This is a report for professionals with a suite of tests for line output devices. Alternative version of the report for "dummies" in development.

A suite of tests for the line-out can be used for headphone or speaker output if in this mode it is possible to use the device as a source for connecting an external amplifier or if such a test suite can give more information about the implementation of the DAC in the device.

Line-out, differences from the output for headphones and speakers

More detailed

Measurements of Ensoniq ES1370 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Ensoniq ES1370 test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

Комментарий к оглавлению отчетов Ensoniq ES1370

Когда происходил переход с шины ISA на PCI, почти все звуковые карты делались по стандарту AC97, с единственной доступной частотой воспроизведения в 48 кГц и посредственным неизбежным пересчетом 44.1 в 48 кГц.

Ensoniq ES1370 была редким исключением, т.к. поддерживала напрямую 44.1 кГц.

Комментарий к профессиональному отчету Ensoniq ES1370

Измерения линейного выхода проводились при понижении уровня на 1 дБ в foobar2000, т.к. при регулировке через микшер ОС (или драйвер) искажения лишь нарастали, а при полной амплитуде было клиппирование. Вывод звука через Kernel Streaming.

Комментарий к профессиональному отчету Ensoniq ES1370

При тестировании в режиме Speakers (к карте предполагалось подключать не столько наушники, сколько миниатюрные колонки) уровень был снижен на 11 дБ через foobar2000.
