Toa A1806 60w 3 mic 3 aux zone selector and chime amplifier
€179.95 incl. 21% BTW
The A-1800 series are more sophisticated than TOA’s A-1000 and A-1700 series, offering more inter-connectivity options, such as inputs for paging, telephone and emergency signals, combined with features such as balanced inputs, remote control and AC/DC powering. Speaker outputs are to two zones, and offer 100V line or low impedance connection.
The front panel has level controls for three microphone inputs and three auxiliary inputs. There are bass and treble adjustments, master volume, LED level display and power switch with LED. Two switches select which zones are in use. LEDs show the status of the Emergency and Telephone functions. The rear has IEC power inlet; loudspeaker outputs using M4 screws; connectors for inputs and outputs. Two M4 terminals are for the connection of 24V DC power source. Microphones 1- 3, Aux 3 (mono) are connected using connectors combining XLR3 and 3-pole jack sockets. Aux 1 and Aux 2 inputs feature dual RCA (phono) connectors , mixing dual channel sources to mono. The record output also has dual RCA connectors to feed both channels of a stereo recording device. Two RCA connectors provide line out; by default they are both fed with the same signal as the power amplifier, but may be configured individually, internally, to follow the zone selection switches, such that line out 1/2 operates when Zone1/2 is active. A miniature (DIP) switch bank provides phantom power for microphone inputs 1 to 3 and sets operation of muting and chimes. A further terminal block provides connections for the emergency and telephone inputs, ‘Music on hold’ output, and control signals. Four rotary controls set levels for the music on hold output (fed by the signal on the Aux 1 input), emergency and telephone paging signals, chimes.
Microphone input 1 is equipped with a switch to divert the input connection to a 5-pin DIN connector. This allows the connection of a PM-660D paging microphone, which is fitted with a press to talk switch. Chimes can be set from none to four tones, for use with the paging mic facility and/or telephone announcements. Priority configuration is comprehensive, and the returning programme signal fades back smoothly.
