RW Manual-6

Off: Audio on this Port will not trigger the Port Signal

indicator on, nor will the Port be able to become the Master.

See also: Status Indicators on page Manual-4

Typical default value: Automatic

Port Auto-Level

Each Port has an independent selectable Limiter function:

Limiter: Use this on Ports containing speech, such as Port

1 or codec feeds. This Limiter is optimized with a fast attack

and a slow release. Once audio exceeds 0 dB on the Meter,

the Input attenuation is reduced to help prevent overload and

reduce the dynamic range.

Auto-Level: Use this on Ports containing speech and

music content. Auto-Level performs both the Limiter and an

Auto-Level function. Audio signals above 0 dB on the Meter

are reduced by the Limiter. If the audio exceeds 0 dB for 1

second, the Auto-Level kicks in. The Auto-Level function

calculates the average level and reduces the Input attenuation

by the same amount. This attenuation slowly releases only

when the Meter is between its set threshold level and -10 dB.

Off: This disables both of the above limiters.

Typical default value: Limiter radio button checked.

Port Threshold Level

Each Port has an independently adjustable Threshold

Level. The Port Threshold Level is used solely to illuminate

the Port Signal indicator and tell system status of which Port

contains audio. Once audio on a Port exceeds its Threshold

Level, the Port Signal indicator is lit (when the Port’s Signal

Mode is set to Automatic).

Typical default value: -20 dB

Port Input Level

Each Port has an independently adjustable Input Level.

Proper setup of the Input Level, particularly for video

CODECs, is perhaps the most important calibration proce-

dure to achieve optimum performance.

There are only a few (nominal) voltage reference levels

commonly seen on products in ECS applications.

• Devices with RCA jacks are generally considered -10 dBV

(0.316 Vrms) consumer-level devices. These include

VCRs, CD players, DVD, laserdiscs, and cassette decks.

• Many video codecs are rated at a nominal -10 dBm (0.245

Vrms into 600 ohms). These devices may require a 600

ohm resistor at the ECB 62e’s Input.

• Standard pro audio voltage reference levels equal +4 dBu

(1.23 Vrms).

Port Output indicators

These six indicators are green when the Port’s Output is

On (enabled). They are gray when the Port is off (muted).

The check box to the left of the Port name (just above the Port

Output attenuation sliders) turn the Port Outputs on (checked)

and off (unchecked).

Port Matrix check boxes

These 6 row by 6 column check boxes set the audio I/O

matrix of the ECB 62e. Each Input has an associated column

with the Input names shown from left to right across the top.

Each Output has an associated row with the names listed on

the right from top to bottom. Note: Only Port 5 allows its

Input to feed its own Output. This is useful for assisted

listening applications. Other than Port 5, Inputs cannot feed

their own Output to avoid feedback. See RaneNote 140,

“Mix-Minus Speech Reinforcement with Conferencing” for

room zoning applications using ECS.

For each Output row (names on the right), check the

corresponding Input box or boxes (columns) whose audio you

wish to mix into the chosen Output. For example, to mix the

room (mic) audio and a VCR on Port 5 and feed a mix of both

to a video CODEC on Port 2, in the second row down check

the first and fourth box from the left. [Note that the fourth

check box is actually in the fifth column since the second

column lacks a check box.]

Port Output Attenuators

Each Output has an independently adjustable Output

Attenuator. With the Attenuator set to 0.0 dB and with audio

producing a Meter reading of 0 dB, the Output will be 0 dBu

(0.775 Vrms).

The checkbox to the left of the Output names turns the

Port’s Output on (unmuted) and off (muted). When the check

box is checked, the Port Output “On” indicator is green.

Typical default value: Set to 0 dB for +4 dBu (pro/

balanced) devices. Set to 10 dB for VCRs, codecs, hybrids

and consumer level (RCA connector) devices.
