The 664 Field Production Mixer is the new flagship in Sound Devices line of portable audio mixers joining the 552, 302 and MixPre-D Sound Devices product. The 664 has six input channels and four output bus channels, all recordable for a total of 10-tracks. Other features include Ambient time code, intuitive menus via color LCD interface, multiple mic/line output configurations on XLR, 10-pin and TA-3 connectors, up to four channels of AES inputs (AES-3, AES42), and up to eight channels of AES3 outputs.

The CL-6 Input Expander is also available for applications requiring more inputs. It adds six line-level analog inputs, additional LED output metering and additional recording transport controls. The 664 with the CL-6 has 12 inputs and four output busses for 16 total record tracks. The direct output connectors on the 664 are selectable as inputs with the CL-6 attached.

FAQ:

Q: With the introduction of the 664, is the 552 discontinued?
A: No. The 552 continues in our field mixer product line. The 552 includes the benefits of five transformer-balance inputs, two-channel recording, excellent power efficiency, and relative simplicity. It is a very compelling product for many applications. The 552 continues to be the accepted industry standard for many applications where the 664 would simply be overkill.

Q: I love the sound of my 552 and 744T. Does the 664 use the same preamps?
A: The 664 preamps are a unique design, very similar to the transformerless 744T preamps.

Q: Are there transformers in the 664?
A: Yes. All of the XLR and Hirose analog and digital outputs are transformer-coupled. Transformers are highly effective in eliminating hum and noise in environments where battery and mains powered equipment is interconnected. While transformers add some weight, their benefit is significant for field mixers.

Q: How do the limiters sound and operate?
A: Just like all of Sound Devices field mixers, there are limiters at all gain stages (trim, fader, master) for worry-free mixing and recording. The limiters on the 664 are implemented 100% in analog via optoisolators and VCAs, taking action on the signal before it is converted to digital for recording. These analog limiters are very similar to the 442's limiters, sound superb and are tuned specifically for speech-oriented audio.

Q: Are signals summed in analog, like the rest of the mixer line, or digital, like the 7-Series?
A: The 664 offers both analog and digital summing. The input-to-mix and mix-to-analog outputs are all-analog signal paths. This provides for superb sonic performance. Top music engineers often use analog summing mixers for their sonic benefits versus "in the box" digital mixing.

Q: What happens with digital mics? Is their signal going through the mixer in analog or digital?
A: Either! AES42 inputs go through high-resolution sampling rate converters and are sent digitally to the DSP. When that signal is routed to a record track or to an AES output, it remains in digital. Signals in the DSP sent to analog outputs run through a DAC (digital-to-analog converter).

Q: How many channels can I record with the 664?
A: The 664 can record 10 tracks. Recording is very straight-forward - any or all of the 6 inputs can be recorded, as well as the L, R, X1, and X2 outputs.
When the CL-6 is connected, 16 tracks of recording are available: inputs 1-12, as well as outputs L, R, X1, and X2.

Q: I know that the 552 requires external time code to record with time code. Does the 664 have its own time code circuitry?
A: Yes, the 664 has a fully integrated Ambient Lockit generator and reader, just like the 788T recorder. It can operate as a master clock source, or its clock can be jammed from external sources. The 664 uses the same solid, ultra-accurate Ambient time code circuit that is used by Sound Devices, Arri Alexa, Ambient Lockits, and other high-end equipment.

Q: I have many wireless receivers. What if I need more than 6 inputs?
A: By connecting a CL-6 to the 664, 6 more inputs are available. Inputs 7-12 provide fully balanced line-level inputs. These inputs each provide a trim control, hardware fader, high-pass filter. These inputs can be sent to L, R, X1 and X2. All 6 of these inputs are recordable.

Q: How do I attach the CL-6? Is it difficult?
A: No. The CL-6 directly attaches to either the top or the bottom of the 664 using the CL-6's ribbon cable. Once connected, the direct outputs of the 664 can be changed to line-level inputs 7-12 via input menus.

Q: How many mix tracks can I create with the 664?
A: Four. Any input can be routed to any combination of L, R, X1, X2. All four of these mixes can be sent out to external cameras or other equipment, and they can be recorded to the CF and SD card. Additionally each input can be recorded.

Q: What if I need more than four mix tracks?
A: The 788T is the right tool when more than four mix tracks are required. It has full input-to-track and track-to-output routing capability for all tracks.
