System
The bi-amplifi ed GENELEC HT206B, HT208B and HT210B are two way active speakers de signed for high quality Home Theater installations.
Drivers
The HT210B has a 250 mm (10") bass driver and the low frequency response extends down to 36 Hz (-6 dB). The HT208B has a 210 mm (8") bass driver with -6 dB point at 43 Hz and the HT206B a 170 mm (61/2") driver with -6 dB point at 47 Hz.
The high frequency driver is a 25 mm (1") (HT210B, HT208B) or a 19 mm (3/4") (HT206) metal dome. The uniform dispersion control is achieved with the rev o lu tion ary DCW technology pioneered by Genelec. The DCW also provides perfect phase and delay uniformity at the crossover frequency. The bass and treble drivers are magnetically shielded on all models.
Crossover
The amplifi er unit contains an active crosso­ver. This is the ideal method for di vid ing the input signal be tween the driver units, allow-
ing the over all response of the system to be optimized to an extent im pos si ble with a passive system.
To main tain uniform fre quen cy bal ance in dif fer ing acoustic en vi ron ments, three switch groups are included in the active cross over network: treble and bass 'tilt' and bass 'roll­off' switches, which make ad just ments in 2 dB steps.
Amplifiers
The amplifi er unit is mounted to the rear of the speaker enclosure. It includes individual power amplifi ers for each speaker driver, 120+180 watts on the HT210B, 120+120 W on the HT208B and 50+80 W on the HT206B for the treble and bass drivers respectively. The amplifi ers incorporate protection circuitry for driver overload protection and amplifi er thermal overload protection. Variable input sensitivity allows for accurate level match­ing with the decoder or preamplifi er output section.
The amplifi ers are equipped with an “autostart” function for automatic switching between “standby” and “on” power modes. The power mode can also be changed with a 12 V trigger voltage or external switch type remote control. An indicator LED on the DCW plate shows the system status.
"Autostart" and "remote control" functions can be enabled or disabled as required by using the switches on the speaker back panel.
Installation
Place the loud speakers in their required positions and aim them towards the center of the listening area. Do not place the speaker in a horizontal position as this may cause acoustical cancellation problems around the crossover frequency.
Suffi cient cooling for the amplifi er must be ensured if the speaker is installed in a restricted space such as a cabinet or inte­grated into a wall structure. The minimum clearance for the amplifi er is 10 cm (4") to any object. The space adjacent to the ampli­fi er must either be ventilated or suffi ciently large to dissipate heat so that the ambient temperature does not rise above 35 degrees Celsius (95°F).
Before con nect ing up, ensure that the mains switch is set to "OFF". Check that the mains voltage selector is set to your local voltage.
Audio input is made via a 10 kOhm bal­anced (XLR) or unbalanced (RCA) connec­tor. If the signal source has suitab le balanced outputs, we recommend the use of XLR con­nectors and balanced interconnect cables due to their better resistance to interference. Once connection has been made, the speak­ers are ready to be pow ered up.
Setting the input sensitivity
The input sensitivity of Genelec HT series speakers can be matched to the decoder output section or other source by using the
