ECI Background:
The Electronic Cinema Interface (ECI) is designed to select a single input from a
variety of sources and then feed the selected source into a cinema processor. The
ECI provides inputs from 6 Channel Analog, 2 Channel Analog, 8 Channel Digital,
Toslink, and two SPDIF sources. The output is fed into the host cinema proces-
sor’s External Analog Input (6 Channels). A balanced 2 channel analog output of
AES channels 7 and 8 is provided.
Additionally, to synchronize the audio to the video source, each channel is capable
of up to 300ms delay. Input Delays – Each stage channel L, C, R, SW) is capable
of up to 200ms delay allowing for projector delay . Surround Delays - For the sur-
round channels (LS, RS), an additional delay of up to 100ms may be added to the
Input Delay. Delays can be confi gured for each type of input.
When a digital format is not selected an additional input allows a 6 channel analog
signal to bypass the ECI and be fed directly into the cinema processor’s External
Analog Input.
Input trim gains of up to 18dB may be added to the 2 and 6 Channel Analog Inputs.
There are no input trims on the digital inputs.
Output Trim attenuation of up to 20dB may be applied to each of the Digital
Modes.

Signal presence indicators – Indicates when signals are greater than -30dB.
2 Channel
Analog Indicator – Balanced line input.
The 2 inputs are fed to a Pro Logic II decoder which produces a
6 channel output.
6 Channel
Analog Indicator – Balanced line input.
All channels (L, C, R, SW
, Ls, Rs) are processed through the
unit.
8 Channel Digital Indicator –
AES Balanced line input.
The standard 6 channels are processed through the unit.
T
wo spare channels have independent balanced line outputs for use as needed.
T
oslink Indicator –
An optical
fi
ber connection for SPDIF (PCM) or
AC3 signals.
T
w
o channel PCM is decoded by
the Pro Logic II into 6 channels.
COAX 1 Indicator – Rear Panel RCA
type connector for SPDIF (PCM) or
AC3 signals.
T
wo channel PCM is decoded
by the Pro Logic II into 6 channels.
COAX 2 Indicator – Front Panel RCA
type connector for SPDIF (PCM) or
AC3 signals.
T
wo channel PCM is de-
coded by the Pro Logic II into 6 channels.
COAX 2 Input – RCA
type connector for SPDIF (PCM) or
AC3 signals.
Input Select switch (Front Panel) – Steps through the Input choices.
Film Mode Indicator – Lights when the unit is in Film (Bypass) Mode. Signals from
Analog Bypass Input pass directly
through the unit.
Digital Mode Indicator – Lights when the unit is in the Digital Mode. Signals from the selected digital input (item #9)
are processed through the unit.
Mode switch – Selects between Film or Digital Modes.
Power Indicator – Lights when unit is powered on.
Power Switch –
Applies power to the unit.
