the Program Bus Insert Send/Return.
Various ports provide for interfacing with MIDI, HDMI, USB, SMPTE and Automation.
AN ECHO RETURNS
It’s been a decade since API introduced the 1608 console. Since that time, it’s found a home in hundreds of studios around the world. Engineers and producers looking for an all-analog desk with a small footprint have made the 1608 one of the most popular consoles around.
Now it’s time to update the functionality, while keeping the core API sound that users have come to know and love. One of the primary upgrades, in response to customer workflows, has been to change the 8 mono Echo Sends into four sets of Stereo Returns. Also available is an automation system that will interface with all other API consoles, making your sessions very portable.
With its upgraded functionality, slots for customizing your modules, and all the in-your-face tone of a classic API Audio console, now is the time to look into a new 1608-II with 16 channels,32 channels or 48 channels.
