6.2 Analog Outputs

The 8 short circuit protected, low impedance and servo balanced line outputs are available as

(stereo) 1/4" TRS jacks and 25 pin D-sub jack. Both are internally connected, and - in contrary

to the inputs - can be used simultaneously. The electronic output stage is built in a servo bal-

anced design which handles monaural and stereo jacks correctly. When used unbalanced it

automatically corrects the gain by 6 dB.

The 25-pin D-sub connector follows the pinout known from devices manufactured by Tascam.

Refer to chapter 11 for a pinout listing. We do not recommend to make such a cable by your-

self, as it is extremely difficult to integrate 8 balanced lines into a small D-sub housing without

shorts. Your dealer will be glad to provide you with a professional Tascam multicore, D-sub to

XLR, made in the length of your choice.

To maintain an optimum level for devices connected to the analog outputs the ADI-8 PRO

includes electronic switches of the newest technology, which introduce no additional noise or

distortion to the audio path. The key OUTPUT LEVEL allows to change the output level of all 8

channels simultaneous to the most often used -10 dBV and +4 dBu.

Each analog output has its own 'Signal Ok' LED, so a signal at the analog outputs is visually

indicated. The green LED begins to light at -40 dBFS in an analog fashion (brighter at higher

levels).

As with the analog inputs the analog output levels do not follow any single standard, but are

designed to maintain a problem-free operation with most other devices. The headroom of the

ADI-8 PRO is defined according to the chosen reference level.

Reference 0 dBFS @ Headroom

Hi Gain +19 dBu 15 dB

+4 dBu +13 dBu 9 dB

-10 dBV +2 dBV 12 dB

At +4 dBu a headroom of 9 dB offers a problem-free operation with most devices, and meets

the latest EBU recommendations for Broadcast usage. At -10 dBV 12 to 15 dB headroom are

common practice, each mixing desk operating at -10 dBV is able to send and receive much

higher levels. Hi Gain results in maximum level for professional users who prefer to work bal-

anced and at highest levels.
