Input:

The 9B has two inputs, one for a

balanced source,and one for

single ended or un-balanced

source. The BAL input connec

tor will accept either a 3 pin

‘XLR’ type or a 1/4” Tip/Ring/

Sleeve type. The in phase (+)

terminal is pin 2 on the ‘XLR’

and tip on the TRS. The input

impedance is 15K ohms. The

input pins are gold plated. Input

sensitivity is selectable using the

‘INPUT’ slide switch. In the ‘BAL

REG’ position 2 Volts in = 100

Watts / 8 ohms output. This is

the recommended setting when

using Bryston pre-amplifiers or

any pre-amplifier having active

balanced outputs. This setting

also produces the lowest ampli

fier noise floor.

The ‘BAL +6 dB” setting adds 6

db of gain to provide an input

sensitivity of 1 Volt in = 100

Watts / 8 ohms output. This set

ting is primarily for balanced out

puts that are transformer cou

pled, or other low level sources.

The ‘UNBAL’ setting selects the

gold plated ‘RCA’ type tip/sleeve

connector. The input impedance

is 50K ohms. The output is in

phase with the input and the

sensitivity is 1 Volt in = 100

Watts into 8 ohms output.

Balanced Vs Unbalanced:

Balanced cable interconnects should be used

whenever possible, as they provide common

mode noise protection from external electrical

interference, and with active balanced outputs

a 6 dB higher signal level flows in the cable.

The unbalanced cable interconnect is provided

for pre-amplifiers without balanced output. Un

balanced cables should be kept to 10 feet or

less. In general never use longer cables than

necessary, never coil excess cable length, and

run signal wires away from and never parallel

to AC power or speaker cables.

Output:

Gold plated output binding posts provide three

different interconnect options. Stripped bare

wire up to 8 Ga. can be passed through the

hole in the binding post and held in place by

tightening the post knob. Additional tightening

pressure can be achieved using a coin in the

slots of the knob. Copper wire is malleable and

may require further tightening a month or

two after initial installation. When using bare

wire watch out for fine wire fragments shorting

from one wire to the other.

Wire terminated with banana plugs,spade lugs,

or pins are also accommodated by the binding

posts. We recommend gold plated connectors

to prevent corrosion and signal distortion.

The red (+) binding post is the output and

normally will be connected to the red (+) con

nector on the loudspeaker. The black (-) bind

ing post is ground and should be connected to

the black (-) connector on the loudspeaker.

Speaker wire should be kept as short as practi

cal and should never be terminated with con

nectors that may become confused with AC

power connectors. Speaker cables should be

dressed away from input and power cables,

and even each other when runs are long.

The minimum speaker ioad on the

amplifier is 4 ohms.
