| ULTIMATE series A4 is a powerful 4-channel amplifier
rated at 4 x 50 Watts. Provides a typical output of 4 x 85 Watts
with 4-ohm stereo and 2 x 250/400 Watts with 4/2-ohm mono bridge-connection.
Built-in variable 50-125 Hz. low-pass filter for subwoofers
on all channels. Additionally, a built-in variable 20-200 Hz
high-pass filter that can be used as a subsonic filter or high-pass
filter for front systems. The frequency can be switched on the
filter so that two of the channels can be used for mid-range
woofers. |
