WCLK IN & OUT (BNC)
The system can sync to external wordclock by connecting the clock signal to WCLK IN.
The WCLK OUT provides an output of the current system reference: PTP, WCLK IN, MADI or internal clock.
In both cases, connections are made using standard 75 ohm BNC connectors. The maximum cable length
depends on the equipment you are connecting to.

GPIO (SUB-D37)
The GPIO connector provides 8 x GPI (optocouplers) and 8 x GPO (silent and self-healing relays) for local
signaling and switched functions:
·
GPI = 8 x optocouplers (3-36V DC / 8mA @ 36V)
·
GPO = 8 x Opto-MOS relays (50V AC / 120mA @ 50V)
The connector is a 37-pin D-type.

DIGITAL & ANALOG IO
All rear panel IO cards break out on DB-25 connectors that are wired according to the AES59 (TASCAM)
standard (except for the STUDIO IO phones outputs).
All LINE IN and LINE OUT connections are electronically balanced. For LINE OUTs, the maximum analog level
can be adjusted to +12, +15, +18, +21 or +24 dBu relative to digital full scale (dBFS). This is a factory-
configured setting defined by the console edition: Fader Start (FS) = +15dBu, DIN; Button Start (BT) =
+24dBu, SMPTE.
Each of the MIC/LINE INs features a discrete class-A preamplifier with superb performance at both low (mic)
and high (line) levels. In addition to variable microphone pre-amp gain, each input comes with switchable 48V
phantom power, a high-pass filter and 20dB PAD. The pre-amp gain can be automatically adjusted using the
feature. The maximum analog input level (with the PAD enabled) is +24dBu.
All AES INPUTs and OUTPUTs conform to the stereo AES3 standard. The four AES INPUTs have sample rate
conversion (SRC).
