User manual GENELEC HT206B

[. . . ] Variable input sensitivity allows for accurate level matching with the decoder or preamplifier output section. The amplifiers 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. [. . . ] The bass and treble drivers are magnetically shielded on all models. Crossover The amplifier unit contains an active crossover. This is the ideal method for dividing the input signal between the driver units, allow- 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 Figure 2. Switch and connector layout on the amplifier panel. HT208B shown. input sensitivity control on the rear panel (see figure 1). A small screwdriver is needed for the adjustment. The manufacturer's default setting for this control is -6 dBu (fully clockwise) which gives a sound pressure of 100 dB @1m with -6 dBu input level. Note that to get the full output level of 110 dB SPL, an input level of +4 dBu is needed in this setting. deactivated by turning the "AUTOSTART" dip switch to "OFF". The amplifier mode can also be switched by a remote control unit connected to the respective inputs on the amplifier. Two pairs of connectors are provided, 1 and 2 for a 12 V DC type remote control, and 3 and 4 for an external switch or relay type control. Do not connect two remote controls to the to the speaker at the same time. Activate the function by turning the "REMOTE CONTROL" dip switch on the amplifier panel to "ON". Note that the remote control overrides the "autostart" function. may only be undertaken by qualified service personnel. Safety considerations 1. Servicing and adjustment must only be performed by qualified service personnel. Opening the amplifier's rear panel is strictly prohibited. It is forbidden to use this product with an unearthed mains cable, which may lead to personal injury. To prevent fire or electric shock, do not expose the unit to water or moisture. Do not place any objects filled with liquid, such as vases on the speaker or near it. Note that the amplifier is not completely disconnected from the AC mains service unless the mains power cord is removed from the amplifier or the mains outlet. This equipment is capable of delivering Sound Pressure Levels in excess of 85 dB, which may cause permanent hearing damage. Setting the tone controls The acoustic response of the system may also have to be adjusted to match the acoustic environment. The adjustment is done by setting the three tone control switch groups 'treble tilt', 'bass tilt' and 'bass roll-off' on the rear panel of the amplifier. [. . . ] Both of these switches should always be set to the same position. Autostart and remote control The amplifiers are equipped with an "Autostart" function, which automatically turns the amplifier to "standby" mode if an input signal has not been detected for approximately five minutes, and back to "on" mode when the signal returns. The function can be Guarantee This product is supplied with a two year guarantee against manufacturing faults or Maintenance There are no user serviceable parts within the speaker. Any maintenance or repair defects that might alter the performance of the unit. Refer to supplier for full sales and guarantee terms.
