875HT Rear Panel INPUT/OUTPUT Connections

875HT EIGHT CHANNEL POWER AMPLIFIER

875HT REAR PANEL INPUT/OUTPUT CONNECTIONS

1Single Ended Input Connectors

This input connector for single-ended or un-balancedsignals accepts standard ‘RCA’ or ‘Phono’ connectors.

2 Balanced Input connector.

This input connector accepts standard 3 pin ‘XLR’ male connectors.

Pin 1 is signal ground

Pin 2 is positive phase (+) signal

Pin 3 is negative phase (-) signal

BALANCED vs SINGLE ENDED INPUTS

The balanced input requires a balanced pre-amp source. Balanced systems provide noise protection from external electrical interference, so cable length can be very long (50m or longer ). The single ended or unbalanced input is provided for pre-amps without balanced output. Single-ended cables should be kept to 20’ (7m) or less. In general never use longer cables than necessary, never coil excess cable length, and run signal wires away from AC power or speaker cables. Whether using balanced or un-balanced cables, use quality, 100% shielded cables with gold plated connectors.

Input Sensitivity:	P	Single-ended inputs:	850mV input for an output of 75W into 8 ohms
	P	Balanced inputs:	1.7V input for an output of 75W into 8 ohms

3Input Select Switch.

Each 875-HT channel gives the user the option of switching between either balanced input or single ended input.

4Input Level Control

Normal or maximum is fully clockwise. Minimum is fully counter clockwise which fully attenuates the input signal.

5STEREO/MONO SWITCH

LEVEL CONTROL

min. max.

The 875HT is configured as 4 stereo amplifiers. Each stereo pair has a Mono/Stereo switch. Stereo configures the chan nels as independent amplifiers with their own dedicated inputs. Mono configures the stereo pair as a single mono amplifier. The input comes only from the Mono labeled input and the speaker output connections are between the two hot (red) binding posts.

6OUTPUT BINDING POSTS

In STEREO mode: the RED binding post is connected

to the amplifier output. Connect to this post the (+) ter minal on the loudspeaker. The BLACK binding post is connected to signal ground. Connect to this post the (-) terminal on the loud speaker.

In MONO mode: both the RED binding posts are connected to amplifier outputs. The Odd Numbered channels (1, 3, 5 or 7) are the positive (+) phase output and the even numbered channels are the negative (-) phase output

The Output binding posts provide three different inter connect options. Combinations may be used when bi- wiring. See figure below. Cables should be kept as short as practical and should never be terminated with con nectors that may become confused for AC power con nectors. Cables should be dressed away from input and power cables.
