User manual AUDIO TELEX SA60

[. . . ] Adjusting the bass control in a counter-clockwise direction will provide up to -12 dB of bass cut @ 100 Hz. Tfeble TOnal ContfOl: Setting this control in the centre o'zero" position will give an overall flat treble response to the output of the amplifier. Adjusting the treble control in a clockwise direction will provide up to +9 dB of treble boost @ l0 kHz. Adjusting the treble control in a counter-clockwise direction will provide up -9 dB of treble cut at 10 kHz. MaStef OUtpUt GOntfOl: This control adjusts the overall output level of the amplifier depending on the levels set for the individual input mix channels as detailed above. Start with the control level set to level 0 and slowly turn the control clockwise until the desired output level of the amplifier is reached. POWef SWitCh: This switch controls the switching of the AC power to the amplifier. [. . . ] Reading from left to right the terminals areLow Impedance Common 4 Ohms (SAl20 only. Not on 5460) 8 Ohms Constant Voltage Common 70 100 Z. Direct Output ConnectiOlsl r o o o r o . . Volt Line Volt Line Spare Spare Note: The minimum impedance level at any time on maximum load for 100 Volt line should be no less than 80 Ohms for the SAl20 and no less than 170 Ohms for the 5, 4, 60. 24 Volts DC Power Source Connectiolll Two post style terminals allow for the connection of an external 24VDC battery for applications where PA system operation is imperative. The red terminal post is for connection to the positive (+) terminal. The black terminal post is for connection to the negative O terminal. A trickle charge circuit provides a maximum 300mV automatically to a stand-by battery connected tothe24 VDC input on the SA120 only. 4. DC FUSe HOldef: Remove with a screwdriver and 5 Amps Slow Blow for the 5, 4. 60. if access is required. DC fuse rating is 10 Amps Slow Blow for the SA120 5. lnSeft TRS jack socket insert point (6. 5mm). Enables a graphic equaliser, FBX Feedback Exterminator or similar product to be connected. Unbalanced insertion, breaks normal connection between the pre-amp and power amp stages of the amplifier. Sleeve: Ground. 6. Tape OUtpUt 2 x RCA style phono output connector for line level output. Provides a maximum of 350mV into lOK Ohms, ideal for a connection to most standard tape recorders. This output is sourced before the master gain control and as such, the tape output level is not influenced by the operation ofthe master gain control. 7. Line OUtpUt Vtate XLR style, balanced transformer isolated output for connection to additional power amplifiers. Suitable for driving power amplifiers or similar devices. Ling lnputs: Note: AIt inputs are universal line / microphone inputs. Both connectors can not be utilised for any one input. Six pairs of RCA style phono input connectors accept unbalanced line or auxiliary inputs for channels I through 6. Channel 6 accepts higher level inputs such as a CD player. e. MiCfOphOne lnpUtS: Note: All inputs are universal line / microphone inputs. [. . . ] Installation should only be attempted by a qualified technician. Always turn off the AC power and remove the AC power cord before attempting to access the inside of the amplifier. Please contact your nearest Audio Telex oflice for details of your nearest qualified technician. g TOne GenefatOfS: Four separate tones are available as an option via the ATC5488 tone generator board. This internally mounted PCB is easily fitted and plugs directly into a socket provided on the intemal circuit board PCB6I78. [. . . ]
