ASA 204, ASA 304

Audio

Gain

Generally unity. Actual gain depends on whether or not both inputs have signals and also on the output wiring and DIP switch settings. See the table below.

Frequency response

20 Hz to 20 kHz, ±0.05 dB

THD + Noise

0.03% @ 1 kHz at nominal level

S/N

>90 dB (balanced) at rated maximum output

CMRR

>75 dB @ 20 Hz to 20 kHz

Number/signal type

ASA 204

4 stereo, unbalanced

ASA 304

4 stereo, balanced/unbalanced

Connectors

ASA 204

4 pairs of female RCA (tip-ring)

ASA 304

(4) 3.5 mm captive screw connectors, 5 pole

Impedance

ASA 204

>10k ohms unbalanced, DC coupled

ASA 304

>17k ohms unbalanced, 23k ohms balanced, DC coupled

Nominal level

ASA 204

-10 dBV (316 mV)

ASA 304

+4 dBu (1.23 V)

Maximum level

+20 dBu (7.75 V), (balanced or unbalanced), at 1% THD+N

NOTE

0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu

NOTE

All nominal levels are at ±10%.
